摘要:
A process for the preparation of 2,3-dimethylbutene-2 is disclosed, which comprises the steps of converting isovaleraldehyde to isopropylacrolein, hydrogenating .alpha.-isopropylacrolein to form 2,3-dimethylbutanol, dehydrating 2,3-dimethylbutanol to form an olefin mixture comprising 2,3-dimethylbutene-1 and 2,3-dimethylbutene-2, and isomerizing the 2,3-dimethylbutene-1 contained in the mixture into 2,3-dimethylbutene-2. The present process is technically simple and inexpensive to utilize, and results in high yields of the desired product.
