Description
Technical field
The present invention relates to method and the special-purpose catalyst thereof of a kind of spirit catalytic of cinnamaldehyde or Oleum Cinnamomi preparing benzaldehyde by oxidizing.
Background technology
Phenyl aldehyde is only second to vanillin food grade,1000.000000ine mesh, is second largest spices of world's consumption, has very widely in industries such as food, healthcare products, makeup and medicine intermediates and uses.According to statistics, at present the whole world is once being only natural benzaldehyde for food flavor(ing) spices up to more than 7000 tons, and the demand of natural benzaldehyde is also in increase year by year.
Preparation natural benzaldehyde most study is phenylacrolein alkaline water solution at present.Due to phenylacrolein and water immiscible, be difficult between reactant contact and cause the yield of product greatly to reduce.In order to improve the solubleness of phenylacrolein in water, introducing phase-transfer catalyst or tensio-active agent is a kind of effective means, but the side reaction that phase-transfer catalyst exists is many, separates the poisonous shortcomings such as phase-transfer catalyst difficulty.The propositions such as Ji Hongbing utilize cyclodextrin compound, make solubilizing agent (CN101037384) or hydroxypropyl-b-cyclodextrin is promotor (200910192485.8) as beta-cyclodextrin, phenylacrolein alkaline hydrolysis prepares the preparation method of phenyl aldehyde, but the method exists the yield of long reaction time, phenyl aldehyde low, the defectives such as cyclodextrin cost recovery height.
alkaline hydrolysis prepares the deficiency that phenyl aldehyde exists based on phenylacrolein, Ji Hongbing etc. propose again " a kind of method of cyclodextrin spirit catalytic of cinnamaldehyde or Oleum Cinnamomi preparing benzaldehyde by oxidizing " (2010181273.2), the method is made catalyzer with epoxy chloropropane and beta-cyclodextrin cross-linked polymkeric substance, water insoluble and the organic solvent of this catalyzer, solve preferably the recovery problem of cyclodextrin, the molecule inclusion of cyclodextrin and the essential property of recognition capability have been kept simultaneously, can form inclusion complex with guest molecule, has good catalytic activity, also has certain mechanical stability, the simultaneous reactions mild condition, yield is high.But this catalyzer consumption in reaction process is large, easy water absorption and swelling, and under the effect of oxygenant, easily become tiny particle, and conglomerate has greatly affected the catalytic activity of this catalyzer.
Summary of the invention
The object of the present invention is to provide method and the special-purpose effective catalyst thereof of a kind of spirit catalytic of cinnamaldehyde or Oleum Cinnamomi preparing benzaldehyde by oxidizing.
This catalyzer is cyclodextrin-chitosan polymer with general formula (I) structure, n=2.5～4 wherein, described cyclodextrin is b-cyclodextrin or derivatives thereof, its chemical structural formula as shown in general formula (II),
General formula (I)
General formula (II)

This catalyzer can prepare as follows:
With the chitosan (deacetylation is 95%) of acetic acid dissolving with glutaraldehyde at 40-60
oUnder the condition of C stirring reaction 1-2 hour, filter, obtain chitosan resin after drying, resin and propylene oxide are reacted in the blending agent of NaOH solution and dimethyl sulfoxide (DMSO), and then at alkaline, 60-80
oWith b-cyclodextrin stirring reaction 4-8 hour, wash, be drying to obtain the cyclodextrin of different polymerization degree-chitosan polymer catalyzer under the condition of C, wherein the polymerization degree n value is determined by the mol ratio of chitosan and glutaraldehyde.
The phenyl aldehyde preparation method that the present invention carries out, that raw meat oil of bay or phenylacrolein are carried out catalytic oxidation under the effect of catalyzer and oxygenant thereof, used catalyst is cyclodextrin-chitosan polymer of the present invention, take water as solvent, adding mass concentration is 1%～90%, a kind of oxygenant of doing in preferred 1 ~ 30% hydrogen peroxide, clorox or tertbutyl peroxide, the mass ratio of catalyzer and raw material is 1:5～5:1, is 30 ~ 90 in temperature of reaction
oSpirit catalytic of cinnamaldehyde or Oleum Cinnamomi preparing benzaldehyde by oxidizing under the condition of C, reaction finish by obtaining phenyl aldehyde after organic extractant extraction, the concentrated purification.Reaction equation of the present invention:
In the method for above-mentioned spirit catalytic of cinnamaldehyde or Oleum Cinnamomi preparing benzaldehyde by oxidizing, the mass ratio of preferred catalyzer and raw material is 1:1～2:1, and preferred temperature of reaction is 50 ~ 80
oC, described organic extractant are esters solvent, methyl alcohol, acetone or acetonitrile, and preferred organic extractant is ethyl acetate, methyl acetate and butylacetate.
Chitosan is to couple together the direct-connected polysaccharide of formation (Isosorbide-5-Nitrae)-2-amino-2-deoxidation-β-D-Glucose with β-(Isosorbide-5-Nitrae) glycosidic link after the chitin deacetylase base, shows good biological activity and adsorptivity.Cyclodextrin be a class by the D-glucopyranose units by the macrocylc compound that α-Isosorbide-5-Nitrae-glycosidic link joins end to end and forms, hydrophilic outer wall and hydrophobic cavity are arranged, can form inclusion complex with hydrophobic molecule.With cyclodextrin immobilized to the chitosan resulting polymkeric substance, the envelope recognition performance and the catalytic activity that had both had cyclodextrin, the characteristic such as biological degradability, biocompatibility, nontoxicity of chitosan is arranged again, and have the characteristics such as good physical strength, stability and chemical adjustability.
The envelope recognition performance of the cyclodextrin that the present invention adopts-existing cyclodextrin of chitosan polymer catalyzer has again the biological activity of chitosan and the dual nature of absorption property.Therefore this catalyzer is when spirit catalytic of cinnamaldehyde or Oleum Cinnamomi preparing benzaldehyde by oxidizing, catalytic activity is greatly improved, catalyst levels also greatly reduces, and to effectively reducing the production cost of phenyl aldehyde, realizes that the industrialization of phenyl aldehyde has extremely important meaning.Polymkeric substance is easily degraded simultaneously, and is little to environmental influence, also really realizes the characteristics of green non-pollution.
