Acetylene (C2H2)

Teknụzụ paramita

Acetylene, usoro molekul C2H2, nke a maara dịka ikuku coal ma ọ bụ calcium carbide gas, bụ obere ihe mejupụtara alkyne. Acetylene bụ gas na-enweghị agba, nke na-egbu egbu ntakịrị ma na-ere ọkụ nke ukwuu, nke nwere mmetụta na-adịghị ike na mgbochi oxidation n'okpuru okpomọkụ na nrụgide nkịtị. Ọ na-agbaze ntakịrị na mmiri, ọ na-agbaze na ethanol, benzene, na acetone. Acetylene dị ọcha enweghị isi, mana acetylene ụlọ ọrụ mmepụta ihe nwere isi galik n'ihi na o nwere ihe ndị na-adịghị mma dị ka hydrogen sulfide na phosphine. Acetylene dị ọcha bụ gas na-enweghị agba na nke na-ere ọkụ na-esi ísì ụtọ. Ọ nwere ike ịgbawa nke ukwuu n'ọnọdụ mmiri mmiri na nke siri ike ma ọ bụ n'ọnọdụ gas na nrụgide ụfọdụ. Ihe ndị dị ka okpomọkụ, ịma jijiji, na ọkụ eletrik nwere ike ibute mgbawa, yabụ enweghị ike ịgbaze ya n'okpuru nrụgide. Nchekwa ma ọ bụ njem. Na 15°C na 1.5MPa, mgbaze na acetone dị oke elu, yana mgbaze nke 237g/L, yabụ acetylene ụlọ ọrụ mmepụta ihe bụ acetylene agbazere na acetone, nke a na-akpọkwa acetylene agbazere. Ya mere, n'ime ụlọ ọrụ mmepụta ihe, na silinda ígwè jupụtara na ihe ndị nwere oghere dị ka asbestos, a na-etinye acetylene n'ime ihe nwere oghere mgbe ọ na-amịkọrọ acetone maka nchekwa na njem. Gas Acetylene nwere ike imepụta okpomọkụ dị elu mgbe ọkụ gbara ya. Okpomọkụ nke ire ọkụ oxacetylene nwere ike iru ihe dị ka 3200℃. A na-ejikarị ya eme ihe maka ịkpụ ígwè dịka iwu ụgbọ mmiri na nhazi ígwè; a na-eji ya eme ihe maka njikọta organic (ime acetaldehyde, acetic acid, benzene, roba sịntetik, eriri sịntetik, wdg), ọgwụ sịntetik na ihe ndị dị n'etiti kemịkalụ vinyl acetylene ma ọ bụ divinyl acetylene; a na-eji ya emepụta gas ọkọlọtọ dị ka gas ọkọlọtọ nyocha mmanụ transformer. A na-eji gas acetylene dị ọcha nke ukwuu maka nnabata atọm na ngwa ndị ọzọ. A na-agbazekarị usoro nkwakọ ngwaahịa nke acetylene na ihe mgbaze na ihe ndị nwere oghere ma jupụta ya na silinda ígwè. Debe ya n'ụlọ nkwakọba ihe dị jụụ, nke ikuku na-efe efe. Debe ya ebe ọkụ na ebe ọkụ na-esi. Okpomọkụ nchekwa ekwesịghị ịgafe 30°C. Ekwesịrị ịchekwa ya iche na oxidants, acids, na halogens, ma zere nchekwa agwakọtara. Jiri ihe ndị na-enye ọkụ na ikuku na-anaghị agbawa agbawa. A machibidoro iji ngwa ọrụ na ngwaọrụ ndị nwere ike ibute ọkụ. Ebe nchekwa ahụ kwesịrị inwe ngwa ọgwụgwọ mberede na-agbapụta mmiri.

Ngwa:

① Ịkpụ na ịgbado ígwè:

Mgbe acetylene gbara ọkụ, ọ nwere ike imepụta okpomọkụ dị elu. Okpomọkụ nke ire ọkụ oxyacetylene nwere ike iru ihe dị ka 3200℃, nke a na-eji egbutu ma na-agbado ígwè.

②Ihe ndị bụ isi gbasara kemịkalụ:

Acetylene bụ ihe e ji emepụta acetaldehyde, acetic acid, benzene, roba sịntetik, na eriri sịntetik.

③ Nnwale

Enwere ike iji acetylene dị ọcha nke ukwuu na ụfọdụ nnwale.
