Embodiment 1

[0013] Take by weighing 200g of safflower seed oil (containing 80% of linoleic acid), put it in a 500ml three-necked flask, add 3g of the pulverized hydrogenation catalyst of the corresponding amount, that is, the weight content is 1.5%, fill it with nitrogen as a protective atmosphere, and start Stir and heat with a constant temperature magnetic stirrer, raise the temperature to 250° C., react for 2.5 hours, and cool to room temperature under the protection of nitrogen. Then filter and remove the catalyst to obtain a conjugated linoleic acid product with a conjugated linoleic acid content of 38% and a conjugated conversion rate of 48.3%.

Embodiment 2

[0015] Take by weighing 200g of safflower seed oil (containing 80% of linoleic acid), put it in a 500ml three-necked flask, add 3g of the pulverized hydrogenation catalyst of the corresponding amount, that is, the weight content is 1.5%, fill it with nitrogen as a protective atmosphere, and start Stir and heat with a constant temperature magnetic stirrer, raise the temperature to 300° C., react for 3 hours, and cool to room temperature under the protection of nitrogen. Then filter to remove the catalyst to obtain the conjugated linoleic acid product, which has a conjugated linoleic acid content of 41.9% and a conjugated conversion rate of 52.2%.

Abstract

A conjugated linoleic acid is prepared from safflower seed oil through adding ground metal Ni as hydrocatalyst, filling nitrogen gas, stirring, heating to 250-300 deg.C, reaction for 2.5-3 hr, cooling and filter. Its advantages are simple preparing process and low cost.

Description

technical field [0001] The invention relates to a method for manufacturing conjugated linoleic acid, which belongs to the field of chemical product manufacturing. Background technique [0002] The essence of conjugated linoleic acid is the general term for various positions and spatial isomers of essential fatty acids—conjugated dienes derived from linoleic acid. In general, conjugated linoleic acid can be considered as a derivative of c9, c12-18:2 (LA). Scientists have found that conjugated linoleic acid has many important physiological functions: anti-cancer effect, anti-atherosclerosis, participates in fat decomposition and metabolism, enhances the body's immunity, promotes bone tissue metabolism, etc. The natural content of conjugated linoleic acid is very low, and artificial synthesis must be its largest source. [0003] The traditional synthesis method of conjugated linoleic acid is to use a large amount of high-boiling point solvents such as ethylene glycol, glycero...
