Abstract: A method is disclosed for maintaining a volumetric gas to liquid ratio in a segmented gas/liquid flow along a reactor of monolithic catalyst beds in series. The present invention includes the steps of: initiating the segmented gas/liquid flow at a first end of the reactor by introducing feed liquid and feed gas both at a predetermined volume and a predetermined flow rate; injecting an additional amount of gas at least once into any of the spaces between catalyst beds; and combining the segments of the segmented gas/liquid flow at a second end of the reactor. The injection of gas is controlled such that the segmented gas/liquid flow can be maintained near or at the Taylor regime.

Abstract: A method of preparing dinitromethane salts usable as intermediate products and starting material for production of explosives and propellants. Substituted 1,2-diazoles, 1,2,4-triazoles or 1,3-diazines, such as barbituric acid, are nitrated to obtain a gem-dinitro group on a carbon atom in the heterocyclic ring. The product is hydrolysed to split off dinitromethane which is neutralised with a neutralising agent to obtain a corresponding salt of dinitromethane.

Abstract: The present disclosure provides a method for preparing an organophosphorus degrading enzyme based multifunctional catalyst and an organophosphorus degrading enzyme based multifunctional catalyst and use thereof. In the present disclosure, the preparation method includes: directly adding a composite yolk-shell-structured nanomaterial into a crude enzyme solution of organophosphorus degrading enzyme with an affinity tag, and mixing, to obtain a mixture, and then subjecting the mixture to a separation, to obtain an organophosphorus degrading enzyme based multifunctional catalyst. According to the present disclosure, the method for preparing an organophosphorus degrading enzyme based multifunctional catalyst is simple in operation, and has a low cost; the multifunctional catalyst prepared by the same has low requirement for the purity of enzyme, support of which could be directionally binded with enzyme, and could be used for detecting an organophosphorus pesticide, and also for a cascade degradation of an organophosphorus pesticide. The final product p-aminophenol has important application value.
