  • Phenyl
  • A copoly(arylene ether) (PAE) with high fluorine content and a copoly(arylene ether nitrile) (PAEN) with high nitrile content, each containing pendant phenyl sulfonic acids were synthesized. (unt.edu)
  • sulfonic acid groups were introduced by mild post-sulfonation exclusively on the para-position of the pendant phenyl ring in PHQ. (unt.edu)
  • dyes
  • the free acids are widely used as catalysts in organic syntheses, while the salts and other derivatives form the basis of the manufacture of detergents, water-soluble dyes and catalysts , sulfonamide pharmaceuticals, and ion-exchange resins . (britannica.com)
  • Such operations are conducted on a manufacturing scale in the preparation of the sodium salts of TPPTS (used in catalysts as described above), in the preparation of alkylated benzenesulfonic acids (used as synthetic detergents), and in the preparation of anthraquinonesulfonic acid (used in the manufacture of alizarin and other dyes).

  • salts
  • The free sulfonic acids and their salts with metals and nitrogenous bases do not show contact insecticidal and acaricidal properties, but some sulfonic acids of the triphenylmethane series and substituted arylureas are active mothproofing agents. (springer.com)
  • The salts of sulfanilic acid and related compounds have a fungicidal effect against rust of grains, but the mechanism of this action is still not entirely clear. (springer.com)
  • 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)
  • present
  • The present invention relates to the use of at least one alkane sulphonic acid, with formula R--SO.sub.3H, where R represents a saturated, linear or branched hydrocarbon chain, comprising 1 to 4 atoms of carbon for removing rust from all types of surface, in particular from metal surfaces, specifically iron, steel and others.

  • strong
  • The alkyl- and arylsulfonic acids have herbicidal properties, but they are not strong enough to be of practical importance. (springer.com)
  • This is expected to help the readers and players in gaining a strong understanding of the Dinonyl Naphthalene Sulfonic Acid market across the globe. (mynewsdesk.com)
