반응 단계
1040 g (10 moles) of freshly distilled methional, 650 g (10.5 moles) of ethylene glycol, 400 cc of benzene, 800 cc of dioxan and 10 g of p-toluene sulphonic acid are heated under reflux until the azeotropic entrainment of the water formed during the reaction, which takes 2 hours, is over. The acid medium is then neutralised by the addition of 10 g of dry sodium carbonate, after which the solution is concentrated to dryness in a water pump vacuum.
