Reaktionsschritte

Powdered decane-1,2-diol (0.25 moles) is stirred at room temperature and very well powdered sodium hydroxide (0.25 moles) is added in portions. Gentle heating of the mixture to 55° C. gives a viscous yellow paste. Sodium chloroacetate (0.25 moles) is now added in portions over 10 minutes. The white mobile paste produced is stirred at 70°-60° C. for 1.75 h. After cooling to 20° C., 100 ml of petroleum ether is added followed by water. After separation of phases (aided by acetone) the aqueous phase is run off and acidified to pH 1.5 using 98% sulphuric acid. The oil produced is taken up into 2×375 ml diethyl ether which is then dried and evaporated to leave the title product as a clear oil (63%).
