En raison de son effet synergique exceptionnel et de sa capacit\u00e9 \u00e0 r\u00e9duire de mani\u00e8re stable le vieillissement de la r\u00e9sine, il joue un r\u00f4le plus important dans la production de caoutchouc et de r\u00e9sines synth\u00e9tiques, de sorte que le mat\u00e9riau polym\u00e8re est plus durable. La plus grande caract\u00e9ristique de l'antioxydant 3052 est sa capacit\u00e9 \u00e0 r\u00e9sister \u00e0 l'oxyg\u00e8ne thermique \u00e0 haute temp\u00e9rature, qui est un composant n\u00e9cessaire dans les additifs des mat\u00e9riaux polym\u00e8res, en particulier dans des conditions de faible teneur en oxyg\u00e8ne peut jouer un r\u00f4le plus important.<\/p>\n<p>2, l'antioxydant 3052 est un nouveau type d'antioxydant, tr\u00e8s efficace pour pr\u00e9venir le vieillissement thermo-oxydant des polym\u00e8res, car sa mol\u00e9cule poss\u00e8de deux groupes actifs, l'hydroxyle ph\u00e9nolique et l'acrylate, et peut contr\u00f4ler efficacement le moulage en gel de l'homopolym\u00e8re et du copolym\u00e8re butadi\u00e8ne, en particulier dans le traitement \u00e0 haute temp\u00e9rature de la teneur en oxyg\u00e8ne des conditions les plus faibles, son effet protecteur est plus important. Par cons\u00e9quent, il a une capacit\u00e9 antioxydante \u00e9lev\u00e9e, une non-d\u00e9coloration, une faible volatilit\u00e9 et une excellente r\u00e9sistance \u00e0 l'extraction, son champ d'application est \u00e9galement extr\u00eamement large, il peut \u00eatre appliqu\u00e9 \u00e0 l'industrie du caoutchouc synth\u00e9tique, aux adh\u00e9sifs thermofusibles, aux \u00e9lastom\u00e8res, aux mat\u00e9riaux d'emballage en contact avec les aliments et les m\u00e9dicaments et \u00e0 d'autres domaines, mais aussi dans le domaine de l'industrie auxiliaire dans le type de produits le plus important.<\/p>\n<p>3. L'antioxydant 3052, les antioxydants \u00e0 base d'esters de soufre et les antioxydants \u00e0 base de phosphite ont un bon effet synergique lorsqu'ils sont utilis\u00e9s conjointement, et sont g\u00e9n\u00e9ralement utilis\u00e9s conjointement avec des antioxydants \u00e0 base d'amines encombr\u00e9es et des absorbeurs d'UV \u00e0 base de benzotriazole. Par rapport \u00e0 l'antioxydant traditionnel de type bisph\u00e9nolique 2246, l'antioxydant 3052 a un point de fusion plus \u00e9lev\u00e9 et peut r\u00e9sister \u00e0 des temp\u00e9ratures plus \u00e9lev\u00e9es.<\/p>\n<p>4, il existe actuellement deux m\u00e9thodes de synth\u00e8se de l'antioxydant 3052. Il s'agit de la synth\u00e8se \u00e9tape par \u00e9tape et de la synth\u00e8se par la m\u00e9thode \"one-pot\". La synth\u00e8se \u00e9tape par \u00e9tape se divise en deux parties : une sorte d'acide organique, l'oxyde de chlore et de phosphore, la synth\u00e8se du chlorure de chlore, puis la pr\u00e9paration de l'antioxydant \u00e0 partir du chlorure de chlore et du bisph\u00e9nol ; cette m\u00e9thode de pr\u00e9paration et de synth\u00e8se a d'abord \u00e9t\u00e9 mise au point par la soci\u00e9t\u00e9 japonaise Sumitomo Chemical Company, avant d'\u00eatre largement utilis\u00e9e. Une autre m\u00e9thode consiste \u00e0 pr\u00e9parer des antioxydants \u00e0 partir de bisph\u00e9nol, de chlorure d'acide chlorique et de bases organiques ; elle a \u00e9t\u00e9 mise au point par Sumitomo Chemical pour synth\u00e9tiser de tels antioxydants. La synth\u00e8se en une seule \u00e9tape implique la pr\u00e9paration de compos\u00e9s chlor\u00e9s \u00e0 partir de bisph\u00e9nol, d'acide carboxylique et de phosg\u00e8ne solide, avec des bases organiques comme catalyseurs. \u00c0 la fin de la r\u00e9action, sans s\u00e9paration, une certaine quantit\u00e9 de solvant organique est ajout\u00e9e directement, puis une solution de bisph\u00e9nol contenant le solvant des selles est ajout\u00e9e goutte \u00e0 goutte, et la r\u00e9action se poursuit \u00e0 une certaine temp\u00e9rature pendant un certain temps. \u00c0 la fin de la r\u00e9action, le pr\u00e9cipit\u00e9 est \u00e9limin\u00e9 par filtration sous pression r\u00e9duite et le solvant est \u00e9limin\u00e9 par distillation \u00e0 la pression atmosph\u00e9rique. La pr\u00e9cipitation des cristaux, la mati\u00e8re cristalline par recristallisation, la filtration et le s\u00e9chage d'un solide blanc, c'est-\u00e0-dire un nouveau type de produits antioxydants \u00e0 base de monoester de bisph\u00e9nol.<\/p>\n<p>5, dans le processus de pr\u00e9paration traditionnel, vous devez pr\u00e9parer l'interm\u00e9diaire 2,2\u2032-m\u00e9thyl\u00e8ne bis (4-m\u00e9thyl-6-tert-butylph\u00e9nol), \u00e0 l'origine ph\u00e9nol hydroxyle et anneau aromatique pour former un effet de conjugaison r\u00e9duit l'atome d'oxyg\u00e8ne sur la densit\u00e9 du nuage d'\u00e9lectrons, de sorte que la performance nucl\u00e9ophile ph\u00e9nol hydroxyle est faible, ne peut pas \u00eatre est\u00e9rifi\u00e9 avec des acides carboxyliques directement, En m\u00eame temps, lorsqu'on acc\u00e8de \u00e0 un groupe important sur l'anneau benz\u00e9nique du 2-tert-butyl-4-m\u00e9thylph\u00e9nol, un effet spatial r\u00e9duira encore l'activit\u00e9 du groupe hydroxyle ph\u00e9nolique, ce qui rendra le processus de pr\u00e9paration plus difficile. En outre, dans le processus conventionnel de synth\u00e8se de l'antioxydant 3052, quelle que soit la m\u00e9thode contourn\u00e9e en utilisant du chlorure d'acide chlorique comme mati\u00e8re premi\u00e8re, de l'alcali organique comme agent de liaison acide et catalyseur, l'alcali organique se transforme en sel organique pour devenir un d\u00e9chet solide, en plus de la m\u00e9thode conventionnelle de pr\u00e9paration produira de l'acide chlorhydrique, doit ajouter de la tri\u00e9thylamine pour \u00e9liminer l'acide chlorhydrique, ce qui conduit \u00e0 un grand nombre de d\u00e9chets solides de chlorhydrate de tri\u00e9thylamine, il y a des irritants dans le processus de production, des d\u00e9chets solides et d'autres d\u00e9fauts.<\/p>\n<p>L'agent liant les acides utilis\u00e9 dans la synth\u00e8se du 2-(2-hydroxy-3-tert-butyl-5-m\u00e9thylbenzyl)-4-m\u00e9thyl-6-tert-butylph\u00e9nyl acrylate (antioxydant 3052) est principalement la tri\u00e9thylamine, mais lorsque la tri\u00e9thylamine est utilis\u00e9e comme agent liant les acides, non seulement elle r\u00e9agit avec le chlorure d'acryloyle pour inactiver le chlorure d'acryloyle, mais elle pr\u00e9sente \u00e9galement une forte alcalinit\u00e9, ce qui entra\u00eenera une est\u00e9rification suppl\u00e9mentaire du produit pour produire des diesters d'acide acrylique et d'autres sous-produits. Les r\u00e9sultats ont montr\u00e9 que la combinaison de pyridine, de Na2CO3 et de tri\u00e9thylamine en tant qu'agent liant les acides mixtes r\u00e9duisait consid\u00e9rablement la production de sous-produits, et que la s\u00e9lectivit\u00e9 des mati\u00e8res premi\u00e8res \u00e9tait sup\u00e9rieure \u00e0 97%, et que le rendement atteignait 80%. Lorsque les \u00e9chantillons 3052 synth\u00e9tis\u00e9s ont \u00e9t\u00e9 ajout\u00e9s \u00e0 la production de r\u00e9sine ABS, la valeur d'aberration chromatique \u0394E \u00e9tait inf\u00e9rieure \u00e0 2,0 et a atteint la norme qualifi\u00e9e de l'industrie. La diff\u00e9rence de couleur \u0394E de l'\u00e9chantillon 3052 synth\u00e9tis\u00e9 est inf\u00e9rieure \u00e0 2,0, ce qui correspond \u00e0 la norme industrielle.<\/p>\n<p>&nbsp;<\/p>\n<p><img

L'utilisation de bases organiques ou inorganiques comme liants acides entra\u00eene la formation d'un grand nombre de sous-produits tels que les sels de sodium, de potassium ou d'amine.

La production \u00e0 grande \u00e9chelle et la synth\u00e8se verte des liquides ioniques sont encore limit\u00e9es par la technologie et le processus.<\/p>\n<p>&nbsp;<\/p>\n<p>Figure 2 : S\u00e9paration simple de produits \u00e0 l'aide de liquides ioniques comme agents de liaison acides<\/p>\n<p>\uff5cR\u00e9sine alcaline \u00e9changeuse d'ions<\/p>\n<p>Les r\u00e9sines basiques \u00e9changeuses d'anions sont \u00e9galement utilis\u00e9es pour tenter de jouer le r\u00f4le de liants acides dans les r\u00e9actions. La r\u00e9sine est extr\u00eamement facile \u00e0 s\u00e9parer du syst\u00e8me r\u00e9actionnel et est facilement r\u00e9g\u00e9n\u00e9r\u00e9e sans rester dans le produit. Dans le cas de la synth\u00e8se de l'ADC (di\u00e9thyl\u00e8ne glycol bicarbonyl di\u00e9nophtalate), par exemple, la r\u00e9sine \u00e9changeuse d'ions basique solide est utilis\u00e9e comme agent liant les acides, ce qui emp\u00eache l'hydrolyse de la mati\u00e8re premi\u00e8re sous l'effet de l'alcali liquide et consomme la mati\u00e8re premi\u00e8re ; en m\u00eame temps, cette m\u00e9thode am\u00e9liore le rendement et la puret\u00e9 du produit et stabilise sa qualit\u00e9.<br \/>\nLa recherche et l'application de la r\u00e9sine \u00e9changeuse d'ions en tant qu'agent liant les acides sont encore relativement limit\u00e9es, la capacit\u00e9 d'\u00e9change des groupes fonctionnels alcalins, le transfert de masse par diffusion dans la r\u00e9action, etc. n\u00e9cessitent davantage de donn\u00e9es scientifiques et d'exp\u00e9rience en mati\u00e8re d'industrialisation.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>Le choix des liants acides est souvent ax\u00e9 sur le rendement du produit, puis sur la combinaison de son alcalinit\u00e9, de sa stabilit\u00e9, de son point d'\u00e9bullition et d'autres aspects. Les liants acides verts doivent \u00eatre caract\u00e9ris\u00e9s par une faible toxicit\u00e9, un recyclage multiple et une s\u00e9paration facile afin de r\u00e9aliser une production verte d\u00e8s le d\u00e9but du processus de r\u00e9action.<\/p>\n<h1><strong><b>Contactez-nous d\u00e8s maintenant !<\/b><\/strong><\/h1>\n<h4><strong><b>Si vous avez besoin de Price, veuillez indiquer vos coordonn\u00e9es dans le formulaire ci-dessous.

topics<\/h2>\n<p>Most wastewater-treatment problems are system problems.
