Le N,N-di\u00e9thylformamide est un bon solvant pour une vari\u00e9t\u00e9 de polym\u00e8res tels que le poly\u00e9thyl\u00e8ne, le chlorure de polyvinyle, le polyacrylonitrile, le polyamide, etc., et peut \u00eatre utilis\u00e9 pour la filature humide de fibres synth\u00e9tiques telles que les fibres de polyacrylonitrile et la synth\u00e8se de polyur\u00e9thane ; il est utilis\u00e9 dans la fabrication de films plastiques ; il est \u00e9galement utilis\u00e9 comme d\u00e9capant pour enlever la peinture ; il peut \u00e9galement dissoudre certains pigments faiblement solubles, donnant aux pigments les caract\u00e9ristiques des colorants. Le dim\u00e9thylformamide est utilis\u00e9 pour l'extraction aromatique, la s\u00e9paration et la r\u00e9cup\u00e9ration du butadi\u00e8ne de la fraction C4 et de l'isopr\u00e8ne de la fraction C5. Il peut \u00e9galement \u00eatre utilis\u00e9 comme r\u00e9actif efficace pour s\u00e9parer les composants non hydrocarbon\u00e9s de la paraffine. .<\/h4>\n<h4>2. Il pr\u00e9sente une bonne s\u00e9lectivit\u00e9 pour la solubilit\u00e9 de l'acide isophtalique et de l'acide t\u00e9r\u00e9phtalique : la solubilit\u00e9 de l'acide isophtalique dans le N,N-di\u00e9thylformamide est sup\u00e9rieure \u00e0 celle de l'acide t\u00e9r\u00e9phtalique, et il est utilis\u00e9 pour l'extraction par solvant dans le formamide de l'acide dicarboxylique ou une partie de la cristallisation peut s\u00e9parer les deux. Dans l'industrie p\u00e9trochimique, le N,N-di\u00e9thylformamide peut \u00eatre utilis\u00e9 comme absorbant de gaz pour s\u00e9parer et raffiner le gaz.<\/h4>\n<h4>3. Dans les r\u00e9actions organiques, le N,N-di\u00e9thylformamide est non seulement largement utilis\u00e9 comme solvant pour la r\u00e9action, mais aussi comme interm\u00e9diaire important dans la synth\u00e8se organique. Il peut \u00eatre utilis\u00e9 pour produire des insecticides dans l'industrie des pesticides.<\/h4>\n<h4>4. R\u00e9actifs pour titrage non aqueux, solvants pour r\u00e9sine vinylique et ac\u00e9tyl\u00e8ne, synth\u00e8se organique, d\u00e9termination photom\u00e9trique, liquide stationnaire de chromatographie en phase gazeuse (temp\u00e9rature maximale d'utilisation 50\u2103, le solvant est le m\u00e9thanol), s\u00e9paration et analyse des hydrocarbures C2-C5, et peut s\u00e9parer le normal et l'isobutyl\u00e8ne et le cis, but\u00e8ne. Analyse des r\u00e9sidus de pesticides. Synth\u00e8se organique. Synth\u00e8se de peptides. Pour l'industrie photographique.<\/h4>\n<h4>5. Il s'agit d'un excellent solvant et d'une mati\u00e8re premi\u00e8re chimique dont les utilisations sont tr\u00e8s vari\u00e9es. C'est un excellent solvant pour de nombreux polym\u00e8res tels que le poly\u00e9thyl\u00e8ne, le chlorure de polyvinyle, le polyacrylonitrile, le polyamide, etc. Il peut \u00eatre utilis\u00e9 pour la filature humide de fibres synth\u00e9tiques telles que les fibres de polyacrylonitrile, la synth\u00e8se de polyur\u00e9thane, le d\u00e9capage de peinture, l'absorption s\u00e9lective de l'ac\u00e9tyl\u00e8ne et la s\u00e9paration et le raffinage du butadi\u00e8ne, utilis\u00e9 comme solvant dans la production de cuir artificiel, utilis\u00e9 pour synth\u00e9tiser des insecticides ; dans l'industrie pharmaceutique, il peut \u00eatre utilis\u00e9 pour synth\u00e9tiser l'iodosamine, la doxycycline, la cortisone, la vitamine B6, l'iodoside, le ququjing, le pyrantel, la N-formyllysine et l'acide antitumoral, le m\u00e9thoxychlore, le chlorambucil, la nitrosour\u00e9e, le furfurouracil, l'acide tranexamique, la b\u00e9fenm\u00e9thasone, le m\u00e9gestrol, la cholyvitamine, la chlorph\u00e9niramine, etc.<\/h4>\n<h4>6. Utilis\u00e9 comme solvant et modificateur organique en chromatographie liquide, comme extractant et agent de d\u00e9veloppement pour la chromatographie sur couche mince, comme solvant pour la r\u00e9sine de vinyle et l'ac\u00e9tyl\u00e8ne, et comme solvant pour le titrage de solvants non aqueux. Utilis\u00e9 \u00e9galement dans la synth\u00e8se organique.<\/h4>\n<h4>7. Principalement utilis\u00e9 comme solvant industriel, dans l'industrie pharmaceutique pour la production d'hormones et \u00e9galement pour la fabrication d'insecticides.<\/h4>\n<p>&nbsp;<\/p>\n<h2><strong>Emballage et exp\u00e9dition du N,N-Di\u00e9thylformamide<\/strong><\/h2>\n<h4>Emballage : 180kg\/tambour<\/h4>\n<p>&nbsp;<\/p>\n<h2><strong>N,N-Di\u00e9thylformamide Stockage<\/strong><\/h2>\n<h4>Stockage scell\u00e9, ne pas mettre les produits en contact avec des produits chimiques alimentaires.<\/h4>\n<p>&nbsp;<\/p>\n<h2><strong><b>Contactez-nous d\u00e8s maintenant !<\/b><\/strong><\/h2>\n<h4><strong><b>Nous fournissons des services personnalis\u00e9s, nous vous contacterons g\u00e9n\u00e9ralement dans les 24 heures.
