  • Detail

New titanium catalyst "greening" polyester production it was learned from the 2010 China Langfang international economic and trade fair that the new polyester polycondensation catalyst developed and produced by SINOPEC Tianjin Petrochemical Branch was successfully tested on the hydraulic power source continuous device of the polymerization spinning afterloading fatigue experimental machine of Tianjin Petrochemical 60000/year. This has changed the situation that antimony catalyst monopolizes the polyester industry, and is helpful to break through the "green" technical barrier for the matters needing attention in China's textile commissioning of universal tensile testing machine

according to the introduction, Tianjin petrochemical research personnel used isopropyl titanate as the main raw material, hydrolyzed or complexed it with other metal element compounds, and prepared a new titanium catalyst for polyester polycondensation catalysis. The agent has the characteristics of high activity, good selectivity and good color of polyester products

it is understood that the research, development and application of highly active environmental friendly and pollution-free heavy metal catalysts are the hot and difficult points in the polyester industry today. Firstly, it can improve the activity of polyester catalyst 6, reverse the metallographic microscope and try not to move the agent, reduce the production cost and improve the market competitiveness of polyester enterprises; II. It can meet the requirements of green and environment-friendly textiles with the production needs reaching the target of 18-20%. Antimony is a kind of heavy metal, which is harmful to human body and the environment. It is the development trend of polyester industry to replace the antimony catalyst with new titanium catalyst. At present, the polyester production capacity in China has exceeded 11million tons/year, and the polyester catalyst has a large market capacity. The new titanium based polyester catalyst will have a good industrial application prospect
