Ngā tikanga hangai

1. Mā te aniline me te methanol i te aroaro o te waikawa whanariki, ka tauhohe mā te pāmahana teitei me te pēhanga teitei. Te rere o te tukanga: 1. Tāpirihia he 790kg o te aniline, 625kg o te methanol me te 85kg o te waikawa whanariki (100% o te ammonium) ki te tauhohenga, whakahaeretia te pāmahana 210-215℃ me te pēhanga 3.1MPa, tauhohe mō te 4h, kātahi ka tukuna te pēhanga, tukuna te rauemi ki te wehewehe, whakakorea ki te 30% konutai hauwai, waiho, ka wehea te tote ammonium quaternary o raro. Kātahi ka tauhohenga waikura i te 160℃, 0.7-0.9MPa mō te 3h, ka whakakotahihia te waikura hua me te hinu o runga ki te horoi wai me te whakakore korehau kia puta ai te hua oti.

2, me te methanol me te aniline hei rauemi mata, i raro i te āhua o te methanol nui rawa, te pēhanga hau, 200-250℃, mā te hanga whakakorikori alumina. Te rahinga kai rauemi mata: aniline 790kg/t, methanol 625kg/t, waikawa whanariki 85kg/t. Ka taea e te whakaritenga taiwhanga te tauhohe i te aniline me te trimethyl phosphate.

3. I konatunatua te aniline me te methanol (N aniline: N methanol ≈ 1:3) ka werohia ki roto i te tauhohenga kua whakauruhia ki te whakakorikori i te tere wāhi o te 0.5h-1 mā te papu ine kore-pāoro. Ka uru tuatahi te para tauhohenga ki te wehewehe hau-wai karāhe, ā, ka tangohia te wai i kohia i te wāhanga o raro o te wehewehe i ia wā mō te tātari chromatography.

4. I te tau 2001, i whakawhanakehia ngātahitia e te Whare Wānanga o Nankai me Tianjin Ruikai Science and Technology Development Co., Ltd tētahi whakakorikori methylation aniline tino whai hua hei whakatutuki i te hanganga hau o te N, N-dimethylaniline.

Ko te hua o te DMA kei runga ake i te 96%.

Tikanga whakamahine: he maha ngā wā kei roto ko te aniline, te N-methyl aniline me ētahi atu poke. I te wā e whakamahine ana, ka whakarewaina te N, te N-dimethylaniline ki te 40% waikawa whanariki, ā, ka mahia te whakamaroke mamaoa. Ka tāpirihia te hauwai konutai kia hanga hei matū. Ka haere tonu te whakamaroke mamaoa. Ka wehea te whakamaroke ki tētahi paparanga wai, ā, ka whakamarokehia ki te hauwai pāhare pākawa. Te whakamaroke i te pēhanga hauātea i te aroaro o te anhydride acetic. I horoia te whakamaroke ki te wai hei tango i ngā iti o te anhydride acetic, kātahi ka whakamarokehia ki te hauwai pāhare pākawa, ā, muri iho ko te hauota barium me te whakamaroke i roto i te awa hauota. Ko ētahi atu tikanga whakamahine ko te tāpiri i te 10% anhydride acetic me te reflux mō ētahi haora hei tango i ngā amine tuatahi me ngā amine tuarua. I muri i te whakamatao, tāpirihia te 20% waikawa hauwai pāhare pākawa me te tango me te ether. I hangaia te paparanga waikawa hauwai pāhare pākawa mā te tāpiri i te kawakore, kātahi ka tangohia me te ether. I whakamarokehia te paparanga ether ki te hauwai pāhare pākawa, kātahi ka whakamarokehia i raro i te pēhanga i raro i te hauota. Ka taea hoki te huri i te N, N-dimethylaniline ki te picronate, ka whakakākanohia anō kia pumau te pūwāhi rewa me te wai mahana 10% konutai hauwai hei wawahi i te picronate. Tangohia ki te ether, horoia ki te wai, ka whakamaroke i muri i te whakatōtō korehau.

5. Ka whakaranua te aniline, te methanol me te waikawa whanariki kia rite te ōwehenga, ā, ka whakakōpiritia ki roto i te autoclave. I muri i te whakahokinga mai o te hua tauhohenga mā te whakaiti i te pēhanga, ka tāpirihia te kawakore hei whakakore, hei wehewehe, kātahi ka whiwhihia te hua mā te whakakore korehau.

6. Ka taea e te tauhohenga methylation o te aniline me te trimethyl phosphate te whakaputa i te N, N-dimethylaniline: kātahi ka tangohia ki te ether, te whakamaroke maroke.

7. Ka taea te hanga i te N, N-dimethylaniline mā te tāpiri i te ranunga o te aniline me te methanol i te ōwehenga o te 1:3.5 i roto i te moenga whakakorikori o te Cu-Mn, Cu-Zn-Cr Ziegler rānei i te 280℃. Ko te hua o te N, N-dimethylaniline ka kohia i roto i te waeine whakakorikori o ngā pereti 54 i te awhe o te 193 ki te 195℃ ka tākai ki roto i ngā pounamu karāhe parauri. Mō te whakarite i te chromatography, ka taea te whakamahi i te hau kawe N, N-dimethylaniline, te hauota parakore, i roto i te whakarite i te chromatography hau me te pou Ben 犅 yaku ka werohia te whakatikatika o te N, N-dimethylaniline, mā te wehenga me te kohikohi i te wāhanga matua o te tihi, kātahi ka taea te hiri ki roto i te ampoule karāhe.
