General description

Triisopropyl phosphate, an ester of secondary alcohol, is a non-phosphorylating organophosphorus compound. It is formed as a by-product during the synthesis of haloalkylphosphonates. Triisopropyl phosphate can be prepared from isopropyl alcohol by reacting with phosphorus oxychloride. It can also be obtained from triisopropyl phosphite.
