Embodiment Construction

[0010] This specific embodiment adopts the following technical solutions: its manufacturing steps are as follows:

[0011] 1. Take a certain proportion of glycerin and oleic acid, wherein the molar ratio of glycerin and oleic acid is 2.3-3.2:1, and the optimal ratio is 2.6-3:1;

[0012] Two, take the catalyzer of total amount 0.1%-1%, optimal dose is 0.3%-0.6%, described catalyzer is p-toluenesulfonic acid, solid super strong acid, self-made catalyst etc., wherein most preferably is self-made catalyzer;

[0013] 3. Add the above-mentioned glycerin, oleic acid and catalyst into the reactor, raise the temperature of the reactor, keep the reaction temperature at 140-220°C, the optimum reaction temperature is 190-220°C, and the reaction time is 4-8 hours, and The best reaction time is 6-8 hours;

[0014] 4. After the reaction is over, use a vacuum dehydrator to vacuum dehydrate the reactant until the acid value reaches the standard. The standard is as follows: the appearance is l...

Abstract

The invention provides a preparation process of triolein, relating to the technical field of chemical engineering. The preparation process comprises the following steps: weighing glycerol and oleic acid of which a certain molar ratio is (2.3-3.2):1; weighing a catalyst the amount of which is 0.1%-1% of the total weight, wherein the catalyst is p-toluene sulphonic acid, solid super strong acid, self-made catalyst and the like; adding glycerol, oleic acid and the catalyst in a reactor, raising the temperature of the reactor, keeping reaction temperature to 140-220 DEG C, and carrying out reaction for 4-8h; and after the reaction is finished, carrying out vacuum dehydration on a reactant by utilizing a vacuum dehydration machine until an acid value reaches the standard, wherein the standard is as follows: the appearance of the reactant is pale yellow supernatant liquid, acid value / (mgKOH / g) is not larger than 2, hydroxyl value / (mgKOH / g) is 185-205, saponification value / ( mgKOH / g) is not larger than 25, and moisture is not larger than 1. With the adoption of the preparation process, the triolein can be conveniently obtained, and preparation cost is lowered.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a preparation process of glycerol trioleate. Background technique [0002] Triolein is used as an emulsifier, emulsion stabilizer, and wetting agent in food and cosmetics. In pharmaceutical production, with the continuous expansion of clavulanic acid production, the demand for triolein will increase Large, glycerol trioleate has been widely used in industry, as a medicinal raw material, its quality requirements are very high. It is insoluble in water, slightly soluble in ethanol, and soluble in chloroform, ether, and carbon tetrachloride. It is generally used as an emulsifier, and can be used in the textile printing and dyeing industry and the fermentation industry of medicine and food. It can also be used as a lubricant in the textile industry. ;Smoothing agent for post-processing of metals; used as emulsifier, emulsion stabilizer and wetting agent in food and cosmeti...
