Description

The method for preparing the antigravity system for hydrocyanation and isomerization
Technical field
The present invention relates to the method for the antigravity system for producing the hydrocyanation for butadiene or allyl acetonitrile.More properly Say, the present invention also relates to be used for the hydrocyanation of butadiene or allyl acetonitrile using the antigravity system prepared in one-step reaction, and Method for 2- methyl -3- butene nitriles to be isomerized into 3 pentene nitrile.
Background technology
The hydrocyanation catalyst system of the known hydrocyanation for being specifically used for butadiene or allyl acetonitrile in art.Definitely Say, it is adaptable to which the hydrocyanation of 1,3-butadiene is to form system of the follow-up hydrocyanation of allyl acetonitrile and allyl acetonitrile to form adiponitrile It is commercially known in important nylon synthesis field.
Such hydrocyanation reaction is complexed in the zero-valent nickel catalyst with single tooth or double tooth organophosphor ligands, such as phosphite ester Carried out in the presence of thing.There are the various methods for becoming known for preparing the zero valent nickel complex with single tooth organophosphor ligand, including It is described in those in US 3,903,120 and US 4,416,825.In US 3,903,120, Ni [P (OAr)3]4Type complex compound By making elemental nickel and list tooth part P (OAr)3At a temperature in the range of 0 DEG C to 150 DEG C, containing list as catalyst React and prepare in the presence of the halogen of the derivative of tooth part.US 4,416,825 is described by the amount control relative to single tooth part Reaction temperature processed and reacted and prepared comprising having single tooth organophosphor in the presence of chlorion and organic nitrile (such as adiponitrile) The continuation method of the hydrocyanation catalyst of the zero valent nickel complex of part.
There are some nickel catalysis that can be used for manufacture with single tooth and double tooth organophosphor ligands (exactly phosphite ester) The method of agent complex compound.A kind of method is double (1,5- the cyclo-octadiene) [Ni (COD) of nickel2] anti-with organic phosphite part Should.But, the method is due to Ni (COD)2High cost and be poorly efficient and uneconomic and therefore can not be in commercial size Upper production.Another method is using Dehydrated nickel chloride and in-situ reducing of the zinc metal in the presence of organic phosphite part.This Program is effective for single tooth and double tooth organic phosphite parts, but causes one mole of the nickel complex formation of every mole of formation Zinc chloride.Method is also difficult to carry out in business method, because it needs accurate measurement to go out to enter two kinds of solids of reactor, and Dehydrated nickel chloride is not easy to obtain on a commercial scale.
The another way for preparing the Raney nickel complex compound with organic phosphite part is using catalytic amount Ar2PCl make the nickel by powder of fine crushing directly with organic phosphite ligand reaction, wherein Ar is aryloxy, such as cresols, such as Disclosed in US 3,847,959.The method is effective for single tooth organic phosphite part using commercially available nickel by powder, But it is not useable for preparing double tooth zero-valent nickel organic phosphite complex compounds due to lacking reactivity.
US 8,815,186 is open directly to prepare double tooth zeroth order organic phosphorous acid Raney nickel complex compounds from nickel metal powder. But, nickel metal powder must be prepared by wherein disclosed ad hoc approach.One shortcoming of the method is anti-using height for it Answering property spontaneous combustion nickel by powder, the powder must be disposed in the case of in the absence of oxygen.In addition, it is necessary to such as ZnCl2Louis Acid is to be reacted, if catalyst is used subsequently to the hydrocyanation of butadiene or 2- methyl -3- butene nitriles is isomerized to 3- penta Alkene nitrile, then the acid of trace is harmful.
The another method for preparing double tooth zeroth order organic phosphorous acid Raney nickel complex compounds is EP 1 414 567 theme, institute State the two-stage process that patent description prepares the double teeth of mixing and single tooth zeroth order organic phosphorous acid Raney nickel complex compound.Method is comprising extremely Few two steps.First, zero-valent nickel and P (OR)3(wherein " R " is organic group) reacts to form the first system.Then, in second step In, the first system with double tooth organic phosphite ligand reactions with produce including single tooth material (i.e. comprising with single P (OR)3 The catalyst of the nickel of complexing) and double tooth material (i.e. comprising only with double tooth organic phosphite parts or P (OR)3It is organic with double teeth Phosphite ester ligand mixture complexing nickel catalyst) zeroth order organic phosphorous acid Raney nickel complex compound.This two-step method Having the shortcomings that can not be commercial, because catalyst complex can not possibly be reclaimed in single standard extraction procedures for further Use.Recovery reuses most important in continuation method and is economically for reusing in business method for catalyst It is required.In addition, it would be desirable to separated before catalyst synthesis step is repeated single tooth material (i.e. comprising with single P (OR)3Network The catalyst of the nickel of conjunction) and double tooth material (i.e. comprising only with double tooth organic phosphite parts or P (OR)3With the organic Asia of double teeth The catalyst of the nickel of the mixture complexing of phosphate part) to repeat two-stage process, it is by extremely difficult (even if not can not possibly). EP 1 414 567 also discloses a kind of method, wherein Ni (COD)2, between phosphorous acid/toluene ester and double tooth organic phosphites are matched somebody with somebody Body reacts in single step.One-step program is by Ni (COD)2Shortcoming described above too expensive is stranded for commercial mass production Disturb.
An object of the invention is to solve one or more in these problems.
