Physical and Chemical Properties
Sulfamic acid is a moderately strong acid, Ka = 0.101 (pKa = 0.995). Because the solid is not hygroscopic, it is used as a standard in acidimetry (quantitative assays of acid content).Double deprotonation can be effected in liquid ammonia to give the anion
Application
a.Sulfamic acid is used as an acidic cleaning agent and descaling agent sometimes pure or as a component of proprietary mixtures, typically for metals and ceramics.
b.It also finds applications in the industrial cleaning of dairy and brewhouse equipment. Although it is considered less corrosive than hydrochloric acid, corrosion inhibitors are often added to the commercial cleansers of which it is a component. It can be used as a descalant for descaling home coffee and espresso machines and in denture cleaners.
C.Catalyst for esterification process
d.Dye and pigment manufacturing
e.Herbicide, as ammonium sulfamate
F.escalant for scale removal
g.Coagulator for urea-formaldehyde resins
f.Ingredient in fire extinguishing media. Sulfamic acid is the main raw material for ammonium sulfamate which is a widely used herbicide and fire retardant material for household products.
I.Pulp and paper industry as a chloride stabilizer
Storage
The storage warehouse should be kept dry, well ventilated, away from fire and heat sources, and protected from direct sunlight. Sulfamic acid should be stored separately from oxidising agents, alkalis, etc. and should never be mixed.
