Process for the preparation of oxiranylcarbonic esters |
| abstract |
Preparation of oxiranyl carboxylic acid esters from unsaturated carboxylic acid esters by epoxidation with hydrogen peroxide in an aqueous-organic two-phase system in the presence of a catalyst made from an alkali tungstate, tungstic acid or tungsten (VI) oxide, phosphoric acid and a quaternary ammonium or phosphonium salt, by the reaction in the presence of 1 to 2 moles of hydrogen peroxide per mole of carboxylic acid ester and at a pH of the aqueous phase between about 2 and 4. |
