Phthalimide is an organic compound with the molecular formula C₆H₄(CO)2NH. It is an imide derivative of phthalic anhydride. It is a sublimable white solid, slightly soluble in water, but more soluble in water with the addition of alkali. It is used as a precursor for other organic compounds, as a masked source of ammonia.

How is phthalimide prepared?

How is phthalimide formed?Phthalimide can be prepared by the following methods Heating alcohol ammonia with phthalic anhydride, yielding 95-97%. Alternatively, it can be prepared by treating the acid anhydride with ammonium carbonate or urea. It can also be caused by ammoxidation of ortho-xylene.

What functional groups are present in phthalimide?

Phthalimide has A nitrogen atom flanked by two carbonyl groups. This arrangement of carbonyl groups around the nitrogen atom causes the compounds involved to be slightly acidic.

What is an imine group?

In organic chemistry, imide is A functional group consisting of two acyl groups bonded to nitrogen. These compounds are structurally related to anhydrides, although imides are more resistant to hydrolysis.
