Chemical Properties
Castor oil fatty acid, also known as ricinoleic acid, is a long-chain unsaturated hydroxy acid. It is yellow viscous oily liquid. It is soluble in ethanol, acetone, ether and chloroform, but insoluble in water.
Characteristics
The presence of both hydroxy and carboxy groups in the molecule of ricinoleic acid enables it to undergo intermolecular esterification, thus resulting in the formation of the oligomeric ricinoleic acid. The oligomeric ricinoleic acid with different acid value (which is an indirect index for oligomerization degree) has different applications. For example, as an additive in shampoos, the oligomeric ricinoleic acid with an acid value of 60–90 mg KOH/g is required while for cosmetic formulations, an acid value of 20–40 mg KOH/g is suitable. The oligomeric ricinoleic acid can also be used as lubricant for metal cutting oils due to its appropriate viscosity, good adsorptivity and film formation ability on metal surfaces.
Preparation
Ricinoleic acid can be easily prepared by hydrolysis of castor oil.
Check Digit Verification of cas no
The CAS Registry Mumber 61789-44-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,7,8 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 61789-44:
(7*6)+(6*1)+(5*7)+(4*8)+(3*9)+(2*4)+(1*4)=154
154 % 10 = 4
So 61789-44-4 is a valid CAS Registry Number.
