N-Propanol: He Rauemi Matū Waro Hira
Ngā Āpure Tono Matua
I roto i te umanga matū, he mea nui te n-propanol hei takawaenga i roto i te hanga rauropi. Ka taea te whakamahi hei whakaputa i ngā momo matū, pērā i te waikawa kiriaku, ngā matū akirirata, te propyl acetate, te propyl urea, me te bromopropane. He whānuitia te whakamahinga o ēnei matū i roto i te hanga kirihou, paninga, piripiri, kakara, me ngā tāpiringa kai. Hei tauira, ko te waikawa kiriaku me ōna esters he rauemi mata matua mō te hanga paninga me ngā piripiri mahi-teitei; he mea noa te whakamahi i te propyl acetate i roto i ngā umanga hanga rauropi me te whakarewa hei whakarewa ira-kohua teitei. Hei tāpiri, ka taea te whakamaroke i te n-propanol hei whakaputa propylene, he rauemi mata nui mō te hanga kirihou polypropylene.
I roto i te umanga rongoā, ka whakamahia te n-propanol hei whakaputa i ngā momo takawaenga rongoā. Hei tauira, ko te probenecid, e whakamahia ana hei rongoā i te kauti, he takawaenga nui te n-propanol i roto i tana hanganga; ko te valproate sodium, he rongoā ārai mate haurangi, e whakawhirinaki ana ki te n-propanol i roto i tana tukanga whakaputa. Hei tāpiri, ka whakamahia te n-propanol hei whakarewa mō ngā rongoā, inā koa i roto i te hanga werohanga me ngā wai ā-waha. Ka taea e ia te whakarewa i ngā wāhanga rongoā maha kāore e tino wairewa, ka whakarei ake i te pumau me te waatea o te koiora o ngā rongoā.
I roto i ngā whakapaipai me ngā hua tiaki whaiaro, he mea whakamahi noa te n-propanol hei whakarewa. Ka taea e ia te whakarewa i ngā momo kai hohe, ngā kakara, me ngā tae, ka āwhina i ēnei wāhanga kia pai ake te horapa ki roto i ngā hua. Hei tauira, i roto i te hanga hinu kakara, ka taea te whakamahi i te n-propanol hei whakarewa hei tohatoha ōrite i ngā wāhanga kakara, hei whakarei ake i te roa me te pumau o te hinu kakara. Hei tāpiri, ka taea te whakamahi i te n-propanol hei patu huakita mō te horoi me te patu huakita i roto i ngā hōhipera, ngā taiwhanga, me ngā whare. He pai ōna pānga patu huakita, ka taea te patu huakita me ngā huaketo, ā, he ngawari te piki me te heke, kāore he toenga e toe ana i muri i te whakamahinga.
I roto i te kaihoroi me ngā mara wahie, ka whakamahia te n-propanol hei whakaputa wai parai. He pai te wairewa me te hinu whakahinuhinu, ka whakaiti i te waku i roto i ngā pūnaha parai me te whakapai ake i te mahi parai. Hei tāpiri, ka taea te whakamahi i te n-propanol hei tāpiri wahie i roto i ngā wahie whakaranu hei whakapai ake i te pai o te mura. Hei tauira, mā te tāpiri i te iti o te n-propanol ki te penehīni ka taea te whakapai ake i ōna āhuatanga ārai-patuki me te mahi mura me te whakaiti i ngā tukunga hau.
Nā ngā āhuatanga matū o te n-propanol, he maha ngā whakamahinga o tēnei hua. He pai te wairewatanga, ā, ka taea te whakaranu ki te wai, ki ngā waipiro, ki ngā etera, me ētahi atu whakarewa. He iti noa te paitini o te n-propanol, he 97.2°C te pāmahana kohua, ā, he -127°C te pāmahana rewa, engari ka taea te whakararuraru i ngā kanohi, i te ara manawa, me te kiri i ngā kukū tiketike. Nō reira, i te wā e whakamahia ana, e rongoatia ana, me mau ngā taputapu tiaki tika hei karo i te pa atu ki te kiri me ngā kanohi, ā, me pupuri tonu te hauhautanga pai.
