Abstract: A cpd of formula (I) where R' to R6 are alkyl, is dehydrogenated in presence of a Co- or Mn-complex of an azomethine, with the aid of atmospheric oxygen, in an inert org. solvent, to give a lactone cpd. (II) which is then isolated in known manner. Prods. are obtd. in high yield and purity.

Abstract: Benzoylbenzoic acid prepn. Oxidation of indanes of formula:- (R1, R2, R3 are each alkyl; R1 and/or R3 can be H), oxidised with HNO3 and/or Cr-VI compounds gives, simply and economically, better yields of high-purity o-benzoylbenzoic acid (valuable for syntheses, especially for anthraquinone) without formation of considerable quantities of o-acetylbenzophenone. Temperature for HNO3 oxidation is 50 - 250 degrees C. Less than 1.5 x stoichiometric requirement of Cr-VI compounds is preferred. In a preferred method, at least 10% stoichiometric requirement of alkaline bichromate is added simultaneously to the HNO3.

Abstract: Auramine salts are prepd by (a) forming the auramine base; (b) dissolving it in org. water-immiscible solvent (II); and (c) extracting the base by reaction with aq. acid (III) contg. glycol of formamide, to form the salt where the solvent is immiscible with glycol and formamide when acid is present. The base is liberated in soda wash. The NH4 salt is sulphate, chloride, sulphamate, sulphanylate or toluene sulphonate. (II) is tri- or tetra-chlorethylene. (III) is sulphuric, hydrochloric or low mol. wt carboxylic acids. The method gives, better yields, reduced effluent and needs smaller plant.

Abstract: The reaction components are reacted, opt. with the addition of an ammonium salt and the reaction prod. which may contain liberated ethylauramine base, is collected in an organic, water-immiscible solvent. The ethylauramine base is then extracted with an acid contg. HCHO or glycol with formation of the salt, >80% yields of a highly pure prod. are obtd.

Abstract: Salts have formula: (Et2N-pC6H4)2-C=NH2 circled positive A circled negative (where A circled negative is NO2 circled negative or NO3 circled negative) and are prepd. by double decompsn. reaction of a water-sol. ethyl auramine salt with a water sol. nitrate or nitrite.

Abstract: Cpds of formula are claimed where X- is a Br- or I- anion. Prepn. is by reaction of a water-sol. ethylauramine-salt with a water-sol. bromide or iodide; or an ethylauramine base is reacted with diluted aq. HBr or HI.
