Phenolic-containing mannich base reaction products and fuel compositions containing same
This patent describes a product of reaction suitable for use as a liquid hydrocarbyl fuel additive made by reacting a performed Mannich base with a reactive compound selected from hydrocarbyl thiols having at least one reactive hydrogen, the reaction being carried out with an equivalent amount of Mannich Base, or with a molar ratio varying 1 to 1 to about 2 to 1 of Mannich Base to thiol at temperatures varying from about 25/sup 0/ to about 250/sup 0/C. the Mannich base having been prepared from (1) a phenol, (2) a C/sub 1/-C/sub 8/ alkyl aldehyde and (3) an amine having a lower boiling point than that of the reactive thiol, the phenol having the following generalized structural formula: where R/sup 2/ and R/sup 3/ are the same or different and are hydrogen or C/sub 1/ to about C/sub 18/ alkyl or tertiary alkyl and R/sup 4/ is H or C/sub 1/ to about C/sub 30/ hydrocarbyl.
