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 of operating characteristics and puerile principle of 1,3-propanediol, has won the trust of our customers. Main: Dow propylene glycol, SKC glycol first developed by the Do Pont company, mainly through strain with glycerol as a substrate fermentation 113- food-grade propylene glycol, 3-PDO, the process at home and abroad are in the research stage. Selection and training of bacteria is the key, the current study is more bacteria are Klebsiella, Clostridium butyric acid, lemon Freund three strains of bacteria, they have a high conversion rate of 1,3-PDO and manufacturing strength. Some foreign research institutions through the use of gene technology 13- glycol manufacturers, selected bacteria, DNA recombination, to improve the yield of 1,3-propanediol. As a result of the world at present genetically engineered bacteria fermentation production of 1,3-propanediol, only DuPont family, thus DuPont patent application by the relevant technologies and processes were well protected, the formation of a high degree of technical monopoly 13- glycol origin _ Yang Qing Chemical (certified) _ Guangdong 1,3-propanediol by Jan-Chemical Co., Ltd. in Guangzhou.
