    Abstract: A method for producing Mannich adducts that contain polyisobutenylphenol by: a) alkylating a phenol with highly-reactive polyisobutylene having more than 70 mol% of vinylidene double bonds and a number average molecular weight between 300 to 3000 at a temperature lower than approximately 50 °C and in the presence of an alkylation catalyst; b) reacting the reaction product from a) with formaldehyde, an oligomer or with a polymer of the formaldehyde and with at least one amine, which has at least one secondary amino function and does not have any primary amino function; or c) reacting the reaction product from a) with at least one adduct consisting of at least one amine, which has at least one secondary or primary amino function, and with formaldehyde, an oligomer of the formaldehyde, a polymer of the formaldehyde or with a formaldehyde equivalent is disclosed. These Mannich adducts that can be obtained by using this method are used as detergent additives in fuel compositions and lubricant compositions, and to additive concentrates, fuel compositions and lubricant compositions containing these Mannich adducts.

    Abstract: Polyisobutenylphenol-containing Mannich adducts are prepared by a) alkylation of a phenol with highly reactive polyisobutene at below about 50° C. in the presence of an alkylation catalyst; b) reaction of the reaction product from a) with formaldehyde, an oligomer or a polymer of formaldehyde and at least one amine which has at least one secondary amino function and no primary amino function, or c) reaction of the reaction product from a) with at least one adduct of at least one amine which has at least one secondary or primary amino function and formaldehyde, an oligomer of formaldehyde, a polymer of formaldehyde or a formaldehyde equivalent, and are used as detergent additives in fuel and lubricant compositions, and additive concentrates, fuel compositions and lubricant compositions contain these Mannich adducts.
