1.Propri\u00e9t\u00e9 du produit<\/h4>\n

L'ac\u00e9tate d'\u00e9thyle, \u00e9galement connu sous le nom d'ester \u00e9thylique de l'acide ac\u00e9tique, est un compos\u00e9 organique dont la formule chimique est C4<\/sub>H8<\/sub>O2<\/sub>. Il s'agit d'un type d'ester (avec un groupe fonctionnel -COOR, o\u00f9 le carbone et l'oxyg\u00e8ne forment une double liaison) qui peut subir les r\u00e9actions courantes des esters telles que l'alcoolyse, l'hydrolyse des amides, l'\u00e9change d'esters et la r\u00e9duction. Il est principalement utilis\u00e9 comme solvant, comme agent aromatique alimentaire et comme d\u00e9shuileur.<\/p>\n

3. Champ d'application et utilisation<\/h4>\n

L'ac\u00e9tate d'\u00e9thyle est l'un des esters d'acide gras les plus utilis\u00e9s. C'est un solvant \u00e0 s\u00e9chage rapide qui pr\u00e9sente une excellente solubilit\u00e9 et constitue un excellent solvant industriel. Il peut \u00e9galement \u00eatre utilis\u00e9 comme \u00e9luant dans la chromatographie sur colonne. Il peut \u00eatre utilis\u00e9 pour la nitrocellulose, l'\u00e9thylcellulose, le caoutchouc chlor\u00e9 et les r\u00e9sines vinyliques, les esters d'ac\u00e9tate de cellulose, l'ac\u00e9tate de cellulose et de butyle et le caoutchouc synth\u00e9tique. Il peut \u00e9galement \u00eatre utilis\u00e9 comme encre liquide nitrocellulosique pour les photocopieurs. Il peut \u00eatre utilis\u00e9 comme solvant pour les adh\u00e9sifs et comme diluant pour la peinture. L'ac\u00e9tate d'\u00e9thyle est un solvant tr\u00e8s efficace pour de nombreux types de r\u00e9sines et est largement utilis\u00e9 dans la production d'encre et la fabrication de cuir artificiel. Il est utilis\u00e9 comme r\u00e9actif analytique, comme substance standard pour l'analyse chromatographique et comme solvant.<\/p>\n

4. l'emballage et le stockage<\/h4>\n

Qualit\u00e9 alimentaire : g\u00e9n\u00e9ralement emball\u00e9 dans des conteneurs scell\u00e9s de 25 kilogrammes par sac ou de 20 kilogrammes par tonneau, avec une dur\u00e9e de conservation de 720 jours (deux ans).<\/p>\n

Qualit\u00e9 industrielle : Les conditionnements courants sont les suivants : 500 ml, 2 500 ml et 20 kg\/baril, avec une dur\u00e9e de conservation g\u00e9n\u00e9rale de 12 mois (un an).<\/p>\n

Stockage herm\u00e9tique : La dur\u00e9e de conservation est g\u00e9n\u00e9ralement plus longue lorsque le produit est stock\u00e9 de mani\u00e8re herm\u00e9tique, mais il faut \u00e9viter les temp\u00e9ratures \u00e9lev\u00e9es ou l'exposition \u00e0 l'air.<\/p>\n

Apr\u00e8s ouverture : Si le produit n'est pas scell\u00e9 ou s'il est expos\u00e9 fr\u00e9quemment \u00e0 l'air, les ingr\u00e9dients actifs peuvent diminuer en raison de l'\u00e9vaporation. Il est recommand\u00e9 de l'utiliser d\u00e8s que possible apr\u00e8s ouverture.<\/p>","protected":false},"excerpt":{"rendered":"
