Phosphoric Acid → 1-Propanol, 3,3',3''-phosphinylidynetris-

Participants

Reaction Steps

The effect of concentrated phosphoric acid in amounts of 1 to 2.5 weight percent was determined by reacting in an autoclave (10.4 g, 0.05 mole) of tris-(3-hydroxypropyl) phosphine, concentrated phosphoric acid (0.15, 0.14 and 0.06 ml of 86% aqueous solution) and 1 ml of water. The yields of tris(3-hydroxypropyl) phosphine oxide after 4.5 to 5 hours at temperatures between 150° C. and 180° C. is summarized in Table III.
