  • salts
  • The use of alkali metal, alkaline earth metal, ammonium and substituted ammonium salts of alkyl and alkanol sulfonic acids as additives in pure metal and metal alloy sulfonic acid electroplating baths has a number of unexpected benefits including wider useful current density range, improved appearance and in the case of tin improved oxidative stability.

  • An additional significant appearance is to reduce the overall costs of this type of bath with the more economical salts of alkyl and alkanol sulfonic acids. (patentgenius.com)
  • 1. A method of improving the plating performance of sulfonic acid based electroplating baths, comprising the step of replacing at least a portion of the alkyl sulfonic acidelectrolyte with a salt of an alkanol sulfonic acid or of a mixture of an alkyl sulfonic acid and an alkanol sulfonic acid, wherein the replacement salt is selected from the group consisting of alkali metal, alkaline earth metal, and ammonium orsubstituted ammonium salts.

  • Alkali metal salts of phytic acid, e.g., sodium phytate, are also suitable as organic builders. (google.es)
  • A further object is to provide a new class of highly effective polyelectrolyte'builder compounds comprising Watersoluble salts of polymeric aliphatic polycarboxylic acids, as described hereinafter. (google.es)
  • The pharmaceutically acceptable salts are the acid addition salts of the formula I free base. (patentgenius.com)
  • The hydrohalide salts, especially the hydrochlorides and maleic acids, especially the hydrogen maleate, are preferred. (patentgenius.com)
  • amino acid
  • Corticotropin releasing factor (herein referred to as CRF), a 41 amino acid peptide, is the primary physiological regulator of proopiomelanocortin (POMC) -derived peptide secretion from the anterior pituitary gland [J. Rivier et al. (allindianpatents.com)
  • sodium
  • 9. A method of increasing the useful upper current density range of a tin/lead methane/methanol sulfonate plating bath and thereby allowing plating at higher speeds, said method comprising the step of replacing at least a portion of the methanesulfonic acid with sodium isethionate.

  • solution
  • Builder compounds have been found to have some effect, for instance, in such areas as stabilization of solid soil suspension, emulsification of soil particles, the surface activity of aqueous detergent solutions, solubilization of water-insoluble materials, foaming or sud producing characteristics of the washing solution, peptization of soil agglomerates, neutralization of acid soil, and the inactivation of mineral constituents present in the washing solution.
