Abstract
The utility model discloses a continuous ethyl hexanoate esterification reaction kettle, which comprises an esterification kettle, wherein the right upper end of the esterification kettle is provided with a discharge port, the left lower end of the esterification kettle is provided with a feeding port, the left upper end of the esterification kettle is provided with a heat conduction oil outlet, and the right lower end of the esterification kettle is provided with a heat conduction oil inlet. The continuous ethyl hexanoate esterification kettle is characterized in that a raw material mixing tank and a metering pump are also arranged outside the esterification kettle, a stirring device is arranged in the raw material mixing tank, and an outlet of the metering pump is communicated with the feeding port of the esterification kettle; a reaction elbow is arranged in the esterification kettle, and two ends of the reaction elbow are respectively connected with the feeding port and the discharging port. According to the continuous ethyl hexanoate esterification reaction kettle, mixed raw materials in the raw material mixing tank are continuously and accurately pumped into the esterification kettle by the metering pump, the reaction materials fully contact and react in the stainless steel reaction elbow, not only can the esterification kettle be prevented from being corroded by an acid catalyst and the like, but also continuous, stable and automatic esterification reaction is realized, and thus the esterification efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of esterifying kettle, is specifically related to a kind of ethyl hexanoate continuous esterification still.
Background technology
At present; The preparation method of tradition ethyl hexanoate adopts caproic acid and ethanol under heating condition, directly to carry out esterification mostly; Charging aperture is arranged on their mostly adopt, down the batch (-type) reaction kettle of the esterification of discharging opening arranged; Efficient is very low, can not realize continuous and automatic large-scale production, haves much room for improvement to be the continous way reaction kettle of the esterification.
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The utility model content
The technical problem that the utility model will solve is: be directed to the deficiency of prior art, provide a kind of in esterifying kettle, be provided with the stainless steel reaction bend pipe continuously, the ethyl hexanoate continuous esterification still of stablizing, react completely, carrying out automatically.
