Hydrogen Chloride (HCl)

Sigogi na Fasaha:

Hydrogen chloride yana da dabarar sinadarai ta HCl. Kwayar hydrogen chloride ta ƙunshi kwayar chlorine da kuma kwayar hydrogen. Iska ce mara launi mai ƙamshi mai kamshi. Iskar gas mai laushi, wadda ba ta ƙonewa, ba ta amsawa da ruwa amma tana narkewa cikin sauƙi a cikin ruwa. Sau da yawa tana nan a cikin iska a cikin nau'in hayakin hydrochloric acid. Hydrogen chloride yana narkewa cikin sauƙi a cikin ethanol da ether, kuma yana narkewa cikin wasu abubuwa masu rai da yawa; yana narkewa cikin sauƙi a cikin ruwa, a 0°C, ruwa 1 na iya narke kimanin lita 500 na hydrogen chloride. Maganin ruwansa galibi ana kiransa hydrochloric acid, kuma sunan kimiyya shine hydrochloric acid. Hydrochloric acid mai ƙarfi yana canzawa. Hydrogen chloride ba shi da launi, tare da wurin narkewa na -114.2°C da kuma wurin tafasa na -85°C. Ba ya ƙonewa a cikin iska kuma yana da karko a yanayin zafi. Ba ya ruɓewa har sai kusan 1500°C. Yana da ƙamshi mai shaƙewa, yana da ƙaiƙayi mai ƙarfi ga hanyar numfashi ta sama, kuma yana lalata idanu, fata da membranes na mucous. Yawansa ya fi iska yawa. Abubuwan sinadarai na busasshen hydrogen chloride ba su da aiki sosai. Karafan Alkali da ƙarfe na ƙasa na alkaline na iya ƙonewa a cikin hydrogen chloride, kuma lokacin da sodium ya ƙone, yana fitar da harshen wuta mai haske. Ana amfani da hydrogen chloride a masana'antar petrochemical don haɓaka inganci da sake farfaɗo da abubuwan kara kuzari da ƙara danko na man fetur; ana iya amfani da shi don samar da chlorosulfonic acid, robar roba, da sauransu; ana iya amfani da shi don yin rini, ƙamshi, haɗa magunguna, chlorides daban-daban da masu hana tsatsa, da kuma tsaftace ƙarfe, pickling, electroplating, tanning, refining ko ƙera ƙarfe mai tauri. Ana amfani da iskar hydrogen chloride mai tsabta sosai a cikin haɓakar silicon epitaxial, polishing na tururi, gettering, etching da hanyoyin tsaftacewa a masana'antar lantarki.

Aikace-aikace:

①Kayan aiki:

Ana amfani da yawancin hydrogen chloride wajen samar da hydrochloric acid. Hakanan yana da mahimmanci a cikin sauran sauye-sauyen sinadarai na masana'antu.

②Semiconductor:

A cikin masana'antar semiconductor, ana amfani da shi don cire lu'ulu'u na semiconductor da kuma tsarkake silicon ta hanyar trichlorosilane (SiHCl3).

③Dakin gwaje-gwaje:

A cikin dakin gwaje-gwaje, nau'ikan iskar gas marasa ruwa suna da amfani musamman wajen samar da sinadarin Lewis mai sinadarin chloride, wanda dole ne ya bushe sosai domin wuraren Lewis su yi aiki.
