Phthalimide is the organic compound with the formula C 6 H 4 (CO) 2 NH. It is the imide derivative of phthalic anhydride. It is a sublimable white solid that is slightly soluble in water but more so upon addition of base. It is used as a precursor to other organic compounds as a masked source of ammonia. [2]
In organic chemistry, phthalic acid is an aromatic dicarboxylic acid, with formula C 6 H 4 (CO 2 H) 2 and structure HO(O)C−C 6 H 4 −C(O)OH. Although phthalic acid is of modest commercial importance, the closely related derivative phthalic anhydride is a commodity chemical produced on a large scale. [ 4 ]
Phthalates are produced industrially by the acid catalysed reaction of phthalic anhydride with excess alcohol.The synthesis of diethyl phthalate is illustrative of this: . The properties of the phthalate can be varied by changing the alcohol, [12] allowing for an almost limitless range of products, although only around 30 are, or have been, commercially important.

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Dimethyl phthalate (DMP) is an organic compound and phthalate ester. it is a colourless and oily liquid that is soluble in organic solvents, [4] but which is only poorly soluble in water (~4 g/L).
