WebThe work procedure states to do an azeotropic esterfication with Chloroform or Carbon tetrachloride as entrainer. However the assistent told me to use DCM instead because … Web– Can be more easily dried than THF or DCM • Limited miscibility in water (14g/100g at 23°C) – Easy separation and recovery from water reduces the waste stream • Higher boiling point (80°C) compared to THF – Higher reaction temperature reduces overall reaction time • Low heat vaporization
