Procedure

In a 250 ml round-bottomed flask, 0.02 g of Desmorapid Z, 34.1 g of n-butyl isocyanate were initially introduced and heated to 60° C. Thereafter, 15.9 g of ethanol were added dropwise and the mixture was further kept at 60° C. until the isocyanate content had fallen below 0.1%. Thereafter, cooling was effected and the product was obtained as a clear liquid.
