Product Description

sodium citrate dihydrate CAS no 6132-04-3

Production methods

1. Neutralization of citric acid by sodium hydroxide or sodium bicarbonate. Will be dissolved in water, heated by sodium bicarbonate in mixing join citric acid, continue to heat up to 85-90 ℃, adjust pH value of 6.8. The activated charcoal is decolorized, while the filter is hot. The filtrate decompression and concentration, and the crystallization after cooling. Filtration, washing, drying, sodium citrate. Sodium bicarbonate stirring dissolved in hot water first, then, in 85 ~ 90 ℃, the citric acid neutralization to Ph 6.8. Add the activated charcoal to decolorize, and then filter. The filtrate is concentrated by decompression, cooling crystallization, centrifugation, washing and drying of sodium citrate. C6H8O7 + 3 nahco3 – write C6H5Na3O7 · 2 H2O + 3 co2 + H2O

2. The use of 70 ℃ drying of anhydrous citric acid and 160 ℃ drying of anhydrous sodium carbonate as raw material. Dissolve 1 mole of citric acid in 600mL water, and add a few small amounts of sodium carbonate, which is chemically metered, and keep stirring constantly. Boil the solution for 30min. Filter, collect the filtrate in the known weight of the evaporating dish, the water bath is concentrated to the precipitation crystal. Crystal by air drying, and then in the 70 ℃ drying.

3. Neutralization of citric acid by sodium hydroxide or sodium bicarbonate.

use

1. Mainly used as food additives, electroplating industrial complex agent, buffer, pharmaceutical industry for the manufacture of anticoagulant, light industry as detergent auxiliary, etc.;

2. Used for daily essence;

3. Used in food, beverage, medicine, chemical, washing and other industries, mainly used as acid regulator, flavoring agent, without any toxicity or corrosiveness.
