Description

Technical Field

[0001] The utility model relates to the technical field of oleic acid production, in particular to an acidolysis device for oleic acid production. Background Art

[0002] Industrial oleic acid is made from vegetable oil soap stock through saponification, acid hydrolysis, washing, vacuum distillation, and freeze pressing. Pure oleic acid is a colorless oily liquid, and industrial products are yellow to red oily liquids with the smell of lard. It is insoluble in water, but soluble in organic solvents such as ethanol and gasoline. It has the general chemical properties of organic carboxylic acids and the chemical characteristics of unsaturated double bonds. Acid hydrolysis is an extraction process using acid as the extraction liquid. The process in which organic matter is decomposed by acid or the molecular weight of polymers is reduced by acid is also called acid hydrolysis.

[0003] At present, when the vegetable oil soap stock raw material of oleic acid is used as the raw material for oleic acid production, the enzymatic hydrolyzate is usually put into the reactor from the feeding tube at the top of the reactor, and then the vegetable oil soap stock raw material is put into the reactor from the feeding tube at the top of the acidolysis reactor. The stirring structure in the acidolysis reactor will evenly stir the acidolysis liquid and the vegetable oil soap stock raw material for acidolysis reaction. However, this commonly used acidolysis mixing method of stirring and contacting only after entering the acidolysis reactor is inefficient and cannot achieve the contact reaction between the acidolysis liquid and the vegetable oil soap stock raw material before entering the reactor, thereby affecting the acidolysis efficiency of oleic acid production. For this reason, we propose an acidolysis device for oleic acid production. Utility Model Content
