Problems solved by technology

Epidemiological surveys in the population show that certain human cancers, such as gastric cancer, esophageal cancer, liver cancer, colon cancer and bladder cancer, may be related to nitrosamines; CMEA (cocoic acid monoethanolamide) is solid at room temperature, When using this product, it needs to be dissolved in the system by heating, which is inconvenient to use. During the heating process, it brings disadvantages such as large energy consumption and unfriendly environment; EO is a gaseous state synthesized by oxidation of ethylene gas.

Embodiment 1

[0042] A kind of fatty acid glyceride, its specific preparation steps are as follows:

[0043] Under the condition of feeding nitrogen, firstly, 200g of glycerin, 282g of octanoic acid, 115g of capric acid and 2g of p-toluenesulfonic acid were added into the reactor, the temperature was raised to 130°C, and the reaction was carried out for 6 hours, and the water formed by the reaction was distilled off. Continue to feed nitrogen, under reduced pressure conditions with a vacuum degree of -0.05MPa, maintain the temperature at 130°C, react for 1 hour, and completely separate the water generated in the reaction again to obtain the light yellow product fatty acid glyceride;

[0044] The obtained fatty acid glyceride is used as a thickener for daily washing products and cosmetics, and is designated as thickener 1.

Embodiment 2

[0046] A kind of fatty acid glyceride, its specific preparation steps are as follows:

[0047] Under the condition of nitrogen gas, first add 200g glycerin, 184g methyl caprylate, 182g methyl caprate, 10g methyl laurate and 2g phosphoric acid into the reactor, raise the temperature to 150°C, react for 1 hour, and distill off the reaction product of water. Continue to feed nitrogen, raise the temperature to 170°C under reduced pressure conditions with a vacuum degree of -0.07MPa, react for 6 hours, and completely separate the water generated in the reaction again to obtain the light yellow product fatty acid glyceride;

[0048]The obtained fatty acid glyceride is used as a thickener for daily washing products and cosmetics, and is designated as thickener 2.

Embodiment 3

[0050] A kind of fatty acid glyceride, its specific preparation steps are as follows:

[0051] Under the condition of nitrogen gas, firstly add 200g glycerin, 297g ethyl caprylate, 422g ethyl caprate, 10g ethyl myristate and 2g sodium hydroxide into the reactor, raise the temperature to 160°C, react for 2 hours, distill The water formed by the reaction was removed. Continue to feed nitrogen, raise the temperature to 180°C under reduced pressure conditions with a vacuum degree of -0.07MPa, react for 3 hours, and completely separate the water generated in the reaction again to obtain the light yellow product fatty acid glyceride;

[0052] The obtained fatty acid glyceride is used as a thickener for daily washing products and cosmetics, and is designated as thickener 3.

Abstract

The invention belongs to the technical field of fine chemical engineering, and discloses fatty glyceride as well as a preparation method and an application thereof. The fatty glyceride is prepared from the following components by mole percent: 20-60mol% of glycerinum, 5-50mol% of component A, 1-50mol% of component B and 0-10mol% of component C, wherein the component A is octanoic acid, methyl caprylate or ethyl caprylate, the component B is decanoic acid, methyl decanoate or ethyl decanoate and the component C is saturated fatty acid, fatty acid methyl ester or fatty acid ethyl ester with 12-16 carbon atoms. The preparation method comprises the following steps: carrying out a reaction on the components and a catalyst at a normal pressure at 130-180 DEG C for 1-6 hours in nitrogen; then, carrying out a decompression reaction at 130-210 DEG C for 1-6 hours and dehydrating to obtain the fatty glyceride. The fatty glyceride obtained has an extremely good synergic tackifying effect and good foaming characteristic and foaming behavior and can be used as a thickener for synthesis of daily detergent products and cosmetics.

Description

technical field [0001] The invention belongs to the fields of oleochemical technology and fine chemical technology, and specifically relates to a fatty acid glyceride and its preparation method and application. Background technique [0002] At present, fatty acid glycerides are widely used in food additives, and are widely used in food industry, cosmetics and pharmaceutical products. Fatty acid glycerides have been used as food emulsifiers to form a series of products, and have played an important role in improving food quality, processing performance and production efficiency. In addition to making oil and water emulsify and disperse uniformly, this kind of food additives also has multiple purposes such as foaming, defoaming, viscosity reduction and fresh-keeping. In cosmetic applications, these products mainly play the role of emollient and emulsifying. [0003] Among synthetic detergents, various surfactants such as cationic surfactants, anionic surfactants, amphoteric ...
