- ORGANOPHOSPHORUS CHEMISTRY. 2. THE REDUCTION OF QUINQUEVALENT PHOSPHORUS TO THE TRIVALENT STATE
-
Phosphoryl and phosphonyl chlorides are reduced conveniently to the monobasic acid forms of the corresponding phosphorous and phosphonous acids by the use of sodium borohydride dispersed in dioxane.

- Phenolic ester synthetic resin stabilizers
-
New ortho-alkylhydroxybenzylpropanediol compounds of carboxylic acids, aldehydes, ketones, phosphites, phosphates, and phosphonates are disclosed. The propanediol compounds have in the molecule from one to four preferably from one to three ortho-alkylhydroxybenzylpropanediol units, each of which carries one to two ortho-alkylhydroxybenzyl groups, and are highly effective stabilizers for a variety of synthetic resins. Stabilizer compositions comprising a orthoalkylhydroxybenzylpropanediol compound and a known polymer stabilizer, as well as synthetic resins stabilized with such stabilizer compositions, are also disclosed.
