Embodiment 1

[0025] Put 1g of NaOH into 50mL of methanol and stir magnetically. After the NaOH is completely dissolved, transfer it to a three-necked flask with a condensing reflux device, then add 15mL of cottonseed oil (refined), and place it in an oil bath with a stirring and temperature display function to stir. Heated to 55°C and reacted for 2h. Leave to stand for layering, separate the liquids, wash the upper layer solution with hot distilled water, and vacuum-dry to obtain cottonseed oil methyl ester. Add the catalyst Fe to the cottonseed oil methyl ester, then add 20 g of triethylsilane, raise the temperature to 180° C. for reflux hydrosilylation reaction, stop the reaction after 12 hours, and cool down. The solid catalyst is separated by centrifugation, and then the light components are removed by distillation under reduced pressure, and then centrifuged again to finally obtain the silicone cottonseed oil lubricating oil base oil.

Embodiment 2

[0028] Put 1g of KOH into 50mL of methanol and stir magnetically. After the KOH is completely dissolved, transfer it to a three-necked flask with a condensing reflux device, and then add 15mL of cottonseed oil and petroleum ether solution (after extracting cottonseed powder with two-liquid phase solvent petroleum ether + methanol) , solid-liquid separation, static layering, the upper layer is cottonseed oil and petroleum ether solution), placed in an oil bath with a stirring temperature display function, stirred and heated to 55 ° C, and reacted for 2 hours. Leave to stand for layering, separate the liquids, wash the upper layer solution with hot distilled water, and vacuum-dry to obtain cottonseed oil methyl ester. Add the catalyst Zn to the cottonseed oil methyl ester, then add 10 g of trimethylsilane, raise the temperature to 170° C. to carry out the reflux hydrosilylation reaction, and stop the reaction after 12 hours of reaction. The solid catalyst is separated by centrif...

Embodiment 3

[0030] Put 1g of NaOH into 50mL of methanol and stir magnetically. After the NaOH is completely dissolved, transfer it to a three-necked flask with a condensing reflux device, then add 15mL of refined cottonseed oil (buy cottonseed oil in barrels), and place it in a thermostat with a stirring and temperature display function. Stir and heat in an oil bath to 55°C, and react for 2 hours. Leave to stand for layering, separate the liquids, wash the upper layer solution with hot distilled water, and vacuum-dry to obtain cottonseed oil methyl ester. Add the catalyst Ni to the cottonseed oil methyl ester, then add 10 g of diethylchlorosilane, raise the temperature to 160° C. to carry out the reflux hydrosilylation reaction, and stop the reaction after 12 hours of reaction. The solid catalyst is separated by centrifugation, and then the light components are removed by distillation under reduced pressure, and then centrifuged again to finally obtain the silicone cottonseed oil lubricat...

Abstract

The invention discloses a method for preparing an organic silicon cottonseed oil-based lubricating oil base oil. The method comprises the following steps: carrying out methyl esterification on cottonseed oil under the catalysis of an alkali, mixing and stirring an obtained cottonseed oil methyl ester and a catalyst (according to a certain ratio), adding organosilicon, heating to a reaction temperature, and carrying out hydrosilation reaction; after reacting for a period of time, stopping heating, cooling, centrifugally separating out the solid catalyst, distilling to remove light components, and centrifugally separating again to finally obtain the organic silicon cottonseed oil-based lubricating oil base oil. Cotton seed oil (or cotton seeds) is used as a raw material and is wide in source, easy to obtain, high in quality and low in price, cost is greatly reduced, steps are simple and easy to operate, product performance is good, and the market prospect is wide.

Description

technical field [0001] The invention relates to the field of preparation of green bio-based lubricating oil base oils, in particular to a process for preparing organic silicon cottonseed oil-based lubricating oil base oils by using cottonseed oil, a raw material with a wide range of sources, high quality and low price, and organic silicon. It is a method for preparing silicone cottonseed oil-based lubricating oil base oil. Background technique [0002] Lubricating oil is composed of base oil and additives. Base oil is the main component of lubricating oil (70-99%), which determines the basic properties of lubricating oil. Traditional mineral base oils generally use petroleum as raw materials, which are cheap and can meet the lubrication requirements between machines. However, mineral-based lubricants cannot be biodegraded or have poor biodegradability, causing certain pressure on the environment. In addition, during the use of lubricating oil, due to various reasons, its l...
