| abstract | Amides of dithiocarbonic acid, prepared from carbon bisulphide and an aliphatic secondary amine containing an alkyl chain of at least three carbon atoms are stated to be dispersing agents for solvents and other substances which are insoluble in strong alkali lyes. In examples, amides of dithiocarbonic acid derived from the following secondary amines are employed : di-n-propyl and n-butyl amines, ethyl-n-butylamine, di-n-butylethylenediamine, n-butylmonoethanolamine.ALSO:Amides of dithiocarbonic acid, prepared from carbon bisulphide and an aliphatic secondary amine containing an alkyl chain of at least three carbon atoms are used as wetting agents in mercerising vegetable fibres with alkaline lyes. Dispersing agents, such as phenols, sulphurized phenols and sulphonated oils may be added as well as solvents and other insoluble substances. In examples, the amides of dithiocarbonic acid are prepared from the following secondary amines, usually in the presence of caustic alkali, and are added to customary alkaline mercerising lyes: di-n-propylamine, ethyl-n - butylamine, di - n - butylethylene-diamine, di-n-butylamine, n-butylmonoethanol-amine. Di - n - butylethylenediamine and ethyl - n - butylamine are obtained by reduction of the azomethines derived from butyraldehyde and ethylenediamine and ethylamine respectively. |
