Frbiz Reports Polyurethane Intermediates Industry Go The Way Of Renewable Resources-bloxorz

Arts-and-Entertainment As oil prices continue to ratchet up production of polyester, polyether polyol raw material prices soaring. Natural oils as a renewable resource, its production of polyurethane intermediates as raw materials, cost advantages are apparent. To this end, the National Development and Reform .mission will produce 50,000 tons of polyester resin and oil-based polyol continuous production equipment development, included in the 2007 national major industrial technology development projects, has entered the installation phase. Forest Products Chemistry, Chinese Academy of Forestry Zhou Yonghong, deputy director of Industry Research Institute said that the project is .pleted, polyurethane (PU) intermediate production is expected to woody oil, waste oil and turpentine and other large-scale substitution of petroleum toxic chemicals, lead Polyurethane upgrading of industrial technology, to improve the level of clean production process. Oils rich in natural resources Currently used in PU production of raw materials, intermediates mostly from oil, coal, natural gas and other mineral resources, and more for the phthalic anhydride, phthalic acid, propylene oxide and other toxic chemicals. According to Zhou Yonghong, currently about 7,000 yuan per ton price of rosin, oil more than 6000 yuan per ton, waste oil price of about 4,000 yuan / ton, while the price per ton of propylene oxide and up to 15,000 yuan, 10,000 yuan is also more than a tonne of phthalic anhydride. And petrochemical raw materials, polyester, polyether polyols, .pared to the natural oils as raw materials cost polyester polyols, performance and environmental protection has a distinct advantage. Line of polyurethane raw materials change became a major issue for sustainable development industry. China has rich natural oil resources, which can adopt the annual amount of resin 2 million tons more than the current output of about 80 resin tons / year, ranking first in the world. Processed by the rosin resin and turpentine, is an important chemical raw material. Meanwhile, China also has the development of other woody oils advantages. 2015, China’s woody oil production will more than 10 million tons. In addition, China’s annual oil production expected to foot oil and garbage and recycling waste oil, oil of about 500 million tons. Therefore, the use of cheap rosin, woody waste oil and other natural fats and oils, alternative or partial alternative to expensive anhydride, phthalic acid and propylene and other petrochemical polyurethane raw material production, will have good performance and a more eco- strong market .petitiveness. Technical bottlenecks have been over.e While oil production from the natural resources point of view of polyurethane material is feasible, but practical to implement the technical problems still exist. According to reports, the main oil-based polyol production using vegetable oil molecule chain double bond to epoxidation, hydroxylation and then made of. As the peerless vegetable oil molecules and epoxide bond separation difficulties, together with the raw materials used for hydroxylation have a significant impact on product performance, so the shares can not be replaced more oil quality polyester and polyether polyols. And now oil polyol synthesis process is still liquid acid catalyst and hydrogen peroxide epoxidation reagents such as the production process pollution. The only national forest biomass resources dedicated to chemical processing and utilization of Chinese Academy of Forestry Forest Research Institute of Chemical Industry, 90 from the last century began to Rosin polyester polyols and rigid polyurethane foam of the study. They Rosin polyester polyols by and foam production process, product performance and optimize the performance of polyurethane to improve .patibility, has developed a unique technology in 2004, the first in China to achieve at the same time as co-generation biodiesel dimer improve the economics of biodiesel. As dimers instead of phthalic anhydride, phthalic acid and other polyester polyols for the production of major raw materials, the researchers again dimer prepared by transesterification of polyester polyol has been systematically studied, set up an annual output of 500 tons of oil-based polyol in pilot production line. According to the natural oil production performance of polyurethane products have reached the level of petrochemical products. About the Author: 相关的主题文章:
