WebMar 22, 2024 · The target product of cyclohexene was obtained through a dehydration reaction of cyclohexanol using 80% phosphoric acid as a catalyst and resulted in a 47% yield. A fractional distillation column was used to separate the cyclohexene product from the remaining phosphoric acid and impurities.
WebIn the first step, the OH group on cyclohexanol accepts a hydrogen ion from an acid. Note that any acid will work in terms of the reaction, but more common acids that are used … WebSep 19, 2024 · The acid used in this experiment is 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.
WebJan 23, 2024 · Introduction. The dehydration reaction of alcohols to generate alkene proceeds by heating the alcohols in the presence of a strong acid, such as sulfuric or phosphoric acid, at high temperatures. The required range of reaction temperature decreases with increasing substitution of the hydroxy-containing carbon: 1° alcohols: 170° … Webcyclohexyl propanoate. hydrogen chloride. This is a "Nucleophilic Addition/Elimination"-reaction.
