Ngā mita mātotoru ā-rotoKa tukuna he mātauranga tukanga nui mō te purenga acetophenone i roto i ngā tono whakapiri kakara. Mā te ine i te mātotorutanga wā-tūturu ka taea te piri pono ki ngā paerewa parakore o te acetophenone, e tautoko ana i te kimi tonu i ngā poke benzene me te acetyl chloride i raro i te 0.5%. Ka arotauhia e ngā kaiwhakahaere ngā tikanga whakatōtika tika, ā, ka whakarerekē aunoa i ngā ōwehenga reflux hei pupuri i te 99.5% acetophenone. I te wā e whakaranu ana me te whakaranu i roto i te hanga kakara, ka whakaūhia e ngā mita mātotorutanga ā-roto te pumau o te mātotorutanga wāhanga waro ki te 1.045–1.050 g/cm³, ka ārai i te hanganga oxime hydrolysate mā te kimi wawe i te mutunga o te tauhohenga.
AcetophenoneTirohanga Whānui mō te Tukanga Whakaputa
Mā te waikura ethylbenzene ka puta he acetophenone, ka whakakorikoria e te cobalt, e te manganese acetates rānei i te 120–200°C mō ngā hua tae atu ki te 90%. Mā te wehenga maha-wāhanga ka whakakorea te phenylethane me ngā hydroperoxides, kātahi ka wehea te acetophenone e te whakakōkī wāhanga tika. Ka aroturukihia e ngā mita kiato ā-roto te parakore o te whakakōkī, ka taea ai te whakarerekē i te ōwehenga reflux wā-tūturu kia mau tonu te ≥99.5% acetophenone, he mea nui mō ngā tono whakapiri kakara. Ka āwhina te urupare kiato i te kimi i te poke o te benzene me te acetyl chloride—he mea nui te pupuri i ngā paepae i raro i te 0.5% mō te purenga acetophenone. Mā te whakahaere ā-roto aunoa ka whakarite kia puta ngā ōwehenga reflux whakakōkī i waenga i te 2:1 me te 3:1, ka whakapai ake i te tango poke me te whakaiti i ngā hapa ā-ringa.
I te wā o te whakaōritenga, ka whakaū te tangohanga dichloromethane i te mātotoru āhua waro i waenga i te 1.045–1.050 g/cm³, ka aro turukihia tika mā te whakamahi i ngā taputapu mātotoru ā-roto a Lonnmeter. Ka ārai tēnei matapihi mātotoru i te hanganga o te oxime hydrolysate, ā, ka whakahaere i te tāpiritanga o te konutai hauwai. Ko ngā hekenga mātotoru e tohu ana i te tangohanga kāore i oti, ka whakaoho i te arotautanga tika o te tere rere o te tangohanga mō te hanga acetophenone parakore teitei. Ka akiaki te ine ā-roto i te tika o te whakaranu me te whakaranu, ka tautoko i ngā paerewa parakore acetophenone me te hanga kakara pai.

Ngā Wero i roto i te Ine i te Kiato ā-Rāina
He nui ngā wero hangarau me ngā wero whakahaere e pā ana ki te ine i te mātotoru ā-roto mō te purenga acetophenone:
Me kimi ngā poke o te benzene me te acetyl chloride i raro i te 0.5% kia tutuki ai ngā paerewa parakore o te acetophenone mō ngā whakamahinga whakapiri kakara. Me aroturuki ngā rerekētanga matotoru iti iho i te 0.0005 g/cm³ kia taea ai ngā tikanga tango poke tere me ngā whakatikatika tonu.
Ka whakamahia e ngā tikanga whakatōtō tika te urupare mātotoru wā-tūturu hei pupuri i te ōwehenga reflux whakahaeretia (2:1–3:1). Mā te whakahaere mātotoru pakari ka ārai i te ngaronga o te hua i waho o te whakaritenga me te ngaronga o ngā rauemi mata. Ko ngā rerekētanga e tohu ana i te rerekētanga o te parakore o te acetophenone, te whakaranu me te whakaranu kāore i oti i roto i te hanga kakara.
Me whakatau tika te pito whakamutunga mō te tukanga tauhohenga whakahāngai. Me kite ngā taputapu ā-roto i te tere tipu mātotoru o te ≤0.001 g/cm³/h mō te whakahaere haumaru me te aunoa i te tāpiritanga kawakore, hei ārai i te nui rawa o te hauwai konutai i roto i te hanganga rauropi.
Ka puta te tangohanga dichloromethane kāore i oti hei hekenga mātotoru i roto i te wāhanga waro. Mā ngā mita mātotoru ā-roto o te lonnmeter ka taea te arotau i te tere rere o te tangohanga, kia mau ai te mātotoru wāhanga i te 1.045–1.050 g/cm³ i te wā e aroturukihia ana te hanganga acetophenone oxime.
Ko te ārai whai hua o te oxime hydrolysate e whakawhirinaki ana ki te kitenga i te mutunga o te tauhohenga i roto i ngā tukanga matū i te wā tūturu. Mā te ine ā-roto e tohu te wā me mutu te whāngai kawakore i mua i te hanganga o ngā hua taha.
Ngā Painga o te Whakauru i ngā Mita Matotoru ā-Rāina
Mā te whakahaere aunoa o te takirere hua e herea ana ki te ine i te mātotoru ā-roto ka whakarite kia puta noa te rere ki runga ake i te 1.027 g/cm³, ka whakaiti tere i te tukunga rauemi iti-motuhake. Mā te aroturuki tonu i te mātotoru ka taea te kite wawe i ngā poke benzene me te acetyl chloride i raro i te 0.5%, ka whakaoho wawe i te whakatikatika mahi. Ka arotauhia e te urupare wā-tūturu ngā ōwehenga reflux whakatō i waenga i te 2:1 me te 3:1, ka whakanui ake i te hua acetophenone ki runga ake i te 99.5% me te whakaiti i te para rauemi mata. Ka whakakorehia e te tātari ā-roto te tauira ā-ringa, ka tapahia ngā wā tatari tauira me te hapa tangata, ā, ka whakaitihia te wā kore utu mō te manatoko kounga neke atu i te 40%. Mā te raraunga ā-roto ōrite ka whakaū i te whakaranu me te whakaranu, ka pupuri i te parakore o te acetophenone mō ngā tono whakapiri hinu kakara puta noa i ngā wā roa. Ka tuhia ia uara mātotoru me te whakatikatika, ka whakarato i ngā tuhinga ka taea te arotake mō te tutuki i ngā paerewa parakore acetophenone. Ka tautokohia e ngā taputapu lonnmeter te whakaurunga maeneene ki ngā raina tukanga o nāianei, ka tukuna te mana tika i te wā whakatō, te tango, me te whakaōrite me te iti o te wawaotanga.
Whakatauhia ngā raruraru uaua i roto i te tukanga whakaputa
Tonoa he utu mō te mita mātotoru ā-roto Lonnmeter hei aro atu ki ngā tono purenga acetophenone me te whakapiri kakara. Whakamahia ngā taputapu Lonnmeter mō ngā painga ine mātotoru ā-roto, te arotau i te ōwehenga reflux whakahoro, me te pono o te tukanga tango dichloromethane. Tautokohia ngā tuhinga paerewa parakore acetophenone, te whakatikatika tukanga tonu, me te arotau i te tere rere o te tangohanga me ngā pūoko tukanga pakari, tika.
