Use
1.Used in leather industry, as leather tanning ,catalyzer ,disifec-tor used as camouflage salt in the chrome tanning method
2.Use in catalyst and stabilizer compositions
3. Use in textile dyeing as a reducing agent.
4. Used in the raw material for manufacture of sodium hydrosul-phite,formic acid and oxalic acid
5. Used as anti-frosting agent in concrete
6. precipitate precious metal
7. As buffer action , adjusting the value of PHin strong acid
The main use is used as the leather industry, and the main purposes are as follows: (1) mainly used to produce methic acid, oxalic acid and insurance powder, and also used to produce di metamimam. It is also used for medicine, printing and dyeing industry. ; (2) For reagents, disinfection agents and media dyes for measuring arsenic;
(3) For preservatives. Uses 4: For alcoholic acid resin coatings, plasticizers, and martyrs; (4) use as explosives, acid -resistant materials, aviation lubricating oil, and adhesive additives. Sodium sodium manufacturing method (1) The carbon monoxide and sodium hydroxide solution reacts to form sodium methampate under the pressure of 160 ~ 200 ° C and 2MPa, and then obtains the sulfuric acid hydrogenate and distillation. The main response equations are: Co + NaOH → HCOONA2HCOONA + H2SO4 → 2hCooh + Na2SO4 (2) A by -product of manufacturing new pentoplastol, precursor tetopenol, and trifonacre propylene.
