Claims
- 1. A process for preparing 2,3-dimethyl-2,3-butandiol which comprises introducing into a reaction vessel containing formic acid at 50.degree. to 70.degree. C. while stirred, 2,3-dimethylbutene and hydrogen peroxide, said 2,3-dimethylbutene and hydrogen peroxide being introduced into said formic acid simultaneously but separately and thereafter hydrolyzing pinacol monoformate so formed.
- 2. A process according to claim 1, wherein said 2,3-dimethylbutene comprises a mixture of 2,3-dimethylbutene-2 and up to 30% by weight of 2,3-dimethylbutene-1.
