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.

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...

Difference Between Sulfate And Sulfonate In Shampoo

  Sulfates and sulfonates have two things in common. First, they're all anionic surfactants. Second, they are often used for personal care applications. But there are many differences. They have different molecular mechanisms. They have different functions and they have different raw materials.   Sulfates Sulfate is a compound. It has carbon bonds and oxygen and sulfur bonds. They include substances such as sodium lauryl sulfate and sodium lauryl ether sulfate.   At low pH, these substances plus the c-o-s bond hydrolyze to produce alcohol and inorganic sulfate. At a high pH, sulfate is stable in the base and, if ethoxylated to a relatively high level, produces a low-foaming alkali-soluble surfactant. Sulphates can be prepared by reaction of fatty alcohol or fatty alcohol ethoxylates with reagents such as SO3 or chlorosulfonic acid (CSA).   The reason shampoo becomes thick foam in the shower is that it contains sulfate. Most shampoos and household cleansers contain su...

What Are the Advantages of DMC Catalyst?

DMC catalyst is a new type of high-performance catalytic olefin oxide ring-opening polymerization catalyst, suitable for synthesis of olefin oxide polyether containing 1-6 functional groups. DMC catalyst manufacturers usually use low molecular weight organic complexing agents. The complexing agents beneficially affect the activity of the catalyst for epoxide polymerization. The production of polyether with DMC catalyst has the following advantages: Low production and running costs 1) No post-processing process and faster reaction speed increase the production capacity of the device by several times. 2) No post-treatment process reduces equipment investment, unit product energy consumption and water consumption, unit product solid waste and waste water production, and improves product yield. 3) It can produce higher molecular weight products with molecular weight of more than 2000 per mole of hydroxyl group. 4) The produced polyether has the characteristics of narrow molecular weigh...
