2000年10月24日由中科院高技术研究与发展局组织专家对中科院理化技术研究所(原中科院感光化学所)承担的“新型杂多酸催化剂研制及其在聚四甲撑醚二醇(PTMEG)合成中的研究”专题进行了验收。与会专家认为:该专题基本完成了合同规定的研究内容,达到了合同规定的主要技术经济指标。其中,自主开发的杂多酸(12-钨磷酸)制备工艺,具有工艺简便、安全、产率高的特点,已申请发明专利,并实现了12-钨磷酸批量生产,产品质量符合规定要求;杂多酸(12-钨磷酸)作为生产PTMEG的聚合催化剂的应用研究,取得了良好的结果,聚合物分子量分布优于进口产品,使我国的PTMEG生产技术有所
October 24, 2000 by the Chinese Academy of Sciences Institute of High Technology Research and Development experts in the Institute of Physics and Chemistry Chinese Academy of Sciences (formerly Chinese Academy of Sciences Institute of Photochemistry) commitment “new heteropolyacid catalyst development and polytetramethylene ether glycol (PTMEG ) In the study of synthesis ”topic has been acceptance. Experts at the meeting held that: The topic basically completed the research content stipulated in the contract and reached the major technical and economic indicators stipulated in the contract. Among them, the self-developed preparation process of heteropoly acid (12-tungstophosphoric acid) has the advantages of simple process, high safety and high yield, has applied for invention patent, and has realized mass production of 12-tungstophosphoric acid, and the product quality meets the requirements; Heteropoly acid (12-Tungstophosphoric acid) as a catalyst for the production of PTMEG polymerization research, and achieved good results, the polymer molecular weight distribution is better than imported products, so that our country PTMEG production technology
