The mixture is stirred for 18 hours at 25° C then added to 500 parts of water. The oily product is separated into 300 parts of toluene and the solution is washed with water, dried and evaporated at 40° l C under reduced pressure to give 72 parts of nonyl-N-benzenesulphonyloxycarbamate as a colourless oil.
