    CPC classification number: C07F9/098

    Abstract: A PROCESS HAS BEEN PROVIDED FOR PRODUCING NEUTRAL POLYPHOSPHORIC ACID ESTER DERIVATIVES WHICH COMPRISES REACTING AN ACID ESTER WITH PHOSPHORUS PENTOXIDE AT A TEMPERATURE WITHIN THE RANGE OF-78*C. TO - 140*C. IN THE ABSENCE OF MOISTURE AND IN A MOLE RATIO OF ESTER TO PHOSPHORUS PENTOXIDE FROM 0.05 TO 9 MOLES ESTER TO 1 MOLE PHOSPHORUS PENTOXIDE, SAID ACID ESTER BEING DEFINED BY THE GENERAL FORMULA
