采用以多元羧酸为酯化剂，以无机盐类和含氮化合物为催化剂的交联体系。这是一类新型的、水溶性的、无毒害、无污染的非甲醛系试剂交联体系。用ＦＴＩＲ红外光谱定量解析了反应温度对多元羧酸与纤维素、木质素和木粉交联酯化产物的反应参数（增重率、酯化度、羰基比和交联度）的影响，结果表明：提高反应温度，酯化度、羰基比和交联度增加，过高的温度使酯化度增加较多，而交联度增加较少。为了减少交联反应过程中木材组分的化学降解，增大交联度，适宜的反应温度约为１６０℃。
The use of polycarboxylic acid as the esterification agent, inorganic salts and nitrogen compounds as a catalyst for the crosslinking system. This is a new class of water-soluble, non-toxic, non-polluting non-formaldehyde reagent crosslinking system. The effects of reaction temperature on the reaction parameters (weight gain rate, esterification degree, carbonyl ratio and cross-linking degree) of polycarboxylic acid with cellulose, lignin and wood flour were quantitatively analyzed by FTIR spectroscopy. The results The results showed that: increasing the reaction temperature, the degree of esterification, the carbonyl ratio and the degree of crosslinking increased, while the high temperature increased the degree of esterification more, while the degree of crosslinking increased less. In order to reduce the chemical degradation of the wood components during the crosslinking reaction and increase the degree of crosslinking, a suitable reaction temperature is about 160 ° C.
