Hydrogen Chloride (HCl)

Technical Parameters:

Hydrogen chloride muaj cov tshuaj formula HCl. Lub hydrogen chloride molecule yog tsim los ntawm chlorine atom thiab hydrogen atom. Nws yog ib qho tsis muaj xim tsis muaj roj nrog cov ntxhiab tsw. Corrosive, uas tsis yog-combustible gas, tsis hnov ​​​​mob nrog dej tab sis yooj yim soluble hauv dej. Nws feem ntau tshwm sim hauv huab cua hauv daim ntawv ntawm hydrochloric acid fumes. Hydrogen chloride yog yooj yim soluble nyob rau hauv ethanol thiab ether, thiab kuj soluble nyob rau hauv ntau lwm yam organic tshuaj; yooj yim heev soluble hauv dej, ntawm 0 ° C, 1 ntim dej tuaj yeem yaj kwv yees li 500 ntim ntawm hydrogen chloride. Nws cov tshuaj aqueous feem ntau hu ua hydrochloric acid, thiab nws lub npe tshawb fawb yog hydrochloric acid. Concentrated hydrochloric acid yog volatile. Hydrogen chloride yog xim tsis muaj xim, nrog lub melting point ntawm -114.2 ° C thiab boiling point ntawm -85 ° C. Nws tsis hlawv hauv huab cua thiab yog thermally ruaj khov. Nws tsis decompose mus txog 1500 ° C. Nws muaj cov ntxhiab tsw tsw, muaj zog ua rau mob rau sab sauv ua pa, thiab ua rau lub qhov muag, tawv nqaij thiab mucous daim nyias nyias. Qhov ceev yog ntau dua li huab cua. Cov khoom siv tshuaj lom neeg ntawm qhuav hydrogen chloride tsis ua haujlwm heev. Alkali hlau thiab alkaline ntiaj teb hlau tuaj yeem hlawv hauv hydrogen chloride, thiab thaum sodium hlawv, nws tawm cov nplaim daj daj. Hydrogen chloride yog siv nyob rau hauv kev lag luam petrochemical los txhawb kev ua tau zoo thiab rov tsim dua tshiab ntawm cov catalysts thiab nce cov viscosity ntawm roj av; nws tuaj yeem siv los tsim chlorosulfonic acid, hluavtaws roj hmab, thiab lwm yam .; Nws kuj tseem siv tau los ua dyes, fragrances, tshuaj synthesis, ntau yam chlorides thiab corrosion inhibitors, thiab huv si, Pickling, electroplating hlau, tanning, refining los yog manufacturing hard hlau. High-purity hydrogen chloride gas yog dav siv nyob rau hauv silicon epitaxial kev loj hlob, vapor theem polishing, tau txais, etching thiab tu txheej txheem nyob rau hauv lub electronics kev lag luam.

Daim ntawv thov:

① Khoom siv:

Feem ntau hydrogen chloride yog siv los tsim cov hydrochloric acid. Nws kuj yog ib qho tseem ceeb reagent nyob rau hauv lwm yam industrial chemical transformations.

② Semiconductor:

Hauv kev lag luam semiconductor, nws yog siv rau ob qho tib si etch semiconductor crystals thiab purify silicon ntawm trichlorosilane (SiHCl3).

③ Laboratory:

Hauv chav kuaj, cov ntaub ntawv tsis muaj dej ntawm cov pa roj tshwj xeeb yog qhov tseem ceeb rau kev tsim cov tshuaj chloride-raws li Lewis acids, uas yuav tsum tau qhuav kiag li rau lawv qhov chaw Lewis ua haujlwm.
