What is the difference between oleic acid and oleic acid and vegetable oleic acid?

First of all, let's start with a detailed understanding of animal oleic acid:

Molecular weight: About 282

Appearance: pale yellow, transparent, oily liquid

Physicochemical properties:

Acid number (mg/g) 190-202 (mg/g) 195-205; saponification value; iodine value (Ig/100g) 80-100; (c) 4, the freezing point of water is 0.5% 8,12,16;

Use:

Mainly used in synthetic detergents, metal rust inhibitors, plastic plasticizers, ink, paint, carbon paper, ball pen oil and other raw materials. Is also the production of nylon 8 and 9 intermediates. It also has some application in textile auxiliaries, crude oil recovery and demulsifier.

Second, compare vegetable oleic acid:

Chemical name:

CIS -9- eighteen c acid

Physicochemical properties: room temperature light yellow transparent oily liquid, the melting point of 13.4 DEG C, the proportion of 0.8905, insoluble in water, soluble in ethanol, gasoline and other organic solvents, hydrogenation into stearic acid, chemical properties and chemical properties of unsaturated organic carboxylic acid.

Main use:

Widely used in plastic plasticizer, engineering plastics, synthetic fiber, nylon 8 and 9, synthetic detergent, soap, paint, ink, paper, carbon paper, pen oil and other raw materials, textile oil additives, wood preservative additives, oil recovery additives, demulsifier etc..

Producing synthetic pesticide emulsifier, textile printing and dyeing auxiliaries, various oleic acid soap and metal cutting fluid basic material. Can also be used as mineral flotation agent, such as stripping agent.
