Ko te hanga o te acetylene

Tino mohio rawa maha iwi e te kupu - acetylene - e hono ki te ariā o "winika". Ko te meka e acetylene tenei ra - ko reira anake te taonga e taea tahu ka te rangi kahore he whai wāhi, me e te whakamahia whānuitia i roto i te ahumahi, e kore e mohio katoa. Ko hoki Acetylene taumahatanga kino he meka taua e, mo te tauira, tona tahunga hua pāmahana waikawa mura ki 3100 ° C.

Hoki te wā tuatahi kawea hanga o acetylene i roto i Edmundom Devi i tawhiti i te 1836. mahi Devi i pāhare pāporo carbide tikanga puta wairewa te whārite tauhohenga e taea te tuhituhi rite: k2c2 = C2H2 + 2H2O + 2KOH. Ka rite ki te hua, he hau, ko tona tātai ko C2H2 me te wahi i hoatu e pūtaiao hauwai dvuuglerodisty taitara.

Ki te kitea o te mau haapiiraa o te Radicals Hutuha Liebig tetahi o nga rōpū o ngota (Radicals) ka ko acetyl, Heoi, kua whakaaro reira he pūhui o tātai S2N3. Ko te taonga, ko te taua, i ko Devi, i whai whakaaro mai Utaina rite te pärönaki o acetyl i. Na, ka kawea te hanga o te acetylene i roto e Wīwī Marselenom Berthelot i maha ngā huarahi, ka te taonga tona ingoa, whakamahia nei i roto i te matū ki tenei ra. whakaaro Berthelot rite te muingota hua acetyl pūhui, i tangohia nei i te ngota hauwai. Hangarau, te faaineineraa o acetylene Berthelot tohu te tukanga i muri. ngaro te reira i rua o waiwaihā wera - mewaro me te Ethyl - hoki i roto i te putorino wera ki te pāmahana teitei.

Ahua muri, i roto i 1862, i synthesized acetylene e te tauhohenga iahiko, i roto i nei haere hauwai i waenganui o nga electrodes i hanga o te waro. E i te wa enei hangarau i tino utu me te hauarea, a reira i taea anake te i titiro rite te otinga ariā ki te raruraru. i te mutunga rawa o te rau tau anake i mua whakamutunga i whakaaro he tikanga e whakaaetia ana ki te whakatū i te hanga atu economical o acetylene. hāngai ana tēnei tikanga i runga i te pātīmata o te ranunga tënei o kotakota tere , me te waro. Tenei ka arahi ki te whakamahi o te pūhui rite te hau mo te rama huarahi. Ko te take i te hau e kei roto i tona hanganga e pā ana ki 92,3% o te waro, i te pāmahana teitei puha nui o tenei taonga kia rite ki te totoka. E hoatu ana e ratou he marama tika kanapa. I roto i tenei take i te pāmahana ngingiha whakatau kore anake te parariraa wherikotanga, engari tona tae. Ko te pāmahana teitei - rawa tae luminescence tu'o ko matūriki waro. Puta mahana, i taea e āhua rima nga wa neke atu i noa ka rama hau hoatu te marama ki tonu i te acetylene. Ahakoa, i te whakakapi ratou i te rama hiko, whakamahia acetylene mō te rama tonu ki rama pahikara me omnibuses.

Ka rite ki te whanaketanga o te ahumahi, e hiahiatia katoa nui o taua pūhui rite acetylene. Whiwhi i te reira i runga i te tauine ahumahi anga anake i roto i te rau tau whakamutunga. Ka rite ki te hua o taua he "pakaruhanga", ka anga te hononga ki te kia whakamahia mō ngā take hangarau. Hoki ngā take hanga carbide acetylene whiwhi e tinei ki te wai. Kei te mohiotia tenei hua mo ona rawa tokomaha kakara kino e tika ana ki poke i roto i roto i taua mea o te haukini me te hauwai sulfide. I roto i te meka, te taonga parakore matū kua he kakara ethereal ngonge korerotia. he māmā ake i te hau, te taimaha o te rāpoi he acetylene 26,038. Ko Gas taekore, he ngāwari wairewa i roto i maha rongoā wai, te memehatanga i whakaritea e te pāmahana o te otinga.

hangarau o nāianei whakarato hoki whiwhi acetylene i mewaro i elektrokrekinga - he tukanga i roto i nei te tuatahi te kawehiko haere te haurehu mewaro i te pāmahana kahore i raro i 1600 ° C. Na, ki te ārai i raro whāwehe o te hau acetylene te ki tautauā tere. Ko whai hua i roto i taua he wahi o te wera whiwhi e te parariraa o te taonga e taea te whakahaua ki te para i te huringa tauhohe muri, whakarato tonu o tona akoranga tenei tikanga.

Kei te whānui Acetylene whakamahia i roto i te fehokotaki'anga, me te tapahi konganuku, ki te whiwhi i te marama ma rawa kanapa, mo te hanga o ngā rauemi taikaha.
