木质素磺酸盐是以木材为原料酸法制浆造纸工业的副产物,广泛用作分散剂、粘合剂等。由于它是以苯丙烷为结构单元的水溶性高分子化合物,其分子量的测定有Sephadex凝胶法和用BioGel P、TSK PW、Waters Ⅰ系列、Waters μPorasil等柱
Lignosulphonate is a by-product of the acid pulping industry using wood as a raw material and is widely used as dispersant, adhesive and the like. Since it is a water-soluble polymer based on phenylpropane, its molecular weight is determined by the Sephadex gel method and columned with BioGel P, TSK PW, Waters Ⅰ Series, Waters μPorasil
