Abstract: A process for the preparation of benzaldehydes of the general I where R1 is hydrogen or alkyl, wherein a compound of the formula II where X is hydrogen, hydroxyl or R2-COO-, and R2 is hydrogen or alkyl of 1 to 6 carbon atoms, is oxidized electrochemically in the presence of water, of an alkanoic acid of the formula R3COOH III where R3 is hydrogen or alkyl of 1 to 6 carbon atoms, and of a conductive salt.

Abstract: The alkanoic acid esters are prepared by anodic acyloxylation of aromatic or aromatic/heterocyclic compounds with an alkanoic acid in the presence of a supporting electrolyte of the formula Anodes are used which contain 40 to 95 per cent by weight of graphite and 60 to 5 per cent by weight of plastic. The substituents in the formula have the meanings specified in Claim 1. In the method of preparation, the electrolysis of alkanoic acid as a side reaction is avoided.

Abstract: Tetrahydrofuran derivs. of formula (I) are new: (R1 and R2 = 1-8C alkyl). The pref. cpd. has R1 = R2 = CH3. They are prepd. by conventional reduction of the corresp. 3-formyl cpds., pref. by catalytic hydrogenation using Ni catalysts. (I) are crosslinking agents for easy-care treatment of cellulose textiles. The finish obtd. is resistant to washing and equiv. to that using aminoplast precursors. They are also useful as intermediates for dyes, pharmaceuticals, auxiliaries and as polymer crosslinking agents.

Abstract: 1. A process for the preparation of 1-4-hydroxy-phenyl)-butan-3-one (I), wherein A. a corresponding 4-tert.-alkoxy-benzaldehyde of the general formula II see diagramm : EP0038480,P5,F2 where R is H or CH3 , is condensed with acetone under alkaline conditions to give the novel 1-(4-tert.-alkoxy-phenyl)-but-1-en-3-one of the general formula IIIa see diagramm : EP0038480,P5,F4 B. the latter is hydrogenated, during of after this condensation, to give the novel 1-(4-tert.-alkoxyphenyl)-butan-3-one of the formula IIIb see diagramm : EP0038480,P5,F6 and C. isobutene or 2-methyl-but-1(2)-ene is eliminated therefrom, at from 40 to 150 degrees C, in the presence of a catalytic amount of an acid.
