煤酚皂溶液(來蘇兒)中的煤酚含量测定,現在多採用水蒸氣蒸溜法,此法在操作上甚不方便,且有一定條件限制,時間較長、手續繁多,且結果不準確。經我們多次研究及實驗後,認爲下法甚爲簡便,且比較准確,又節省時間。特介紹出來,以供參考。儀器:1.100—150毫升分液漏斗一個。2.50毫升蒸溜燒瓶一個(或用同容積的圓燒瓶代之,導管可在瓶口上接出)。3.粗厚玻管一根(長約0.5米,直徑1.5—2厘米,也可用壞了的滴定管代替)。4.
The determination of the content of coal phenols in coal phenolic soap solution (Lai Suer) is now widely used steam distillation method, this method is inconvenient in operation, and there are certain conditions, a long time, a lot of procedures, and the result is not accurate . After many studies and experiments, we believe that the method is very simple, accurate, and saves time. Specially introduced for reference. Instrument: 1.100-150 ml separatory funnel. 2. One 50 ml distilled flask (or a round flask of the same volume instead. The tube can be received at the mouth of the bottle). 3. A thick glass tube (about 0.5 meters long, 1.5-2 cm in diameter, can also be replaced with a broken burette). 4.
