titleOfInvention |
Production of a peracid and an oxirane |
abstract |
The invention provides a continuous process for the production of a peracid in an organic solvent comprising the steps of: (a) providing an aqueous phase comprising sulphuric acid, hydrogen peroxide and water; (b) providing an organic phase comprising an organic solvent and carboxylic acid; and (c) contacting said aqueous and organic phases countercurrently to produce an aqueous solution comprising sulphuric acid and water and an organic product solution comprising organic solvent and a peracid corresponding to said carboxylic acid. Desirably the process includes the added step of: (d) utilizing at least a portion of said aqueous solution to provide at least a portion of the aqueous phase of step (a). The invention also provides a continuous process for the epoxidation of an alkene comprising steps (a) through (d) with the added steps of: (e) reacting at least a portion of the peracid of said organic solution and an alkene to produce a product mixture comprising oxirane, carboxylic acid and organic solvent; (f) effecting distillation of said product mixture to produce a product phase comprising the oxirane and a recycle phase comprising carboxylic acid and organic solvent; and (g) utilizing at least a portion of said recycle phase to form at least a portion of the organic phase of step (b). |
