Storage method

This product should be sealed and stored in a cool place.

Synthesis method

It is obtained by chlorination of sodium parasulfamoylbenzoate. First, dissolve parasulfamoylbenzoic acid in sodium hydroxide solution to prepare 25% sodium parasulfamoylbenzoate solution. Place this solution into a chlorination pot and add sodium hydroxide solution. in5Pour in chlorine gas below ℃ to pH7-8, take the reaction solution and test the end point (the reaction solution is filtered and acid is added, and no precipitation is the end point). After reaching the end point, stop passing chlorine, stir 15min, and filter. Wash the filter cake with water, spin dry, and place in 40℃ or below. Crush and sift it to get the Hara Zong. The yield is 85%.

Purpose

This product is a disinfectant and antiseptic used for drinking water disinfection. At a concentration of 1/200,000 to 1/500,000, it can kill within 0.5~1 hours Kill Escherichia coli, typhoid bacilli, paratyphoid bacilli, cholera bacilli and Shigella dysentery bacilli, etc.
