trisodium naphthalene-1,3,6-trisulphonate - Preparation method

Open Data Verified Data

Firstly, a sulfonation reaction occurs between refined naphthalene and oleic acid to obtain 1,3,6 naphthalene trisulfonic acid. After diluting the product, lime is added to neutralize excess sulfuric acid and react with naphthalene trisulfonic acid to obtain calcium salt of naphthalene trisulfonic acid. After the calcium salt is filtered and washed, pure alkali is added to the filter cake to react with it to obtain the sodium salt of naphthalene trisulfonic acid. Filter, wash, and dry the reaction products to obtain the finished product.
