Advances in acetalization synthesis of polyoxymethylene dimethyl ethers
摘要
Abstract
Polyoxymethylene dimethyl ether compounds have high oxygen contents and cetane numbers (CN), low condensation point and cold filtration point, are promising environmental protection diesel additive to improve diesel combustibility, enhance combustion efficiency, and reduce emission of NOx and carbon smog pollutants. In this review, latest achievement in catalyst system, reaction mechanism and synthesis kinetics of polyoxymethylene dimethyl ether by acetalization reaction was summarized. The catalyst systems included liquid acid, solid acid, and ionic liquid systems in literature. The reaction materials contained end-group (—CH3,—OCH3) provider such as methanol, methylal and dimethyl ether, which were downstream products of methanol, and chain segment (—CH2O—) provider such as 1,3,5-trioxane (TOX), paraformaldehyde (PF) or formaldehyde (FA). Synthesis kinetic models and parameters of polyoxymethylene dimethyl ethers were reviewed briefly. The acetalization and kinetics research are moving towards the direction that benefits large scale commercial production.关键词
