Abstract
The invention discloses a new method for preparing 1, 3-dihydroxyacetone from glycerol, which comprises the following steps: (1) acetalation reaction, which is to perform acetalation reaction of the glycerol and benzaldehyde in the presence of a water-carrying agent and under the action of an acid catalyst A so as to obtain glycerol benzaldehyde acetal ester having a structure as shown in the formula (I); (2) oxidation reaction, which is to oxidize the glycerol benzaldehyde acetal ester in an organic solvent and under the action of an oxidizer so as to obtain 5-carbonyl-2-phenyl -1, 3-dioxanehaving a structure as shown in the formula (II); and (3) hydrolysis reaction, which is to hydrolyze the obtained 5-carbonyl-2-phenyl -1, 3-dioxane in the presence of an acid catalyst B so as to prepare a 1, 3-dihydroxyacetone dimer having a structure as shown in the formula (III). The synthetic route of the method uses the glycerin as a raw material, thus both the selectivity and the yield are higher than that by a method of direct oxidation, the target product is simple and convenient to separate, and the product purity can reach 99 percent; and compared with the prior art, the synthetic route of the method has stronger market competitiveness.
Description
(1) technical field
The present invention relates to a kind of 1, the preparation method of 3-otan.
(2) background technology
In recent years along with grease chemical article expanding production continuously of biofuel particularly; Seriously drug on the market to cause its by-product glycerin; Price glides significantly, is that the exploitation that raw material carries out derived product can well solve the superfluous problem of glycerine with glycerine, can reduce the production cost of biofuel again.1, (DHA dihydroxyacetone), is a kind of important medicine intermediate, industrial chemicals and foodstuff additive, the composition of makeup sun-screening agent to the 3-otan.Also can be used as a kind of Anti-virus agent,, can kill 51%~100% ewcastle disease virus as in the egg embryo culture; The anti-corrosive fresh-keeping that also can be used for fruits and vegetables, fishery products, meat product; Still have many other purposes among positive research and development.
At present, 1, the industrialized process for preparing of 3-otan comparative maturity mainly is enzyme method for making (J.Ferment Technol, 1979,57 (3): 227), promptly with glycerine dehydrogenation enzyme glycerine is oxidized to 1,3-otan.But the existence of mushroom has limited the concentration range of glycerine, makes the yield of enzyme method for making be difficult to improve, and because the more influence of by product makes whole aftertreatment technology become numerous and diverse, time consumption and energy consumption, production cost is high.Because DHA is of many uses, market capacity is big, and excessive as biological diesel oil byproduct glycerin, and the research high yield, to purify be that the novel method of feedstock production DHA has great importance easily with glycerine.
The external chemical synthesis glycerine converting of using is existing a lot of patents of otan and bibliographical information, but mainly is that direct catalytic oxidation prepares otan.Because glycerine is polyol, adopt the direct oxidation route, the transformation efficiency of glycerine and the productive rate of otan are all lower.The result of study that Kimura.etal announces shows; During the glycerine oxidation, in the Pt catalyzer, add Bi, can greatly improve selectivity secondary alcohol; When catalyzer is 1%Bi-5%Pt/C; In one batch reaction productive rate of otan be 20% (Appl.Catal.A, 1993,96:217).When catalyzer is 0.6%Bi-3%Pt when loading on the gac, be 40% a mixed bed conversion rate, the productive rate of DHA be 30% (German Patent, DE4228487).Under acidic conditions, and add a certain amount of auxiliary agent, use the Pt catalyzer, the transformation efficiency of glycerine reaches as high as 70%, but the maximum yield that transformation of glycerol forms otan for only 37% (Catalysis Today, 2000,57:127).This is up to now, and the glycerine oxidation prepares the highest data of otan productive rate.The direct catalyzed oxidation glycerine method of domestic report, catalyzer is 9%Pt-5%Bi/C, 55 ℃ of temperature of reaction; 50 hours reaction times; The selectivity of DHA has only 40.2%, and the transformation efficiency of glycerine is 81.6%, but the productive rate of DHA is merely 32.8% (Hainan Normal University's journal (natural science edition); 2007,20 (3)).Can find out the direct oxidation of glycerine, only depend on and improve the shortcoming that catalyzer is difficult to change long reaction time, poor selectivity.
(3) summary of the invention
It is feedstock production 1 with glycerine that the technical problem that the present invention will solve is to provide a kind of, the method for 3-otan, and it is simple that this preparing method's transformation efficiency is high, selectivity is good, product separates purification.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of 1, the preparation method of 3-otan, said preparation method is following: (1) acetalation: in the presence of the band aqua, acetalation takes place and obtains structure suc as formula the glycerine phenyl aldehyde acetal ether shown in (I) in glycerine and phenyl aldehyde under acid catalyst A effect; (2) oxidizing reaction: the glycerine phenyl aldehyde acetal ether of gained under the oxygenant effect the oxidized structure that obtains suc as formula the 5-carbonyl-2-phenyl-1 shown in (II), 3-dioxane; (3) hydrolysis reaction: the hydrolysis in the presence of acid catalyst B of gained 5-carbonyl-2-phenyl-1,3-dioxane makes structure suc as formula 1 shown in (III), 3-otan dimer.
Reaction equation is following:
Each reactions step in the face of above-mentioned preparation method is elaborated down.
The said acetalation of step of the present invention (1) specifically can be carried out according to following steps: glycerine, phenyl aldehyde, acid catalyst A and band aqua are joined in the reaction vessel; Be warming up to 100~130 ℃ of reactions 1~6 hour under stirring; After reaction finished, aldolization liquid obtained structure suc as formula the glycerine phenyl aldehyde acetal ether shown in (I) through separation and purification; The amount of substance ratio that feeds intake of said glycerine, phenyl aldehyde is 1:1.0~1.5, and the consumption of said acid catalyst A is 1~10% of a glycerine weight.
Further; The acid catalyst A that uses in the said acetalation can be liquid acid or solid acid; Be preferably the vitriol oil, p-methyl benzenesulfonic acid or strongly acidic cation-exchange, said strongly acidic cation-exchange can be selected strongly acidic cation-exchanges such as CD550, D072.
The band aqua that uses in the said acetalation is preferably benzene or toluene, more preferably benzene.The volumetric usage of said band aqua is 3~5 times of glycerine volume.
Separation purification method described in the said acetalation can be according to carrying out as follows: said aldolization liquid through washing, dry, reclaim the band aqua after in the mixing solutions of benzene and sherwood oil in-9.0~-25.0 ℃ of crystallizations, obtain glycerine phenyl aldehyde acetal ether.
