摘要:
A novel process is provided for producing a pure triaryl phosphate ester free from phenolics without creating an undesirable waste product. After recovery of the triaryl phosphate ester the reactio mixture residue is converted into an emulsion suitable for use as a flame retardant useful for application to carpets.
