Abstract
A process for producing neopentyl glycol is disclosed which comprises reacting isobutyraldehyde and formaldehyde in the presence of a trialkylamine catalyst to form a condensation reaction product comprising hydroxypivaldehyde, followed by hydrogenation of the hydroxypivaldehyde in a hydrogen gas sparged reactor in the presence of a Raney nickel catalyst. This process minimizes unwanted by-products, and does not have to be carried out under high pressure as do certain prior art methods.
