摘要： The present invention relates to a supported catalyst used for synthesizing polyether amine, a preparation method, and an application. 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.

摘要： Provided are a system and a method for preparing a polyether amine by catalytic amination of a polyether diol. The preparation method includes: filling a catalyst into the fixed bed reactor; pressurizing the internal pressure of the fixed bed reactor to 10˜13 MPa by a hydrogen gas, and raising the temperature of the fixed bed reactor to 150˜185° C.; adjusting the temperature of the multi-stage preheater so that the feeding temperature of a raw material reaches 125˜135° C.; and simultaneously feeding a polyether diol, liquid ammonia and the hydrogen gas into the multi-stage preheater, and after mixing and preheating, introducing into the fixed bed reactor from the feed inlet of the fixed bed reactor for a continuous catalytic amination reaction. The total amine value of the polyether amine finally obtained by the present invention reaches 28˜32 mgKOH/g, the color reaches 10˜20, and it is colorless transparent liquid.

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 2-methylallyl chloride from 1,2-dichloroisobutane. The method is characterized in that 1,2-dichloroisobutane and a sodium hydroxide aqueous solution are used as raw materials; reactive rectification is performed in a combined rectifying tower to eliminate hydrogen chloride so as to obtain 2-methylallyl chloride. A plate tower is provided at the lower part of the combined rectifying tower; a packing tower is provided at the upper part of the combined rectifying tower; an inner reflux condenser is provided at the top of the combined rectifying tower. The sodium hydroxide aqueous solution is added from a first plate of the plate tower; and 1,2-dichloroisobutane is added from the middle part of the plate tower. The method has the advantages that the raw material 1 and 1,2-dichloroisobutane is fully converted; the selectivity of the 2-methylallyl chloride is high.
