Claim:
1. A process for the preparation an emulsion of elemental sulphur particles, said process comprising the steps of: (a) providing a first stream, having a first stream temperature in the range of from 60 to 200° C., and comprising urea that is in liquid form; (b) providing a second stream, having a second stream temperature in the range of from 120 to 150° C., and comprising liquid elemental sulphur; and (c) mixing the first stream and the second stream in a mixing device at a mixing temperature so that the elemental sulphur and urea are maintained in substantially liquid form in the mixing device and in the presence of a multifunctional ionic surfactant to form an emulsion comprising elemental sulphur particles which are coated with a layer of the multifunctional ionic surfactant and dispersed in the urea.
