Le TBC a une bonne compatibilit\u00e9 avec la r\u00e9sine de vinyle, l'ac\u00e9tylbutyrate de cellulose, l'ac\u00e9tate de cellulose, la cellulose de benzyle, l'\u00e9thylcellulose, etc. et est un bon plastifiant avec une meilleure efficacit\u00e9 de plastification. Plastifiant ; le TBC pr\u00e9sente \u00e9galement les caract\u00e9ristiques suivantes : antibact\u00e9rien sans d\u00e9veloppement de bact\u00e9ries, non irritant, ignifuge et d\u00e9gradable.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">M\u00e9thode de pr\u00e9paration du TBC<\/h2>\r\n\r\n\r\n\r\n<p>L'acide citrique et le n-butanol r\u00e9agissent en pr\u00e9sence d'un catalyseur et d'un agent porteur d'eau pour g\u00e9n\u00e9rer du citrate de tributyle, et le produit est obtenu par des proc\u00e9d\u00e9s tels que la d\u00e9salcoolisation, la neutralisation, le lavage \u00e0 l'eau, le d\u00e9capage \u00e0 la vapeur, la d\u00e9coloration et le filtre-presse.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Principe de la r\u00e9action TBC<\/h2>\r\n\r\n\r\n\r\n<p>Le citrate de tributyle peut \u00eatre synth\u00e9tis\u00e9 par la r\u00e9action d'est\u00e9rification de l'acide citrique et du n-butanol. Les catalyseurs d'est\u00e9rification traditionnels sont des acides forts tels que l'acide sulfurique et l'acide benz\u00e8nesulfonique, qui sont peu co\u00fbteux et ont une activit\u00e9 catalytique \u00e9lev\u00e9e, mais qui entra\u00eenent de nombreuses r\u00e9actions secondaires, un post-traitement compliqu\u00e9, une forte corrosion des \u00e9quipements et des \u00e9missions d'acides r\u00e9siduels qui polluent gravement l'environnement. C'est pourquoi la synth\u00e8se de produits esters non catalys\u00e9e par des acides est un objectif de recherche \u00e0 long terme. De nombreuses \u00e9tudes ont \u00e9t\u00e9 men\u00e9es sur l'acide h\u00e9t\u00e9ropolylique support\u00e9 par le charbon actif, la r\u00e9sine \u00e9changeuse de cations et le chlorure mixte de terres rares. Toutefois, les m\u00e9thodes susmentionn\u00e9es comportent de nombreuses \u00e9tapes de post-traitement, qui ne sont pas faciles \u00e0 contr\u00f4ler, et le processus de pr\u00e9paration du catalyseur est compliqu\u00e9, ce qui n'est pas propice \u00e0 l'application et \u00e0 la promotion.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">A confirmer Utilisation<\/h2>\r\n\r\n\r\n\r\n<p>Ce produit est soluble dans la plupart des solvants organiques.

Par cons\u00e9quent, il peut \u00eatre utilis\u00e9 dans la production d'emballages alimentaires et de produits m\u00e9dicaux et sanitaires dans divers pays du monde, ainsi que dans les jouets pour enfants, les produits pharmaceutiques, les produits m\u00e9dicaux, les ar\u00f4mes et les parfums. Il est \u00e9galement utilis\u00e9 dans la fabrication de jouets souples pour enfants, de produits pharmaceutiques, de produits m\u00e9dicaux, d'ar\u00f4mes et de parfums.<\/p>\r\n\r\n\r\n\r\n<p>Le TBC peut conf\u00e9rer aux produits une bonne r\u00e9sistance au froid, \u00e0 l'eau et \u00e0 la moisissure. La r\u00e9sine pr\u00e9sente une bonne transparence et des performances de flexion \u00e0 basse temp\u00e9rature apr\u00e8s avoir \u00e9t\u00e9 plastifi\u00e9e avec ce produit. Elle pr\u00e9sente une faible volatilit\u00e9 et une faible extractibilit\u00e9 dans diff\u00e9rents milieux, une bonne stabilit\u00e9 thermique et ne change pas de couleur lorsqu'elle est expos\u00e9e \u00e0 la chaleur. L'huile lubrifiante fabriqu\u00e9e avec le TBC poss\u00e8de de bonnes propri\u00e9t\u00e9s lubrifiantes.<\/p>\r\n\r\n\r\n\r\n<p>Ces derni\u00e8res ann\u00e9es, les principaux plastifiants souvent utilis\u00e9s dans l'industrie sont les plastifiants phtalates. Comme les plastifiants \u00e0 base de phtalates peuvent induire une carcinogen\u00e8se, les pays \u00e9trangers ont strictement contr\u00f4l\u00e9 leur utilisation, et mon pays a \u00e9galement formul\u00e9 des lois et des r\u00e8glements pertinents qui supprimeront progressivement leur utilisation dans les mat\u00e9riaux d'emballage des produits alimentaires, les \u00e9quipements m\u00e9dicaux et les jouets. Le citrate de tributyle (TBC) est un nouveau type de plastifiant plastique non toxique. Il a suscit\u00e9 une grande attention en raison de sa bonne compatibilit\u00e9, de sa grande efficacit\u00e9 de plastification, de sa non-toxicit\u00e9, de sa non-volatilit\u00e9 et de sa forte r\u00e9sistance aux intemp\u00e9ries. Il est devenu le premier choix pour remplacer l'o-benz\u00e8ne. Produits \u00e9cologiques de protection de l'environnement \u00e0 base de diformate.<\/p>\r\n\r\n\r\n\r\n<p>Avec la sensibilisation accrue de la population \u00e0 la protection de l'environnement et l'am\u00e9lioration des lois et r\u00e8glements en la mati\u00e8re, le d\u00e9veloppement et la production de citrate de tributyle ont d'excellentes perspectives de d\u00e9veloppement.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><strong>Plastifiants ignifuges de la m\u00eame s\u00e9rie<\/strong><\/h2>\r\n<table style=\"border-collapse: collapse;
