Method for preparing MCT oil by utilizing coconut oil

Abstract

The invention belongs to the field of special oil synthesis, and specifically relates to a method for preparing MCT oil by utilizing coconut oil. Mixed fatty acid and glycerin water are obtained through the hydrolysis of coconut oil; caprylic acid and capric acid are obtained by processing the mixed fatty acid, and glycerin is obtained by processing the glycerin water; and MCT oil is obtained by utilizing the caprylic acid and capric acid to react with the glycerin. The method only takes the coconut oil as a raw material and synthesizes the MCT oil through effective components obtained throughthe hydrolysis of the coconut oil; and the produced MCT oil is low in cost, reasonable in yield and guaranteed in quality.

[0001] The invention belongs to the field of special oil synthesis, and in particular relates to a method for preparing MCT oil from coconut oil. Background technique

[0002] MCT oil is medium carbon chain fatty acid glycerides. MCT oil is a colorless transparent liquid at room temperature, with a slight fragrance of coconut oil. It is a derivative of coconut oil or palm oil. Because of its short carbon chain, it has a relatively small molecular weight and good water solubility. It is a rare energy and Water-miscible oil body, which is not harmful to human skin and other tissues, has a low melting point (-15°C), high boiling point, low density, and low viscosity, which is about 50% of ordinary vegetable oil. The unsaturated fatty acid in MCT oil is extremely low, and its iodine value does not exceed 0.5. Compared with vegetable oil and animal oil, MCT oil is the best anti-oxidation oil at present, with excellent physical and chemical properties, and it is m...

[0027] 1) Hydrolysis of coconut oil: Add soft water to refined coconut oil (preheated to 90-95°C), the mass ratio of oil to water is 1:1.5, add methanesulfonic acid, the amount added is 5% of the weight of coconut oil; then add 98wt% Concentrated sulfuric acid, the addition amount is 10% of coconut oil weight. The hydrolysis temperature is controlled at 80-85°C. When the hydrolysis time reaches 10 hours, suspend heating, and after standing for 40 minutes, put the glycerin water into the water distribution tank. Then repeat the process of adding water, adding acid, adding catalyst, and performing secondary hydrolysis. The operation is the same as that of the primary hydrolysis. Then wash the fatty acid twice with soft water (preheated to 80-85°C), and the amount of water added is 30-40% of the oil. After the fatty acid is degassed, put it into the crude fatty acid tank for fractionation; the hydrolysis rate after the second hydrolysis is not less than 92%.
