Description
Technical field
The utility model relates to chemical industry equipment field, particularly relates to a kind of device for the production of propyl butyrate.
Background technology
Propyl butyrate, mainly, as solvent, chromatography standard substance, is also widely used in flavor formulation.Under normal temperature state, be a kind of colourless liquid that has fruit fragrance.Industrial organic synthesis intermediate, solvent, the spices of can be used as.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 ℃, while reacting in reactor, heating-up temperature need to reach more than 180 ℃, traditional reactor adopts electrothermal tube-conduction oil socket joint heating reactor, due to the sealing problem not yet solution so far of oil circuit piping, and adopt optional equipment to occupy factory building space greatly and increase operating cost.
Summary of the invention
The utility model, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of and can effectively prevent that propyl alcohol from leaking and the device of the production propyl butyrate of temp. controllable, and the conversion ratio of ester can reach more than 90%.
The technical scheme solving the problems of the technologies described above is as follows:
Device for the production 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 one 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, on pipeline between esterification kettle and condenser, be provided with blocking valve, on the housing of condenser, be connected with the first conduit and the second conduit, one end of the 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 utility model compared with prior art, have the following advantages: reactor cost is lower, simple in structure, energy consumption is low, account for little, safe and reliable, the easy temperature adjustment in factory building space and thermal conversion efficiency high, and reaction conversion ratio can be up to more than 90%, and efficiently solve the leakage of propyl alcohol, be convenient to promote the use of.
