ABSTRACT:
A process for producing 3-methyl-3-buten-1-ol from 3-methyl-2-pentene-1,5-diol which comprises heating 3-methyl-2-pentene-1,5-diol at a temperature between 200.degree. and 450.degree. C in the presence of isobutene.
According to a preferred embodiment, the heating step and a distillation step to separate 3-methyl-2-pentene-1,5-diol from 3-methylene-1,5-pentanediol is incorporated into a citric acid synthesis method to increase the yield of citric acid from isobutene plus formaldehyde.
