INTRODUCTION

Pyrophosphoryl Tetrachloride is a colorless fuming corrosive liquid .It consists of a pyrophosphate (a molecule with a P-O-P bond) group, where one phosphorus atom is bonded to four chlorine atoms and the other is bonded to three chlorine atoms. It is a reactive chemical compound and should be handled with care. Commonly used in the synthesis of other phosphorus-containing compounds and as a chlorinating agent in organic chemistry

Manufacture

It is manufactured by chlorination of Phosphorous Pentoxide with Phosphorous Trichloride followed by distillation process.
