Sulfamic acid
name：Sulfamic acid
Formula：NH2SO3H
M.W：97.09
CAS NO.：5329-14-6s
Characters：Sulfamic acid is extremely when the room temperature stability of the pure white crystals, odourless, non-volatile, moisture absorption, when the room temperature is stable, performance remains unchanged for many years, all of the common salt (except calcium, barium and lead salt) are soluble in water, slightly soluble in organic solvents.The aqueous solution of aminosulfonic acid is a highly ionized substance, whose PH value is lower than that of formic acid, phosphoric acid and oxalic acid.Melting point: 205 ℃ and decomposition temperature: 209 ℃, specific gravity: 2.126.
Usage：Main raw materials of potassium acetylsulfonate;It is widely used as a cleaner for herbicides, fireproofing agents, metals and ceramics.Softener and bleaching agent for paper and textiles;Synthesis of urea formaldehyde resin catalyst;In the production of azo dyes;A stabilizer for chlorination and bleaching in the swimming pool;As the base reagent for acid and alkali titration in analytical chemistry;Used for a wide range of acidic cleaning agents, cleaning Wells and increasing oil production;Electroplating;Etching;Electrochemical polishing;Bitumen emulsification, etc.
