2,5-Dimethyl-2,4-hexadiene is prepared by dehydrating 2,5-dimethyl-2,5-hexanediol in liquid phase. The reaction takes place by contacting 2,5-dimethyl-2,5-hexanediol, melted or dissolved in an appropriate solvent, with acids, heating the mixture at a temperature of 100 DEG C.-160 DEG C. and distilling off water from the reaction environment as it is being formed. The pressure can range between 1 and 10 bars. |
