Thermal immobilization of carboxy functionalized polysiloxanes: Practice and mechanism

Summary The thermal immobilization of polysiloxanes bearing carboxyalkyl functional groups has been investigated. Under conditions of reduced carrier-gas flow, in particular with water vapour saturated, carrier-gas, high degrees of immobilization could be achieved at moderate temperatures (<200°C). The mechanism of immobilization is shown two involve condensation of carboxyl groups of the polysiloxane with silanol groups either originally present in the polymer or formed during the immobilization process. Other polysiloxane stationary phases could also be immobilized under similar conditions when mixed with carboxyalkyl polysiloxanes. In particular, cyanoalkyl silicones which are otherwise difficult to crosslink, are amenable to this form of immobilisation.

Research and Practice in Green Chemical Technologies

Green chemistry is also called environment harmless or environment friendly chemistry.Green chemistry requires to use new synthetic methods, engineering technologies and processes to eliminate or reduce by-products, wastes or products that harmful to human health, community safety,and ecology environment. Green chemistry pursues to control the usage of the harmful and toxic materials, reduce waste emission, avoid necessity to treat the wastes; Green Chemistry advocates wastes management from the beginning, improving the efficiency of atoms, optimizing the use of resources and energy, lowering the cost of production. Green Chemistry technologies are the ultimate path to the clean chemical production in the future.Insight Co. takes "hospital of enterprises" and "bank of technologies" as our characteristics in business, and deems the development and spread of green chemistry as our mission. We developed an unique business model which combines education, research and production. In the past 8 years,we had applied and obtained more than 30 patents and received more than ten national and provincial awards in technology progress.We had made great progress in the manufacturing of organophosphorus pesticides, especially the production of omethoate, methamidophos, paraquat and glycyrrhizinic phosphor, etc., which made a stable foundation for INSIGHT's development. We had also achieved great success in the high efficiency low toxic pesticides, such as imidacloprid, etofenprox, metalaxyl and in the new synthetic methods in various amino acids as well as in the pharmaceutical intermediates. The new method of preparation indigo using N-phenylglycinonitrile is an advanced process in the world in terms of the clean production technology for Ferro cyanide and HCN's transformation rate improvement. We solved the pollution problem of the old route. The newly developed substituted product for indigo using a clean production technology which greatly reduced the material consumption and environmental pollution. Insight has facilities producing nearly 20 photo-initiators and developed the new technique for light-curing lubricity, water-born resin, the technique for water-bon coating and their associated applications. The successfully developed technology of new high performance emulsion will promote the technology advancement in the coating industry and the wide spread of new coating in China.Insight has developed a series of new technologies, including a novel reactor technology - using a newly designed patented blade, has been characterized as high efficiency & energy saving reactor.The novel technology research and development are widely applied in INSIGHT's ten-year practice.We studied and confirmed the non-thermal catalyzing effect of microwaves, proposed a "weak microwave" theory, and a chemical reaction rate equation. We proposed that in the existence of microwave magnesium ions and phosphate, amino acid can be activated to form peptide which maybe the path of the origin of life.A 3000mt/a pilot plant in Chongqing using carbon monoxide and hydrogen to produce dimethyl ether in a single step has been built via collaboration with the Dept. of Chemical Engineering at Tsinghua University.
