The steel wire rope (6) is connected to one end of the force gauge (8) via the D shackle (8) at a folding position thereof, and the other end of the force gauge (9) is connected to a hook (10) of the lever hoist (12) via the D shackle (8). The lever hoist (12) is suspended from an overhead crane. The forge gauge (9) is connected to the computer (7) via a lead wire. Further provided is a method for measuring a braking torque of a hoist.

Abstract

N2 reaction and a cyclization reaction. Namely, o-fluorinated aryl-N,N-dimethyl-formamidine and primary amine are subjected to an cyclization by a one-pot reaction, wherein a fluorine atom is substituted by an amino, and then dimethylamine is eliminated, thus forming the product. The method does not require the use of any metal catalyst and/or any toxic reagent, and has a specific selectivity. No isomer exists in the reaction product.

Abstract

Disclosed are a benzoimidazole compound and a preparation method therefor, wherein the preparation method involves synthesizing various substituted benzoimidazoles by means of SN2 and a cyclization reaction, namely, by replacing a fluorine atom with amine in a one pot reaction, from corresponding o-fluorinated aryl-N,N-dimethyl formamidine and primary amine, and then eliminating products resulting from dimethylamine cyclization. The method does not require the use of any metal catalyst and/or any toxic reagent, and has a specific selectivity, and no isomer is produced in the reaction product.
