Acetylene, caanaha molecular C2H2, oo loo yaqaan dhuxusha dabaysha ama gaaska carbide calcium, waa xubinta ugu yar ee xeryahooda alkyne. Acetylene waa gaas aan midab lahayn, wax yar sun ah oo aad u guban kara oo leh suuxin daciif ah iyo saamaynta ka-hortagga oksaydhka ee heerkulka caadiga ah iyo cadaadiska. Wax yar bay ku milmi kartaa biyaha, waxay ku milmi kartaa ethanol, benzene, iyo acetone. Acetylene saafi ah ma ur, laakiin acetylene warshadaha waxay leedahay urta toonta sababtoo ah waxay ka kooban tahay wasakh sida hydrogen sulfide iyo phosphine. acetylene saafi ah waa gaas ololaysa oo aan midab lahayn iyo caraf udgoon. Waxa laga yaabaa inay si xoog leh ugu qaraxdo dareere iyo xaalad adag ama xaalad gaas ah iyo cadaadis gaar ah. Waxyaalaha ay ka midka yihiin kulaylka, gariirka, iyo dhimbiil koronto ayaa sababi kara qarax, sidaas darteed cadaadis laguma shubi karo. Kaydinta ama gaadiidka. Marka la joogo 15°C iyo 1.5MPa, milanka acetone waa mid aad u sarreeya, oo milmidiisu tahay 237g/L, sidaa darteed acetylene warshaduhu waa acetylene oo lagu milmay acetone, oo sidoo kale loo yaqaanno acetylene milmay. Sidaa darteed, warshadaha, dhululubo bir ah oo ay ka buuxaan walxo dalool ah sida asbestos, acetylene ayaa lagu cadaadiyaa walxaha daloola ka dib marka la nuugo acetone ee kaydinta iyo gaadiidka. Gaaska acetylene wuxuu soo saari karaa heerkul sare marka la gubo. Heerkulka ololka oxyacetylene wuxuu gaari karaa ilaa 3200 ℃. Inta badan waxaa loo isticmaalaa jarista birta sida dhismaha maraakiibta iyo qaabka birta; waxaa loo isticmaalaa isku-dhafka dabiiciga ah (samaynta acetaldehyde, acetic acid, benzene, caag synthetic, fiilooyinka synthetic, iwm.), Dawada synthetic iyo dhexdhexaadinta kiimikada vinyl acetylene ama divinyl acetylene; loo isticmaalo in lagu soo saaro gaaska caadiga ah sida gaaska caadiga ah ee falanqaynta saliidda transformer. Gaaska acetylene ee nadiifka sare ah waxaa loo isticmaalaa nuugista atomiga iyo qalabyada kale. Habka baakadaha ee acetylene waxaa inta badan lagu milmaa dareerayaasha iyo alaabta daloolsan waxaana lagu buuxiyaa dhululubada birta ah. Ku kaydi bakhaar qabow oo hawo leh. Ka fogow dabka iyo ilaha kulaylka. Heerkulka kaydinta waa inuusan dhaafin 30 ° C. Waa in si gooni ah loo kaydiyaa oksaydhiyeyaasha, acids, iyo halogens, kana fogaato kaydinta isku dhafan. Isticmaal nalalka aan qarxin iyo tas-hiilaadka hawo-siinta. Waa mamnuuc in la isticmaalo qalabka farsamada iyo qalabka u nugul dhinbiilka. Aagga kaydinta waa in lagu qalabeeyaa qalabka daaweynta degdega ah ee daadsan.
①Goynta iyo alxanka birta:
Marka acetylene gubato, waxay soo saari kartaa heerkul sare. Heerkulka ololka oxyacetylene wuxuu gaari karaa ilaa 3200 ℃, kaas oo loo isticmaalo goynta iyo alxanka biraha.
②Waxyaabaha ceeriinka ah ee kiimikada aasaasiga ah:
Acetylene waa alaabta asaasiga ah ee soo saarida acetaldehyde, acetic acid, benzene, caag synthetic, iyo fiilooyinka synthetic.
③ Tijaabada
Nadiifinta sare ee acetylene waxaa loo isticmaali karaa tijaabooyinka qaarkood.
