Naphthalic peroxide

Phthaloyl peroxide, in contrast to diphenoyl peroxide cannot decarboxylate readily to give a stable lactone. The corresponding lactone (25) is unreasonably strained. The as yet unknown phenanthrene dicarboxylic acid and naphthalic peroxides (26) and (27) could form stable lactone radical anions by loss of CO2 on acceptance of an electron from the activator.

The oxidation of naphthalic acid (1,8-naphthalenedicarboxylic acid) by peroxide, rather surprisingly, does not proceed by formation of a cyclic peroxide but rather via a dioxirane [53] (a three-membered ring containing a carbon atom and a peroxide group). CL is observed from this reaction. [Pg.115]

Naphthalic acid imide 69 is obtained through air oxidation of acenaphthene 72 with vanadium peroxide as a catalyst. The intermediate, naphthalic anhydride 73, is subsequently reacted with ammonia ... [Pg.474]

This deficiency is overcome by application of a hard coat to the amorphous resins this substantially improves resistance to the solvents and chemicals such as NMP, IPA, acetone, methanol, THF, ethyl acetate, 98% sulfuric acid, glacial acetic acid, 30% hydrogen peroxide, and saturated bases such as sodium hydroxide [13]. With poly(ethylene terephthalate) and of poly(ethylene naphthalate) films a hard coat is not required for solvent resistance. [Pg.167]
