N-(2-Hydroxyethyl)phthalimide synthesis

5synthesis methods
A synthetic method of N-(2-Hydroxyethyl)phthalimide. It was prepared by allowing 147.2g (1.0 mole) of phthalimide to react in an autoclave with 53.0g (1.20 moles) of ethylene oxide in the presence of 1.47g (1%) of active chromium III tri-2-ethylhexanoate (COT) and 400 ml of methylisobutyl ketone (MiBK) at 160° to 165°C for two hours. On cooling, the N-(2-Hydroxyethyl)phthalimide crystallized and was collected by filtration. A 94.7% yield of the hydroxyethyl imide was obtained.
