Claims3
A process for the preparation of a hydrocarbyl-substituted chloramine of the formula ClNR.sub.1 R.sub.2, wherein R.sub.1 is hydrocarbyl and R.sub.2 is selected from hydrogen and hydrocarbyl, by reacting chlorine monoxide, produced by reacting an alkali metal hypochlorite or an alkaline earth metal hypochlorite with carbon dioxide, with a primary or secondary amine of the formula NHR.sub.1 R.sub.2, wherein R.sub.1 and R.sub.2 are as defined above, the reaction being carried out in a non-aqueous reaction medium and without co-production of an amine hydrochloride salt.
