摘要
本文论述以工业萘、硫酸、甲醛为原料，经磺化、水解、缩合等步骤合成了β－萘磺酸盐甲醛缩合物阴离子表面活性剂，并在混凝土工程中进行了应用试验研究，得出了一些重要结论，为该表面活性剂的工业化生产提供了依据。
Using technical naphthalene, sulfuric acid and formaldehyde as raw materials,the synthesis of this kind of surfactant is studied bv sulfonation,decomposition,water condensation and other steps. Also, the results of applied experiments are reviewed in concrete engineering,some important conclusions given are very valuable to industrial-scale production of this surfactant.
