Acetylene (C2H2)

Ibipimo bya tekiniki

Acetylene, molekuline ya C2H2, ikunze kwitwa amakara yumuyaga cyangwa gaze kariside ya kariside, ni umunyamuryango muto muto wa alkyne.Acetylene ni gaze itagira ibara, uburozi bworoheje na gaze yaka cyane ifite anesthetic nkeya na anti-okiside munsi yubushyuhe busanzwe nigitutu.Irashobora gushonga gato mumazi, gushonga muri Ethanol, benzene, na acetone.Acetylene yuzuye ntabwo ihumura, ariko acetylene yinganda ifite impumuro ya tungurusumu kuko irimo umwanda nka hydrogen sulfide na fosifine.Acetylene yuzuye ni gaze itagira ibara kandi ihumura neza.Irashobora guturika bikabije mumazi kandi akomeye cyangwa mumyuka ya gaze hamwe nigitutu runaka.Ibintu nkubushyuhe, kunyeganyega, hamwe n’umuriro w'amashanyarazi birashobora gutera igisasu, bityo ntigishobora gutwarwa nigitutu.Kubika cyangwa gutwara.Kuri 15 ° C na 1.5MPa, gukomera muri acetone ni hejuru cyane, hamwe no gukomera kwa 237g / L, bityo acetylene yinganda ni acetylene yashonga muri acetone, nayo bita acetylene yashonze.Kubwibyo, mu nganda, muri silinderi yicyuma yuzuyemo ibikoresho byoroshye nka asibesitosi, acetylene ikanda mubintu byoroshye nyuma yo kwinjiza acetone yo kubika no gutwara.Gazi ya Acetylene irashobora gutanga ubushyuhe bwinshi iyo yatwitse.Ubushyuhe bwumuriro wa oxyacetylene burashobora kugera kuri 3200 ℃.Bikunze gukoreshwa mugukata ibyuma nko kubaka ubwato no kubaka ibyuma;ikoreshwa muri synthesis organique (gukora acetaldehyde, acide acetike, benzene, reberi yubukorikori, fibre synthique, nibindi), ubuvuzi bwa sintetike nubuvuzi bwa vinyl acetylene cyangwa divinyl acetylene;ikoreshwa mu kubyara imyuka isanzwe nka transfert ya peteroli isesengura gaze isanzwe.Umwuka mwinshi wa acetylene ukoreshwa mukwinjiza atome nibindi bikoresho.Uburyo bwo gupakira bwa acetylene mubusanzwe bushonga mumashanyarazi nibikoresho byoroshye hanyuma byuzuzwa silinderi y'ibyuma.Ubike mu bubiko bukonje, buhumeka.Irinde umuriro nubushyuhe.Ubushyuhe bwo kubika ntibugomba kurenga 30 ° C.Igomba kubikwa ukwayo na okiside, acide, na halogene, kandi ikirinda ububiko buvanze.Koresha amatara adashobora guturika no guhumeka.Birabujijwe gukoresha ibikoresho bya mashini nibikoresho bikunda kugaragara.Ahantu ho guhunika hagomba kuba hafite ibikoresho byo kuvura byihutirwa.

Gusaba:

Gutema no gusudira ibyuma:

Iyo acetylene yaka, irashobora gutanga ubushyuhe bwinshi.Ubushyuhe bwumuriro wa oxyacetylene burashobora kugera kuri 3200 ℃, bukoreshwa mugukata no gusudira ibyuma.

Materials Ibikoresho fatizo bya shimi:

Acetylene ni ibikoresho fatizo byibanze byo gukora acetaldehyde, aside acike, benzene, reberi yubukorikori, hamwe na fibre synthique.

③ Ubushakashatsi

Acetylene yuzuye irashobora gukoreshwa mubushakashatsi bumwe.
