Ao Whānui - Waikawa Adipic Matua: Te Poraka Hanga Matua mō ngā Pūmua me ngā Matū Mahi-Tiketike

Ngā Āhuatanga Ā-tinana me te Matū

Āhua me te Kakano: Ko te Waikawa Adipic he paura mā, he tioata rānei, he tioata iti, kāore he tae. He maeneene te kakano, ā, kāore he kakara i raro i ngā āhuatanga noa, nā reira he pai mō ngā whakamahinga maha e hiahiatia ana he āhua pūngao koretake.
Wairewatanga: He wairewatanga taurite tōna ki te wai, tata ki te 1.44 karamu ka rewa ki te 100 mL o te wai i te 25°C. Heoi, he tino wairewa ki ngā whakarewa waro pērā i te etanoru, te acetone, me te benzene. Mā tēnei whanonga wairewatanga ka taea e ia te whai wāhi pai ki te whānuitanga o ngā tauhohenga matū me ngā hanganga.

Ngā Pūmau Ā-tinana Matua: Ko te taumaha molar o te Waikawa Adipic he 146.14 g/mol. Ko tōna mātotoru he tata ki te 1.36 g/cm³ i te 25°C, he paku mātotoru ake i te wai. Ko te ira rewa o te waikawa adipic he 152°C, e tohu ana i tōna nekehanga mai i te āhua totoka ki te āhua wai i raro i ngā pāmahana teitei. Ka puta te ira kohua i te 337.5°C, ahakoa ka tīmata pea te pirau i mua i te taenga ki tēnei pāmahana i raro i te pēhanga hau. Ko tōna ira mura he 207°C, e kī ana me nui ake ngā pāmahana me ngā pūtake mura kia puta ai he mōrearea mura.

Te Tauhohenga Matū: Hei waikawa dicarboxylic, kei roto i te waikawa adipic ngā rōpū mahi carboxyl e rua (-COOH), e whakarato ana i te kaha o te tauhohenga matū. Ka uru wawe atu ki ngā tauhohenga esterification me ngā waipiro, ka hanga i ngā esters e whakamahia whānuitia ana i roto i te hanga kirihou, hinu whakahinuhinu, me ngā kakara. Hei tāpiri, ka taea e ia te tauhohe ki ngā diamines mā te polymerization condensation hei hanga polyamides, ko te nairona 6,6 te mea tino rongonui. Ko tēnei tauhohenga polymerization he tūāpapa o te muka hangai me te ahumahi kirihou hangarau. Ka taea hoki e te waikawa adipic te whai i ngā tauhohenga whakaiti hei hanga waipiro e rite ana, ā, ka taea hoki te tauhohe ki ngā turanga hei hanga tote, e mōhiotia ana ko ngā adipates.

Ngā Wāhi Whakamahinga

Te Hanganga Polyamide (Nailona): Ko te whakamahinga nui rawa atu me te mea nui rawa atu o te waikawa adipic kei roto i te hanga polyamides, inā koa ko te nairona 6,6. I roto i tēnei tukanga, ka tauhohe te waikawa adipic ki te hexamethylenediamine i roto i te tauhohenga polymerization condensation. Ko te nairona 6,6 ka puta he kirihou hangarau mahi-teitei e mōhiotia ana mō tōna kaha, tōna roa, tōna ātete ki te pakū, me ōna āhuatanga miihini pai rawa atu. E whakamahia whānuitia ana te nairona 6,6 i roto i te umanga motuka mō ngā wāhanga pēnei i ngā wāhanga miihini, ngā taputapu, me ngā peera. He rauemi matua anō hoki i roto i te umanga kakahu, e whakamahia ana hei hanga papanga kounga teitei mō ngā kākahu, ngā whāriki, me ngā whakapaipai nā tōna kaha, tōna manawanui, me tōna kaha ki te pupuri pai i ngā tae.

Ngā Kaiwhakaahua me ngā Kaiwhakahinuhinu: Ka whakamahia te waikawa adipic hei hanga i ngā mea hanga kirihou e ahu mai ana i te adipate. Ka tāpirihia ēnei mea hanga kirihou ki ngā pūmua, inā koa te polyvinyl chloride (PVC), hei whakapai ake i tōna ngāwari, te ngāwari ki te tukatuka, me te roa. He pai ake ngā mea hanga kirihou adipate i roto i ngā tono e hiahiatia ana te ngāwari ki te pāmahana iti, pērā i te hanga i te whakamahana waea motuka, ngā ngongo hauora, me ngā hua PVC ātete-makariri. Hei tāpiri, ka whakamahia ngā esters i ahu mai i te waikawa adipic hei hinu whakahinuhinu i roto i ngā tono ahumahi maha, e whakarato ana i ngā āhuatanga ārai-kakahu me te ārai-waku tino pai, ā, he pai mō te whakamahi i roto i ngā miihini, ngā taputapu, me ētahi atu pūnaha miihini.

Ahumahi Kai me te Inu (Whakamahinga Ā-kore): Ahakoa kāore te waikawa adipic e kainga tika ana i roto i te kai, ka whakamahia i roto i te hanga rauemi pa ki te kai me ngā taputapu tukatuka kai. Ina whakamahia ana ōna esters ki roto i ngā paninga me ngā hiri mō ngā rauemi takai kai, ka āwhina i te whakarite i te pono me te haumaru o ngā hua kai mā te ārai i te poke me te pupuri i te hou o te hua. Hei tāpiri, ka taea te whakamahi i ngā polymers e hangai ana ki te waikawa adipic i roto i te hanga wāhanga taputapu e pa ana ki te kai i te wā tukatuka, pērā i ngā whitiki kawe me ngā hiri.

Ngā Ahumahi Rongoā me te Whakapaipai: I roto i te umanga rongoā, ka taea te whakamahi i te waikawa adipic hei tāpiri i roto i ngā hanganga rongoā. Ka taea e ia te mahi hei kaihoko ārai hei whakahaere i te pH o ngā otinga rongoā me ngā whakatārewatanga, kia mau ai te pumau me te whai huatanga o ngā rongoā. I roto i te umanga whakapaipai, ka whakamahia ngā esters waikawa adipic i roto i ngā momo hua, pērā i ngā kirīmi, ngā hinu kiri, me ngā rīpene ngutu, hei whakapai ake i te kakano, hei whakarei ake i te horapa, me te whakarato i ngā āhuatanga whakangawari, kia ngawari ai te kiri, kia māeneene ai.

Ngā Tikanga Whakarite

Te whakahāoratanga o te Cyclohexane: Koinei te tikanga ahumahi matua mō te whakaputa waikawa adipic. Ka tīmata te tukanga mā te whakakōkī o te cyclohexane i te aroaro o tētahi whakakōkī, ko te tikanga he whakakōkī kei roto i te cobalt. I te whakakōkī tuatahi, ka tauhohe te cyclohexane ki te hau, ki te hāora rānei hei hanga i tētahi ranunga o te cyclohexanol me te cyclohexanone, he tukanga e mōhiotia ana ko te tukanga "hinu KA" (ketone - hinu waipiro). Ka mahia te tauhohenga i te pāmahana tata ki te 150 - 160°C me te pēhanga o te 1 - 1.5 MPa. Muri iho, ka whakakōkīhia anō te hinu KA i roto i tētahi tauhohenga tuarua mā te whakamahi i te waikawa hauota hei kaiwhakakōkī, i te nuinga o te wā i te pāmahana o te 60 - 80°C me te pēhanga hau. Ka hurihia e tēnei whakakōkī tuarua te cyclohexanol me te cyclohexanone hei waikawa adipic. Heoi, he wero taiao kei tēnei tikanga, nā te mea ko te whakamahinga o te waikawa hauota ka whakaputa i te hauota hauota (N₂O), he hau kati kōtuhi kaha, ā, me whakahaere tupato ngā awa para.

Ngā Huarahi Hangarau Koiora: I ngā tau tata nei, kua piki haere te hiahia ki ngā tikanga hangarau koiora hei whakaputa waikawa adipic hei huarahi tauwhiro ake. Ka taea te whakamahi i ngā rauropi iti, pērā i ngā huakita i hangaia ira, i te rewena rānei, hei huri i ngā rauemi whakahou, pērā i te huka, i ngā hinu tipu rānei, hei waikawa adipic mā roto i te raupapa o ngā ara pākia. Hei tauira, ka taea te hanga i ētahi huakita hei whakaputa i ngā takawaenga ka taea te huri anō hei waikawa adipic. Ahakoa kei te wāhanga whanaketanga tonu ēnei tikanga hangarau koiora, ā, e pā ana ki te hua me te whai huatanga o te utu, ka tukuna e rātou te kaha mō te whakaputa waikawa adipic e pai ake ana ki te taiao me te tauwhiro ake i te heke mai.

Ngā Whakatūpato

Ngā Tūponotanga Hauora: Ka taea e te waikawa adipic te whakararuraru i te kiri me ngā kanohi ina pā tika atu. Mēnā ka roa te pānga ki te kiri, ka puta pea he mate kiri kiri, ā, ki te pā atu ki ngā kanohi, ka whero, ka mamae, ka kino pea te kornea. Mā te hongi i ngā matūriki puehu o te waikawa adipic ka whakararuraru i te ara manawa, ka puta te maremare, te wheezing, me te poto o te manawa. Mā te horomitanga o te nui o te waikawa adipic ka puta he mamae o te puku, tae atu ki te whakapairuaki, te ruaki, me te korere. Me mau ngā kaimahi e whakahaere ana i te waikawa adipic i ngā taputapu tiaki whaiaro e tika ana, pērā i ngā karapu, ngā mōhiti haumaru, me ngā kopare manawa, inā koa i ngā taiao ka taea te whakaputa puehu.

Ngā Mōrearea Ahi me te Pahūtanga: Ahakoa he teitei te pāmahana mura o te waikawa adipic, he mura tonu. I te āhua paura, ka taea e ia te hanga ranunga pahū me te hau mēnā ka horahia ki ngā kukū e tika ana. Me waiho ngā wāhi rokiroki kia matara atu i ngā pūtake mura, ā, he mea nui te hauhautanga tika hei ārai i te kohikohinga o te puehu. Mēnā he ahi kei roto i te waikawa adipic, me whakamahi ngā kai tinei ahi e tika ana, pērā i te paura matū maroke, te hauhā waro rānei.

Pānga ki te Taiao: He āhua pumau te waikawa adipic i roto i te taiao. Ina tukuna ki roto i ngā wai, ka taea te whakapōrearea e ngā moroiti i roto i te wā, engari ka pā tonu te nui o ngā kukū ki ngā mea ora i roto i te wai. Tērā pea ka pā ki te pH o ngā pūnaha wai nā tōna āhua waikawa. Nō reira, he mea nui te whakahaere tika i ngā para me ngā mahi aukati hei ārai i te tukunga kore whakahaere o te waikawa adipic ki te taiao. Me piri ngā ahumahi e whakaputa ana, e whakamahi ana rānei i te waikawa adipic ki ngā ture taiao tino pakari hei whakaiti i tōna pānga ki te oneone, te wai, me te kounga o te hau.
