Reduction of the carboxylic acid functional groups in the cinnamic acids provides the corresponding aldehydes, such as cinnamaldehyde. Further reduction provides monolignols including coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol, which vary only in their degree of methoxylation. The monolignols are monomers that are polymerized to generate various forms of lignin and suberin, … Web摘要: The photopolymerization of acrylonitrile (AN) initiated with phenyl hydrazine (PHZ) and its derivatives has been studied. The initiator exponent and monomer exponent were determined from the kinetic investigation to be 0.66th and 2.1th respectively and the overall activation energy was 33.4KJ/mol for the PHZ-AN system.
