摘要: A method for decolorizing and stabilizing alkylphenyl esters of phosphoric acid which comprises contacting the esters with an effective amount of a benzofuranone (e.g., is 5,7-di-t-butyl-3-(3,4 di-methylphenyl)3H-benzofuran-2-one) for a sufficient length of time to decolorize and stabilize the esters against subsequent color formation.

摘要: An improved process for phosphite rearrangement wherein the phosphite is rearranged to the phosphonate. The improvement comprises conducting the phosphite rearrangement reaction in an aliphatic solvent which is miscible with the reactants at reaction temperatures, and immiscible with the product at lower temperatures. Increased yields of the phosphonate product are obtained without the need for additional distillation for solvent separation.
摘要翻译: 亚磷酸酯重排的改进方法,其中将亚磷酸酯重排为膦酸酯。 改进之处在于在脂肪族溶剂中进行亚磷酸酯重排反应,其在反应温度下可与反应物混溶,并且在较低温度下与产物不混溶。 获得了增加的膦酸盐产物的产率,而不需要额外的蒸馏用于溶剂分离。
