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, propylene glycol Korea SKC, variety principles of operating characteristics and puerile, and win the trust of our customers. Main: Dow propylene glycol, SKC hydration of acrolein hydrogenation of propylene glycol were prepared using 1,3-PDO, it has also made stage findings, the research laboratory built on the basis of 50t / a pilot plant. Hydration processes using chelating type polystyrene ion exchange resin catalyst in a fixed bed reactor, at a space velocity of 1h-1, acrolein concentration of 15% to 17%, the hydration reaction is carried out at 60 ℃, the acrolein conversion was 83.2% , 3-hydroxypropionaldehyde (3-HPA) selectivity of 93%; when 3-HPA hydrogenation at 60 ℃, 5.0MPa, WHSV conditions 9h-1, the conversion was 96.6%, 1,3 -PDO selectivity of 99.6%. 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, food-grade propylene glycol, won the trust of our customers. Main: Dow propylene glycol, SKC glycol shell company created by the production process advantages are low cost, advanced technology and good product quality; but there is also a large upfront investment, pharmaceutical grade propylene glycol, the reaction difficult enough. The presence of the complex process of hydrogenation refining system, and several low-pressure steam sweep in the process, so the higher investment costs and operating costs, if the development of effective hydrogenation catalyst, stable propylene glycol, reducing the use of excess hydrogen reaction volume, and increase the activity of the catalyst, the process cost can be further reduced. Key aspects of this technology is the choice of the catalyst, the current domestic processing in this respect is not mature, domestic factors influence the development of the production process is the lack of research funding and technology exchange stability propylene glycol industrial grade _ _ Y-Chemical (view) By Jan-Chemical Co., Ltd. in Guangzhou.
