Abstract
It is a kind of be mutually hydrogenated with for cis-butenedioic anhydride water be directly synthesized succinic acid catalyst be carbon coating ambrose alloy Cu Ni/Al2O3@C catalysts, wherein carbon content are 1 7wt%, and nickel content is 10 17wt%, and copper content is 2 8wt%, and remaining is Al2O3.Catalyst of the invention has high activity, high selectivity, good stability, long lifespan, prepares simple advantage.
Description
Technical field
The invention belongs to catalyst technical field, and in particular to one kind is directly synthesized fourth two for being catalyzed cis-butenedioic anhydride aqueous solution hydrogenation
Catalyst of acid and its preparation method and application.
Research background
Succinic acid can be used as excellent performance sensitising agent, and the important intermediate of pigment, such as dimethyl succinate are a kind of important
Light stabilizer (be used for vinyl house), and diisopropyl ester amber acid synthetic dyestuff process does not almost pollute, and produces pigment (vapour
Car metallic paint) have the advantages that degree of staining is high, bright in colour, weather resistance is high.Main application fields are broadly divided into five classes：The
One class is surfactant, cleaning agent, additive and foaming agent；Equations of The Second Kind is in food processing, as acid；3rd class
It is to be produced as medicine intermediate, can be used to produce sulfa drug, Va, B6, hemostatic and cortisone derivative；4th class is ion
Corrosion and spot corrosion in chelating agent, such as electroplating industry；5th class is most promising field, and it is biodegradable modeling
The primary raw material of material poly butylene succinate (PBS).Poly butylene succinate (PBS) is a kind of new excellent performance
Biological degradation plastics, compared with traditional biodegradable plastics, with fusing point it is high, heat resistance is good, mechanical performance is excellent,
The advantage of relative low price (being the 1/3 of existing biodegradable plastic).
The production method of succinic acid mainly has：Biological fermentation process, electrochemical reducing and cis-butenedioic anhydride catalytic hydrogenation method.Wherein,
Cis-butenedioic anhydride catalytic hydrogenation method has the advantages that technological process is simple and convenient to operate, operating cost is low, high income, good product quality, quilt
It is considered most potential succinic acid production method, the study hotspot as recent domestic.
Maleic anhydride hydrogenation synthesizing succinic acid can be divided into has solvent with solvent-free two kinds of process routes.Solvent-free maleic anhydride hydrogenation refers to
In the presence of a catalyst, directly with hydrogen there is hydrogenation reaction generation succinic anhydride in the cis-butenedioic anhydride of molten state.Patent CN
92100554.7 and CN 92103481.4 is disclosed under a kind of condition of no solvent, using Raney's nickel catalyst to molten condition
The method that maleic anhydride hydrogenation prepares succinic anhydride.Catalyst is fed intake with cis-butenedioic anhydride with certain proportion, hydrogen in kettle is kept in hydrogenation process
Atmospheric pressure is constant, using the method separating catalyst and product of heat filtering at the end of reaction.Using the method, succinic anhydride is most
High yield can reach 90% and 96%.Because maleic anhydride hydrogenation synthesizing succinic acid acid anhydride is strong exothermal reaction (Δ H=-128KJ/
Mol), the reaction heat for being produced in hydrogenation process easily makes reactant/product polycondensation for carbon species high, is covered in catalyst table
Face is present in final products, influences the yield and purity of target product succinic anhydride.Subsequently with respect to the research of maleic anhydride hydrogenation
Carry out in organic solvent more.Such as CN1453066A, CN 101891718A, CN 101502802B, CN 102311332B, CN
The patents such as 102229587B use in tetrahydrofuran, toluene, 1,4- dioxane, acetone or gamma-butyrolacton one or two with
Upper is catalysis maleic anhydride hydrogenation synthesizing succinic acid acid anhydride in the presence of solvent catalyst.By gained reaction solution through rectifying (or crystallization dry
It is dry), hydrolysis, crystallization, succinic acid is obtained after drying.
If electing the solvent of maleic anhydride hydrogenation as water, the use of organic solvent is on the one hand avoided, can significantly reduced organic
Solvent uses the harm of environmental pollution；On the other hand, it is, along acid, hydrogenation synthesis to be selected through C=C keys that cis-butenedioic anhydride meets water electrode facile hydrolysis

Yield；Furthermore, gained reaction solution crystallisation by cooling obtains final product succinic acid after drying, and reaction process step is greatly reduced, and improves
Economical in reaction.Have the advantages that operating process is simple, energy consumption is low, environmental benefit good.The B of Chinese patent CN 101844976 with
One or more in the cis-butenedioic anhydride aqueous solution, the fumaric acid aqueous solution or aqueous maleic acid are raw material, in silica, titanium dioxide
Carry out on Ni, Pd-Co, Pt-Fe, Ni-Ir, Ni-Rh, Ni-Ru catalyst of zirconium, activated carbon, titanium oxide or carborundum load and add
Hydrogen is reacted, and has obtained the aqueous solution of succinic acid, and succinic acid product is obtained after crystallisation by cooling, drying.The method adopts water as molten
Agent, it is, along acid, active component to be rushed from carrier surface along acid strong, the easily corrosion catalyst carrier of acid that cis-butenedioic anhydride meets water electrode facile hydrolysis
Brush down, reduce the service life of catalyst.There is a problem of that catalyst activity component is easily lost in during long time running.Patent
The B of CN 102417445 then with the aqueous solution of maleate as raw material it is hydrogenated after obtain the succinate aqueous solution, will obtain fourth
Diacid is acidified, separate after obtain succinic acid.Corrosion of the strong acid reaction solution to catalyst is this method reduce, but be increased
Follow-up acidification step, reaction process complex steps.
