PREPARATION OF N-(1-ALKOXYALKYL) FORMAMIDE AND BIS FORMAMIDES

摘要

This invention relates to an improved process for the formation of N-(1-alkoxyalkyl)amides with coproduction of alkylidene bisamides. The N-(1-alkoxyalkyl)formamides of this invention are prepared by reacting formamide with an acetal or hemiacetal carboxylate ester represented by the formulas: I II wherein R is C1-C8 alkyl, aralkyl or aryl; R1 and R2 are C1-C8 alkyl, or aryl; and R3 is secondary or tertiary alkyl having from 3-8 carbon atoms. The reaction is carried out in the presence of an acid catalyst such as a strong acid ion exchange resin.
