Abstract
Trimethylolpropane is produced by a process comprising continuously reacting butyraldehyde, formaldehyde and sodium hydroxide in an aqueous medium, there being present at least 6 mols. of formaldehyde per mol. of butyraldehyde, to produce a solution containing trimethylol-propane and sodium formate, and recovering trimethylolpropane from this solution. Preferably the solution containing the trimethylolpropane and sodium formate is treated to reduce its pH to 6.8 or lower by the addition of acidic materials, e.g. formic, acetic, sulphuric or phosphoric acid. The formaldehyde is then distilled off and the trimethylolpropane is recovered from the residual solution. The formaldehyde and sodium hydroxide are desirably supplied to the mixing zone as aqueous solutions. Preferably 1.1 to 1.2 mols. of sodium hydroxide per mol. of butyraldehyde is used. For optimum results the temperature of the mixture should rise to a peak within the range 50 DEG to 60 DEG C. and advantageously the reactor is operated adiabatically. The trimethylolpropane may be recovered from the reaction mixture by the process described and claimed in Specification 816,208.
