Abstract:
A method of producing lead dioxide/titanium composite electrodes by anodic deposition of lead dioxide on a titanium surface, in which an intermediate layer of a carbide or boride of an element of sub-group 4 or 5 and/or silicide of an element of sub-group 4, 5 or 6 of the periodic table of the elements and/or silicon carbide, is applied to the titanium surface before depositing the lead dioxide.
Abstract:
A novel cyclohexane hexacarboxylic acid and its production by dehydration of a known cyclohexane hexacarboxylic acid with the formation of two novel dianhydrides and hydrolysis of the dianhydrides.
Abstract:
Pinacols are prepared by electrolytic hydrodimerization of carbonyl compounds in non-compartmented cells using a mixture of from 5 to 75% by weight of the carbonyl compound, from 5 to 90% by weight of the alcohol corresponding to the carbonyl compound, from 0.1 to 3% by weight of a quaternary ammonium salt and from 0 to 30% by weight of water.
Abstract:
MANUFACTURE OF HEXADIENE-DIOLIC ACIDS BY THE ELECTROCHEMICAL REDUCTION OF BENZENE-DIOIC ACIDS IN AN ELECTROLYTIC CELL CONTAINING DIAPHRAGMS, USING A CATHOLYTE CONTAINING THE DIOIC ACID, WATER AND A WATER-SOLUBLE ORGANIC SOLVENT, WHEREIN THE FLOW OF ELECTROLYSIS CURRENT IS PERIODICALLY INTERRUPTED AND THE CELL SHORT-CIRCUITED.
Abstract:
The production of diesters of dicarboxylic acids having six to 18 carbon atoms and alcohols of four to 12 carbon atoms by electrochemical condensation of monoesters of dicarboxylic acids of four to 10 carbon atoms and alcohols of four to 12 carbon atoms in solution in methanol which contains from 0.01 to 5% by weight of water.
Abstract:
PROCESS FOR PRODUCING LACTIC ACID BY THE HYDROLYSIS OF LACTIC ACID NITRATE IN WHICH THE LACTICE ACID NITRATE IS REACTED WITH MORE THAN TWICE ITS WEIGHT OF WATER. IT HAS BEEN FOUND THAT HIGH YEILDS OF LACTICE ACID CAN BE OBTAINED EITHER FROM PURE LATICE ACID NITRATE OR FROM THE REACTION PRODUCT CONTAINING IMPURITIES AS WELL AS LACTIC ACID NITRATE.
