Calcium Sulfate Dihydrate is the raw material for manufacturing cement, calcium sulfate hemihydrate and sulfuric acid. Used as a filler in the paint and paper industry. As a chemical fertilizer in agriculture, it can reduce soil alkalinity and improve soil performance. Edible grade can be used as nutritional supplement (calcium fortification), coagulant, yeast feed, dough regulator and chelator. It can also be used as tissue enhancer in canned tomatoes and potatoes, hardener of brewing water, flavor enhancer of wine, etc.

Acetyl n-propanol is a chemical substance. It is a colorless and transparent liquid. Soluble in water, ethanol and ether. purpose ：Pharmaceutical intermediate, mainly used for antimalarial chloroquine phosphate. It can also be used to produce vitamin B1, etc.

Acetylacetone is a colorless to light yellow transparent liquid, which is usually a mixture of enol and keto tautomers. The two tautomers are in dynamic equilibrium, with keto form accounting for about 18% and enol form accounting for 82%. Acetylacetone is soluble in water, ethanol, benzene, chloroform, ether, acetone, ethyl acetate and glacial acetic acid. Acetylacetone is an important intermediate in organic synthesis, which is widely used in pharmaceutical, perfume, pesticide and other industries. Acetylacetone is an important raw material in pharmaceutical industry, such as the synthesis of 4,6-dimethylpyrimidine derivatives. Acetylacetone is also used as a solvent for cellulose acetate, a desiccant for paints and varnishes, an additive for fuel oil and lubricating oil, a catalyst, a resin crosslinker, a resin curing accelerator, and an important organic solvent and analytical reagent. Acetylacetone can chelate with cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminum, chromium, iron (Ⅱ), copper and other metal ions due to the presence of enol. Acetylacetone can be used as a metal cleaning agent in micropores by its chelation with metal.

This product has the characteristics of high efficiency, broad spectrum, safety and long residual period. It is an excellent insecticide and acaricide. It has high activity in controlling Lepidoptera pests, mites, Coleoptera and Homoptera pests such as cotton bollworm, and is not easy to make pests resistant to drugs. It is safe for human and livestock and can be mixed with most pesticides.

At present, copper pyridinethione is mainly used in marine antifouling paint, architectural coating, metal processing, pesticide and other industries. It has excellent properties of high efficiency, environmental protection, low toxicity and broad spectrum. It has great potential in the field of pesticide.
