Method for synthesis of quaternary ammonium salts

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1974
Quaternary ammonium salts that contain the allyl moiety are easily hydrogenated on palladium catalysts to the corresponding quaternary salts, which contain the propyl moiety.

Synthesis of quaternary ammonium salts

1997
Since the early days of phase transfer catalysis (PTC), the most popular catalysts have been quaternary ammonium salts (quats). Among these, tetra- H-butylammonium bromide (TBAB), introduced by Brandstrom, triethyl- benzylammonium chloride (TEBA), initiated by Maskoza, and Stark’s tricaprylmethylammonium chloride (Aliquat 336 or Adogen 464) are more ...

Amines and salts of quaternary ammonium bases

1971
One of the most important groups of physiologically active compounds, having great significance for the vitality of living organisms, is the amines. The pesticidal properties of various amines and their salts with organic and inorganic acids have been studied.

Quaternary ammonium salts as colloidal electrolytes

Journal of Colloid Science, 1946
Abstract 1. 1. Freezing point depressions in solutions of dodecylbenzyldimethylammonium chloride and sulfamate have been measured. The osmotic coefficients of the chloride fall midway between the generalized curves of McBain and Brady for straight and branched chain compounds. The sulfamate is less associated in dilute solutions than the chloride.
