Specification
Oleic acid, its cas register number is 112-80-1. It also can be called Oelsauere; Oleine 7503; Oleinic acid; Omega-9 Fatty Acids; Pamolyn; Tego-oleic 130; UNII-2UMI9U37CP; Vopcolene 27; cis-Octadec-9-enoic acid; cis-delta(sup 9)-Octadecenoic acid; delta9-cis-Oleic acid; l'Acide oleique. Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colourless oil, although commercial samples may be yellowish. And it is found in various animal and vegetable sources which the most abundant fatty acid in human adipose tissue.
Physical properties about Oleic acid are: (1)ACD/LogP: 7.698; (2)# of Rule of 5 Violations: 1; (3)ACD/LogD (pH 5.5): 6.90; (4)ACD/LogD (pH 7.4): 5.11; (5)ACD/BCF (pH 5.5): 66473.35; (6)ACD/BCF (pH 7.4): 1065.97; (7)ACD/KOC (pH 5.5): 58464.46; (8)ACD/KOC (pH 7.4): 937.54; (9)#H bond acceptors: 2; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 15; (12)Index of Refraction: 1.467 ; (13)Molar Refractivity: 87.063 cm3; (14)Molar Volume: 313.897 cm3; (15)Polarizability: 34.514 10-24cm3; (16)Surface Tension: 33.875 dyne/cm; (17)Density: 0.9 g/cm3; (18)Flash Point: 270.099 °C; (19)Enthalpy of Vaporization: 66.53 kJ/mol; (20)Boiling Point: 359.999 °C at 760 mmHg
Preparation of Oleic acid: Extraction of triolein from olive oil – 3 liters of extra virgin olive oil are poured into a 5 liter one necked boiling flask and the flask is set up for fractional vacuum distillation. The air is evacuated until the pressure is only 8 torr and the boiling flask heated gradually to 240C. Collect what comes over from 230-240C. What has been collected is reasonably pure (>97%) triolein.
Use of Oleic acid: Oleic acid is included in normal human diet as part of animal fats and vegetable oil. Oleic acid as its sodium salt is a major component of soap as an emulsifying agent. It is also used as emollient. Small amounts of oleic acid are used as an excipient in pharmaceuticals, oleic acid is used as an emulsifying or solubilizing agent in aerosol products. Oleic acid is also used to induce lung damage in certain types of animals, for the purpose of testing new drugs and other means to treat lung diseases. Specifically in sheep, intravenous administration of oleic acid causes acute lung injury with corresponding pulmonary edema. This sort of research has been of particular benefit to premature newborns, for whom treatment for underdeveloped lungs (and associated complications) often is a matter of life and death.
When you are using this chemical, please be cautious about it as the following:
1. Wear suitable protective clothing and gloves;
2. Wear suitable gloves and eye/face protection;
3. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice;
4. Wear suitable protective clothing;
