الإجراء التجريبي

One mol (172 g) of α-naphthoic acid, 1.5 mol (195 g) of octyl alcohol and 3 ml of conc. H2SO4 were charged into a four-necked flask, and the whole was heated to 120° C. under agitation for 5 hours in a nitrogen atmosphere. After the end of the reaction, the resulting reaction mixture was cooled, freed from the water, sulfuric acid, unreacted naphthoic acid and alcohol by the use of a separating funnel and then distilled under a reduced pressure to obtain 230 g of octyl-1-naphthoate having a boiling point of 200°-202° C./4 mmHg.
