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 glycol according to incomplete statistics, as of September 2010, the global propylene glycol (PG) of the total capacity of about 2.1 million tons / year of 1.2 propylene glycol content, in 2005 this figure was only 1.43 million tons the growth rate is very fast. One of the biggest producers of the Dow, accounting for one third of total production, followed by Leander accounted for 24%. Propylene glycol producers mainly in North America, the annual output of 610,000 tons, followed by Europe, the annual output of 540,000 tons. In Asia, mainly Japan, South Korea and Singapore, which is home to these regions export less propylene glycol causes. . 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 hydration of acrolein hydrogenation of propylene glycol were prepared using 1,3-PDO, the results have also been achieved phase-propylene glycol role in 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 1.2-propylene glycol, the airspeed 1h-1, acrolein concentration of 15% to 17%, the hydration reaction is carried out at 60 ℃, Acrolein conversion was 83.2%, 3-hydroxy-propionaldehyde (3-HPA) selectivity of 93%; when 3-HPA hydrogenation at 60 ℃, 5.0MPa, the feed under conditions 9h-1 space velocity, the conversion was 96.6%, 1,3-PDO selectivity of 99.6%. Yunfu 1,2-propanediol, 1,2-propanediol purpose, Jan-Chemical (certified merchants) are provided by Jan-Chemical Co., Ltd. in Guangzhou. Road Zhiyuan, temper forward.
