摘要

Process for obtaining 4 (para-amino methyl) benzoic acid comprising the preparation of the catalyst for one of the phases, characterized in that it prevents the separation of the process in two phases of operations, of which the first part of the para-amino benzoic acid and it ends in the obtaining of the 4-cyano benzoic acid and the second part of the result of the previous one and it ends in the 4 (para-amino methyl) benzoic acid and because in the first phase mentioned, molybdenum trisulfide is used as a transformation reagent and in the second, catalytic hydrogenation is used by using a catalyst prepared starting from an 8% solution of freshly prepared sodium hydroxide with a temperature maintained at 50 + 2ºC 6.2% of an alloy is added slowly to equal parts of nickel and aluminum, which is conveniently washed with distilled water and four alcohol traps of 96º and one end of absolute alcohol and preserved in absolute alcohol medium in refrigerator.
