An ammonia production method is a method of producing ammonia from nitrogen molecule using electron supplied from a power supply in the presence of a complex and a proton source. The complex used is, for example, a molybdenum complex (1) that is carried on Merrifield resin. The proton source used is an electrolyte membrane, a solution used in a cathode tank, or both the electrolyte membrane and the solution used in the cathode tank:

Disclosed by the present invention is a method for preparing a reactive sealant resin, the method comprising: (1) under the action of an alkali catalyst, polymerizing a hydroxyl-containing initiator with an epoxy compound to obtain a polyether polyol; (2) adding an alkoxide reagent and a halogenated end-capping agent containing a double bond to the polyether polyol obtained in step (1) for reaction, so as to obtain a crude double-bonded polyether product, and refining the crude product to obtain a modified polyether product; and (3) subjecting the modified polyether and hydrogen-containing silane to silane end-capping reaction under the action of a hydrosilylation catalyst, so as to obtain the target product, i.e., a reactive sealant resin. The resin has excellent properties as well as good adhesion and paintability.

A field of asymmetric catalytic synthesis, and in particular a preparation method for a high optical indoxacarb intermediate includes reacting 5-chloro-2-methoxycarbonyl-1-indanone ester (or indanone ester for short) with an oxidizing agent in the presence of a chiral Zr-salen polymer to obtain an indoxacarb intermediate (2S)-5-chloro-2,3-dihydro-2-hydroxy-1-oxo-1H-indole-2-carboxylic acid methyl ester. The yield is stabilized between 86% and 90%, and the S-enantiomer content is up to 99%. Such catalyst can replace catalysts such as cinchonine, and greatly increase the content of the effective S-enantiomer of the indoxacarb, so that the content of the hydroxyl intermediate S-enantiomer of the indoxacarb is raised from 75% to 99% or more. In addition, the chiral Zr-salen polymer catalyst is recycled without retreatment, and can be recycled at least 5 times or more, greatly reducing the production cost and laying a foundation for the industrial production of high quality indoxacarb.
