Procedure

To a mixture of 34.6 g. (0.25 moles) of diethyl phosphite, 50 ml. of water and 50 ml. of ethanol a mixture of 67.4 g. (0.25 moles) of octadecyl amine and 70 ml. of ethanol is added. The reaction mixture is refluxed for 4 hours, whereupon the solvent is distilled off in vacuo. 88.5 g. (93.2%) of octadecyl-ammoniumethyl phosphonate are obtained, melting at 54° to 56° C.
