Embodiment 1

[0013] Weigh 20 milliliters of absolute ethanol, 220 grams of castor oil, and 8 grams of tetrabutyl titanate into the reaction kettle, react for 8 hours under normal pressure and 40°C, and then distill the ethanol out in a vacuum distillation device , the pressure is -0.1MPa~-0.001MPa, the temperature is 25~60°C, and the modified vegetable oil can be obtained.

Embodiment 2

[0015] Weigh 20 ml of absolute ethanol, add 220 g of peanut oil, and 5 g of tetrabutyl titanate into the reaction kettle, react for 6 hours under normal pressure and 60°C, and then distill the ethanol out in a vacuum distillation device, namely Modified vegetable oils are available.

Embodiment 3

[0017] Reactive distillation conditions were used.

[0018] Weigh 20 milliliters of absolute ethanol, 220 grams of castor oil, and 8 grams of tetrabutyl titanate into the reaction kettle of the reaction distillation device. Under normal pressure and 60 ° C, the reaction is refluxed for 6 hours, and then the reflux is stopped and vacuumized. , Distill the ethanol under reduced pressure to obtain modified vegetable oil.

Abstract

The invention provides modified vegetable oil which is obtained by the following method: mixing alcohol and tetrabutyl titanate with the vegetable oil; carrying out reaction at the temperature of 20 to 80 DEG C; after the reaction, separating the remnant alcohol to obtain the modified vegetable oil. Compared with the unmodified one, the modified vegetable oil greatly improves oxidation stability and extreme pressure anti-wear, and broadens the application prospect of the vegetable oils in various fields.

Description

technical field [0001] The invention relates to a modified vegetable oil. Background technique [0002] The vast majority of traditional lubricating oils use mineral oil as the base oil. In some special occasions, such as metal processing oil, chain saw oil, outboard two-stroke engine oil and open gear oil and other open systems or disposable circulation systems, Lubricating oil will inevitably be discharged directly into the environment due to use, leakage, etc. However, mineral-based lubricating oils have poor biodegradability in the natural environment, accumulate in the environment and cause pollution to the ecological environment. Some developed countries have established strict laws to control the discharge of lubricating oil. For example, in Germany, all open chain saw oil must use biodegradable lubricating oil. Major oil companies in the world have started to develop environmentally friendly green lubricating oils to replace traditional mineral-based lubricating oi...
