Surface Active N-Acylglutamate. VI.

Surfactants - Surface Active Agents

The definition for a detergent is a cleaning agent. The main cleaning agent used in earlier days was soap. This term means a compound formed from the reaction of a fatty acid with a base such as caustic soda, forming the sodium soap of the acid. The more commonly used cleaning agent in this day and age is the synthetic detergent (SYNDET) which is a formulation such as TIDE or FAB. The essential...

Chemical modification of viral RNA. VI. The action of N-methyl-N'-nitro-N-nitrosoguanidine.

N-Methyl-N'-nitro-N-nitrosoguanidine (MNNG, "nitrosoguanidine") has been extensively used as an effective mutagen for DNA-containing organisms and virusesl-4 but appears not to have been used with RNA viruses. Nothing definitive seems to have been reported about its mode of action. This paper deals with the effects of MNNG on the infectivity, mutation frequency, and base composition of tobacco ...

Diammonium bis­[(2-amino­acetato-κ2 N,O)(2,2′-bipyridine-κ2 N,N′)(N,N-dimethyl­formamide-κO)copper(II)] hexa­cosa­oxidoocta­molybdate(VI)

The title compound, (NH(4))(2)[Cu(C(2)H(4)NO(2))(C(10)H(8)N(2))(C(3)H(7)NO)](2)[Mo(8)O(26)], contains a centrosymmetric β-type octa-molybdate anion, two copper(II) complex cations and two ammonium ions. The Cu(II) atom is coordinated in a square-pyramidal geometry by a 2,2'-bipyridine and a 2-amino-acetate ligands in the basal plane and by an O atom of N,N-dimethyl-formamide in the apical posit...

Effect of Additional Hydroxyl Group On Dissolution Of Azo Dyes derived from N-carboxylic acid-1,8-naphthalimide in aqueous solutions containing various surface active agents

Dissolution of azo dyes derived from N-carboxylic acid-1,8-naphthalimide was studied in aqueous solutions containing formaldehyde condensation of naphthalenesulphonic acid and fatty alcohol ethylene oxide compound surfactants and effect of additional hydroxyl group on chemical structure of dye on dissolution was investigated. In addition, the effect of important factors on dissolution of used d...
