Reaction Conditions

Reaction Steps

A stirred mixture of 117 g of butyl carbamate, 5 g of butanol, 15 g of ®LEWASORB AC-10 and 60 g of isobutene was heated to 70° C. in a stirred autoclave, and stirring was continued at this temperature for 4 hours. Thereafter, the catalyst was separated off and the mixture was distilled under reduced pressure. 161 g (93% of theory) of butyl N-tert.-butylcarbamate of boiling point 110°-111° C./20 mbar were obtained. No substantial amount of diisobutene was detected.
