The invention discloses mesoporous ZSM-5 zeolite, a mesoporous ZSM-5 zeolite-loaded metal sulfide catalyst and an application. The synthesizing method of the mesoporous ZSM-5 zeolite comprises the following steps: (1) after uniformly mixing diallylamine and concentrated hydrochloric acid, adding dimethyl diallyl ammonium chloride, uniformly stirring and reacting for 1-6 hours at 60-120 DEG C, and cooling to obtain a template agent DMMC (Dimethylol Methyl Carbamate); (2) preparing acidified aluminum sulfate liquor by aluminum sulfate, concentrated sulfuric acid and water; (3) adding water into water glass, uniformly stirring, adding NaOH, adding the template agent DMMC after cooling to room temperature, continuously stirring for 2-5 hours, then adding the acidified aluminum sulfate liquor under stirring, and stirring for 2-8 hours to obtain a gel in a final state; (4) crystallizing the gel in the final state obtained in the step (3), filtering, drying and calcining to obtain the mesoporous ZSM-5 zeolite. The mesoporous ZSM-5 zeolite-loaded metal sulfide catalyst prepared by taking the mesoporous ZSM-5 zeolite as a carrier is applied to hydrodesulfurization of 4, 6-dimethyl dibenzothiophene and hydrocracking reaction of n-decane, thereby greatly improving the raw material conversion ratio.

The invention belongs to agricultural use antiseptic field. It discloses N-(2- substituted benzene group) N-methoxy methyl carbamate compound, its preparation and application. The compound has good fungicidal property, can be used to prevent and cure wheat powdery mildew, apple powdery mildew, wheat rust, green smut, corn southern leaf blight, and so on.

The invention discloses a preparation method of a diphenyl carbonate synthesis catalyst. The catalyst belongs to metal organic framework compounds. In the catalyst, an organic framework catalyst is formed by coordinating organic ligand trimesic acid and zinc-copper bimetal ions, and corrosion and pollution are avoided; the catalyst is used for catalyzing the synthesis of diphenyl carbonate from methyl carbamate and phenol, and the selectivity on a target product is relatively high; the catalyst has good stability, is easy to regenerate and can be repeatedly used for more than three times without obviously reducing the yield of diphenyl carbonate; the framework structure is basically kept complete and is easy to separate and recover; the application prospect is good.

The invention discloses an insect-resistant, corrosion-resistant, and mildew-resistant raw bamboo protective agent which comprises the following components: ammoniacal copper quaternary, N-2-benzimidazolyl methyl carbamate, and a penetrating agent, and also discloses processing technology of the raw bamboo protective agent, which comprises the following steps: performing bamboo joint punching processing of a fresh felled raw bamboo, naturally drying; putting the raw bamboo into a pressure impregnation tank, closing the tank door, turning on a vacuum pump to vacuumizing the impregnation tank; adding the raw bamboo protective agent till the impregnation tank is filled up with the vacuum pump being turned on; turning off the vacuum pump, turning on a pressure pump till the raw bamboo protective agent becomes saturated in the raw bamboo; releasing the pressure, discharging the protective agent in the impregnation tank. The purpose of the invention is to provide the raw bamboo protective agent which can simultaneously provide insect-resistant, corrosion-resistant, and mildew-resistant effects for raw bamboos, and also to provide the processing technology of the raw bamboo protective agent, which allows the protective agent to completely penetrate into the raw bamboo and thus to reach the effect of long-term raw bamboo protection without environment problems.

The invention discloses a sterilizing agent for mushrooms, which is prepared by mixing sodium dichloroisocyanurate, carbendazim, benzimidazole-2-methyl carbamate, glucose and boric acid. The sterilizing agent has reasonable formula, good sterilizing effect and low production cost and can be used for disinfecting and sterilizing in mushroom production.
