这个实驗,我們沒有从一般的書上找到較詳細的材料,主要是根据格琳卡著:“普通化学”(重譯本)第三册第403頁上的小体字來編寫講义進行实驗的。經过多次实驗後,摸索到一點粗淺的体会,在这里提出來,請同志們指正。实驗是这样進行的: (1)用直接化合法制备鈉汞齐在蒸發皿內,先將石蜡熔成液体(其体積只要能淹沒鈉即可),去火,以免反应过猛。然後,向石蜡
In this experiment, we did not find more detailed materials from the general book, mainly on the basis of the small letters in Gelinka’s book, “General Chemistry”, Volume III, page 403, for writing handouts . After many experiments, groping a little superficial experience, put forward here, please comrades correct me. The experiment is carried out as follows: (1) sodium amalgam is directly prepared by a direct method in an evaporating dish, the paraffin is first melted into a liquid (the volume can be submerged as long as sodium), and the fire is made to avoid excessive reaction. Then, to paraffin
