Apparatus: a) 800 l. tile-lined reducer vessel fitted with a ship’s propeller type agitator, 120 RPM.
b) 3 cbm iron vessel with an anchor type agitator, 50 RPM, fitted for steam distillation.
Charge: 44 kg water. 155 kg iron powder. 4 kg hydrochloric acid, crude. 195 kg nitro Echtorange GGD, mol 259.
Process: 操作步骤: 美国人也未说明资料来源,为什么?
The water, iron powder and hydrochloric acid are added to the 800 l. reducer under agitation and heated to 100℃. At 100-102℃. 195 kg of nitro Echtorange GGD (5-nitro-1,3bistrifluoromethylbenzene) are permitted to run into the reducer slowly, i.e., as the reaction permits. This requires about 8-10 hours. After all the nitro Echtorange GGD has been added, the charge is boiled for an additional 4 hours using a reflux condenser; then sampled and tested to determine whether reduction is complete. Upon completion of the reduction the charge is run to the 3 cbm iron vessel and the reducer washed out several times with hot water. The Echtorange GGD base is then distilled off with steam and well separated.
The material distills over with water in the proportions of about 1:5. First a small portion, which is not completely soluble in hydrochloric acid, distills over as foreshot. This, determined by frequently taking of test samples, is drained off. Towards the end of the steam distillation the bse comes over slightly yellow colored. This portion is collected as second runnings and with the foreshot purified by fractional distillation at a temperature of about 185-190℃. under normal pressure. About 90% of the material obtained from portion is GGD.
The water separated from the steam distillation mixture still possesses the extraordinary unpleasant odor of the base. This water can be reused in the next charge for washing out the reducer by transferring it directly from separator.
In order to remove any traces of water which may still adhere to the base after separation, the material including suitable additional charges is heated in a kettle for some time at 100℃. until it is completely dry, and then run thru a pressure filter into 200 l. tinned-iron shipping drums.
Yield: 195 kg nitro Echtorange GGD à 154 kg Echtorange GGD base. M.W. 299. (抄注: 分子量应该是229. 说明FIAT 也有错!)。
Another process operated on a larger scale is as follows: (抄注:下面方法与BIOS 1149相同。)。
1) 1 – 4.5 cbm steam jacketed iron reducing kettle, with iron agitator, steam inlet pipe and separating device.
2) 1 – 500 l. measuring vessel. 3) 1 – filter press.
Charge: 600 kg Nitro Fast Orange GGD, B.P. 185-190℃. sp.gr. 1.55. 500 kg iron turnings. 20 kg acetic acid.
500 kg of iron turnings, 500 l. of water and 20 kg of acetic acid are charged into the reducing kettle 1) and heated to boiling. Over a period of 32 hours, with refluxing, 600 kg of Nitro Fast Orange GGD is run into the boiling iron-acid mixture in a very thin stream. After addition of all the Nitro Fast Orange GGD base refluxing is continued for an additional 6 hours and the base drawn off means of a separating device in the kettle.
Yield: 505 kg. B.P. 189℃. F.P. + 3℃. sp.gr. 1.48.

在搅拌下将44 kg水,155 kg铁粉和4 kg粗盐酸加到800 L还原锅中,加热到100℃. 在100-102℃缓缓加入195 kg硝基坚牢橙GGD(5-硝基-1,3-双三氟甲基苯),这需要8-10小时。当所有硝基坚牢橙GGD已经加入,物料用回流冷凝器再沸腾4小时,然后取样检验沉淀还原是否完全。还原完成后物料流入3000 L铁锅中。并将还原锅用热水洗涤数次。然后水蒸汽蒸馏出坚牢橙GGD色基,并很好分离。
蒸出的胺和水的比例约为1:5。 最初的一小部分并不溶解于盐酸,一般是另收的。水蒸汽蒸馏趋于末期,胺的颜色转为微黄。这一部分和最初的馏出物在常压和185-190℃进行精馏,由精馏得到的90%为GGD色基。
蒸汽蒸馏分离出的水仍带有胺的不愉快气味,这种水可用于下一批洗涤还原锅。 为了除去附着在胺上的任何痕量的水。在分离后在锅中加热至100℃,直至完全干燥。 195 kg硝基坚牢橙GGD生成154 kg坚牢橙GGD色基。
