Chemical formula C4H6O5 C.A.S number 004-525-33-1 Formula weight 134.09 Appearance Colourless liquid Assay Not less than 99.8% Density 1.25g/cm3(20C/68F) Application Using for the different beverages: flavored water energy drinks tea drinks juice till 100% Mechanism of efficiency of DMDC DMDC can permeate through the cell membrane, and block the metabolism through reacting with the enzymes of microorganism, then achieve the purpose of sterilization. Even in very low additive amount, DMDC can effectively kill typical spoilage bacteria in beverage, and not affect the taste, flavor and color of the beverage. Furthermore, it could be rapidly and completely hydrolyzed to carbon dioxide and methanol, which are the natural ingredients of juice.

Propylene Carbonate CAS MO.:108-32-7 Purity:99.5% 250kg/drum For price, specification and other details please contact us..
Propylene carbonate is an organic compound with the formula CO. It is a cyclic carbonate ester derived from propylene glycol. This colorless and odorless liquid is useful as a polar, aprotic solvent. Propylene carbonate is chiral, but is used as the racemic mixture in most contexts. For price, specifications and other details please contact us.
Propylene carbonate (molecular formula: C4H6O3) is a colorless, odorless, flammable liquid. Miscible with ether, acetone, benzene, chloroform, vinyl acetate, etc., soluble in water and carbon tetrachloride. It has a strong ability to absorb carbon dioxide and is stable in nature. In industry, it is obtained by adding propylene oxide and carbon dioxide under a certain pressure, and then distilling under reduced pressure. It can be used as oily solvent, spinning solvent, olefin, aromatic hydrocarbon extractant, carbon dioxide absorber, dispersant for water-soluble dyes and pigments, etc. Application 1. It can be used as an excellent medium for high-energy batteries and capacitors in the electronics industry. 2. In the polymer industry, it can be used as a solvent and plasticizer for polymers. 3. Used as a plasticizer for adhesives and sealants. 4. It can also be used as a phenolic resin curing accelerator and a dispersant for water-soluble adhesives, pigments and fillers. 5. The chemical industry is the main raw material for synthesizing dimethyl carbonate. It can also be used to remove carbon dioxide and hydrogen sulfide from natural gas and petroleum cracking gas. 6. It can also be used in textile, printing and dyeing and other industrial fields.
