Abstract
The performance indexes of polyoxymethylene dimethyl ethers as diesel additives are presented.Based on the classification of different reaction materials,the advantages and disadvantages of several synthetic processes for polyoxymethylene dimethyl ether are compared.It is found that the processes with methylal and paraformaldehyde respectively as raw materials have certain advantages than others.The future research direction of polyoxymethylene dimethyl ether is discussed,which is suggested to follow up improvement of catalyst reliability and development of low-cost catalyst.
