A method of recovering uranium from phosphoric acid solutions containing same comprises extracting the uranium from the phosphoric acid with an organic solution of an alkylphenyl pyrophosphate.

Method for the recovery of uranium from wet-process phosphoric acid

Textiles are rendered flame retardant by incorporating a phosphorus flame retardant prepared by a two step process having as essential steps:

Textiles containing a poly(oxyorganophosphate/phosphonate) flame

The viscosity of filled unsaturated polyester resin compositions is reduced by the incorporation in said compositions of an effective amount of a composition comprising a lower alkoxylated alkyl acid phosphate ester.

Filled unsaturated polyester resin compositions

The viscosity of filled unsaturated polyester resin compositions is reduced by the incorporation in said compositions of an effective amount of an organic phosphite ester for viscosity reduction.

Filled unsaturated polyester resin compositions having lowered

Phosphorus containing flame retardants are prepared by a two step process having as essential steps:

Polyurethanes containing a poly (oxyorganophosphate/phosphonate) flame

Poly (oxyorganophosphate/phosphonate) and process for preparing

Novel phosphonxycarboxamides of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are selected from the group consisting of aryl and alkyl having from 1-6 carbon atoms and may be the same or different; R.sup.3 represents hydrogen or --CH.sub.2 OH; R.sup.4 represents hydrogen, --CH.sub.3, --CH.sub.2 OH, or --C.sub.2 H.sub.4 OH, R.sup.5 represents an alkyl group having from 1-5 carbon atoms; and n represents 1 or 2 are useful as flame retardant agents for textile materials.
