摘　　要：利用脂肪酶联合过氧乙酸、H2O2、1,4-二氧六环3种氧化剂对马尾松TMP进行处理,用紫外分光光度法测定其甘油三酸酯含量,用红外光谱分析树脂成分的变化。结果表明,脂肪酶结合化学法处理后,马尾松TMP中甘油三酸酯的降解率由脂肪酶处理后的21.1%提高到34.8%;上述3种氧化剂不仅可以降解树脂中的甘油三酸酯,且可以增加芳香族化合物与苯环相连接的烷烃中的羟基数量。The lipase combining with peroxyacetic acid, hydrogen peroxide and 1,4 - dioxane was utilized to treat the TMP of masson pine. The removal of resin was determined with ultraviolet spectrophotometric method. The results showed that the degradation rate of triglyceride from 21.1% after the treatment of lipase increases to 34.8 % by the lipase treatment combining with the chemicals. Therefore, it paves a new way for the pitch control of TMP in the mill.
