Abstract
This paper investigated several influencing factors for the preparation of solid alcohol, including the amount of raw materials used such as stearic acid and copper nitrate and so on, and the temperature, etc. Through single factor experiments, the main influence factors of preparing solid alcohol were determined. And, on this basis, in view of three remarkable influence factors: the stearic acid amount used, the copper nitrate amount used and the temperature, the orthogonal experiment was carried out. Finally, the optimal preparation conditions were determined as follows: 25ml industrial alcohol, 1.3g stearic acid, 1.2ml 10% copper nitrate solution, at 75°C, pH 8, the cooling way is gradual cooling with no refluxing.
