Abstract: A composite nickel-containing electroplate is formed on a base metal surface by electroplating on the surface an adherent nickel or nickel alloy layer having a thickness of from about 0.15 to 1.5 mils and an average sulfur content of less than about 0.03%. An intermediate nickel or nickel alloy layer, having a thickness of from about 0.005 to 0.2 mils and an average sulfur content of from about 0.05 to 0.3% is then electroplated on the lower layer. An adherent upper nickel or nickel alloy having a thickness of from about 0.2 to 1.5 mils and average sulfur content of from about 0.02 to 0.15% is then electroplated on the intermediate layer, the upper layer containing a lower percentage of sulfur then the lower layer. The source of sulfur, for at least the intermediate layer, is provided by including novel thioethersulfonates of nitriles or amides in the plating bath for that layer.

Abstract: The present invention is directed broadly to the manufacture of aromatic aldehydes and acids, and is more specifically concerned with the preparation of anisaldehyde utilizing a manganic salt to oxidize either methoxytoluene or the benzyl or toluol sulfonic ester of p-cresol whereby under carefully controlled conditions there is obtained a minimum of tars, a minimum of aromatic acids and a minimum utilization of the methoxytoluene for conversion to anisaldehyde.

Abstract: The instant invention is broadly directed to acid zinc electroplating baths and the use thereof wherein there is utilized water soluble polyglycidols and their derivatives which have been found useful in relatively small additive amounts to the plating solutions and accomplish marked improvements in the brightness of the cathode deposits and also increase the throwing power of the plating solutions.
