Hydroxystearic acid - Introduction
12-Hydroxystearic acid is a fatty acid with the chemical formula C18H36O3 and a molecular weight of 300.47664. It is a hydroxy stearic acid that is mainly found in natural plant oils such as palm oil and sunflower oil.
Properties:
12-Hydroxystearic acid is a white solid that is insoluble in water but soluble in organic solvents such as ethanol, ether, and chloroform. It exhibits properties similar to stearic acid, but the presence of the hydroxyl group allows it to be used as a catalyst in specific chemical reactions.
Uses:
12-Hydroxystearic acid is primarily used in the synthesis of lubricants and lubricating greases to enhance their high-temperature performance and stability. Additionally, it finds applications in cosmetics, pharmaceuticals, and food additives.
Synthesis:
12-Hydroxystearic acid can be synthesized by hydroxylating stearic acid or hydrogenating wax through a catalytic reaction.
Safety:
12-Hydroxystearic acid is generally considered safe, but it is important to follow proper safety precautions when handling it to avoid inhalation, skin contact, or eye contact. In case of accidental exposure, rinse with plenty of water and seek medical assistance.
