Main: Dow propylene glycol, SKC glycol boiling point melting point ℃ -27 ℃ (101.3kPa) 214.0 Flash Point ℃ 80 vapor pressure KPa (20 ℃) ??0.008 relative density D201.0554 refractive ND1.4389 dynamic viscosity m / s46 explosion limit: 2.6-12.6% V / V of solubility in water, alcohol, ether and formamide immiscible, slightly soluble in benzene and chloroform security flammable, encountered strong oxidants causing fire hazard toxicity LD50325.5mg / kg. rat oral 1, 1,3-propanediol alias 1,3-dihydroxy propane English name 1,3-propanediol or 1,3-dihydroxypropane, Acronym PDO, CAS No. 504-63-2. The product is a colorless or pale yellow transparent viscous liquid, no odor, molecular formula C3H8O2. Structural formula HOCH2-CH2-CH2OH. A molecular weight of 76.09. Guangzhou Yang Qing Chemical Co., Ltd. Distribution of propylene glycol, glycerin, triethanolamine, AES, AOS variety, reasonable prices. Guangzhou Yang Qing Chemical Co., strength, credit, keep the contract, to ensure product quality, variety principles of operating characteristics and puerile, and win the trust of our customers. Main: Dow propylene glycol, SKC propylene glycol extraction and extraction process uses, which belongs to the technical field of chemical separation. The process is easy to use inorganic salt crystallization 1.3 food-grade propylene glycol, propylene glycol and organic acid fermentation broth is not easy crystallization characteristics 1.3 propylene glycol, propylene glycol, adding an appropriate amount in the fermentation broth of an inorganic acid, the organic acid fermentation broth replaced with an organic acid, to form the corresponding mineral acid salt while; fermentation broth was concentrated inorganic acid such crystallization, thereby separating the fermentation broth; broth into a concentrated propylene glycol, succinic acid, lactic acid, acetic acid, glycerol, and propylene glycol 2,3-butanediol was 1.3 model, and the mixture was vacuum distilled to obtain the components of the product. Advantageously, propylene glycol and 2,3-butanediol obtained at the same time, the fermentation broth is about to remove salts, also received succinic acid, lactic acid and acetic acid and inorganic salt products, reducing waste emissions, increase the overall benefits of production. 1.3 propanediol Model | Zhongshan 1.3 propanediol | Jan-Chemical provided by Jan-Chemical Co., Ltd. in Guangzhou.
