Sulfuric Acid → Carvacrol

참여 물질

반응 단계

Aqueous 0.5M sulphuric acid (25 ml), Teric N100 emulsifying agent (a product of ICI; 2.5 g) and carvone (50 g) were stirred and the emulsion passed through the CMR four times (15.5 ml/min, 165°-75° C., 690-760 kPa). Analysis was again by GC after each pass. After four passes a conversion of 50% was obtained. This experiment was then repeated using 1M sulphuric acid, and was directly comparable with experiment (a) above, the variation being the addition of the emulsifying agent. After four successive passes, the percentage of carvacrol obtained was 32%, 63%, 73% and 83%, with negligible by-product formation.
