A review on direct synthesis of dimethoxymethane
文献摘要：
Polyoxymethylene dimethyl ethers are recognized as the prospective diesel additive to decrease the pol-lutant emission from the light-duty vehicles,which can be polymerize form the monomer of dimethox-ymethane(DMM).The industrial synthesis of DMM is mainly involved two-step process:methanol is oxidized to form the formaldehyde in fixed bed reactor and then reacted with the generated formalde-hyde through acetalization in continuous stirred-tank reactor.Due to huge energy consumption,this typ-ical synthesis route of DMM needs to be upgraded and more green routes should be determined.In this review,four state-of-the-art one-step direct synthetic routes,including two upgrading routes(methanol direct oxidation and direct dehydrogenation)and two green routes(methanol diethyl ether direct oxida-tion and carbon oxides direct hydrogenation),have been summarized and compared.Combination with the reaction mechanism and catalytic performance on the different catalysts,the challenges and oppor-tunities for every synthetic route are proposed.The relationships between catalyst structure and property in different synthesis strategy are also investigated and then the suggestions of the design of catalyst are given about future research directions that efforts should be made in.Hopefully,this review can bridge the gap between newly developed catalysts and synthesis technology to realize their commercial appli-cations in the near future.
