Abstract
N,N'-Di-sec-butyl-p-phenylenedialnine was synthesized with p-phenylenediamine as raw material,diisobutyl bromide as alkylation reagent,ethanol as solvent,sodium hydroxide as acid astringent by single molecule nucleophilic substitutions.The effects of synthesis conditions such as the amount of ethanol,the mole ratio of diisobutyl bromide to p-phenylenediamine,reaction temperature,reaction time and etc on yield of the product were studied.The experimental results showed that a 94%~95% product recovery was obtained when the mole ratio of diisobutyl bromide to p-phenylene-diamine was 2.05,the weight ratio of p-phenylenediamine to ethanol was 4,and the reaction was carried out at 75 °C for 8 h.The product was identified by IR spectroscopy.
