[交流] 求一段化工翻译谢谢~!

Cover the pill mass with three times its volume of dry acetone. Slowly bring to a gentle boil, with constant stirring. Boil for five minutes, allow to settle, decant. Continue with acetone boils until the decanted acetone is clean. Test for contaminants by adding water to decanted acetone and observing whether adulterants precipitate out. If so, continue acetone boils until acetone until it decants clear without adulterant precipitating with the addition of water. Expect three boils to be sufficient, depending on pill content and operator technique

Cover the pill mass with three times its volume of dry acetone. Slowly bring to a gentle boil, with constant stirring. Boil for five minutes, allow to settle, decant.
将药丸用3倍体积的无水丙酮浸没。持续搅拌并缓缓加热至微沸，保持微沸5分钟，静置，倾去上清液。
Continue with acetone boils until the decanted acetone is clean. Test for contaminants by adding water to decanted acetone and observing whether adulterants precipitate out.
继续加入无水病痛煮沸，直到倒出的上清液澄清。往倒出的上清液中加入水观察有无假性沉淀，进行污染物的检测。
If so, continue acetone boils until acetone until it decants clear without adulterant precipitating with the addition of water.
如果有，嘉许用丙酮煮沸直到上清液澄清并且加入水后不产生假性沉淀。
Expect three boils to be sufficient, depending on pill content and operator technique
丙酮煮沸次数一般三次就够了，但是具体次数需要根据药丸成分以及操作者技术能力决定。
