실험 절차

EP-A 860 419, too, proposes carrying out the preparation of 2,2-dimethylolbutanal from n-butyraldehyde and formaldehyde in a plurality of stages, with the actual reaction occurring in the first stage and the 2-ethylacrolein obtained as by-product being reacted with further formaldehyde in the second stage. The 2,2-dimethylolbutanal prepared in this way can then be hydrogenated to give trimethylolpropane. Once again, no formate is isolated.
