Abstract

Crude dipentaerythritol hexaorthophosphate is produced by heating in the absence of moisture a mixture consisting of substantially one molecular part of dipentaerythritol and substantially two molecular parts of orthophosphoric acid and of phosphorus pentoxide. A solution of the crude product is used for flame proofing combustible cellulosic materials impregnated with a polyethyleneimine (see Group VIII). In an example, the crude product is prepared by adding orthophosphoric acid to phosphorus pentoxide, cooling, adding dipentaerythritol and heating the mixture at 120-140 DEG C. The product probably contains phosphoric acid and lower orthophosphate derivatives of dipentaerythritol in addition to the hexaorthophosphate. Specification 560,173 is referred to.
