摘要：

本研究采用以多元羧酸类化合物为酯化剂,以无机盐为催化剂的交联体系。这一体系是新型的、水溶的、无毒害、无污染、木材交联反应未采用过的非甲醛系试剂交联体系。本文采用FTIR和CP/MAS ¹³CNMR的光谱法确定了多元羧酸类化合物与木材交联反应产物的形成特征和交联反应参数。

Abstract:

Polycarboxylic acids and inorganic salts are used as esterification agents and catalyst, respectively, in our research on wood crosslinking reaction. This new crosslinking system is composed of the reagents of non-formaldehyde series and it is soluble, poison-free and pollution-free.The characteristics and parameters (esterification degree, carbonyl ratio and crosslinkage degree) of esterification between wood and polycarboxyic were determined by FTIR ¹³CNMR spectra in this paper.

Key words: Polycarboxylc acids, Crosslinking reaction, Esterification degree, Carbonyl ratio, Crosslinkage degree
