A PROCESS FOR TREATING ELEMENTAL SULPHUR FOR SMELL IMPROVEMENT

A process for treating a stream of elemental sulphur comprising an organic polysulphide and/or a thiol for smell improvement, the process comprising the following steps: (a) providing a molten stream of elemental sulphur comprising an organic polysulphide and/or a thiol at a temperature in the range of from 120 to 160°C; (b) admixing a liquid unsaturated compound with the stream of molten elemental sulphur in an amount in the range of from 0.01 to 10.0 wt% based on the weight of sulphur to allow the organic polysulphide and/or thiol to react with the unsaturated compound.
