Olein or oleic acid is a substance of natural origin, which is derived from vegetable and, more rarely, from animal fats. Technical olein is a mixture of fatty acids with an admixture of unsaponifiable substances and other organic compounds. It is obtained by compression or a non-pressing process.
Outwardly it is a transparent brownish viscous liquid, which is oxidized by access to oxygen.
GOST provides for the production of several grades of technical oleic acid - A, B and C, which differ in the total content of fatty acids, iodine number, pour point.
Acid Olein grade B-14 is produced according to GOST 7580-91.
In the same way they produce B-115 and analogues according to TU 9145-172-4731297-94.
Still some time ago let out technical olein of mark В on ТУ 9145-024-00336562-98 and on ТУ 9145-002-51043152-2005. But since they are of poor quality and, accordingly, cheap and not profitable brand B have been removed from production.
Still there are several analogues of foreign production qualifications are clean and higher, but the price is much higher than domestic brands.
