Abstract
The invention comprises new alkane-a ,o -bis-trimethylammonium methosulphates of general formula: <FORM:0685085/IV (b)/1> where n is an integer from 4 to 10 inclusive. They may be prepared by treating dimethyl sulphate with an a ,o -bis-(dimethylamino) derivative of a saturated straight chain aliphatic hydrocarbon containing from 4 to 10 carbon atoms in the molecule, in the presence of an inert solvent. Alternatively, the dimethyl sulphate may be treated with an a ,o -diamino or a ,o -bis-(methylamino) derivative of a saturated straight chain aliphatic hydrocarbon containing from 4 to 10 carbon atoms in the molecule, in the presence of an inert solvent and an alkali. The alkali is preferably an alkali metal carbonate. In the examples: (a) 1,6-diamino-n-hexane dissolved in light petroleum and sodium carbonate is added; dimethyl sulphate is added and n-hexane-a ,o -bis-trimethyl ammomium methosulphate is separated from the mixture; (b) 1,6-bis-(dimethylamino)-n-hexane dissolved in benzene is added to a mixture of dimethyl sulphate, methyl alcohol and acetic; n - hexane - 1,6 - bis - trimethylammonium methosulphate crystallizes from the mixture (c) 1,10-bis-(dimethylamino)-n-decane dissolved in benzene is added to a mixture of dimethyl sulphate and alcohol; n-decane-1,10-bis-trimethylammonium methosulphate is separated from the mixture. The bis-(dimethylamino) compounds used in examples (b) and (c) are prepared from the appropriate diamino compound by interaction with a boiling mixture of formic acid and concentrated aqueous formaldehyde.
