ABSTRACT:
Production of tertiary hydroxyalkylphosphine oxides of general formula (I) ##STR1## in which R.sup.1 and R.sup.2 each stand for organic groups having from 1 to 18 carbon atoms, where R.sup.1 may be identical with R.sup.2 and R.sup.2 may be identical with R which stands for a radical of general formula (II) ##STR2## in which R.sup.3 and R.sup.4 equally stand for organic groups having from 1 to 18 carbon atoms and/or more preferably for hydrogen. The compounds are made from phosphines of general formula (III) ##STR3## in which R.sup.3 and R.sup.4 have the meanings given above, which are reacted in a single step operation with carbonyl compounds of general formula (IV) ##STR4## in which R.sup.3 and R.sup.4 equally have the meanings given above. The reaction is effected while adding at least one substance yielding hydroxyl ions and in the presence of water, and the resulting hydroxyalkylphosphine oxides are separated from the reaction product.
