1-isocyanato-2,2-dimethylpropane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 4520 g (40 moles) of neopentylisocyanate and 1 g of diazabicyclooctane (Dabco) are heated to 80° C. (10 l flask) and 2240 g (40 moles) of propargyl alcohol are then added in the course of 1.5 hours. When the addition of the alcohol has ended, IR spectra are used to monitor whether the reaction is complete. When the NCO band has disappeared, the mixture is distilled under a high vacuum. 6395 g (95% of theory) of 2-propinyl N-neopentylcarbamate of boiling point: 85° C./40 mbar are obtained. are then added in the course of 1.5 hours the mixture is distilled under a high vacuum
