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.

The present invention relates to a parallel synthesis method and synthesizer of a compound library, and more specifically provides a parallel synthesis method and synthesizer of a compound library, which uniformly distribute a first reactant and perform independent reactions in separate spaces, and since it is possible to confirm the results for various reaction variables at once, the synthesis time of the compound library can be reduced with a high synthesis yield of the product.

Methods and devices are disclosed for reacting and separating components. An elongated vessel has a microchannel heat pipe with a hollow space inside the microchannel heat pipe being surrounded by inner walls. A feed stream and a reactant stream are passed into the hollow space, the reactant reacting, resulting in a product stream. A first end of the microchannel heat pipe is heated and an opposite end of the microchannel heat pipe is cooled, producing a gas phase and a liquid phase in reflux. The liquid phase attaches to the inner walls via capillary forces and the vapor phase makes up the balance of the hollow space. The reflux separates components in the product stream, a first portion passing out of a first end of the heat pipe as a liquid stream and a second portion passing out of a second end of the heat pipe as a vapor stream.

Conversion of heavy fossil hydrocarbons (HFH) to a variety of value-added chemicals and/or fuels can be enhanced using microwave (MW) and/or radio-frequency (RE) energy. Variations of reactants, process parameters, and reactor design can significantly influence the relative distribution of chemicals and fuels generated as the product. In one example, a system for flash microwave conversion of HFH includes a source concentrating microwave or RF energy in a reaction zone having a pressure greater than 0.9 atm, a continuous feed having HFH and a process gas passing through the reaction zone, a HFH-to-liquids catalyst contacting the HFH in at least the reaction zone, and dielectric discharges within the reaction zone. The HFH and the catalyst have a residence time in the reaction zone of less than 30 seconds. In some instances, a plasma can form in or near the reaction zone.

A continuous phase solution is injected into the first inlet; and a second inlet is defined in the first portion at a second height different from the second height. A dispersed phase solution is injected into the second inlet. A merging volume is defined in the second portion and is defined at third height equal to either the first height and the second height, or has a value therebetween. The continuous phase solution and the dispersed phase solution are merged in the merging volume, wherein fine particles are formed. A first micro-channel and a second micro-channel branching from the merging volume communicates with the first inlet and the second inlet, respectively.
