| Place a 1000ml Pyrex beaker into a pan of water and rest this on a hotplate. Add 140ml of glacial acetic acid and 32g of 80-100 mesh catalytic iron. Heat to about 85℃, just below the point where white salts begin to appear, then add 10-15g of 1 dissolved in 75ml of glacial acetic acid. Add slowly, allowing a vigorous reaction free from excessive frothing. Continue heating for 1.5 hours after the addition. The surface will crust up, turn whitish, and climb the walls of the beaker. Remove from heat, mix into 2000ml of clean water. Add enough concentrated lye solution to neutralize the acid, then extract with methylene chloride and distill exactly as above.. |

| 將一個1000毫升Pyrex燒杯放入水,然后放置在電爐上。加入140毫升的冰醋酸,32 g的80 - 100目催化鐵。加熱到約85℃,低于此溫度白色的鹽晶體開始出現(xiàn),然后添加10-15g在75毫升的冰醋酸中溶解。緩慢增加,可以讓劇烈反應(yīng)自由從過度沸騰開始。繼續(xù)加熱,至加入后1.5小時。當(dāng)燒杯表面起殼,至白色的鹽晶體覆蓋表面。從火上移開,加入2000毫升的干凈的水混合。添加足夠的濃堿液以中和酸,然后用二氯甲烷提取,完全按照以上步驟蒸餾. |

在裝有水的鍋里放置一個1000ml的耐熱容量瓶,將鍋放在加熱板上。在容量瓶中加入140ml冰醋酸和32g80-100目大小的鐵粉。將鍋加熱至水溫大約85攝氏度。剛出現(xiàn)白色鹽,然后加10-15g75ml溶解1的冰醋酸,緩慢地加入,避免劇烈的反應(yīng)生出額外的泡沫。加完之后,繼續(xù)加熱1.5小時。反應(yīng)液表面會出現(xiàn)一層硬膜,發(fā)白,沾在瓶壁。將容量瓶從加熱處取出,混合入2000ml蒸餾水。加足夠的強堿,中和酸,用亞氯化物析取,如上精確提取。 第一次翻譯,其中不準(zhǔn)確處很多,希望樓主諒解,我的僅供參考,拋磚引玉吧。晚安。 [ 發(fā)自手機版 http://www.gaoyang168.com/3g ] |
