摘要
介绍了用工业萘、硫酸、甲醛为原料 ,合成高聚合度 β—萘磺酸盐甲醛缩合物的工艺过程。试验了不同的萘与甲醛配比、反应时间和催化剂对缩合物核体数的影响 ,确定了可行的工艺条件。
The synthetic process of producing high-polymeric β -naphthalenesulfonic acid-formaldehyde condensate is introduced in this paper.Different matching proportion of naphthalene with formaldehyde,various reaction time and catalysts were tested to show the effect on the nucleosome number of condensate.Results of the test establish the feasible technical conditions.
