Precautions
Health Hazards
Irritating. In industrial use, contact may cause eczema.
Flammability Hazard
This product is flammable and irritating.
Hazardous Characteristics
Powder and air can form explosive mixtures. In case of open flame, high heat or contact with oxidizing agent, there is a danger of combustion and explosion. Citric acid monohydrate and sodium citrate dihydrate are paired with citrate buffer of pH 6.0.
Since the pH is 6, the buffer pair is disodium salt and trisodium salt (citric acid Ka1 = 7.4 × 10-4, Ka2 = 1.7 × 10-5, Ka3 = 4.0 × 10-7)
Storage of Citric Acid Monohydrate
Store away from light, sealed, ventilated, at low room temperature, in a dry and cool place.

Company information

The company's main import and export products include

(1)Water Treatment:Physical methods also include precipitation, is to let the impurities of smaller specific gravity float on the surface of the water to fish out, or the impurities of larger specific gravity precipitation in the lower, and then obtain. Chemical method is to use a variety of chemicals in the water impurities into less harmful substances, or impurities concentrated, the longest history of chemical treatment methods should be considered to be added to the water with alum, the collection of impurities in the water, the volume becomes larger, it can be used for filtration, the removal of impurities.

(2)Organic Raw Materials are widely used and can be divided into three aspects: one is the raw material used to produce polymer chemical products, that is, the monomer for polymerization; the other is used in other organic chemical industries, including raw materials for fine chemical products; Used in solvents, refrigerants, antifreezes, gas adsorbents, etc. Basic organic chemicals are the basis for the development of various organic chemical products and are a major component of modern industrial structures.
