Hydrogen Chloride (HCl)

Zofunika zaukadaulo:

Hydrogen chloride ili ndi formula ya mankhwala HCl. Molekyu ya hydrogen chloride imapangidwa ndi atomu ya chlorine ndi atomu ya haidrojeni. Ndi gasi wopanda mtundu wokhala ndi fungo loyipa. Gasi wowononga, wosayaka, samachita ndi madzi koma amasungunuka mosavuta m'madzi. Nthawi zambiri amapezeka mumlengalenga ngati mpweya wa hydrochloric acid. Hydrogen chloride imasungunuka mosavuta mu ethanol ndi ether, komanso kusungunuka muzinthu zina zambiri zamoyo; Zosungunuka mosavuta m'madzi, pa 0 ° C, voliyumu imodzi yamadzi imatha kusungunula pafupifupi ma voliyumu 500 a hydrogen chloride. Njira yake yamadzimadzi imadziwika kuti hydrochloric acid, ndipo dzina lake lasayansi ndi hydrochloric acid. Concentrated hydrochloric acid ndi osakhazikika. Hydrogen chloride ndi yopanda mtundu, ndipo imasungunuka -114.2 ° C ndi kuwira kwa -85 ° C. Sichiwotcha mumlengalenga ndipo chimakhala chokhazikika. Sichiwola mpaka pafupifupi 1500 ° C. Lili ndi fungo losautsa, limapsa mtima kwambiri m'mwamba, limawononga maso, khungu ndi mucous nembanemba. Kuchulukana kwake ndi kwakukulu kuposa mpweya. The mankhwala katundu wa dry hydrogen kolorayidi sagwira ntchito kwambiri. Zitsulo za alkali ndi zitsulo zamchere zapadziko lapansi zimatha kuyaka mu hydrogen chloride, ndipo sodium ikayaka, imatulutsa lawi lowala lachikasu. Hydrogen chloride imagwiritsidwa ntchito pamakampani a petrochemical kulimbikitsa mphamvu ndi kusinthika kwazinthu zopangira ndikuwonjezera kukhuthala kwamafuta; itha kugwiritsidwa ntchito kupanga chlorosulfonic acid, mphira wopangira, etc.; itha kugwiritsidwanso ntchito popanga utoto, zonunkhiritsa, kaphatikizidwe ka mankhwala, ma chloride osiyanasiyana ndi zoletsa dzimbiri, komanso kuyeretsa, Pickling, electroplating zitsulo, kufufuta, kuyenga kapena kupanga zitsulo zolimba. Mpweya woyeretsedwa kwambiri wa hydrogen chloride umagwiritsidwa ntchito kwambiri pakukula kwa silicon epitaxial, kupukuta gawo la nthunzi, kutulutsa, kupukuta ndi kuyeretsa mumakampani amagetsi.

Ntchito:

①Zinthu:

Mafuta ambiri a hydrogen chloride amagwiritsidwa ntchito popanga hydrochloric acid. Komanso ndi reagent yofunika mu mafakitale ena kusintha mankhwala.

②Semiconductor:

M'makampani a semiconductor, amagwiritsidwa ntchito popanga ma etch semiconductor crystals ndikuyeretsa silicon kudzera pa trichlorosilane (SiHCl3).

③Labu:

Mu labotale, mitundu ya mpweya wa anhydrous ndiyothandiza kwambiri popanga ma Lewis acid okhala ndi chloride, omwe ayenera kukhala owuma kuti malo awo a Lewis agwire ntchito.

Phukusi labwinobwino:

Ubwino:

①Kuyera kwakukulu, malo aposachedwa;

② ISO wopanga satifiketi;

③Kutumiza mwachangu;

④Dongosolo lowunikira pa intaneti pakuwongolera kwamtundu uliwonse;

⑤Kufunika kwakukulu ndi njira yosamala yogwiritsira ntchito silinda musanadzaze;
