実験手順

1 mol of phenoxyethanol is esterified azeotropically in the presence of 1.1 mol of H3PO3 in xylene on a water separator. The reaction product which precipitates on cooling is filtered off, washed with petroleum ether and dried to give a white powder. The amount of the phosphoric diester (2-phenoxyethanol hydrogensulphate, 0-50%) which may be formed in this reaction in addition to phenoxyethanol phosphate (phenoxyethanol dihydrogenphosphate) does not interfere in the polycondensation which subsequently takes place; it is also incorporated into the polycondensate.
