◆ Sodium Citrate
Sodium citrate was first produced in1987, and it is the earliest
formed scale factory. It was researched, designed by the factory itself;
it was the sole patent products in line trade, and approved by the
State Patent Bureau. With an advanced production technology, steady
quality, and it has an annual production capacity of 10000 tons.

Package: Package: 25kg/ Plastic bag in knitting sack or 1000kg/Plastic
bag in knitting sack Or 25kg complex kraft paper bag.
Properties: White crystal or crystalline powder and ease to be effloresced.
Its crystal water is total lost on 150 . It resolves when temperature
is too high. It dissolves in water, but not in alcohol.
Application:
Used as anticoagulant, chemical reagent, food additive, developer,
buffer emulsifying agent, stabilizing agent and used in nonhydrogen
electroplating as well as widely in tail gas absorption process
of sulfur dioxide for chemical and metallurgy industries. Its absorptivity
reaches 99%. The waste absorbed may be regenerated into sulfur dioxide
liquid and potassium citrate for cyclic utilization. The daily-use
chemical detergent with potassium citrate. As raw material instead
of sodium phosphate trimmer, it is non-toxic and non-pollution.
It also may be used as buffer agent in cosmetic production.
Quality:
For industry use---Xiang Standard Q/CHSG40-87, Assay 96-98%.For
foodstuffs---GB (Chinese Standard), Assay>99%For export---BP
