摘要
本研究采用以多元羧酸类化合物为酯化剂 ,以无机盐类和含氮化合物为催化剂的关联体系。这一体系是一类新型的、水溶性的、无毒害、无污染的非甲醛系试剂交联体系。本文采用FTIR光谱 ,测定了木材及主要组分在交联化处理过程中的化学结构变化 ;推测了多元羧酸与木材各组分的酯化过程经历酸酐反应中间体。
Polycarboxylic acids acted as esterification agents and inorganic salts acted as catalyst in the research of wood crosslinking reaction. This new and soluble crosslinking system is poison free and pollution free system. In this work crosslinking reaction intermediate was proofed by FTIR spectra, therefor we can infer crosslinking reactions between polycarboxylic acid and wood want through cyclic anhydride intermediates.
