General description

Triisopropyl orthoformate (TIPO) is formed during the reaction of dichlorofluoromethane with potassium isopropoxide in isopropyl alcohol. Separation of TIPO from n-hexane by dense carbon nanotube (CNT) membranes by pervaporation has been reported.

Application

Triisopropyl orthoformate may be used for the preparation of 2-(diisopropoxymethyl)oxirane.
