我国紙漿年产一百多万吨,生产每吨紙漿的废液約有8立方米,其中木質素的含量約有半吨,即每年有数十万吨的木质素生成。此外,水解木材工業也有大量副产木质素。目前,世界各国不但不能很好地利用木质素,而且作廢料处理也有困难,如將废液放入河中,对漁业等是有害的。如果能把这样大量的废物用作有机合成的原枓,其重要性將可能与煤焦油相比。而且煤在地壳中储量一定,愈用愈少,而木質素則来自不断生長的植物,用之不尽。现在工业上由木質素制得的产率最高的單一的化合物是香草(?),它可以作香料或用于制防腐剂、医药等,但需要量都不大,远不能解决木質素的利用問題。高分子工業需要大量有机原料,如从木質素能合成性能优良的高分子,则对木質素的利用会有很大意
China’s pulp annual output of more than one million tons, the production of waste per ton of pulp about 8 cubic meters, of which about half a ton of lignin, that is, each year hundreds of thousands of tons of lignin formation. In addition, the hydrolyzed timber industry also has a significant amount of by-product lignin. At present, not only countries in the world are not able to make good use of lignin, they also have difficulties in handling waste materials. For example, putting waste into the river can be detrimental to fisheries. If such a large amount of waste can be used as a raw material for organic synthesis, its importance will probably be compared to that of coal tar. And coal reserves in the crust of a certain, less and less, and lignin from growing plants, inexhaustible. Now the lignin-producing single compound is vanilla (?), Which can be used as a preservative, medicine, etc., but its dosage is not large enough to solve the problem of lignin problem. The polymer industry requires a large amount of organic raw materials, such as high-performance polymer from lignin, the use of lignin will have great meaning
