Brief Introduction
The chemical formula of 1,8-diazabicyclo [5.4.0] undecane-7-ene (DBU) is c9h16n2. It is used as catalyst, ligand and non nucleophilic base in organic synthesis. DBU can be isolated from a sponge called niphates digitalis and is therefore also considered an alkaloid. DBU can be used as curing agent of epoxy resin; It can also be used as a protective agent in the synthesis of cephalosporin; DBU is also used in the purification of fullerene-c60 (DBU reacts with fullerenes with C70 or more carbon numbers, but does not interact with C60); DBU was also used as catalyst in the synthesis of polyurethane. DBU is also used as a catalyst in the reaction of alicyclic and aliphatic isocyanates.

Brief Introduction
Potassium tert butyl alcohol is an important organic base, which is more basic than potassium hydroxide. Because of the induction effect of (CH3) 3Co trimethyl group, it has stronger basicity and activity than other potassium alcohols, so it is a good catalyst. In addition, as a strong base, potassium TERT butoxide is widely used in chemical industry, medicine, pesticide and other organic synthesis, such as transesterification, condensation, rearrangement, polymerization, ring opening and the production of heavy metal orthoesters. It can be used to catalyze Michael addition, pinacol rearrangement and Ramberg Backlund rearrangement; Potassium TERT butoxide can be used as a condensation agent to catalyze Darzens condensation and STOBBE condensation; It is also the most effective base in the traditional alkoxide haloform reaction for the formation of dihalogenated carbenes. Therefore, potassium tert butyl alcohol is more and more favored by chemical, pharmaceutical, pesticide and other industries. Potassium TERT butoxide is widely used, so there is a great demand for high purity potassium TERT butoxide at home and abroad. However, the production cost of potassium tert butyl alcohol is higher than that of other alkali metal alkoxides, and the production technology needs to be improved.
