A method of processing wood oil which is generated during pulping. In the method, low molecular weight carboxyl acid that is approximately 0.5-5.0% of the wood oil quantity (weight) is added to that wood oil early in its separation stage, in order to esterify the alcohol groups present in the wood oil, by the said acid. The protective esterification according to the present invention prevents the esterification of the alcohol groups by the fatty acids naturally present in the wood oil.
在制浆过程中生成的木油的处理方法。该方法中,在木油分离阶段的早期向木油中添加约占木油数量(重量)0.5-5.0%的低分子量羧酸,以便通过所述酸酯化木油中存在的醇基。根据本发明的保护酯化可以防止木油中天然存在的脂肪酸对醇基的酯化。
