Kare e rewa i roto i te wai me te etera, ka whakarewahia ki te waipiro me te nuinga o nga whakarewa pararopi. Ka pa ana ki te marama, ki te hau ranei, ka tere te parauri me te kakara aniline.

Whakamahinga:

Ka whakamahia tenei hua ki te whakahiato waro, he takawaenga nui mo nga waikano azo me nga tae triphenylmethane; ka taea hoki te whakamahi hei takawaenga mo nga matū pai penei i te taapiri rapa, te pahū, me nga taonga whakaahua.

Tikanga whakaputa

1. Tikanga waikawa pūhaumāota: tauhohe i te aniline hydrochloride me te waihā i te 180°C me te 2.94MPa, whakamaua atu i te taikaha o te waihā me te eter hua-hua, ka tāpirihia te 30% NaOH me te p-toluenesulfonyl chloride, ka tango i nga hua-a-maama ma te whakamaroke mamaoa diethylaniline , ka taapirihia te waikawa pungatara kia whiwhi ai i te hua. 2. Tikanga Phosphorus trichloride: tauhohe i te aniline, te waiwaro me te phosphorus trichloride i te 300°C me te 9.84MPa, me te hautau i te ranunga tauhohenga ma te whakamaroke korehau kia whiwhi N-ethylaniline.
