Acetylene (C2H2)

Technical parameters

Acetylene, molecular formula C2H2, inowanzozivikanwa semhepo marasha kana calcium carbide gasi, ndiyo inhengo diki yealkyne makomisheni. Acetylene igasi risina ruvara, rine muchetura uye rinopisa zvakanyanya uye ine simba reanesthetic uye anti-oxidation mhedzisiro pasi peyakajairika tembiricha uye kumanikidzwa. Inonyungudika zvishoma mumvura, inonyungudika mu ethanol, benzene, uye acetone. Acetylene yakachena hainhuhwi, asi maindasitiri acetylene ane hwema hwegariki nekuti ine tsvina yakaita sehydrogen sulfide nephosphine. Pure acetylene igasi risina ruvara uye rinonhuwirira rinobvira moto. Inogona kuputika zvine chisimba mumvura uye yakasimba mamiriro kana mune gasi uye kumwe kudzvanywa. Zvinhu zvakadai sekupisa, kuzunguzika, uye spark yemagetsi zvinogona kukonzera kuputika, saka haigone kunyungudutswa pasi pekumanikidzwa. Kuchengeta kana kufambisa. Pa15 ° C uye 1.5MPa, kunyungudika muacetone kwakakwira zvakanyanya, nekunyungudika kwe237g/L, saka maindasitiri acetylene iacetylene yakanyungudika muacetone, inonziwo yakanyungudika acetylene. Naizvozvo, muindasitiri, mumasilinda esimbi akazadzwa nezvinhu zvine porous senge asbestos, acetylene inotsikirirwa mukati meiyo porous zvinhu mushure mekutora acetone yekuchengetedza uye kutakura. Acetylene gasi inogona kuburitsa kupisa kwakanyanya kana yapiswa. Tembiricha ye oxyacetylene murazvo inogona kusvika 3200 ℃. Inowanzoshandiswa kutema simbi yakadai sekuvaka ngarava uye chimiro chesimbi; inoshandiswa pakugadzira organic synthesis (kugadzira acetaldehyde, acetic acid, benzene, synthetic rubber, synthetic fibers, etc.), Mushonga weSynthetic nemakemikari epakati vinyl acetylene kana divinyl acetylene; inoshandiswa kugadzira magasi akajairwa senge transformer oiri yekuongorora yakajairwa gasi. Yakakwirira-kuchena acetylene gasi inoshandiswa kunyura atomu uye zvimwe zviridzwa. Iyo yekurongedza nzira yeacetylene inowanzonyungudika mune zvinonyungudutsa uye porous zvinhu uye inozadzwa mumasilinda esimbi. Chengetedza muimba yekuchengetera inotonhorera, ine mhepo. Ramba kure nemoto nekupisa. Tembiricha yekuchengetera haifanirwe kudarika 30°C. Inofanirwa kuchengetwa zvakasiyana kubva kune oxidants, acids, uye halogens, uye kudzivirira zvakasanganiswa kuchengetedza. Shandisa mwenje unodzivirira kuputika uye nzvimbo dzekupinza mhepo. Zvinorambidzwa kushandisa michina michina uye maturusi anowanzo kupfava. Nzvimbo yekuchengetera inofanirwa kunge yakashongedzerwa neyakadonha yekurumidzira kurapwa michina.

Application:

①Kucheka uye kupinza simbi:

Kana acetylene ichipisa, inogona kuburitsa kupisa kwakanyanya. Tembiricha ye oxyacetylene murazvo inogona kusvika pa 3200 ℃, iyo inoshandiswa kucheka nekuisa simbi.

②Basic kemikari mbishi zvinhu:

Acetylene ndiyo yakakosha midziyo yekugadzira acetaldehyde, acetic acid, benzene, synthetic rubber, uye mafiber ekugadzira.

③ Kuedza

High kuchena acetylene inogona kushandiswa mune zvimwe zviedzo.
