実験手順
According to the prior art methods, production of β-methyl-δ-valerolactone and 3-methylpentane-1,5-diol requires respective independent production facilities. On the contrary, the simultaneous production method can produce β-methyl-δ-valerolactone and 3-methylpentane-1,5-diol simultaneously from 2-hydroxy-4-methyltetrahydropyran with a common reactor and under relatively mild conditions. According to this simultaneous production method, β-methyl-δ-valerolactone and 3-methylpentane- 1,5-diol are produced generally in a β-methyl-δ-valerolactone/3-methylpentane-1,5-diol mole ratio of about 70/30 to 15/85. Said simultaneous production on method can give β-methyl-δ-valerolactone and 3-methylpentane- 1,5-diol each in a satisfactory yield and in a yield ratio therebetween selected depending on the demands therefor.
