    Abstract: Liquid mixed triaryl thiophosphate mixtures can be prepared by forming a mixture of phenol and substituted phenols, forming a phosphite from that mixture and sulfurizing the phosphite, washing the thiophosphate with aqueous base, and drying the so washed thiophosphate under mild conditions. The products are liquid while containing at least 25 percent symmetrical triaryl thiophosphate. Colorless and odorless products are prepared.

    Abstract: Diethyl ethylphosphonate is formed by the catalytic rearrangement of triethyl phosphite in a reaction medium at elevated temperature, preferably using an ethyl iodide as the rearrangement catalyst, employing a heel of diethyl ethylphosphonate in the reaction medium when the reaction is begun with maintaining of the reaction medium at a temperature above the boiling point of the triethyl phosphite (for example, a temperature of from about 175.degree. C. to about 185.degree. C.) and addition of the triethyl phosphite to the reaction medium at a rate slow enough to maintain that temperature.

    Abstract: The neutralization of products which are phosphorus containing oligomers having ##STR1## linkages between phosphorus atoms and which are obtained by the self-condensation of .beta.-halo-alkyl esters of pentavalent phosphorus acids or by the condensation of these esters with an alkyl ester of a pentavalent phosphorus acid is accomplished by reaction with an alkylene oxide, either alone or in combination with water or an alcohol having the formula ROH where R is a C.sub.1 -C.sub.20 alkyl group, and is enhanced by heating the products with a Lewis acid to promote alcoholysis reactions between labile groups contained therein and structures formed by alkylene oxide neutralization of free acid groups. The stabilized product formed by this process gives a better cure when incorporated in a polyurethane foam.
