実験手順

1 l of t-butyl methyl ether and 1.05 l of 3N methyl magnesium chloride solution were placed under N2 in a 41/2 l sulphonation flask having a thermometer, stirrer and dropping funnel and 456 g of geranial in 500 ml of t-butyl methyl ether were added dropwise at 0° C. The mixture was stirred at 10° C. for 1 hour and poured on to 3 kg of ice and 500 g of NH4Cl and treated with 1 l of hexane. After mixing well the H2O phase was separated and washed neutral 3 times with 500 ml of NH4Cl solution, dried and evaporated.
