ABSTRACT:
Trimethylolpropane of high purity is efficiently made by mixing the aldol reaction product of formaldehyde and n-butyraldehyde with at least about 20 wt % of a lower alcohol prior to hydrogenation. The alcohol addition also promotes hydrogenolysis of by-product esters at pressures below 3000 psig and allows recovery of high purity product by simple distillation.
