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 levels, variety principles of operating characteristics and puerile, and win the trust of our customers. Main: Dow propylene glycol, SKC glycol Degussa Division warehouse earliest use of special ion exchange resin catalyst at 60 ℃, Nanning propylene, acrolein conversion was 82%, HPA selectivity of 80%. After using H3P04 / Ti02 buffer solution and organic acid / organic amine catalyst composition. HPA is hydrogenated to reduce the content of the reaction product of a carbonyl group, Degussa company two-stage hydrogenation manner, carbonyl content can be reduced to 100ppm or less. Degussa company in 1998 to transfer the technology from DuPont. 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 Shanghai Petrochemical Research PDO hydrogenation of acrolein hydration process, and built a pilot plant in 2001 to produce qualified products. Acrolein hydration and subsequent hydrogenation steps were cation exchange resin catalysts and nickel-based catalyst, acrolein hydration-way conversion rate 45% -55%, HPA selectivity of 95%, propylene glycol what price, which add the conversion rate of argon and selectivity close to 100%, propylene prices, products PDO purity of 99.9%. Heilongjiang Petrochemical Research Institute in 2001, assumed the "50 tons / year hydrogenation of acrolein hydration legal PDO pilot" project, and in 2006 passed the acceptance of Heilongjiang Province Science and Technology Department, formed with independent intellectual property rights of technology glycol manufacturers , Jan-Chemical, Nanning glycol provided by Jan-Chemical Co., Ltd. in Guangzhou.
