Abstract

A method for developing lube base oil with hydrogenated soybean oil under supercritical CO2 state solves the problem of food pollution in food processing industry due to lube leakage and spattering on machine. The method comprises the following steps: placing soybean oil in a high pressure kettle, placing the kettle in a water bath for reaction after supercritical hydrogenation, taking out the product after the reaction, and obtaining the lube base oil after centrifugation. Compared with the traditional hydrogenation method, the reaction time of supercritical hydrogenation is shortened by about 20min; the content of trans fatty acid is controlled and is decreased to less than 4% and is decreased by 9% compared with conventional method; and the content of saturated fatty acid in the soybean oil is increased so as to increase the resistance to oxidation. The method uses soybean oil as lube base oil to improve the edible components in the oil and reduce the toxic and side effect compared with common industrial lube. The detected peroxide value is 5.6 mmol / kg, the detected viscosity is 26 Pa.s, and the detected iodine value is 106.3gI2 / 100g.

Description

Technical field:

[0001] The present invention relates to a kind of in supercritical CO 2 A method for preparing lubricating oil base oil by hydrogenating soybean oil under state. Background technique:

[0002] In recent years, the issue of food safety has attracted the attention of people all over the world. Food safety emergencies have become a hidden danger to the society, and have brought huge economic losses to the country, and even destroyed international trade. Therefore, the importance of food safety cannot be ignored. With the advancement of human science and technology, the development of green and environmentally friendly renewable resources has been highly valued by people. Especially in the process of food processing, food safety has been seriously threatened due to splashing and leakage of lubricating oil on machinery.

[0003] At present, great progress has been made in the research on the development of green lubricating oil base oils from vegetable oils. ...
