반응 단계
60 g of 2-nitro-5-chloro-2'-hydroxy-3'-tert-butyl-5'-methylazobenzene (purity 86%), 40 g of xylene, 60 g of n-butylamine and 1 g of 1% Pt on activated carbon are put into a 300 ml hydrogenation reactor at room temperature under argon. Argon is then replaced by hydrogen. After the injection of 10 bar hydrogen, the hydrogenation is carried out at 35°-37° C. with intensive stirring. The heat released is removed by cooling. The end of the hydrogenation reaction is easily detectable by the hydrogen absorption ceasing after 2 mol equivalents of hydrogen, relative to the azobenzene starting product. The total hydrogenation time is about 1.5 hours.
