| titleOfInvention | A process for manufacturing a naphthalic acid derivative |
| abstract | 1,224,418. Naphthalic acid derivatives. MITSUBUSHI CHEMICAL INDUSTRIES Ltd. 19 June, 1969 [19 June, 1968; 7 Oct., 1968], No. 31159/69. Heading C2C. Compounds of formula wherein each of X and Y is a halogen atom or a nitro group, and m + n is 0 or 1, and anhydrides thereof, are prepared by oxidation with chromic acid in sulphuric acid of a compound of formula followed if desired by heating to form the anhydride. The chromic acid may be prepared in situ by reaction of sulphuric acid with a sodium, potassium or ammonium bichromate or chromate or chromic anhydride. The oxidized product is preferably subjected to further treatment with an alkaline-activatable oxidizing agent, for example sodium or potassium hypochlorite, in aqueous alkaline solution. |
