HCID 85301,4-Naphthoquinone

Procedure

A smaller portion of naphthalene is at the same time converted to 1,4maleic anhydride, or it is completely oxidized (to carbon dioxide and water). If the heat of reaction is too low, a greater amount of 1,4naphtaquinone is produced. If the temperature is too high, the proportion of maleic anhydride increases and the major part of naphthalene is completely oxidized. A part of orthoxylene is also converted to maleic anhydride or it undergoes complete oxidation. As a by-product of partial orthoxylene oxidation, phthalate is produced.
