    摘要: In a process for hydrodimerizing an olefinic nitrile, amide or ester by electrolyzing an aqueous solution of the olefinic compound, quaternary ammonium or phosphonium ions and an alkali metal phosphate, borate or carbonate in a single-compartment cell, anode corrosion is substantially lessened by use of a cell having an anode consisting essentially of carbon steel. Even at relatively high temperatures and current densities, corrosion of such an anode is surprisingly slow. Even lower rates of corrosion of such an anode are achieved when the electrolyzed solution contains an alkali metal phosphate and an alkali metal borate.

    摘要: Diamides and triamides of aliphatic polycarboxylic acids which may be substituted in the alkylene group by alkyl or alkenyl groups, provide growth regulants for plants and trees. Preferred are N-substituted succindiamides.
