Mā ngā tikanga ine i te mātotoru wai ā-roto whai hua ka whakaitihia ngā utu rauemi mata, ka tautoko i te whakaotinga rakau wai-rite, ā, ka whakahaeretia te tukanga whakaputa paninga whānui. Ka whakaitihia e te aroturukitanga wā-tūturu te rerekētanga o te tukanga, ka whakaitihia te para rauemi mata, ā, ka whakanuia te pono o te mahi. Mā te putanga pumau, teitei-parakore ka whakarite i te kounga pumau mō ngā tono o muri mai i roto i ngā paninga matatau me ētahi atu rāngai matū.
Te Wāhi Hanga Ethyl Acetate

Kupu Whakataki
Ka pā tika te tika o te ine i te mātotoru wai i te wā tūturu ki te whai huatanga o te whakaputanga ethyl acetate me te ahumahipaningakounga. Ka whakaitihia e ngā mita mātotoru ā-roto, pērā i ngā pūoko ngongo wiri me ngā pūoko haruru cantilever, ngā hapa whakatakotoranga, ka whakatika i ngā nekehanga mātotoru i roto i ngā hēkona. E whakaatu ana ngā rangahau ka whakahaerehia e ēnei pūoko te hua tukanga ethyl acetate neke atu i te 95% mā te whakamahi i te esterification Fischer, ka whakaitihia te waikawa acetic me te etanoru kua moumouhia. Ka pupurihia e ngā ine ā-roto aunoa te mātotoru pumau i te wā o ngā whakawhiti rere tukanga—te tauhohenga, te whakahoro, me te whakaranu—ka whakapai ake i te mahi taiao o ngā paninga rakau wai. Ka āraihia e te aroturuki wā-tūturu te rerekētanga e arahi ana ki te pakaru kiriata me te totohu peita. Mā te whakauru i ngā mita kukū ā-roto ki te hanga paninga ka taea te whakatikatika tere i ngā ōwehenga kai mō te horapa ōrite me te emulsification. Ka inehia e ngā taputapu ā-roto a Lonnmeter te mātotoru, te matotoru, me te pāmahana mō te hanga paninga matatau, pumau mā te whakamahi i te ethyl acetate, ka whakakore i te koretake o te puranga me te arotau i ia taahiraa hanga.
He Tirohanga Whānui mō te Tukanga Whakaputa Ethyl Acetate
Ka whakamahia te tukanga whakaputa ethyl acetate mā te whakamahi i te Fischer esterification, kia eke ai ngā hua ki runga ake i te 95% me ngā tawhā whakahaere. E toru ngā wāhanga matua o te tūtohi rere tukanga ethyl acetate: te tauhohenga, te whakahoro, me te purenga. I te wā o te tauhohenga, ka tauhohe te etanoru ki te waikawa acetic, mā te whakamahi i te waikawa whanariki hei whakakorikori i raro i te whakahaere tonu i te pāmahana me te pēhanga.
Ka whakauruhia te ine i te mātotoru ā-roto ki ngā wāhi tino nui, tae atu ki te ipu tauhohenga, ngā wae wehewehe, me ngā tāke whakaranu. Mā ngā taputapu mita roa ka taea te aroturuki i te mātotoru i te wā tūturu, te arotau i te wehenga ā-wāhanga me ngā wāhi tapahi whakatō. Ka ārai te aroturuki i te mātotoru wai ā-roto i ēnei wāhanga i ngā hua kāore i te tino tika, ā, ka tautoko i te tango wai i te wā purenga.
He mea nui te whakahaere tika i te mātotorutanga mō ngā hanganga paninga rakau wai i muri mai.Te ōritetanga i roto i te waiMā ngā āhuatanga ka pumau te matotoru, ka whakaitihia ngā take o te pakaru o te kiriata me te heke o te peita i roto i ngā paninga rakau e pai ana ki te taiao. Ka whakaratohia e ngā mita mātotoru ā-roto whakauru he urupare tonu, e whakatairanga ana i te ōritetanga me te mahi pono i roto i ngā mahi hanga paninga ahumahi.
Te whakaputanga o te etilasetāte mā te tikanga matū me te tikanga koiora

Te Hanga Paninga Ahumahi me ngā Paninga Rakau Wai
Ko ngā paninga rakau wai e whakawhirinaki ana ki te ethyl acetate hei whakarewa matua mō te hanganga tere o te kiriata me te ōritetanga o te mata. Me whakaputa e te tukanga whakaputa ethyl acetate he putanga parakore teitei kia tutuki ai ngā paerewa paninga e hiahiatia ana. Ko ngā mahi whakaranu, whakamarara, me te whakaemulsification me whakahaere ngā kukū whakarewa hei ārai i te wehenga ā-wāhanga me ngā āhuatanga kiriata koretake.
Ko ngā mahi hanga paninga ahumahi—te whakaranu kai, te whakakotahitanga, te tātari, me te tākai—e hiahia ana kia aroturukihia ngā kukū whakarewa i te wā tūturu. Ko te marara e whakahaeretia ana e te matotoru ka whakaiti i te hekenga o te peita, ka whakatika i ngā rerekētanga rere e puta mai ana i ngā matotoru rerekē. Ko ngā tikanga ine matotoru wai ka whakapai ake i te ōritetanga o te tukanga, ā, ka whakarite kia rite te kanapa, te pakari, me te tere maroke o ngā paninga rakau e pai ana ki te taiao. Mā te aukati i te paparanga me te whakakotahitanga ka whakarite kia rite te mutunga rakau e mau ana i te wai mō te whakamahinga ahumahi tino pai.
Ngā Wero Ine i te Kiato Wā-Tūturu
Ka pā tika te rerekētanga o ngā rauemi whāngai i roto i te tukanga whakaputa ethyl acetate ki te tere o te esterification. Ka nekehia ngā tere tauhohenga e ngā poke, te nui o te wai, me ngā ōwehenga tauhohenga e rerekē haere ana, ka puta he kukū hua koretake. Ka neke pea te pāmahana o te tukanga mā te ±5°C, ā, ka whakararuraru ngā huringa pēhanga neke atu i te ±0.1 pae i ngā tikanga ine kiato wai tika, me te hiahia kia tika ngā pānui mā te tuku pāmahana ā-roto me ngā tāurunga tuku pēhanga ā-roto.
Ka uaua te tika o te pūoko i ngā totoka whakatārewatia me ngā panonitanga o te matotoru. Ka pāngia pea ngā mita kiato ā-roto me ngā mita matotoru ā-roto mai i te mita Lonn mēnā ka piki ake te kawenga matūriki ki runga ake i te 50 μm, ka neke ake rānei te matotoru i te 2000 cP, ka whakapēkē i ngā pānui. Ko ngā rerekētanga puranga-ki-puranga—he mea noa i roto i ngā mahi hanga paninga ahumahi—ka piki ake te koretake o te whakahaere i ngā āhuatanga o te hua mutunga, inā koa ka huri ngā pūtake rauemi mata ia wiki.
Ko te taunga o ngā matūriki me te wehewehenga o te rere, e kitea whānuitia ana i te wā e whakaranua ana ngā paninga rakau wai, ka hua ake he tohu mātotoru kore pono i roto i ngā rere maha-wāhanga. Tērā pea ka puta he pikinga mātotoru o te 0.02 g/cm³ i roto i ngā paipa, i ngā tāke rānei, ka puta he rerekētanga i roto i te whakaotinga rakau wai. E whakanui ana ēnei wero i te hiahia ki te ine i te mātotoru o te wai i raro i ngā tikanga e tino whakahaeretia ana mō ngā paninga rakau e pai ana ki te taiao.
Ngā Painga o te Whakauru i ngā Mita Matotoru ā-Rāina/Mita Kukū
Mā ngā mita mātotoru ā-roto me ngā mita kukū, pērā i ngā mea mai i Lonnmeter, ka whakanuia te whakahaere tukanga i roto i te tukanga whakaputa ethyl acetate. Ka tukuna e rātou te kitenga wawe i ngā otinga kore-motuhake, ka taea ai te whakarerekē tere i te taahiraa whakahāngaitanga Fischer, i te wā whakaranu rānei. Ka whakaitihia e ngā raraunga wā-tūturu ngā pekapeka tukanga, ka whakanuia te ōritetanga hua ki runga ake i te 95%.
Mā ngā tikanga ine tonu i te mātotorutanga wai ā-roto ka āwhina i te pupuri i te parakore o te hua i te wā e whakatōngia ana, e purea ana hoki. Mā tēnei ka whakaitihia te utu nui o te mahi anō me te para o ngā rauemi mata, he mea nui mō te hanga pai o te ethyl acetate.
I roto i te tukanga whakaputa paninga mō ngā paninga rakau wai, mā te whakahaere i te matotoru o roto ka whakarite kia rite te hanganga kiriata o ia puranga. Mā te matotoru pumau ka tino whakaiti i ngā take pakaru kiriata me ngā mahi ārai i te mea ka aukati i te kore taurite o te whakarewa. Ka whakaiti tika hoki i ngā take me ngā whakatikatika o te peita e totohu ana, kia rite ai te tono me te maroke.
Tonoa he utu whakarite mō te mita mātotoru ā-roto. Whakatikahia ngā wero nui o te tukanga whakaputa ethyl acetate mā te whakamahi i ngā tikanga ine mātotoru wai tika. Whakapai ake i ngā mahi hanga paninga ahumahi, mai i te tūtohi rere o te tukanga ethyl acetate ki te tono paninga rakau wai. Whakatauhia ngā take pakaru kiriata me ngā take ārai, whakaitihia ngā take me ngā whakatikatika o te peita e totohu ana, me te arotau i tō tukanga paninga rakau hoa-taiao mā te ine tika i te mātotoru o te wai. Whakapūmau i te hanganga ōrite, whakaitihia te para, me te whakapai ake i te kounga o te whakaotinga rakau wai.
