Tikanga whakaputa

1. Tikanga waikawa hauwaiora: tauhohe i te aniline hydrochloride me te etanoru i te 180°C me te 2.94MPa, ringihia te etanoru taikaha me te etera hua taha, kātahi ka tāpirihia te 30% NaOH me te p-toluenesulfonyl chloride, ka tangohia ngā hua taha mā te whakamaroke mamaoa diethylaniline, kātahi ka tāpirihia te waikawa whanariki hei whiwhi i te hua. 2. Tikanga phosphorus trichloride: tauhohe i te aniline, te etanoru me te phosphorus trichloride i te 300°C me te 9.84MPa, ka wehewehea te ranunga tauhohe mā te whakamaroke korehau hei whiwhi i te N-ethylaniline.
