Plant:3 1600 l. wrought-iron agitated vessels. 1 Ammonia absorption colum. 1 Press.
1 10000 l. tiled blow-egg.
Process:1000 l. water, 900 kg. ammonia liquor ≈ 252 kg. 100% NH3, 3622 kg. 4-chloronitrobenzene-3-suphonic acid paste ≈
700 kg. NaNO2 and 4860 kg. ammonia liquor ≈ 1360 kg. 100% NH3. Total 10382 kg.
The vessel is charged with 1000 l. of water (or wash liquor; see below) and 900 kg. of ammonia liquor and the p-chloronitrobenzene sulphonic acid added with agitation. The remaining quantity of ammonia (5400 l.= 4860 kg.) is then charged, the vessel closed and heated to 1000 in 5 hours, and after waiting for rise in temperature due to the heat of reaction, it is further heated to 1200 (6 atm. pressure). The batch is held 30 hours, under these condition.
It is cooled with agitation to 600 and the residual pressure of 2 atm. released carefully through the ammonia absorption system. The temperature is raised to 1000 to distil off the remaining ammonia, and the bound ammonia also liberated by the addition of 1500 l. of milk of lime (= 300 kg. CaO).
After distillation of all the ammonia, the batch is diluted with wash liquor from a previous residue to 10000 l., filtered at 900 through a press, salted hot with 1200 kg. of salt, cooled to 180, filtered, and the cake washed with 1000 l. of 20% salt solution.
The residue in the press is charged into 2000 l. of water, boiled with direct steam and re-filtered. The filtrate is used as the water charge for the next batch or for dilution of the finished batch prior to isolation. Yield: 4480 kg. act. wt. = 672 kg. NaNO2 = 96% theory.
p-Nitroaniline-2-sulphonic acid extra:
The crude product is charged into 4000 l. of hot water or to the wash-liquor from the press residues, dissolved at 950 with agitation, filtered through a filter-press, and cooled to 150C. It is dropped to a nutsche, washed with 1000 l. of 20% brine and pulled as dry as possible. Yield: 4300 kg. act. wt. = 645 kg. NaNO2 = 92.1% theory (overall on 4-chloronitrobenzene-3-sulphonic acid).

中文摘译文。张澍声《精细化工中间体工业生产技术》1996年。P. 172. 译自BIOS 1153,189. 抄录如下。
在1600 L熟铁搅拌锅中加入1000 L水(或洗水,见下)和900 kg 氨水(含252 kg 100% 氨),在搅拌下加入3622 kg 4-氯硝基苯-3-磺酸滤饼(相当于700 kg NaNO2),其余的4860 kg 氨水(含1360 kg 100% 氨)再加入。闭锅,于5小时内加热到1000C,待反应热使温度升高后,再加热到1200C, 压力6巴。在此条件下保持30小时。
搅拌冷却到600C,通过氨吸收系统仔细释放残留的2巴压力。升温至1000C以蒸馏出残留的氨,加入1500 L石灰乳(含300 kg CaO)则结合氨也释放出来。
蒸馏出所有的氨后,反应物用上批留下的洗水稀释至10000 L,在900C压滤,滤液趁热用1200 kg 食盐盐析,冷却到180C,过滤,滤饼用1000 L 20% 食盐溶液洗涤。
滤渣放入2000 L水中,用直接蒸汽煮沸,再过滤。滤液用于下一次作为加料水或作为稀释水。得到4480 kg 4-硝基苯胺-2-磺酸滤饼,相当于672 kg NaNO2, 收率96%。
4-硝基苯胺-2-磺酸的精制是将上述粗产品加到4000 L热水或压滤的洗水中。在950C搅拌溶解,压滤,冷却到150C使其沉淀,抽滤,用1000 L 20% 食盐水洗涤,尽可能抽干。得到4300 kg滤饼,相当于645 kg NaNO2 , 以4-氯硝基苯-3-磺酸计,总收率92.1%。

加注:
本人所抄录的资料,主要是供读者参考,同时要再次说明,这些资料一般是无法找到的,而且过去的资料没有CAS编号,商品名也比较复杂。因为这是新的方式,我想利用它整理出来比较好。
现在有条件将缩微胶卷放大,变成可读式,如果上述类似资料有用,请读者提出来。
