The production equipment of the methyl ethyl carbonate has the advantages that the structural design is reasonable, the continuous feeding reaction and the production process can be realized, the throughput can reach up to ten thousand tonnage, the one-time non-intermittent completion of the methyl ethyl carbonate from generation to the product canning can be realized, and the conversion rate of the methyl ethyl carbonate can be effectively ensured.
Description
Technical field
The utility model belongs to the technology of preparing of Methyl ethyl carbonate, is specifically related to a kind of equipment that is used for the carbonate production by transesterification methyl ethyl ester.
Background technology
Methyl ethyl carbonate is a kind of asymmetric carbonic ether, at aspects such as organic synthesis, medicine, agricultural chemicals, solvent, additives extensive use is arranged.Because the viscosity of Methyl ethyl carbonate is little, specific inductivity is big, to the solvability chamber of lithium salts, is used for the organic electrolyte of lithium ion battery, can improve energy density, loading capacity and the low temperature use properties of battery.
The synthetic method of Methyl ethyl carbonate mainly contains phosgenation, oxidative carbonylation method and ester-interchange method, it is three operational paths of raw material that ester-interchange method has methylcarbonate and ethanol, diethyl carbonate and methyl alcohol and methylcarbonate and diethyl carbonate, is the industrialization most popular method for preparing Methyl ethyl carbonate at present.To adopt methylcarbonate and ethanol is the device of raw material production Methyl ethyl carbonate for existing, and can only to pass through rhythmic reaction, batch fractionating and methyl ethyl carbonate ester conversion rate low for Methyl ethyl carbonate in original production technique; Methyl ethyl carbonate needs can't satisfy the needs of existing high yield preparation of industrialization Methyl ethyl carbonate through multiple tracks operation at intermittence and device systems from producing product turnover jar.
The utility model content
The utility model provides a kind of reasonable in design, can realize the production unit of the Methyl ethyl carbonate of continuously feeding reaction and production technique, and unit capacity reaches ton.It can realize making Methyl ethyl carbonate to advance a jar disposable nothing and intermittently finish from being generated to product, and can effectively ensure the transformation efficiency of Methyl ethyl carbonate.
The technical scheme that the utility model adopted is as follows:
A kind of production unit of Methyl ethyl carbonate, it is characterized in that described equipment comprises a reaction tower, this reaction tower is connected with and separates the heating-type feeder, described reaction tower also is connected with the discharging pipeline, this tapping channel is provided with rectifying still by fractionation by distillation device connection, and rectifying still connects product discharging pipeline.
In one embodiment, described separation heating-type feeder is connected setting with the middle part conversion zone of described reaction tower, and described separate type heating feeder comprises an interchanger and the charging opening that is provided with the interchanger heat exchange.
In one embodiment, described separation heating-type feeder is independent two groups of feeders that are provided with, and is respectively methylcarbonate heating-type feeder and ethanol heating-type feeder.
In another embodiment, the top of described reaction tower is provided with the catalyzer charging opening.
In the embodiment, described rectifying still is two groups of the series connection setting again, and each rectifying still is connected setting by return line with described reactor respectively.
The production unit of this Methyl ethyl carbonate has been broken through the traditional fixed pattern notion of methylcarbonate transformation efficiency, adopted in methylcarbonate and alcoholic acid step of reaction and to have separated the heating-type feeder and respectively methylcarbonate and ethanol are heated the back charging, the full separation heat exchanging charging method of this original creation can reduce the condition that Methyl ethyl carbonate transforms to diethyl carbonate fully, and improve methylcarbonate and alcoholic acid speed of response simultaneously, effectively guaranteed the selectivity of this reaction.
The beneficial effects of the utility model are that the production unit reasonable in design of this Methyl ethyl carbonate can realize continuously feeding reaction and production technique, and unit capacity reaches ton.It can realize making Methyl ethyl carbonate to advance a jar disposable nothing and intermittently finish from being generated to product, and can effectively ensure the transformation efficiency of Methyl ethyl carbonate.
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Description of drawings
Fig. 1 is the composition structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, the production unit of this Methyl ethyl carbonate comprises a reaction tower 11, this reaction tower is connected with and separates the heating-type feeder, and separating the heating-type feeder is independent two groups of feeders that are provided with, and is respectively methylcarbonate heating-type feeder 13 and ethanol heating-type feeder 14.The top of reaction tower is provided with catalyzer charging opening 12.Reaction tower also is connected with the discharging pipeline, and this tapping channel is provided with rectifying still by a fractionation by distillation device 15 connections, and rectifying still connects product discharging pipeline.Two separation heating-type feeders are connected setting with the middle part conversion zone of reaction tower, and separate type heating feeder comprises an interchanger and the charging opening that is provided with the interchanger heat exchange.Rectifying still is two groups of the series connection setting, and each rectifying still 16,17 is connected setting by return line with described reactor respectively.
The production unit of this Methyl ethyl carbonate can be used for the production of ton methyl ethyl carbonate ester apparatus continous-stable, the contriver produces Methyl ethyl carbonate processing parameter bag through the ton single stage method that this equipment has been developed in effort in many ways, comprises the energy material consumption amount of each cat head still temperature, pressure, flow, the every data of liquid level and each tower; Comprise that also Methyl ethyl carbonate internal control production quality control technical indicator is like the content in the following table one.
