Reaktionsschritte
The above crude product of 4-(1-methyl-heptyloxy)-4'-hydroxy-azobenzene (16.5 g) was heated with lauryl bromide (16 g) in ethanol in the presence of KOH (3.6 g) under reflux for 10 hours, followed by passing a toluene solution of the product through an alumina chromatographic column and recrystallizing from heptane to obtain 4'-dodecyloxy-4'-(1-methyl-heptyloxy)-azobenzene
