蓖蔴是一种植物,它的叶子可以养蓖蔴蚕,蓖蔴子可以榨油。蓖蔴油在医药方面可以作为泻剂,在工业上多用作制造润滑油。由于蓖蔴易生,每年收获蓖蔴子一次,蓖蔴蚕尚待推广,蓖蔴油价钱便宜,故将蓖蔴油用于选矿工业是很合乎经济要求的。并且在我国湖南,两广、福建等省均极易种植,所以研究加工蓖蔴油作为起泡剂是很必要的。将蓖蔴油皂化后乾馏可以得到异辛醇和辛酮——[2]及一些其他分解产物(注一),由于该二物沸点很相近,欲用分馏法将其分开得到纯的产品,是很困难的;但在选矿工业中异辛醇和辛酮——[2]照理论上说,均为很好的起泡剂,而从蓖蔴油制取该二物的混合物是很容易的,故其在选矿工业上有很好的前途。笔者以此点出发对加工蓖蔴油作为起泡剂与二号加工 Castor is a plant, its leaves can be castor silkworm, castor bean oil can be squeezed. Castor oil can be used as a cathartic in medicine and is used industrially as a lubricant. Because castor is easy to produce, castor bean is harvested once a year, castor silkworm remains to be popularized, and castor oil is cheap, so castor oil is beneficially used in the beneficiation industry. And in our country Hunan, Guangdong and Guangxi, Fujian and other provinces are extremely easy to plant, so research and processing castor oil as a foaming agent is necessary. Saponification of castor oil followed by dry distillation gives isooctanol and octanone- [2] and some other decomposition products (Note 1). Since the boiling points of the two compounds are very similar, they are separated by fractional distillation to obtain pure products. Very difficult; but isooctanol and octanone - [2] in the mineral processing industry are, theoretically, very good foaming agents and it is easy to prepare a mixture of these two substances from castor oil Its ore dressing industry has a good future. The starting point of this point on the processing of castor oil as a foaming agent and the second processing
