The preparation was carried out as in Example 2 but using 250 g of ethylene carbonate, 90 g (1.55 mol) of potassium fluoride and 162.6 g (1.0 mol) of cyclohexyl chloroformate. After addition of the chloroformate, stirring of the mixture was continued for 45 minutes at 45° C. Evaporation under vacuum was carried out as above. By distillation under reduced pressure, 122.7 g (84% yield) of cyclohexyl fluoroformate with a boiling point of 55-56° C. at 22 mm Hg were obtained.
