نمک فنل DBU

DBU phenol salt is an organic base salt, in which DBU (1, 8-دیازابیسیکلو [5.4.0]undec-7-ene) یک پایه قوی است, and phenol is a commonly used organic acid. DBU phenol salts are formed by the reaction of DBU and phenol. DBU phenol salts have many applications in organic synthesis. It can be used as a catalyst for the ester dehydration reaction, which converts the ester to ether or acid and generates the corresponding DBU phenol salt. علاوه بر این, it can also be used as a catalyst for condensation reaction and participate in the condensation reaction of organic matter. علاوه بر این, it can also be used in acylation reactions to promote the acylation of substances.

کاربرد

1. DBU phenol salt is used as a catalyst for the production of polyurethane and other chemical products, such as ammonia and dichloroethane in its presence to react to piperazine, is an excellent dehydrating agent, epoxy resin hardener, anti-rust agent, and can also prepare advanced corrosion inhibitors. در حال حاضر, it is widely used in the production of semi-synthetic antibiotics of cephalosporin. It is also used in organic synthesis reactions and semi-synthetic antimicrobials.

2. Can be used for dehydrogenation halogenation reaction to form olefin amidine; Esterification of carboxylic acid with alkyl halide; Alkylation and acylation of active methylene compounds.

3. It can also be used to synthesize α, β-unsaturated ketone, ester amide, ammonia salt and other organic compounds.
