WILFARIN OA-7075 is a kind of unsaturated fatty acid with its molecular structure containing a carbon-carbon double bond, being the fatty acid that makes olein.
WILFARIN OA-7075 is one of the most extensive natural unsaturated fatty acids.
Oil lipid hydrolysis can lead to WILFARIN OA-7075 with the chemical formula being CH3 (CH2) 7CH = CH (CH2) 7 • COOH.
The glyceride of the WILFARIN OA-7075 is one of the main ingredients of olive oil, palm oil, lard and other animal and vegetable oils.
WILFARIN OA-7075's industrial products often contain 7~12% saturated fatty acids (palmitic acid, stearic acid) and a small amount of other unsaturated fatty acids (linoleic acid).
WILFARIN OA-7075 is colorless oily liquid with the specific gravity being 0.895 (25/25 ℃), freezing point of 4 ℃, the boiling point of 286 °C (13,332 Pa), and the refractive index of 1.463 (18 ° C).
WILFARIN OA-7075's iodine value is 89.9 and its acidic value is 198.6.
WILFARIN OA-7075 is insoluble in water, but soluble in alcohol, benzene, chloroform, ether and other volatile oil or fixed oil.
Upon exposure to air, especially when containing some impurities, WILFARIN OA-7075 is susceptible to oxidation with its color turning into yellow or brown, accompanied with rancid odor.
At normal pressure, WILFARIN OA-7075 will be subject to decomposition 80~100 °C.
WILFARIN OA-7075 is manufactured through the saponification and acidification of animal and vegetable oils.
WILFARIN OA-7075 is an indispensable nutrient in animal food.
WILFARIN OA-7075's lead salt, manganese salt, cobalt salt belong to paint driers; its copper salt can be used as fish net preservatives; its aluminum salt can be used as the water repellent agent of fabric as well as the thickener of some lubricants.
When being epoxidized, WILFARIN OA-7075 can produce epoxy oleate (plasticizer).
Upon subjecting to oxidative cracking, WILFARIN OA-7075 can generate azelaic acid (raw material of polyamide resin).
WILFARIN OA-7075 can be sealed.
Store WILFARIN OA-7075 on darkness.
WILFARIN OA-7075 exists in the animal and vegetable oil fat in large amount, being mainly in the form of glyceride.
Some simple oleic esters can be applied to the textile, leather, cosmetics and pharmaceutical industries.
The alkali metal salt of WILFARIN OA-7075 can be dissolved in water, being one of the main components of soap.
The lead, copper, calcium, mercury, zinc and other salts of oleic acid are soluble in water.
WILFARIN OA-7075 can be used as dry lubricants, paint drying agent and waterproofing agent.
WILFARIN OA-7075 mainly comes from nature.
Oil fat containing high content of WILFARIN OA-7075, after subjecting to saponification and acidification separation, can produce oleic acid.
WILFARIN OA-7075 has cis-isomers.
Natural WILFARIN OA-7075 is all cis-structure (trans-structure oleic acid can’t be absorbed by the human body) with certain effect of softening the blood vessels.
WILFARIN OA-7075 also plays an important role in the metabolism process of human and animal.
However, the WILFARIN OA-7075 synthesized by the human body itself can’t meet the needs, so we need food intake.
Thus, consumption of edible oil of high WILFARIN OA-7075 content is healthy.

Preparation
(1) Extract WILFARIN OA-7075 directly from the vegetable oil, namely, apply saponification for extraction, upon stirring, send the oil into the steam to make the temperature rise to 80~100 °C, then add alkaline solution to hydrolyze the oil fat.
After hydrolysis, we can obtain mixed fatty acids.
Further apply distillation and cooling so that they are separated.
This method demands large labor intensity, energy consumption, alkali consumption and is generally not used.
(2) Take vegetable oil or animal oil as raw material; apply atmospheric catalytic hydrolysis for preparation of oleic acid.
For the catalyst, we can also choose alkyl benzene sulfonic acid.
Alternatively, we can apply intermittent pressure catalytic cracking method using zinc oxide as the catalyst at a pressure of 10.13 × 105~35.46 × 105 Pa and temperature of 150~230 °C.
We can also apply continuous, backwash and high pressure lysis under the pressure of 5~5.2MPa and temperature of 260 ℃.
For the catalyst, we can also use zinc oxide.
This method can produce higher efficiency according to the previous two kinds, but being not suitable for oil fat of higher unsaturated degree and high content of hydroxy.
Using the above three methods, we can prepare mixed fatty acids, and then conduct separation and refinement.
First apply distillation for crude fraction, and the distillation was carried out under reduced pressure (0.133 103 to 1.07 103 Pa).
Maintain the distillation temperature not exceed 260 °C.
The distilled fatty acid is further subject to rectification using the difference between the boiling points of the fatty acids.
We can also conduct refinement using crystallization method based on the melting points of various kinds of fatty acids.
We can also apply solvent extraction for refining.
(3) In 1925, people had already used ethyl acetoacetate as raw material for the synthesis of oleic acid.
With the development of petrochemical industry, synthetic oleic acid process has also been developed.
We can prepare WILFARIN OA-7075 from petroleum olefin.
