    • The present invention provides a process for the production of the triple salt 2KHSO.sub.5.KHSO.sub.4.K.sub.2 SO.sub.4 from sulphuric acid, hydrogen peroxide and potassium hydroxide, wherein, for continuous production, an aqueous working solution which contains KHSO.sub.5, sulphuric acid and potassium sulphate in a molar ratio of 1.3 to 2.5/1.2 to 2.0/1, is concentrated in an evaporation plant under reduced pressure and at a temperature of maximum 40.degree. C. to a concentration which corresponds to a content of 20 to 30% by weight of KHSO.sub.5, a partial stream is removed from the concentrated solution and from this, by cooling to a temperature below 15.degree. C., the triple salt is precipitated and separated, the mother liquor obtained is combined with the remaining solution, the solution is reconstituted by the addition of 90 to 100% sulphuric acid, 30 to 90% hydrogen peroxide and concentrated aqueous potassium hydroxide solution and recycled to the evaporation plant.
    • 本发明提供了从硫酸,过氧化氢和氢氧化钾制备三重盐2KHSO5.KHSO4·K2SO4的方法,其中,为了连续生产含有摩尔浓度的KHSO 5,硫酸和硫酸钾的水溶液 的比例为1.3〜2.5 / 1.2〜2.0 / 1,在蒸发装置中减压浓缩至最高40℃,浓度相当于KHSO 5的20〜30重量%, 从浓缩溶液中除去部分物流,并通过冷却至低于15℃的温度,将三重盐沉淀并分离,将得到的母液与剩余溶液混合,通过加入 90至100%硫酸,30至90%过氧化氢和浓缩的氢氧化钾水溶液,并再循环至蒸发设备。

    • AND HYDROGEN PEROXIDE WHEREIN R AND R1 ARE ALKYL GROUPS HAVING FROM 1 TO 6 CARBON ATOMS AND R2 IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND ALKYL GROUPS HAVING FROM 1 TO 6 CARBON ATOMS. WHEN THE REACTION IS CONDUCTED IN THE PRESENCE OF AN ORGANIC DILUENT IN WHICH THE REACTION PRODUCT IS INSOLUBLE, IT IS DESIRABLE TO USE CONCENTRATIONS OF HYDROGEN PEROXIDE IN EXCESS OF 50% W./W. AND THE USE OF SUCH DILUENTS IS DESIRABLE DUE TO THE FORMATION OF A GRANULAR PRODUCT. THE REACTION MAY ALSO BE CONDUCTED IN THE PRESENCE OF AN ORGANIC SOLVENT SUCH AS AN ORGANIC ACID CORRESPONDING TO THE DIKETONE REACTANT WHICH DISOLVES THE DIOXOLANE PRODUCT. THE USE OF AN ORGANIC SOLVENT IS ADVANTAGEOUS FOR PRODUCING SUBSTANTIALLY PURE PRODUCTS WITH MINIMUM PURIFICATION. THE 3,5-DIHYDROXY1,2-DIOXOLANES ARE USEFUL IN THE POLYMERIZATION OF VINYL COMPOUNDS OR IN THE CROSS-LINKING OF UNSATURATED POLYESTER RESINS.
