Description
Technical field
The present invention relates to field of chemical equipment, particularly relate to a kind of device for the production of propyl butyrate.
Background technology
Propyl butyrate, is mainly used as solvent, chromatography standard substance, is also widely used in flavor formulation.A kind of colourless liquid having fruit aroma under normal temperature state.Industrially can be used as organic synthesis intermediate, solvent, spices.But industrial esterification reaction equipment complex structure, operating cost is high, and alcohols easily leaks, and the productive rate of ester is lower, generally 50%-60%.Its boiling point is 143 DEG C, when reacting in a kettle., heating-up temperature needs to reach more than 180 DEG C, traditional reactor adopts electrothermal tube-conduction oil socket joint heating reactor, because the sealing problem of oil circuit piping not yet solves so far, and it is large and increase operating cost to adopt optional equipment to occupy hall space.
Summary of the invention
The present invention is in order to overcome the deficiency of above-mentioned technical problem, and provide a kind of propyl alcohol that can effectively prevent and leak and the device of the production propyl butyrate of temp. controllable, the conversion ratio of ester can reach more than 90%.
The technical scheme solved the problems of the technologies described above is as follows:
For the production of the device of propyl butyrate, comprise esterification kettle, the outlet of esterification kettle upper gas is connected with one end of pipeline, the pipeline other end connects condenser, esterification kettle is jacket type structure, the inside of jacket type structure is provided with electric heater, electric heater outside is provided with insulating barrier, esterification kettle side is provided with temperature sensor, temperature sensor is connected with temperature controller, the input of temperature controller is connected with power supply, its output is connected with electric heater, pipeline between esterification kettle and condenser is provided with blocking valve, the housing of condenser is connected with the first conduit and the second conduit, one end of first conduit is provided with vacuum extractor.
Further, the port of export of the second described conduit is provided with receiving hopper.
Further, the first described conduit and the second conduit are respectively arranged with the first valve and the second valve.
Further, described electric heater is electrothermal tube, heating wire or electric hot plate.
The present invention compared with prior art, have the following advantages: reactor cost is lower, structure is simple, energy consumption is low, account for little, safe and reliable, the easy temperature adjustment of hall space and thermal conversion efficiency high, and reaction conversion ratio up to more than 90%, and can efficiently solve the leakage of propyl alcohol, is convenient to promote the use of.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
