Abstract
Trimethylol alkanes are prepared by reacting at least three moles of formaldehyde with one mole of a C2 to C20 saturated aliphatic aldehyde having at least 2 a -carbon atoms, and at least one equivalent of a base at 5-80 DEG C., the rate of addition of base being such as to maintain a pH of 7-13 in the reaction mixture until addition of the higher aldehyde is substantially complete, and the rate of addition of higher aldehyde being such as to maintain a free higher aldehyde concentration of below about 25% based on the total higher aldehyde employed. The base may be an alkali metal hydroxide, suitably used in aqueous solution. In examples, butyraldehyde is converted into trimethylol propane and generally, RCH2CHO gives RC(CH2OH)3.
