Filed: 1996-12-12
Abstract: Pour la préparation d'un d'anhydride d'alcényle succinique ou 'ASA' (pour 'alkenyl succinic anhydride') à partir d'un hydrocarbure insaturé au niveau de la fonction oléfine et d'un anhydride maléique, on utilise un mélange d'additifs lors de la réaction de préparation afin d'améliorer la qualité résultante du produit et de réduire les réactions secondaires. Selon la présente invention, un mélange entre, d'une part un composé aromatique contenant de l'azote ou du soufre, de préférence du benzothiazole ou l'un de ses dérivés, et d'autre part un antioxydant ou l'un de ses dérivés, présente de telles propriétés. Chaque additif est présent selon une proportion molaire d'approximativement 0,01 à 5 % de la quantité de l'anhydride maléique. L'oléfine est de préférence une α-oléfine à chaîne droite ou une oléfine à chaîne droite ou à chaîne à ramifications internes présentant une chaîne de carbone d'une longueur de 6 à 20 atomes de carbones. L'oléfine peut également être une polyoléfine, auquel cas la masse moléculaire préférée se situe entre 900 et 1500. La préparation peut se faire par lots ou partiellement par lots, l'anhydride maléique ainsi que l'additif pouvant être ajoutés en plusieurs lots en arrivée continue, régulière ou variable. L'anhydride d'alcényle succinique obtenu selon ce procédé peut convenir en particulier comme additif alimentaire, pour rendre le papier hydrophobe, ou comme agent dispersant dans les lubrifiants.
