Ferric mankhwala enaake

Avereji ya chitsulo mankhwala enaake mchere amene chilinganizo FeCl3, ndi pawiri la trivalent chitsulo ndi hydrochloric acid. mankhwala ndi mbale (masamba) wakuda-bulauni mtundu, amene shimmer ndi kukulowa kuwala. Iwo ali masamba chomwecho wofiirira kapena zobiriwira hue ndi zachitsulo luster.

pawiri Izi akusonyeza amphamvu hygroscopicity, mwachindunji mpweya m'mikhalidwe yachibadwa inasanduka hydrate zace, chilinganizo chimene FeCl3 • 6H2O. timibulu awa anali chikasu kapena wachikasu-bulauni mtundu mwangwiro sungunuka m'madzi - pa njira kutentha dvadtsatigradusnoy mu magalamu 100 a madzi kwathunthu kotero, 91,9 ga anhydrous ferric mankhwala enaake mchere.

Limatsogolera mfundo ndi 309 ° C. Makampani mankhwala chifukwa amapangidwa, kawirikawiri mu mawonekedwe a mchere anhydrous kapena ngati shestimolekulyarnogo crystalline. Makampani, chitsulo mankhwala enaake ntchito yopanga polystyrene oyera zotsimikizira zokutira zosiyanasiyana. Mu njira zamakono zonsezi zimachitika chikuchitika ndi nawo phenol kapena cresol ethyl Ester, amene ankalamulira pa zotani. Childs, chitsulo mankhwala enaake ndi loopsali ndi ukuphwera pamodzi ndi nthunzi. Pamene kusungidwa mu chinyezi chafalikiradi chilengedwe mankhwala. zodabwitsazi zingaoneke ngakhale pa 100 ° C, kutentha ukuwonjezeka zina ndi kufika chizindikiro chake 317 ° C, chitsulo mankhwala enaake III wayamba wiritsani ndi asanduke nthunzi, kenako kuwonongeka. Salt, zakonzedwa m'njira imeneyi ku siteji gaseous yomweyo crystallizes ndipo anakaika pa chotengeracho. Mu ichi precipitate kotero khola kuti si yagwa ngakhale ntchito mpweya tetrachloride, amenenso kumaundanitsa pa makoma a chotengeracho.

mankhwala enaake Ferric akhoza zopezera mu njira ya kuyesera mwachilungamo wophweka. Kuti tichite zimenezi, muyenera kuchita pa chitsulo filings chlorine mu boma gaseous. Chifukwa cha zimenezi zingachitike adzakhala analandira ferric mchere. Izi isiyana anachita izi zimachitika imene mankhwala yogwira ndi hydrochloric acid.

Kuwonjezera njira imeneyi, mankhwala enaake akakhala akhoza kukhala okonzeka ndi makutidwe ndi okosijeni anachita, zimene zimaphatikizapo chlorine ndi chitsulo dichloride - 2FeCl2. More chidwi ku mawonedwe a ntchito ndi njira yopangira zitsulo trichloride ndi makutidwe ndi okosijeni wa okusayidi sulfure (IV).

The nthunzi mawonekedwe trichloride chitsulo ali ndi dongosolo kuti ndi zayamba yofanana ndi ya mankhwala enaake zotayidwa pa zimene mamolekyu otere FeCl3 Kugawilidwa kwanthaka limayamba pamene kutentha ukufika mfundo za 500 ° C.

mankhwala chimagwiritsidwa ntchito monga coagulant mu njira zamakono zosiyanasiyana madzi mankhwala. Makampani mankhwala agwiritsidwe ntchito ngati chothandizira mu zochita za kaphatikizidwe wa mankhwala organic. Chimagwiritsidwa ntchito makampani nsalu.

Pamene Kutentha chitsulo enaake, akafika limatsogolera kutentha ndi wabwinobwino mumlengalenga kuthamanga, izo linawola pa dichloride ndi chlorine mamolekyulu. Ndi mwachilungamo amphamvu Lewis asidi trichloride, waluso pa ntchito zosiyanasiyana ndi chlorides ena. Chifukwa cha maganizo amene analandira salt zosiyanasiyana tetrahlorozheleznoy asidi, ndi Kutentha ndi chitsulo okusayidi (III) kwa 350 ° C analandira ferric oxychloride.

Nthawi zambiri, kuphatikizapo ya mankhwala enaake ferric ali ofooka wothandizila oxidizing, ngakhale pali kuchotserapo. Mwachitsanzo, n'zosavuta kwambiri kuti oxidize mkuwa zachitsulo. Chifukwa cha linachepa analandira sungunuka chlorides CuCl ndi CuCl2.

Iron trichloride ntchito monga nthumwi etching mu kupanga matabwa kusindikizidwa dera mu wailesi ndi zincographies. Monga mordant ndi irreplaceable makampani nsalu. Mu mafakitale lonse chitsulo trichloride ntchito njira zamakono madzi mankhwala.

pawiri Izi ndi poizoni, facilitates njira zikuwononga. Pewani padzuwa la otentha nthunzi ferric mankhwala enaake mu mapapo.
