Information

Polyisobutenyl succinic anhydride is a chemical intermediate obtained by the reaction of polyisobutene and maleic anhydride.

Polyisobutylene Succinic Anhydride For sale

The high-activity polyisobutene is heated to a certain temperature, and then replaced with nitrogen for protection; under a certain temperature condition, the polyisobutene is reacted with maleic anhydride in a certain proportion, and when the conversion rate of the terminal olefin is greater than a certain proportion, the remaining amount is added. maleic anhydride, so that the final molar ratio of polyisobutylene to maleic anhydride reaches a value within a range; increase the temperature and continue the reaction. When the conversion rate of terminal alkene is greater than 95%, the temperature will continue to be raised to 230-250 °C, and the reaction will continue until the degree of substitution of maleic anhydride on the polyisobutylene is greater than 1.2; acid anhydride to obtain transparent polyisobutylene succinic anhydride without coking.
