METHOD FOR PRODUCING MANNICH ADDUCTS THAT CONTAIN POLYISOBUTYLENE PHENOL

摘要

POLYISOBUTENYLPHENOL-CONTAINING MANNICH ADDUCTS ARE PREPARED BY A) ALKYLATION OF A PHENOL WITH HIGHLY REACTIVE POLYISOBUTENE HAVING A NUMBER AVERAGE MOLESULAR WEIGHT OF LESS THAN 1000 AND A POLYDISPERSITY OF LESS THAN 3.0,AT BELOW ABOUT 50ºC IN THE PRESENCE OF AN ALKYLATION CATALYST; B) REACTION OF THE REACTION PRODUCT FROM A) WITH B1) AN ALDEHYDE CHOSEN FROM FORMALDEHYDE,AN OLIGOMER AND A POLYMER OF FORMALDEHYDE AND B2) AT LEAST ONE AMINE WHICH HAS AT LEAST ONE PRIMARY OR ONE SECONDARY AMINO FUNCTION. AND ARE USED AS DETERGENT ADDITIVES IN FUEL AND LUBRICANT COMPOSITIONS,AND ADDITIVE CONCENTRATES,FUEL COMPOSITIONS AND LUBRICANT COMPOSITIONS CONTAIN THESE MANNICH ADDUCTS.
