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, Chengmai propylene glycol, has won the trust of our customers. Main: Dow propylene glycol, SKC glycol acrolein hydration route relatively mild reaction conditions, technology is not difficult, the hydrogenation process maturity, propylene glycol manufacturer, the catalyst system is simple, less demanding on the equipment investment cost is relatively low, but the raw materials higher costs, the economy is lower than EO hydroformylation process and fermentation processes. In order to remain competitive, acrolein craft the best means integral with propylene production, and avoid crude acrolein purification step. Because acrolein itself there are some environmental issues, acrolein PDO production costs are relatively high, the outlook is not very optimistic. 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 glycol, propylene glycol what price, SKC propylene acrolein hydration reaction (1) heterogeneously catalyzed acrolein acrolein hydration hydration 3-hydroxypropionaldehyde earliest use of H2SO4, H3PO4 inorganic acids and acid salts as The catalyst, but its low yield, poor selectivity, most acrolein case of acid condensation or polymerization reaction of two acid ether. Chengmai propylene glycol level _ _ Y-Chemical (high-quality businesses) are provided by Jan-Chemical Co., Ltd. in Guangzhou. Road Zhiyuan, temper forward. Guangzhou Yang Qing Chemical Co., Ltd. (www.gzyangqing.com) (www.gzyangqing.com) aims to become and you win symbiosis, strategic partners to move forward, more determined to become the most influential agents of chemical products business, and You leap together, succeed together!
