Description
Technical field
The utility model belongs to a kind of chemical mechanical equipment field, is specifically related to the novel material feeding unit in a kind of carbonic ether workshop.
Background technology
Usually the raw material used in the esterification reaction has liquid acid and solid acid two class, high concentrated acid adopts airtight tubing feed in raw material or add grease phase with after alcohol dilution usually, but these two kinds of modes all exist disadvantage: directly add high concentrated acid and grease can be caused to occur that carbonization, coking etc. destroy oil component phenomenon because local contact concentrated acid; The mode throwing material after being first diluted to finite concentration with alcohol then avoids local grease and contacts with concentrated acid and produce the phenomenon such as carbonization, coking, but the process hazard of dilution is extremely high, concentrated acid can produce a large amount of heat with alcohol when coordinating, control difficulty height during cooperation, it is easy to that security incident occurs, and diluted acid after coordinating is extremely strong to the corrodibility of equipment, therefore the material of the device of condiment and conveying, pipeline, pump valve there is extremely high requirement; The throwing material of solid acid class mainly adopts manual type directly to drop into reactor at present, the defect of this kind of feeding mode is: throws every time and expects that the throwing material all needing to open reactor covers again property and throws material, and throwing in material process, gas in reactor can be emerged from dog-house, therefore there is certain potential safety hazard, and air can be polluteed.
Methyl ethyl carbonate EMC is the Chemicals of the high added value of rising in recent years, and it is a kind of asymmetric carbonic ether, has extensive use in organic synthesis, medicine, agricultural chemicals, solvent, additive etc. May be used for many Disposal degree batteries, such as lithium metal battery, as the cosolvent of its non-aqueous electrolyte, it is possible to improve the performance of battery, as improved its energy density, increase discharge capability, improve stability in use and security, and have methyl and ethyl due to it simultaneously, have the characteristic of methylcarbonate DMC, diethyl carbonate DEC concurrently, also it is the solvent of extraordinary spices and intermediate, therefore has broad application prospects.
The synthetic method of current EMC mainly contains phosgenation, oxidative carbonylation and ester-interchange method, and wherein ester-interchange method is the EMC synthetic method comparatively commonly used. Wherein ester-interchange method mainly contains three kinds of approach, is respectively DMC and DEC transesterify, DEC and methyl alcohol transesterify, DMC and ethanol transesterify. Wherein DMC and ethanol transesterify synthesis EMC is reversible reaction, the catalyzer DMC of this reaction and ethanol are the catalyzer being relatively easy to get, and resultant methyl alcohol can also as the catalyzer producing DMC, this reaction product toxicity is little, reaction process is without " three wastes ", facility investment is little, and technique is simple, production purity height. But for adopting methylcarbonate and ethanol to be the device of Catalyst Production Methyl ethyl carbonate in prior art, in original production technique, Methyl ethyl carbonate can only pass through rhythmic reaction, batch fractionating, and Methyl ethyl carbonate low conversion rate; Methyl ethyl carbonate passes in and out tank from production to product to be needed to meet the needs of existing high yield preparation of industrialization Methyl ethyl carbonate through too much road interval operation and device systems.
