DIPHENYL PHOSPHITE Usage And Synthesis

Chemical Properties

clear liquid

Uses

Diphenyl Phosphite is a reactant used in the synthesis of α-hydroxyphosphonates and α-hydroxyphosphinates for their antioxidant and antimicrobial activity.

Purification Methods

Diphenyl Phosphite can be purified by distillation. Best done in small batches since decomposition frequently occurs. Phenol can be substantially removed by heating at 150 °C at water pump vacuum.
