water and 15 kg. Formic acid. The mixture is brought to the boil and 4000 kg.
iron borings added at such a rate as to maintain the desired rate of reaction.
15 kg. Formic acid is added when 2000 kg. iron borings has been added or when
the reaction tends to slow down. Time of addition of iron borings: 10-12 hr.
After completion of reduction 800 l. solvent naphtha is
added to obtain a better separation than is possible by steam distillation.
After a settling period of 1/4 hr. the naphtha layer is
drawn off to the agitated settling cylinders. The iron oxide is extracted a
further two or three times with 800 l. naphtha per extraction. The naphtha
extracts are combined after a further period of settling and filtered. Solvent
naphtha is removed by live steam distillation and the 4-chloro-o-anisidine
water mixture then worked up by vacuum distillation. On account of the
instability of 4-chloro-o-anisidine only small charges are distilled at a time.

4-Chloro-o-anisidine Pure. 抄录如下。
Crude 4-chloro-o-anisidine from the iron reduction
process contains approx. 4% impurities and these are removed by naphtha crystallization
and washing.
80 parts by weight 4-chloro-o-anisidine crude and 20
parts by weight solvent naphtha are heated to obtain solution and then cooled
slowly to 200C. in approx. 20 hr. The mother liquor is then run off
from the bottom of the crystalliser and then crystal mass washed with 10 parts
by weight of fresh naphtha. After draining off the washings the pure
4-chloro-o-anisidine is melted up and run into the still where naphtha is first
removed and the pure product then distilled over. The still charge should not
be greater than 500 kg. 4-chloro-o-anisidine due to the instability of the
latter. The naphtha mother liquors are discarded after recovery of naphtha by
steam distillation.

4-氯邻氨基苯甲醚(粗品): 4000 kg 4-氯邻硝基苯甲醚加到1500 kg水和15 kg1甲酸中,混合物加热至沸,并加入4000 kg 铁屑,加入速度在于保持希望的反应速度。当加入2000 kg铁屑或反应趋于缓慢时,再加入15 kg甲酸,甲铁屑时间10-12小时。
还原完毕,加入800 L溶剂石脑油,比蒸汽蒸馏可以得到较好的分离。静置15分钟后,将石脑油层排出。氧化铁用石脑油萃取2-3次,每次用800 L,石脑油萃取物合并,静置,过滤。水蒸汽蒸馏除去石脑油,然后将4-氯邻氨基苯甲醚 – 水混合物真空蒸馏处理。考虑到4-氯邻氨基苯甲醚的不稳定性,每次仅蒸馏小批量。4-氯邻氨基苯甲醚粗品熔点790C.
每吨4-氯邻氨基苯甲醚消耗:4-氯邻硝基苯甲醚1280 kg,铁屑1250 kg,甲酸10 kg,石脑油1000 kg(未计算回收)。
4-氯邻氨基苯甲醚(纯品): 铁粉还原法制备的4-氯邻氨基苯甲醚含有4%杂质,将其用石脑油重结晶除去杂质。 80份4-氯邻氨基苯甲醚粗品和20份溶解石脑油加热得到溶液,然后于约20小时内缓缓冷却到200C。母液由结晶器底部流出,然后结晶用10份新石脑油洗涤,放出洗涤溶剂后,纯的4-氯邻氨基苯甲醚熔融送往蒸馏釜,先蒸馏除去石脑油,然后蒸出纯的产品。蒸馏釜加入量应不大于500 kg,因为4-氯邻氨基苯甲醚不稳定。石脑油母液在水蒸汽蒸馏回收石脑油后弃去残液。粗品1170 kg回收1吨纯品,石脑油净耗100 kg。4-氯邻氨基苯甲醚熔点810C.

资料全部抄自染料生产工艺汇编。未注明资料来源。 但它是正式出版物!如果说,英国人,美国人不说明资料来源,它至少是把德文译成英文了,
这里抄录德文的英文译文以及英文译文的日文译文和中文译文,其目的是希望读者学点外文,尽量要能看懂外文,否则人家译多少,你只能看多少,译错了,你也没有办法。不同译文可以各取所需,我是全抄(只是手头无德文原件),目的是请读者看看人家是这么编写生产工艺的(当然,这已是过去的历史资料)。
