Abstract: A process for the separation of acids from reaction mixtures by means of an auxiliary base (I) is characterized by (a) the base (I) forming a salt with the acid that is liquid at temperatures that do not lead to significant decomposition of the product during separation of the liquid salt (b) the salt of the base (I) forming two non-miscible phases with the product or solution of the product in a suitable solvent.

Abstract: Disclosed is a method for separating acids from chemical reaction mixtures by means of an auxiliary base. Said auxiliary base b) forms a salt with the acid, which is liquid at temperatures at which the valuable product is not significantly decomposed during separation, and c) the salt of the auxiliary base and the valuable product or the solution of the valuable product form two immiscible fluid phases in a suitable solvent.

Abstract: Electrochemical preparation of (a) an orthocarboxylate ester (I), derived from an aliphatic carboxylic acid and, to provide alkoxy groups, a primary aliphatic alcohol (III); or (b) an orthocarbonate (Ia), derived from (III), by oxidation at a diamond electrode. To prepare (I), the electrolyte contains (III) and an aliphatic aldehyde (IV) (or its acetal in which alkoxy groups are derived from (III)), or a mixture of these compounds; and to prepare (Ia), it contains (III) and (I).
