The preparation of solid alcohol has been studied.The optimum ratio between alcohol:stearic acid and NaOH has been determined to be 92.5∶6.5∶1, and reaction temperature to be 60 ℃. The solid alcohol prepared under this condition has a melting point of 52 ℃, and the solid alcohol of 150 g burns in solid state continuously for 114 min. Various influences on the properties of solid alcohol have been discussed.
