| Introduction | p-hydroxybenzenesulfonic acid (4-hydroxybenzenesulfonic acid) is white crystalline powder, soluble in water, hot alcohol and glycerol. Sodium p-hydroxybenzenesulfonate is a very important intermediate in organic synthesis and pharmaceutical industry, and its research value and commercial value are gradually found. |
| Application | p-hydroxybenzenesulfonic acid is the most important additive in acid tin plating process, and also has the effect of acid resin foaming, used as casting resin curing agent at room temperature. |
| preparation | take 100g of mesitylene, add 78g of phenol to it, heat to 65 °c in a water bath, add 4g of phosphorous acid as a catalyst, add the raw material into the feed tank at one time, add 82g of concentrated sulfuric acid into the concentrated sulfuric acid feed tank, make n(H2SO4):n(C6H6O)= 1:1,n(C9H12):n(C6H6O)= 1:1. The temperature was increased to 100 °c. The stirrer and the high-gravity reactor were turned on, the rotor speed of the high-gravity reactor was adjusted, and the rotation speed of the high-gravity reactor 10 was maintained at 2000rpm. After the temperature and equipment were stabilized, the feed was started at a feed rate of 250ml/min, the feed was completed, and the circulation was 3min to obtain p-hydroxybenzenesulfonic acid. |
| Application | for resin curing is the most important additive in acid tin plating process, at the same time also has the role of acidic resin foaming used as casting resin curing agent at room temperature organic intermediates. |
