Distribution of propylene glycol, glycerin, triethanolamine, AES, AOS variety, reasonable prices. Guangzhou Yang Qing Chemical Co., strength propylene glycol, 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 glycol acrolein hydration route relatively mild reaction conditions, propylene glycol Dow technology is not difficult, the hydrogenation process is mature, simple catalyst system content do not ask for equipment, investment costs are relatively low-propanediol , but higher raw material 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.
