Introduction to DMC Catalyst

 The DMC catalyst has a freezing point of 4 ℃ and a boiling point of 90 ° C. It is a colorless transparent liquid with a slight aromatic smell at room temperature. It is easy to volatilize and has the appearance similar to alcohols, esters and ketones. It can be miscible with organic solvents in any proportion, such as alcohol, ester, ketones. It is non corrosive and partially soluble in water with a solubility of 13.9g/100gH2O. Water can also be partially soluble in DMC with a solubility of 4.2gH2O/100gDMC.

     

Single bimetal cyanidation has no catalytic activity, and only DMC complex formed by DMC and ligand complexation can show catalytic activity. The zinc-Cobalt cyanide complex is the most suitable for the preparation of polyether polyol with low unsaturation and narrow relative molecular weight distribution.

 

DMC catalyst is a kind of non-toxic chemical raw material with excellent environmental protection performance and wide application. It is an important intermediate in organic synthesis. It contains functional groups such as carbonyl, methyl and methoxy in its molecular structure. It has a variety of reaction properties and has the characteristics of safety, convenience, less pollution and easy transportation in production. DMC catalyst is a promising green chemical product because of its small size. It is also an important organic chemical intermediate, because its molecular structure contains carbonyl, methyl, methoxy and carbonyl methoxy, so it can be widely used in organic synthesis reactions such as carbonylation, methylation, methoxylation and carbonyl methylation.

 

Since DMC catalyst is non-toxic, it can replace highly toxic phosgene, methyl chloroformate, dimethyl sulfate as methylating agents or carbonylation agents to improve the safety of production and operation, and reduce environmental pollution.

Acetyl Chloride

  Features of Acetyl Chloride Product Name: Acetyl chloride Chemical Formula: C2H3ClO Acetyl chloride cas : 75-36-5 Dangerous Grade: 3.2 Technical Data of Acetyl Chloride ITERMS SPECIFICATION Appearance Colourless transparent liquid Assay ≥99.0% Phosphorus content ≤0.02% Package and Storage: 200kg/drum Store in a cool, dry place. Keep container closed when not in use Application /Application Industries: Acetylation reagent Pharmaceuticals Dye Acetyl chloride is a colorless flammable liquid with a pungent odor. It is violently decomposed by water or ethanol. Dissolved in chloroform, ether, benzene, petroleum ether or glacial acetic acid. Acetyl chloride is an irritant and corrosive agent. Contact with the skin can cause burns, and steam can strongly irritate the eyes and mucous membranes. When people inhale 2 ppm, they can feel the stimulating effect. Short-term exposure to higher concentrations of acetyl chloride may cause death or permanent damage. The amount of aquatic live poisoning

What is GLycolic Acid?

  We like to focus on the ingredients of beauty products. But we prefer to touch the product and explore whether it really works. Alpha hydroxy acid is also known as AHA. It includes glycolic acid , lactic acid and citric acid. These products do not meet the needs.   Now we analyze the most popular ingredient in the world - glycolic acid.   Glycolic acid is a naturally occurring substance that is added to skin care products. It is good for the skin and restores skin elasticity and moisturization. The original state of glycolic acid is a powder composed of colorless crystals. It is tasteless. Let's first understand its benefits and its related products.   The Benefits of Glycolic Acid Glycolic acid is very effective for skin treatment because of its high purity. The premise is safe and correct use. Many skin care products contain glycolic acid. Sensitive muscles can also be used. Glycolic acid is non-irritating and it can be used in skin care. Add more glycolic acid to the facial cl
