Problems solved by technology

[0004] In the above-mentioned sorbic acid manufacturing process, if the crotonaldehyde cannot be completely reacted, the crotonaldehyde needs to be separated from the sorbic acid polyester, and it will also cause too high acidity in the condensation process
However, the existing technology cannot meet the complete reaction of ketene and crotonaldehyde, which leads to the increase of energy consumption and cost caused by the separation process.
Moreover, the existing reactor cannot switch between continuous reaction and batch reaction, which is not conducive to the complete reaction of reactants.

Embodiment Construction

[0021] Such as figure 1 As shown, the present invention provides a multi-tower combined reactor 100 in a specific embodiment. The multi-tower combined reactor 100 includes a crotonaldehyde feed tank 101, three reactor groups (not marked), a ketene gas input pipeline (not marked), a gas output pipeline (not marked) and one Root liquid output pipeline (not marked).

[0022] The crotonaldehyde feed tank 101 is a crotonaldehyde raw material storage tank of the multi-tower combined reactor 100, and is used to continuously or intermittently input the crotonaldehyde raw material into the multi-tower combined reactor 100. The crotonaldehyde feed tank 131 includes at least one crotonaldehyde outlet 131.

[0023] Each reactor group includes a polymerization tower, a polymerization kettle and a four-way controller. The polymerization tower is a reactor for preliminary polymerization of crotonaldehyde and ketene, and the polymerization vessel is a reactor for further reaction of crotonaldehy...

Abstract

The invention relates to a multi-tower combined reactor. In the invention, a plurality of reactor groups including a polymerization tower and a polymerization kettle are connected with one another byfour-way controllers; inlets at ends of the reactor groups are added with crotonic aldehyde, and inlets at other ends thereof are added with ketene, thus being capable of converting a continuous reaction state to an intermittent reaction state according to the proceeding conditions of the reaction simultaneously when the crotonic aldehyde and the ketene react under a reverse flow direction state,so that the crotonic aldehyde can be completely reacted, and the process complexity and increased cost brought by the separation of crotonic aldehyde and sorbic acid polyester are avoided.

Description

Technical field [0001] The invention relates to a reactor, in particular to a multi-tower combined reactor. Background technique [0002] With the improvement of people's living standards, the requirements for food quality and food safety also increase. Among them, food preservatives are an important aspect related to food quality and food safety. Sorbic acid or potassium sorbate can effectively inhibit the activity of molds, yeasts and aerobic bacteria. It can also prevent the growth and reproduction of harmful microorganisms such as botulinum, staphylococcus and salmonella. However, it is resistant to anaerobic spores and Beneficial microorganisms such as Lactobacillus acida are almost ineffective. Moreover, its effect of inhibiting the development of microorganisms is stronger than that of sterilization, which can effectively extend the storage time of food and maintain the original flavor. Its antiseptic effect is 5 to 10 times that of sodium benzoate. At present, sorbic ...
