FAQ

What are the physical and chemical properties of Octadecanoic acid, hexadecyl ester (CAS: 1190-63-2)?

Octadecanoic acid, hexadecyl ester (CAS: 1190-63-2) is a waxy solid with a molecular weight of approximately 546.75 g/mol. It has a low solubility in water but is soluble in organic solvents like ethanol and acetone. Chemically, it is reactive towards bases, undergoing saponification, and can react with carboxylic acids to form esters. It is stable under normal conditions but may hydrolyze in the presence of strong acids or bases.

How is Octadecanoic acid, hexadecyl ester (CAS: 1190-63-2) typically synthesized?

Octadecanoic acid, hexadecyl ester is typically synthesized through the esterification of octadecanoic acid with hexadecanol in the presence of a strong acid catalyst like sulfuric acid or by using a mild acid catalyst such as phosphoric acid. The reaction proceeds with good selectivity and yields up to 90% of the ester product under optimal conditions.

What industries use Octadecanoic acid, hexadecyl ester (CAS: 1190-63-2)?

Octadecanoic acid, hexadecyl ester (CAS: 1190-63-2) is used in various industries including pharmaceuticals for drug formulations, polymers for enhancing plastic properties, and in the production of sensors and semiconductors for electronic applications.
