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.

The Difference Between Nitrile Rubber and NBR LatexThe Difference Between Nitrile Rubber and NBR Latex

  Affected by public health incidents, NBR latex   is like a dark horse that has attracted the attention of the international market. Nitrile rubber and NBR latex are very different in use.   1. The difference in performance between nitrile rubber and NBR latex Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high abrasion resistance, good heat resistance, and strong adhesion. . Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. Nitrile rubber is mainly used to make oil-resistant rubber products.   Carboxylic nitrile latex is obtained by introducing methacrylic acid or methacrylate ternary copolymer during polymerization. Since the carboxyl nitrile nitrile latex introduces a more polar carboxyl group into the molecular backbone, it furt...

Difference Between Sodium Laureth Sulfate And Sodium Lauryl Sulfate

Sodium laureth ether sulfate  (SLS) and sodium lauryl ether sulfate (SLES) are surfactants that play a role in foaming products. It is widely believed that the foam produced by a product is its performance. The composition of SLS and SLES reduces the surface tension of water. They can also be used as dispersants to properly mix spices and body spray. SLS and SLES can also be used in a variety of personal care products such as soap, shampoo, shower gel, toothpaste and other foaming products. SLS and SLES are also added to moisturizing lotions and sunscreens because of these properties. The difference between SLS and SLES is in the manufacturing process. SLS undergo a process called ethoxylation. And then you get SLES. Why do we have this ethoxylation process? Because SLS has some mild irritation on the skin, such as dry. The manufactured SLES are more gentle and do not irritate the skin. Many manufacturers do not use SLS because it is irritating. SLES should be softer o...
