Quantitative characterization of acetylation degree of phenolic hydroxyl compounds synthesized from thermally induced liquid crystal polymers (TLCP) using nuclear magnetic hydrogen spectroscopy
This study focuses on the acetylation process of two phenolic hydroxyl monomers, PHBA and BP. The composition of the acetylation products was analyzed by nuclear magnetic resonance hydrogen spectroscopy, and the effects of catalyst type, dosage, acetylation time, and acylation agent dosage on the degree of acetylation and product composition were explored. This provides a theoretical basis for optimizing the synthesis process of TLCP.
