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, and propylene glycol organic acid fermentation broth is not easy crystallization characteristics, adding an appropriate amount of propylene glycol fermentation broth pharmaceutical grade mineral acid, the fermentation broth of organic acid is replaced with organic acid, while generating the corresponding inorganic salt; fermentation broth was concentrated, so that the inorganic salt crystallization, thereby separating the fermentation broth; concentrated broth into a propylene glycol, succinic acid, lactic acid, acetic acid, glycerol and 2,3 - a mixture of butanediol, and the mixture was vacuum distillation, 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.

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 De1,3- propylene glycol (1, 3- PDO) is a colorless, odorless liquid food-grade propylene glycol, the proportion of 1.0537 (25 ℃), melting point -32 ℃, boiling point 210-211 ℃, spontaneous combustion temperature 400 ℃. Soluble in water, alcohol and ether, it is a flammable, low toxicity of the compounds. Slightly soluble in benzene and chloroform, the chemical nature of the performance reflects the typical propylene glycol alcohol and what price, to produce an ester and after acid. 2 use of 1,3-propanediol (PDO) is an important chemical raw material, can be used as organic solvents used in inks, paints, lubricants, antifreeze agent industry, also used in drug synthesis intermediates. Its main use is as polymer synthesis monomers excellent performance polymer materials. The main use is as a monomer and terephthalic acid polyester synthesis of new materials - polyethylene terephthalate (PTT) food-grade propylene glycol, Jan-Chemical (certified), propanediol from Guangzhou Zhongshan Yang Qing Chemical Co., Ltd. provided.
