Cyclohexene from cyclohexanol
Webis 85% phosphoric acid and the alcohol is cyclohexanol. The phosphoric acid is a catalyst and as such increases the rate of reaction but does not affect the overall stoichiometry. It can be seen from the balanced reaction that 1 mole of alcohol produces 1 mole of alkene (this information is useful for percent/theoretical yield calculations). http://api.3m.com/synthesis+of+cyclohexene+from+cyclohexanol

EXPERIMENT 9: CARBOCATIONS II: PREPARATION OF CYCLOHEXENE FROM CYCLOHEXANOL INTRODUCTION: Cyclohexanol can be converted WebCyclohexanol is dehydrated to cyclohexene by heating it in the presence of a heteropolyacid catalyst. The heteropolyacid is selected from tungstophosphoric acid, tungstosilicic acid, molybdophosphoric acid and molybdosilicic acid. Tungstophosphoric acid can be improved in its catalytic performance by calcination. The dehydration reaction is …
