Development of the synthesis technology of polyoxymethylene dimethyl ethers
摘要
Abstract
Polyoxymethylene dimethyl ethers is a new product of coal chemical industry. As a good additive for diesel fuel,it has advantage in environmental protection. The latest advances on the synthesis technology of polyoxymethylene dimethyl ethers were reviewed. According to the starting materials,the synthesis technologies can be divided into four types,using①methanol and trioxane,②methylal and paraformaldehyde,③methylal and formaldehyde gas,and④methanol and formaldehyde. The four mainstream techniques and the industrialization status were briefly introduced, respectively. Lacking of policy support and facing opposition from the oil industry are the two major issues for polyoxymethylene dimethyl ethers which should be solved before it enters the market. Finally,this article especially points out that we should put the emphasis of future research of polyoxymethylene dimethyl ethers on reducing the costs. What we need to do is to take effective measures to remove negative influence of water for the methanol and formaldehyde route. Meanwhile, the performance of the catalyst should be further optimized to control the proper distribution of products and improve the efficiency of the synthetic reaction.关键词
