Product name:Sodium pyrophosphate decahydrate
CAS:13472-36-1
Molecular Formula:H20Na4O17P2
Formula Weight:446.06
Specification:500g
Description:Sodium pyrophosphate decahydrates are colorless monoclinic crystals or white crystals or white crystalline powders. Relative density 1.824. Melting point is 880 ℃. Soluble in water, insoluble in alcohol. Its aqueous solution is alkaline (the Ph value of 1% aqueous solution is 10 ~ 10.2) and easy to weather in dry air. The water of crystallization is lost when heated to 100℃. An aqueous solution heated to disodium hydrogen phosphate. It has strong Ph buffering, and can chelate metal ions. It has hygroscopicity and needs to be sealed for storage.
Sodium pyrophosphates decahydrates can be used as hydrates, boiler desilters and metal ion chelates. Dispersant, printing and dyeing and fine bleaching AIDS. An additive to a synthetic detergent. Oil well mud regulator. Sodium pyrophosphate decahydrates were also used as complexing agents for copper in plating solutions.
