Zibo Baoding Chemical Industry Co., Ltd. was established on 1996. The main product is Dimethyl Carbonate (DMC) produced by Ester-Exchange process.Dimethyl Carbonate (DMC) is used for producing Ciprofloxacin, Furazolidone, Norfloxacin... Dimethyl Carbonate (DMC) is also used as a good organic solvent.

Dimethyl Carbonate

Dimethyl Carbonate as a kind of Organic Synthesis Intermediate Body with micro toxicity. Water white, transparent and volatile liquid. named "Green basic chemical material". Its use very extensive, reactive chemical property. Molecule including three kinds of functional body for methyl, carbonyl, carbomethoxy, so as to proceed a series of reaction with kinds of Alcohol, Phenol, Amine, Ester, Amino-Alcohol. DMC as Methylating agent, carbonylation agent and carbomethoxy agent could take the place of COCl2, (CH3)2SO4, CH3Cl or ClCOOCH3 with drastic toxicity to produce Methyphenate, phenolicether, carbonate, isocyanate, ester carbonate, conveniently to compose advanced resin, pesticide-intermediate body, food additive, anti-oxidant, surface active agent, and other fine chemical products. As a kind of efficient solvent with good property, it could take the place of Armoatic Hydrocarbon solvent: Another use, as gasoline additive, increase octane value and oxygen content of gasoline to manufacture gasoline without lead. So DMC is called "New Foundation Stone" of organic synthesis.

1,2-Propanediol

Structural Formula: CH3CHOHCH2OH

Relative Molecular weight:76.09

Appearance: Water-white sticky-thick liquid with pungent flavor.

Chemical Characteristics and Use:

1,2-propanediol could react with Biatomicaid, Aqua fortis, chlorhydric acid, sulfuric acid etc. After dehydrating water, it could be produced oxypropylene or polyethylene glycol. It could be capatible with water, alcohol, dimethyl ether, chloroform, Acetone etc. Organic solvent. Dissolved degree of 1,2 propanediol is small for hydrocarbon, chloro hydrocarbon, Oil and Fat, but its dissolved capacity is stronger than that of ethylene glycol. 1,2-propanediol has extensive use, as solvent of perfume and edible pigment in foodstuff, as the solvent of controlled medium, presservative, paste, vitamin, penicillin in parmaceutical industry, also could be as tobacco lubricated solvent, preservative, solvent for accelerating the ripening of fruit, preservative, anti-icing fluid, heat-carrier etc. 1,2-propanediol is used to produce Non-saturated alkyd resin, plasticizer. Surface active agent etc.

Quality Standard:Industrial Grade, Pharmaceutical Grade

Packing: 200kg/barrel (galvanized iron barrel).
