|
Formula: NH2SO3H Mol. Wt: 97.09
Other Name : Aminosulfonic acid |
Description:
It is a white rhombus crystal or flake crystal , colorless , non-volatile
, non –hygroscopic. Relative density is (d 204) : 2.126 . Melting
point : 205 ℃ . Decompose at 209 ℃ , further decompose to sulfur dioxide
, sulfur trioxide , nitrogen and water under 260 ℃. Reflective index
(αtype): 1.553 ,(βtype): 1.563 and (γtype):1.568 . Soluble in water
and liquid ammonium , slightly soluble in methyl alcohol , insoluble
in ethyl alcohol and ethyl ester , insoluble in carbon disulfide and
liquid sulfur dioxide . Its solution in water has the similar acidity
characteristics with sulfur acid and sulfur acid and sulfate acid
, its salts series therefore insoluble in water . |
Functional use:
It is used as criterion reagent in analytical chemicals; as herbicides
and anti-flammable agents ; as softener and bleaching agent in and
paper & textile products ; as cleaner agent in metal and porcelain
; catalyst in synthetic urea formaldehyde resin ; as anti-cyanide
agent in azo dye production ; as stabilizer in chlorinated liquid
and bleaching liquid used for swimming pool . |
