Reaktionsbedingungen

Temperatur
60 °C

Versuchsvorschrift

0.05 g of 2,6-di-tert-butyl-4-methylphenol, 0.02 g of Desmorapid Z, 26.7 g of 3-(methylthio)phenyl isocyanate were initially introduced into a 250 ml round-bottomed flask and heated to 60° C. Thereafter, 23.3 g of 2-hydroxybutyl acrylate were added dropwise and the mixture was kept further at 60° C. until the isocyanate content had fallen below 0.1%. Thereafter, the ethyl acetate was distilled offat 5 mbar and cooling was effected. The product was obtained as a crystalline solid.
