Abstract

1. Process for preparing tetramethyloxirane by reacting 2,3-dimethylbutenes which may contain up to 2% of 2,3-dimethylbutane and up to 3% of n-hexane with oxygen or an oxygen-containing gas at temperatures of 40 to 180 degrees C and residence times of 5 to 150 minutes without the addition of catalysts, characterised in that the reaction is carried out without the addition of inert solvents and the tetramethyloxirane obtained is separated off.
