Using cotton seed oil as the raw material, an ammonolysis reaction was carried out under alkaline catalysis to prepare cotton seed oil fatty amide (CFA).
Synthesis of Cotton Seed Oil Fatty Amide
Cotton seed oil was used as the raw material, and CFA was synthesized using an alkali-catalyzed ammonolysis method. The typical reaction was carried out in a glass reactor consisting of a four-necked round-bottom flask (1000 mL). The reactor was equipped with a speed-adjustable electric motor-driven stirrer and a temperature sensor to control the overall reaction temperature. Additionally, the reactor had a condenser and an inlet neck for dropping in the raw materials and maintaining an inert atmosphere by purging with N2 gas as required. The entire assembly was placed in a constant-temperature oil bath with a special arrangement to accurately maintain the temperature within ±5 °C of the desired temperature.
Calculated amounts of diethanolamine (0.32 mol) and sodium methoxide (0.007 mol) were added to the reactor, and the mixture was heated to 80 °C for 15 minutes under continuous stirring. Over the next 60 minutes of continuous stirring, cotton seed oil (0.1 mol) was added dropwise to the reaction mixture, and the temperature was gradually increased to 120 °C. The reaction was continued for 3 hours at 120 °C under controlled stirring. The progress of the reaction was monitored using TLC, and the solubility of the reaction mixture in methanol was determined. After reaching the desired solubility in methanol, the product was dissolved in diethyl ether and then washed with a 15% aqueous solution. The ether layer was separated, and the solvent was evaporated in a rotary vacuum evaporator to obtain the CFA.

Plant oils have been used as lubricants for many years due to their excellent lubricity, high flash point, good viscosity-temperature characteristics, and compatibility with mineral oils and additive molecules. However, their major drawback is their high pour point, poor thermal stability, and poor oxidative stability, as they contain unsaturated double bonds in their structure. These limitations have restricted their practical application in the lubricant field. Epoxidation is considered one of the promising chemical modification methods for unsaturated double bonds.
Synthesis of Epoxidized Cotton Seed Oil
Epoxidation of cotton seed oil was carried out using hydrogen peroxide as the epoxidizing agent and formic acid and phosphoric acid as catalysts to prepare epoxidized cotton seed oil (ECSO). The epoxidation reaction was carried out in a four-necked round-bottom flask equipped with a mechanical stirrer, a thermometer, and a condenser. A solution of hydrogen peroxide (130 mL) and phosphoric acid (0.5 mL) in a constant-pressure dropping funnel was added slowly to the flask containing CSO (100 g) and formic acid (0.66 mol, 25 mL). During the reaction, the temperature of the reaction mixture was maintained at 45-50 °C. After the reaction was complete, the inorganic acids were completely removed by dissolving the reaction mixture in petroleum ether and washing it with hot water (50 °C) three times. The final product, ECSO, was obtained after vacuum distillation to remove the petroleum ether.
