I-Acetylene (C2H2)

Iiparameter zobugcisa

I-Acetylene, ifomula yemolekyuli i-C2H2, eyaziwa ngokuba yi-wind coal okanye i-calcium carbide gas, lelona lungu lincinci kwiikhompawundi ze-alkyne. I-Acetylene yigesi engenambala, inetyhefu kancinci kwaye itsha kakhulu ene-anesthetic ebuthathaka kunye ne-anti-oxidation effects phantsi kobushushu obuqhelekileyo kunye noxinzelelo. Inyibilika kancinci emanzini, inyibilika kwi-ethanol, i-benzene, kunye ne-acetone. I-acetylene ecocekileyo ayinavumba, kodwa i-acetylene yezimboni inevumba legalikhi kuba iqulethe ukungcola okufana ne-hydrogen sulfide kunye ne-phosphine. I-acetylene ecocekileyo yigesi engenambala nenuka kamnandi. Ingaqhuma ngamandla kwimeko yolwelo kunye neyomeleleyo okanye kwimeko yegesi kunye noxinzelelo oluthile. Izinto ezifana nobushushu, ukungcangcazela, kunye ne-spark yombane zinokubangela ukuqhuma, ngoko ke ayinakunyibilika phantsi koxinzelelo. Ukugcinwa okanye ukuthuthwa. Kwi-15°C kunye ne-1.5MPa, ukunyibilika kwi-acetone kuphezulu kakhulu, kunye nokunyibilika kwe-237g/L, ngoko ke i-acetylene yemizi-mveliso yi-acetylene enyibilikiswe kwi-acetone, ekwabizwa ngokuba yi-acetylene enyibilikisiweyo. Ke ngoko, kushishino, kwiisilinda zentsimbi ezizaliswe zizinto ezinemingxuma ezifana ne-asbestos, i-acetylene icinezelwa kwizinto ezinemingxuma emva kokufunxa i-acetone yokugcina kunye nokuthutha. Igesi ye-acetylene inokuvelisa ubushushu obuphezulu xa itshiswa. Ubushushu belangatye le-oxyacetylene bunokufikelela malunga ne-3200℃. Ihlala isetyenziselwa ukusika isinyithi njengokwakha iinqanawa kunye nesakhiwo sentsimbi; isetyenziselwa ukwenziwa kwezinto eziphilayo (ukwenza i-acetaldehyde, i-acetic acid, i-benzene, irabha yokwenziwa, iifayibha zokwenziwa, njl.njl.), amayeza okwenziwa kunye neekhemikhali eziphakathi kwe-vinyl acetylene okanye i-divinyl acetylene; isetyenziselwa ukuvelisa iigesi eziqhelekileyo ezifana nohlalutyo lweoyile ye-transformer standard gas. Igesi ye-acetylene ecocekileyo kakhulu isetyenziselwa ukufunxa i-atomic kunye nezinye izixhobo. Indlela yokupakisha i-acetylene idla ngokunyibilika kwizinyibilikisi nakwizinto ezinemingxuma ize izaliswe kwiisilinda zentsimbi. Gcina kwindawo yokugcina izinto epholileyo, enomoya opholileyo. Gcina kude nomlilo kunye nemithombo yobushushu. Ubushushu bokugcina akufuneki budlule kwi-30°C. Kufuneka igcinwe ngokwahlukileyo kwii-oxidants, ii-asidi, kunye nee-halogens, kwaye uphephe ukugcinwa okuxutyiweyo. Sebenzisa izixhobo zokukhanyisa ezithintela ukuqhuma kunye nokungenisa umoya. Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezinokuba neentlantsi. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo.

Isicelo:

①Ukusika nokuwelda isinyithi:

Xa i-acetylene itsha, inokuvelisa ubushushu obuphezulu. Ubushushu belangatye le-oxyacetylene bunokufikelela kuma-3200℃, elisetyenziselwa ukusika nokuwelda iintsimbi.

②Izinto ezisisiseko zekhemikhali:

I-acetylene sisixhobo esisisiseko sokwenza i-acetaldehyde, i-acetic acid, i-benzene, irabha yokwenziwa, kunye neefayibha zokwenziwa.

③ Uvavanyo

I-acetylene ecocekileyo kakhulu ingasetyenziswa kwezinye iimvavanyo.
