Acetonitrile (CAS 75-05-8) – He Whakarewa Parakore Teitei mō ngā Whakamahinga Rongoā me ngā Matū
Ngā Āpure Tono Matua
I roto i te tātari matū, ko te acetonitrile te whakarewa e whakamahia whānuitia ana mō te tātari chromatography wai mahi-teitei (HPLC) me te tātari chromatography hau (GC). He pai te wairewatanga, he iti te matotoru, ā, he pai te whakarewa i ngā momo matū waro me ngā matū kore-waro hei whakarato i ngā hua tātari mārama. Ka whakamahia hoki te acetonitrile hei whakarite i ngā otinga paerewa me ngā wai whakataurite, hei whakarite i te tika me te pono o te tātari.
I roto i te hanganga rauropi, he mea nui te acetonitrile hei whakarewa me te takawaenga. Ka taea e ia te whakarewa i ngā momo matū rauropi, ka whakarato i tētahi taiao pumau mō ngā tauhohenga matū. Hei tauira, i roto i te hanganga o ētahi takawaenga rongoā me ngā matū kakara, ka taea e te acetonitrile te mahi hei whakarewa hei whakatairanga i te tauhohenga. Hei tāpiri, ka taea e te acetonitrile te whai wāhi ki ētahi tauhohenga matū hei whakaputa i ngā matū me ngā mahi motuhake. Hei tauira, ka taea e te acetonitrile te whai i ngā tauhohenga whakakapinga nucleophilic me tana rōpū cyano hei whakaputa i ngā matū amine, waipiro rānei e rite ana.
I roto i te umanga rongoā, he whānuitia te whakamahinga o te acetonitrile i roto i ngā tukanga hanga me te purenga rongoā. Ka taea e ia te whakarewa i ngā momo matū me ngā takawaenga rongoā, hei whakahaere i ngā tauhohenga matū whai hua. Hei tauira, i roto i te hanga o ētahi paturopi me ngā rongoā ngakau, ka taea e te acetonitrile te mahi hei whakarewa hei whakanui ake i ngā tere tauhohenga me ngā hua. Hei tāpiri, ka taea te whakamahi i te acetonitrile mō te whakatiotanga me te purenga rongoā hei whakarite i te parakore me te kounga o te rongoā.
I roto i te umanga kakara me te whakapaipai, ka whakamahia te acetonitrile hei hanga me te pure i ngā matū kakara. Ka taea te whakamahi hei tango i ngā wāhanga kakara taiao, pērā i ngā hinu kakara mai i ngā tipu. Hei tāpiri, ka taea te whakamahi i te acetonitrile hei hanga i ngā matū kakara me ngā kakara ahurei mō ngā hinu kakara me ngā whakapaipai.
I roto i te umanga hikohiko, ka whakamahia te acetonitrile hei horoi me te whakarewa. Ka taea e ia te tango pai i ngā toenga me ngā poke mai i te mata o ngā wāhanga hiko, kia ma ai, kia pai ai te mahi a ngā wāhanga hiko. Hei tauira, i roto i te hanga semiconductor, ka taea te whakamahi i te acetonitrile hei horoi i te mata o ngā wafers, hei tango i ngā toenga photoresist me ētahi atu poke.
Ahakoa te whānuitanga o ngā whakamahinga, he pūngāwerewere, he paitini hoki te acetonitrile, ā, me tino tupato te whakamahinga me te rokiroki. Ka mimiti ngāwari te acetonitrile i te hau, nō reira me whakamahi i roto i te taiao e pai ana te hau. Hei tāpiri, he paitini te āhua o ngā otinga o te acetonitrile, ā, me mau ngā taputapu tiaki tika i te wā e whakamahia ana kia kore ai e pā ki te kiri me ngā kanohi. I roto i te whakaputanga ahumahi, ko te whakamahinga o te acetonitrile ka puta i roto i ngā pūnaha kati hei whakaiti i te pānga ki te taiao.

Hei whakarāpopototanga
Hei whakarāpopototanga, ko te acetonitrile, hei rauemi mata matū waro me te whakarewa nui, he mahi nui tana i roto i ngā ahumahi maha. Ehara i te mea ka whakarei ake i te whai huatanga me te hua o ngā tauhohenga matū anake, engari ka tautoko hoki i te whanaketanga o te ahumahi hou. Mā te haere tonu o ngā whanaketanga hangarau, ka whānui ake ngā tūmanakohanga tono mō te acetonitrile.
