发明名称 AN AQUEOUS METHOD TO PREPARE CYCLOPROPYL METHYLKETONE FROM ACETYL-PROPANOL
摘要 An entirely aqueous method to prepare cyclopropyl methylketone from acetyl-propanol. The method is practiced by (1) forming a mixture of acetyl-propanol and an aqueous hydrogen halide, (2) distilling the mixture and returning at least a portion of the distillate that is aqueous to the distilland, (3) recovering 5-halo-2-pentanone from the distillate, and (4) reacting the 5-halo-2-pentanone with a basic solution that is from about 1-wt % to about 25-wt % base and about 75-wt % to about 99-wt % water to yield cyclopropyl methylketone.
