Abstract

297,212. Johnson, J. Y., (I. G. Farbenindustrie Akf.-Ges.). Sept. 10, 1927. Amino compounds, catalytic production of from nitro compounds and hydrogen. - The catalytic reduction of nitro compounds with hydrogen to produce aromatic amines is carried out at pressures of at least 20 atmospheres and in presence of sulphur compounds which partly poison the catalyst and so prevent the formation of undesired bye-products. The sulphur compounds may be existing impurities in the raw materials or they may be specially added. According to an example, 300 parts of crude nitrobenzene are stirred with 100 parts of Swedish spongy iron under a pressure of 140 atmospheres of hydrogen. 220 parts of aniline are obtained.
