Description
Technical field
It is used for cycloaddition reaction cyclic carbonate the present invention relates to a kind of cycloaddition reaction catalyst, more particularly to one kind
Catalyst and its preparation method and application
Background technology
Carbon dioxide is a kind of environment-friendly resource of carbon one, its rich reserves, nontoxic, non-combustible, cheap and easy to get and can
Circular regeneration.From the point of view of no matter being utilized from environmental protection or renewable resource, CO2Fixation and chemical conversion in terms of
Research is all significant.In organic synthesis, CO2The toxic compounds such as traditional CO and phosgene can partly be substituted to be carried out
The synthesis of organic carbonate, makrolon and urea etc., current these three compounds have been achieved with industrialized production.
Organic carbonate is the green chemical that a class has the characteristics such as higher boiling, low-steam pressure, low toxicity, has been widely used in
The multiple fields such as machine solvent, detergent, lithium battery electrolytes, fuel additive.Organic carbonate can be divided into linear carbonate
And cyclic carbonate.The industrial linear carbonate for having significant application value includes：Dimethyl carbonate (dimethyl
Carbonate, DMC), diphenyl carbonate (diphenyl carbonatem, DPC), methyl ethyl carbonate etc.；Cyclic carbonate bag
Include：Ethylene carbonate (ethylene carbonate, EC) and propene carbonate (propylene carbonate, PC) etc..Its
Middle cyclic carbonate (PC and EC) is widely used as the electrolyte of lithium battery, and with the fast development of mobile device, market is for height
The demand of quality cyclic carbonate is increasing (ten thousand tons/year of 40-50).In addition, PC is the raw material that ester-interchange method produces DMC,
It is the main application of current China PC.Therefore, with CO cheap and easy to get2The cyclic carbonate of high added value, tool are prepared for raw material

Hydrogen chloride is generated in journey, there is very strong corrosiveness to equipment, be eliminated in China；Alcoholysis of urea and vicinal diamines method are also located
In the laboratory research stage.At present, industrially using CO2Mainly pass through epoxides and CO for carboxyl source prepares cyclic carbonate2
Cycloaddition reaction.The mechanism of the reaction is to activate epoxides using electrophilic body, then under nucleopilic reagent concerted catalysis,
There is epoxides open loop, nucleophilic attack CO respectively2Molecule, cyclic carbonate ester products are obtained finally by Intra-molecular condensation
And complete catalyst regeneration (Chem.Soc.Rev.2012,41,1462).Therefore, the catalysts are provided simultaneously with nucleophilic and parent
Electric body.The catalytic reaction active component is mainly：Alkali metal salt, quaternary ammonium (Phosphonium) salt, organic base, basic anhydride, transition metal
