Description
Technical field
The present invention relates to a kind of organic acid glycidyl ester preparation method, belong to the organic synthesis field.
Background technology
Transesterification reaction between ester and the alcohol can be used dissimilar catalyzer.JP55011542 uses KOH as the catalyzer of condensation reaction, yet this strong alkaline substance can make Racemic glycidol in the short period of time polymerization take place, and produces potentiality danger such as blast.DE2423405 uses the stronger lithium methoxide of alkalescence as catalyzer, brings very big danger to aftertreatment.The use of weakly alkaline catalyzer also has report, has used potassium cyanide as catalyzer as DE2525026, and it can cause the appearance of addition by product, not only makes reaction process complicated, and product purity is reduced.JP55094381 has used the less Potassium ethanoate of toxicity as catalyzer, but in the still-process of aftertreatment, has significantly reduced the purity of product.Also have one piece of Japanese Patent to make catalyzer with triethylamine, use normal hexane that methyl alcohol is taken out of, obtain the very high product of purity.Triethylamine has suppressed the addition of methyl alcohol to methacrylic acid, has reduced the generation of by product.But triethylamine may be sneaked in the product, has influenced quality product, and the recovery of normal hexane is also pretty troublesome.JP55094379 has reported that also use N-Methylimidazole is as the Preparation of Catalyst glycidyl methacrylate.In transesterification reaction, by-product carbinol is that the existence by negative pressure separates from reaction system and removes, and the separation of target product is then realized by underpressure distillation.
Summary of the invention
The object of the invention is to provide the novel process of a kind of 4-of utilization Dimethylamino pyridine as Catalyst Production organic acid glycidyl ester, and synthesizes six kinds of fine-chemical intermediate compounds.The present invention utilizes the transesterification reaction principle, and single step reaction obtains needed product, simplifies technical process, reduces production costs.
The invention provides a kind of organic acid glycidyl ester preparation method, utilize the transesterification reaction of catalyst organic ester and Racemic glycidol, described organic ester is methyl acrylate, methyl benzoate, 4-nitrobenzoic acid methyl esters, 4-Iodobenzoic acid methyl esters, 4-acetylenylbenzene methyl-formiate or p-methoxycinnamic acid methyl esters; Described catalyzer is the 4-Dimethylamino pyridine.
Catalyzer in the transesterification reaction of the prior art is strong alkali catalyst, catalyzer in the transesterification reaction of the present invention is the 4-Dimethylamino pyridine, the 4-Dimethylamino pyridine is a kind of organic weak base, does not react with two keys, triple bond and iodine in the reactant, effectively suppresses the generation of side reaction.
The mass ratio of catalyzer of the present invention and organic ester is preferably 1:1~10.
The mass ratio of organic ester of the present invention and Racemic glycidol is preferably 1:1~10.
Preparation method of the present invention is for to join organic ester, Racemic glycidol, 4-Dimethylamino pyridine and stopper in the reactor, and the control temperature of reaction is 30~60 ℃, reaction 1~5h;
Described stopper is MEHQ.
Beneficial effect of the present invention is:
1. the 4-Dimethylamino pyridine is a kind of effective catalyst, and with catalyzer ratio of the prior art, in the identical reaction times, temperature of reaction obviously reduces; Identical temperature of reaction, the reaction times obviously shortens, and is beneficial to energy-saving and emission-reduction;
2. the 4-Dimethylamino pyridine is a kind of catalyzer of gentleness, can reduce the generation of side reaction;
3. the present invention utilizes transesterification reaction, and single step reaction obtains Chemicals, has simplified production process, has reduced production cost.
