Abstract
A process for the recovery of materials suitable for recycle to the manufacture of alkoxy or aryloxyphosphazenes including, inter alia, solvents, hydroxy compounds, acid acceptors and the like, from flash distillation of the washed phosphazene product together with a second vapor stream produced from the aqueous wash of the crude phosphazene product, whereby an aqueous phase and an organic phase are produced and recyclable materials are extracted from the aqueous phase into the organic phase, separating the organic phase from the aqueous phase and separating the organic phase into components by conventional methods which are suitable recycle streams for the phosphazene product manufacturing process.
