Acetylene (C2H2)

Technical parameters

Acetylene, molecular mis C2H2, feem ntau hu ua cua thee lossis calcium carbide gas, yog tus tswv cuab tsawg tshaj plaws ntawm alkyne tebchaw. Acetylene yog xim tsis muaj xim, me ntsis tshuaj lom thiab tsis tshua muaj hluav taws kub nrog cov tshuaj loog tsis muaj zog thiab tiv thaiv oxidation los ntawm qhov kub thiab txias. Nws yog me ntsis soluble hauv dej, soluble hauv ethanol, benzene, thiab acetone. Ntshiab acetylene tsis muaj ntxhiab, tab sis muaj acetylene muaj ntxhiab tsw ntawm qej vim nws muaj impurities xws li hydrogen sulfide thiab phosphine. Ntshiab acetylene yog cov roj uas tsis muaj xim thiab muaj ntxhiab tsw ntxhiab tsw. Nws tuaj yeem tawg hnyav hauv cov kua thiab cov khoom hauv lub xeev lossis hauv lub xeev gaseous thiab qee qhov siab. Cov yam ntxwv xws li cua sov, kev vibration, thiab hluav taws xob hluav taws xob tuaj yeem ua rau tawg, yog li nws tsis tuaj yeem ua kua dej hauv lub siab. Kev khaws cia lossis kev thauj mus los. Ntawm 15 ° C thiab 1.5MPa, solubility hauv acetone yog qhov siab heev, nrog rau solubility ntawm 237g / L, yog li kev lag luam acetylene yog acetylene yaj hauv acetone, kuj hu ua yaj acetylene. Yog li ntawd, nyob rau hauv kev lag luam, nyob rau hauv steel cylinders ntim nrog cov khoom ntxeem tau xws li asbestos, acetylene yog nias rau hauv cov khoom ntxeem tau tom qab absorbing acetone rau kev cia thiab kev thauj mus los. Acetylene gas tuaj yeem ua rau kub kub thaum hlawv. Qhov kub ntawm oxyacetylene nplaim tuaj yeem ncav cuag li 3200 ℃. Nws yog feem ntau siv rau kev txiav hlau xws li nkoj tsim thiab steel qauv; nws yog siv rau cov organic synthesis (ua acetaldehyde, acetic acid, benzene, hluavtaws roj hmab, hluavtaws fibers, thiab lwm yam.), Synthetic tshuaj thiab tshuaj intermediates vinyl acetylene los yog divinyl acetylene; siv los tsim cov qauv gases xws li transformer roj tsom xam cov qauv roj. High-purity acetylene gas yog siv rau atomic absorption thiab lwm yam twj paj nruag. Cov txheej txheem ntim ntawm acetylene feem ntau yog yaj hauv cov kuab tshuaj thiab cov khoom ntxeem tau thiab ntim rau hauv cov thooj voos kheej kheej steel. Khaws rau hauv qhov chaw txias, ventilated warehouse. Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub. Qhov kub cia yuav tsum tsis pub tshaj 30 ° C. Nws yuav tsum tau muab cais los ntawm oxidants, acids, thiab halogens, thiab tsis txhob sib xyaw cia. Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab qhov cua qhov cua. Nws yog txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas ua rau muaj qhov ci ntsa iab. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev.

Daim ntawv thov:

① Txiav thiab vuam hlau:

Thaum acetylene hlawv, nws tuaj yeem ua rau kub kub. Qhov kub ntawm oxyacetylene nplaim tuaj yeem ncav cuag li 3200 ℃, uas yog siv rau kev txiav thiab vuam hlau.

②Basic chemical raw khoom:

Acetylene yog cov khoom siv tseem ceeb rau kev tsim cov acetaldehyde, acetic acid, benzene, hluavtaws roj hmab, thiab hluavtaws fibers.

③ Kev sim

High purity acetylene tuaj yeem siv rau hauv qee qhov kev sim.
