摘要

Monoamide-containing polyether alcohol compounds of formula (I), wherein R1, R2, and R3 are each independently selected from hydrogen, hydrocarbyl of 1 to 100 carbon atoms, susbtituted hydrocarbyl of 1 to 100 carbon atoms and polyoxyalkylene alcohol of 2 to 200 carbon atoms or R2 and R3 taken together form a heterocyclic group of 2 to 100 carbon atoms or a substituted heterocyclic group of 2 to 100 carbon atoms with the proviso that at least one of R1, R2 or R3 must be polyoxyalkylene alcohol, have been found to decrease intake valve deposits, control octane requirement increases and reduce octane requirement when used as gasoline additives.
