Me pēhea te ki te tiki i te mewaro, acetylene

I roto i te tikanga ki te whiwhi mewaro o acetylene, he mea e tika ana ki te whakahaere i te tauhohenga dehydrogenation. I mua i eke i runga i tona arotake, tātari etahi pūwaro ngā.

Āhuatanga o te acetylene

Tenei taonga haurehu waihā, e ko te māngai tuatahi o te piha haapiiraa o waiwaro hamanga (alkynes). he māmā ake i te hau, he ruarua wairewa i roto i te wai. Rāpoi tātai C ₂ H _2, noa ki te piha haapiiraa katoa SPN ₂ n-2. whakaaro Acetylene te matū kaha, haunga tino taikaha. I roto i te tikanga ki te karo i ngā āhuatanga ohorere, kei te rongoa reira i roto i ipu maitai hiri, tāpiri ki reira waro.

Whiwhi i waiwaro tahi

Ki runga ki whāwehe o te mewaro acetylene whiwhi. kawea ana tēnei tauhohenga matū i roto i te whakamahi i te whakakōkī puta i te pāmahana a'e. tu te rauemi tīmata piha tuatahi paraffins māngai. A, no te dehydrogenation, tua o te acetylene, hangaia hauwai te.

Te whakautu ki te pātai e pā ana ki te pehea, ki te tiki i te mewaro, acetylene, māngai te whārite tauhohenga e i roto i te puka:

2SN4 = C2H2 + 3H2

tikanga carbide

Ka taea e te tiki tetahi i te mewaro acetylene ranei rite te rauemi tīmata ki te tango i te carbide konupūmā. e te tukanga wahi i raro i ngā āhuatanga ambient. I roto i te tauhohenga o te konupūmā carbide ki te wai i hanga te kore acetylene anake, engari konupūmā waihā (kotakota slaked). ka rere tohumate tukanga matū kukuwhatanga hau (hi), me te huringa i roto i te tae o te otinga mā te tāpiri waipūhuitohukonu i runga i te tae whero.

A, no te tono rite rauemi tīmatanga he carbide hangarau he ngā poke, kitea kakara i roto i te tauhohenga. faataa ia e te aroaro i roto i te hua tauhohe o taua hau paitini rite phosphine, hauwai sulfide.

papatanga hinu

I tēnei wā, e kore e taea te tiki noa koutou i roto i o mewaro, acetylene. whakaaro te tikanga ahumahi matua o te hanga o te māngai o te waiwaro toru e ki hangai (wāhinga) o waiwaro. Ki te riro mai acetylene mewaro, ka kia iti nga utu pūngao. I tua atu ki ngā rauemi raw ngāwari, me te wātea, kua ngā tenei hangarau kaihanga o waiwaro tapatahi o ngā taputapu hangarau e whakamahia ana i roto i te dehydrogenation o te mewaro.

E rua putanga o te tukanga matū rite. hāngai ana te tikanga tuatahi i runga i haere i te mewaro i roto i te electrodes, wera ki te 1600 degrees. Ko te tikanga tā tinei i te hua hua. Tuarua dehydrogenation ahua o te mewaro ki te whakaputa i acetylene tā te whakamahi o te pūngao, whakaputaina nei e ngingiha wāhanga o te waiwaro toru.

e kore e taea te rawa ipurau e roto i acetylene, ki vaolo parahi, rite kei te wāhanga o te parahi parahi. haere tahi te pāhekoheko o te whakarewa ki te tukua acetylene e tote taikaha.

mutunga

Kei te whakamahia i tēnei wā Acetylene i ngā mara ahumahi. Ko te rauemi raw tino mo te kōtuitui o te waihā, kirihou, rubbers, waikawa ahetiki. Māngai o tenei piha kī alkynes mō te tapahi me te fehokotaki'anga konganuku, ka rite ki te marama kanapa i roto i te huaki rama takitahi.

I runga i te pūtake o te ariā acetylene kawea te explosives whakamahia i roto i te puka o detonators. kitea te tauhohenga piti hāora o te waiwaro toru o te hāora i roto i te rangi ko te mura kaha. O te uara rite ko te ahumahi matū me te mewaro. Haunga tona tono rite te rauemi tīmata mo te hanga o te acetylene, kua pau te reira i roto i te nui rite te pūwaro tūturu i roto i te ahumahi wahie. tohaina he nui nui o te wera, no te tahuna.
