Description
Technical field
The present invention relates to a kind of preparation methods, and in particular to a kind of preparation method of glycine betaine methyl ester hydrochloride.Belonging to
Learn synthesis technical field.
Background technology
Beet alkali hydrochlorate is a kind of quaternary alkaloid, possesses excellent bioactivity, in medicine, pesticide, feed
The industries such as additive and cosmetics have a wide range of applications, and glycine betaine methyl ester hydrochloride be prepare beet alkali hydrochlorate must not
The key intermediate species that can lack, its preparation directly affect the preparation of beet alkali hydrochlorate.
The chemical synthesis of beet alkali hydrochlorate, can according to the type of alkali mostly using monoxone and trimethylamine as base stock
To be subdivided into the calcium method technique different with two class of sodium method.The calcium method technique of existing literature report is substantially all using monoxone, hydrogen
Calcium oxide and trimethylamine reaction prepare glycine betaine methyl ester hydrochloride, are then acidified the synthesis strategy for preparing beet alkali hydrochlorate again,
But during monoxone and calcium hydroxide reaction prepare calcium chloroacetate, monoxone hydrolytic side reactions inevitably occur
Hydroxyacetic acid is generated, trimethylamine is excessive, and discharge amount of exhaust gas is big, easily causes environmental pollution, and energy consumption is high.Sodium method technique is main
Monoxone, sodium hydroxide and trimethylamine are raw material, although raw material is easy to get, technique chlorine in the preparation process of sodium chloroacetate
Acetolysis side reaction is more, causes the yield of the technique only 86% or so, and the production cycle of technique is long, the utilization rate of equipment and
Turnover rate is relatively low, and sodium chloride residual is more in the product prepared, influences product quality.Therefore, there is an urgent need to develop a kind of high
Imitate energy saving, environmental-friendly glycine betaine methyl ester hydrochloride preparation method.
Invention content
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of preparation of glycine betaine methyl ester hydrochloride
Method is to prepare glycine betaine methyl ester hydrochloride by excessive methyl chloroacetate and trimethylamine quaternization reaction, avoids chloroethene
Sour first ester hydrolysis, realizes the Quantitative yield of trimethylamine, reduces the generation of exhaust gas, and with short production cycle, simple for process,
Low energy consumption.
To achieve the above object, the present invention uses following technical proposals:
A kind of preparation method of glycine betaine methyl ester hydrochloride, comprises the concrete steps that:Methyl chloroacetate is added into reaction bulb, so
After be passed through front three amine gas and reacted, after reaction, air-distillation deviates from unreacted methyl chloroacetate to get glycine betaine
Methyl ester hydrochloride;Wherein, the mol ratio of methyl chloroacetate and trimethylamine is 1.2~2:1, reaction equation is as follows:
Preferably, reaction temperature is 25~40 DEG C.
Preferably, the reaction time is 1~4 hour.
Preferably, the unreacted methyl chloroacetate cycle is anti-for preparing for glycine betaine methyl ester hydrochloride next time
It answers.
Beneficial effects of the present invention:
The present invention carries out quaternization reaction to prepare glycine betaine methyl esters by excessive methyl chloroacetate and front three amine gas
Hydrochloride, after reaction air-distillation go out unreacted methyl chloroacetate, obtain product glycine betaine methyl ester hydrochloride, the chlorine of abjection
Methyl acetate recycle utilizes.
The preparation method of the present invention, realizes the Quantitative yield of trimethylamine, avoids the hydrolysis of methyl chloroacetate, and product is received
Rate reaches 99% or more, stable quality, simple for process, low energy consumption, and it is easy fundamentally to overcome monoxone in traditional soda technique
Hydrolysis, conversion ratio are low, and trimethylamine is excessive, and discharge amount of exhaust gas is big, easily causes the key technology difficulty of environmental pollution.
