Reaction Steps

131 parts of tetrachloroaniline/pentachloroaniline mixture corresponding to the data in Example 3, 200 parts of phenol, 5.7 parts of iodine and 33 parts of a 5% strength ruthenium-on-charcoal catalyst which is moist with water (23 parts dry) are brought to reaction in a tantalum autoclave, whilst stirring, during the course of 4 hours, at 165° C. and under a maximum hydrogen pressure of 50 bars. After the usual working up, 87 parts of 98% strength 3,5-dichloroaniline are obtained (93% yield).
