ABSTRACT:
Included are the title phosphorate compounds, and a process to prepare them comprising contacting a carbylphosphorate mono acid halide with a carbyloxide. For example, ((2-(3-bromo-2,2-bis(bromomethyl)propoxy)ethyl(chloroethyl)-(ethyl))phosph orate can be prepared with (2-(3-bromo-2,2-bis(bromomethyl)propoxy)ethyl)(ethyl)-chloridophosphorate and ethylene oxide. The compounds are useful so-called flame-retardants for polyurethanes, especially flexible foams because, for example, substantially non-scorching and non-odoriferous flame-retardant flexible foams can be readily prepared with the compounds.
