摘要： A process is disclosed for preparing phthalides by cathodic reduction of phthalic acid or phthalic acid derivatives, in which the carboxylic acid units may be substituted by units which can be derived by a condensation reaction from carboxylic acid units and in which one or several hydrogen atoms of the o-phenylene unit of the phthalic acid m ay be substituted by inert radicals. This process is characterised in that the reduction is carried out in an organic solvent which contains le ss than 50 wt % water and in a non-divided electrolytic cell.

摘要： Phthalides in as-obtained phthalide synthesis reaction mixtures are recovered in pure form by(a) distilling compounds having a boiling point below the boiling point of the phthalide from the reaction mixture, provided such compounds are present in the reaction mixture, to obtain a crude phthalide as bottom product,(b) crystallizing the phthalide from a melt of the crude phthalide.

摘要： Pure phthalides are produced from the reaction mixtures obtained in the phthalide production process by a) distilling off compounds with a boiling point below the boiling point of the phthalide from the reaction mixture, if such compounds are present, to obtain a residue of crude phthalide, and b) crystallising phthalide from a melt of the crude phthalide.

摘要： This invention is for the preparation of benzaldehyde dialkyl acetals of the general formula I in which R is C1-C6-alkyl and R is C1-C6-alkyl, C1-C6 -alkoxy, halogen, cyano or carboxyalkyl having from 1 to 6 carbon atoms in the alkyl group, and n is an integer from 1 to 3 and the radicals R , in the case of n > 1, can be identical or different, by electrochemical oxidation of substituted toluene compounds of the general formula II by oxidizing a substituted toluene compound II in the presence of an alkanol R -OH and an auxiliary electrolyte (supporting electrolyte) in an electrolytic cell, depressurising the reaction solution thus obtained, outside the electrolytic cell, to a pressure which is lower than the pressure in the electrolytic cell by from 10 mbar to 10 bar, and A) in the case of discontinuous operation, separating the gas liberated during expansion from the reaction solution, recycling the reaction solution into the electrolytic cell at least once, electrolysing, depressurising and separating from the liberated gas, and finally working up to give the product, or B) in the case of continuous operation, working up part of the reaction solution to give the product, admixing the remaining part of the reaction solution with such an amount of the originally employed reaction solution as corresponds to the part drawn off, recycling into the electrolytic cell, electrolysing and depressurising.

摘要： Process for manufacturing hydroxycarboxylic acid esters of the general formula: in which n is an integer from 0 to 10, R and R are hydrogen atoms, hydroxyl or alkoxy groups, aliphatic or olefinic, straight-chain, branched or ring-type hydrocarbon radicals, where R and R may also stand jointly for an alkylene radical and the hydrocarbon radicals may also be substituted by halogen atoms, or hydroxyl, epoxy or nitrile groups, and R is a low-molecular-weight alkyl radical, by electrochemical oxidation of hydroxyaldehydes of the general formula: in the presence of alcohols of the formula R OH and of ionogenic bromides or chlorides in an unpartitioned electrolysis cell.
