Production device and method for efficiently preparing ozonized oil

Abstract

The invention relates to a production device for efficiently preparing trioxidized oil. The production device comprises an ozonized oil reaction tank, wherein the upper part of the ozonized oil reaction tank is provided with a feed port; the lower part of the ozonized oil reaction tank is provided with a view port and a material receiving port; the left side of the ozonized oil reaction tank is connected with a temperature controller and a cooling water pump; the cooling water pump is connected with a cooling water tank; the upper end of the ozonized oil reaction tank is connected with an automatic exhaust valve; and the automatic exhaust valve is connected with an ozonized tail gas destructor. The invention also relates to a method for efficiently preparing trioxidized oil. The method uses vegetable oil, and is characterized in that the vegetable oil is vegetable oil with high alpha-linolenic acid content and is composed of one or both of perilla oil and flaxseed oil. The method has the advantages of controllable ozone oxidization process and more thorough oxidization, implements large-scale industrial production, enhances the ozone utilization efficiency, and enhances the stability of the ozone oxidization product.

Description

technical field [0001] The invention belongs to the technical field of preparation of ozonated oil, and in particular relates to a production device and method for efficiently preparing ozonated oil. Background technique [0002] As a very unstable gas, ozone can be synthesized into a stable ozonide by unsaturated fatty vegetable oil. Molecular reaction generates and releases stable hydrogen peroxide; however, there are two problems in the reaction between ozone and oil. One is that the reaction is very slow, and the other is that when ozone and vegetable oil are mixed and reacted, a large number of bubbles will be generated. Most of them were in the cold room in the early stage. Put the ozone gas directly into the vegetable oil for reaction, the bubbles disappear after 2 days, and later there is an improvement plan, which is to add a defoamer in the reaction column, but the production method of the bubbling method, the contact area between the gas and the vegetable oil is s...

[0002] As a very unstable gas, ozone can be synthesized into a stable ozonide by unsaturated fatty vegetable oil. Molecular reaction generates and releases stable hydrogen peroxide; however, there are two problems in the reaction between ozone and oil. One is that the reaction is very slow, and the other is that when ozone and vegetable oil are mixed and reacted, a large number of bubbles will be generated. Most of them were in the cold room in the early stage. Put the ozone gas directly into the vegetable oil for reaction, the bubbles disappear after 2 days, and later there is an improvement plan, which is to add a defoamer in the reaction column, but the production method of the bubbling method, the contact area between the gas and the vegetable oil is small, and the reaction is not good. Even, the operation is very troublesome, and it can produce tens of grams to several kilograms at a time. There is also a method of production using two-stage reactor stirring. Although the production can be carried out on a large scale, the problem of air bubbles has not been solved. Oil and gas The mass transfer efficiency is still very low, and what is more important is that these methods pay more attention to the dissolution of ozone in the oil, rather than the oxidation products after ozone oxidation of vegetable oil; in view of the above deficiencies, it is necessary to develop a more efficient oxidation reaction Rapid, more thorough, improve production efficiency, realize automation, large-scale production equipment and methods
