摘要: The present invention relates to a synthesis method and synthesis reactor of high-selectivity 2-methylallyl chloride by taking isobutylene and chlorine gas as raw materials and performing a gas-phase chlorination reaction in a microchannel reactor with a cooling surface. The isobutylene and the chlorine gas are reacted in a T-shaped microchannel reactor, and the mixing speed is extremely fast. Meanwhile, the huge heat exchange area per unit volume can ensure that the reaction proceeds stably at a substantially constant temperature and has good controllability. Therefore, side reactions caused by excessive local temperature can be effectively suppressed, the reaction selectivity is high, and no coking phenomenon occurs.

摘要: The present invention relates to a method for preparing a polyether amine catalyst, and polyether amine. A polyether amine catalyst is a supported metal catalyst; γ-Al2O3 is used as a carrier; basic cupric carbonate, basic nickel carbonate and basic cobalt carbonate are used as precursors of supported metals; and the polyether amine catalyst is prepared by performing twice adsorption roasting and once reduction by means of an equivalent-volumetric impregnation method. Easier decomposition is achieved by using basic carbonate, and only water and carbon dioxide are generated, such that processes and costs for treating waste gases can be saved. By using the polyether amine catalyst to prepare polyether amine, a conversion rate and primary amine selectivity can be improved, and the color of products can be reduced. Therefore, the obtained polyether amine can have higher activity and wider application.

摘要: Disclosed are to a supported catalyst used for synthesizing polyether amine, and a preparation method and use thereof. The supported catalyst introduces Mo and CeO2 into Ni and Cu active components. By means of the cooperation of Ni, Cu and Mo, CeO2 and Ni form more active sites, such that the supported catalyst can have high reaction activity and selectivity. By using the supported catalyst to synthesize polyether amine, the amination efficiency and selectivity of polyether polyol can be greatly enhanced, thereby preparing the polyether amine with light color and narrow molecular weight distribution. In addition, the cost of the catalyst can be reduced, a process condition is relatively mild, and the disadvantage of low reaction activity of a nickel-based catalyst in synthesizing small molecule polyether amine can be overcome, such that the supported catalyst has a desirable industrial application prospect.
