STRAIGHT CHAIN POLYALKENYL SUCCINIMIDE

PROCESS FOR THE PREPARATION OF A POLYALCENYL-SUCCINIC ANHYDRIDE, PRODUCT THUS PREPARED AND LUBRICATING OIL COMPOSITION CONTAINING THE PRODUCT

La préparation de PIB/MALA avec des rendements élevés (plus de 90 %) par réaction de polyisobutène PIB avec l'anhydride maléique MALA en présence de chlore a l'inconvénient d'entraîner la présence d'un pourcentage relativement élevé de chlore (environ 6 % en poids) dans le produit PIB/MALA. Une réaction ultérieure sans addition de chlore (en présence de MALA en excès) donne, après que le MALA a été chassé par strippage, un produit ayant une teneur en chlore d'environ 0,4 % en poids. Ce pourcentage peut maintenant être réduit à moins de 0,2 % en poids quand on soumet le produit PIB/MALA à un traitement thermique à 200 degrés C environ après que le MALA en excès a été chassé par strippage. Les produits selon la présente invention sont particulièrement utilisables pour la préparation de dispersants sans cendre pour huiles, telles que des huiles lubrifiantes. The preparation of PIB / MALA with high yields (more than 90%) by reaction of polyisobutene PIB with maleic anhydride MALA in the presence of chlorine has the drawback of causing the presence of a relatively high percentage of chlorine (approximately 6% by weight) in the GDP / MALA product. A subsequent reaction without addition of chlorine (in the presence of excess MALA) gives, after MALA has been stripped off, a product having a chlorine content of approximately 0.4% by weight. This percentage can now be reduced to less than 0.2% by weight when the PIB / MALA product is subjected to a heat treatment at approximately 200 degrees C after the excess MALA has been stripped off. The products according to the present invention are particularly usable for the preparation of ashless dispersants for oils, such as lubricating oils.
