Abstract: Add to 2657234; 2555736. Prepn. of halonitrobenzenes of formula (I) is effected by (a) reacting an anilide of formula (II) with HNO3; (b) reacting the resulting nitroanilide (III), without isolating it from the reaction mixt., with an acid and H2O at >=25 degrees c; (c) reacting the resulting nitroaniline (IV), without isolating it from the reaction mixt., with a halogenating agent in the presence of H2O and acid; and (d) reacting the resulting halonitroaniline (V), without isolating it from the reaction mixt., with an aliphatic, alicyclic or araliphatic alcohol and nitrosating agent in the presence of acid and H2O at >=35 degrees C. R1 and R2 are halogen, or R2 can be H; R3 is H or an aliphatic gp.

Abstract: Prepn. of indazoles of formula: where R1 gps. are the same or diff. and are H, aliphatic, cycloaliphatic, araliphatic or aromatic gp., or halogen; R2 is H or aliphatic gp is by reaction of a cpd. of formula: in presence of acetic acid, an alkali metal alkanoate and an inert solvent with an alkyl nitrile, an ester of glycol or a deriv. with nitrous acid and/or nitrous gases and removing in known manner the acetyl gp. from the 1-acetylindazole. The simple, economica process is applicable to industrial scale and gives high yields of good quality prodt., used as inters. for dyes. drugs and pesticides.

Abstract: 1,246,018. Malonodialdehyde dioxime. BADISCHE ANILIN- & SODA-FABRIK A.G. 22 Jan., 1969 [23 Jan., 1968], No. 3522/69. Heading C2C. Malonodialdehyde dioxime is prepared by reacting hydroxylamine, or a salt thereof, with a #-aminoacrolein, of formula in which each R is an aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon radical, or -NRR represents a heterocyclic ring. The process is preferably effected in an inert solvent, at a temperature of - 10 C. to + 105 C. and a pH of 2 to 8, using 2 to 6 moles of hydroxylamine, or salt thereof, per mole of #-aminoacrolein.

Abstract: Process comprises a catalytic oxidation of indanes of formula (I), using oxygen in the gaseous phase (R1, R2, R3 same or different, are each alkyl, or R1 and/or R3 may be H). Specif. 1-methyl-3-phenyl-indane is catalytically oxidised by air at 160-500 degrees C, pref. using a supported iron-vanadium catalyst. Anthraquinone is a starting material for dyestuffs and pesticides.
