Pūhaumāota ferric

Toharite tote rino pūhaumāota nei tātai FeCl3, ko te pūhui o trivalent rino ki te waikawa pūmāota. Tenei taonga ko te pereti (rau) pango-parauri te tae, e ārohirohi me te kōpura i roto i te marama. He te taua rau o papura ranei matomato hue he konganuku umeraa.

Tenei pūhui whakaaturia hygroscopicity kaha, tika ki te rangi i raro i ngā āhuatanga noa tahuri ki te hydrate ona, te tātai o e FeCl3 • 6H2O. i kōwhai kōwhai-parauri te tae maitai wairewa i roto i te wai ranei enei tioata - i te otinga pāmahana dvadtsatigradusnoy i 100 karamu o te wai kei te tino memeha, 91.9 go o anhydrous tote pūhaumāota ferric.

ira whakakoero Ko 309 ° C. I roto i te ahumahi matū e whakaputaina ai, te tikanga i roto i te puka o te tote anhydrous rite te shestimolekulyarnogo tioata ranei. I roto i te ahumahi, kei te whakamahia te pūhaumāota rino mo te hanga o te terei parakore i roto i hokohoko i ngā coatings. I roto i taua hangarau katoa e tauhohe wahi ki te whai wāhitanga o te phenol cresol te Ethyl ranei hākawa, te mana nei i roto i te tauhohenga. Tikanga, Ko te ahua te pūhaumāota rino, me te evaporates tahi ki te kohu wai. A, no te rongoa i roto i te pani taiao taonga takawai. Ka taea te kite i tēnei āhuatanga noa i 100 ° C, te piki pāmahana atu me te pa tona tohu 317 ° C, rino pūhaumāota iii te tīmatanga ki te kohuatia, ka whakaeto, aru i te whāwehe. Tote, rite kei roto i tenei tikanga i te atamira haurehu waihā crystallizes tonu me te takoto i runga i te oko. I roto i tenei te hohenga ka kia pūmau e kore e horoia reira atu noa te whakamahi i waro tetrachloride, e condenses hoki i runga i nga taiepa o te oko.

Ka taea te whiwhi pūhaumāota Ferric i te akoranga o te whakamātau tika ohie. Ki te mahi i tenei, me mahi e koe i runga i te māota kotakota rino i roto i te āhua haurehu waihā. Ka rite ki te hua o te tauhohenga taua ka kia whiwhi tote ferric. Tenei rerekē i tēnei tauhohenga ko te tauhohenga i ai te taonga kaha he waikawa pūmāota.

Haunga tenei tikanga, kia rite pūhaumāota ferrous e te tauhohenga pitihāoratanga, e whai wāhi māota me te rino dichloride - 2FeCl2. More ngā i te wāhi o te tirohanga o te tono ko te tikanga mo te whakaputa trichloride rino i piti hāora o te whanariki waikura (IV).

Ko te puka kohu o trichloride rino kua he hanganga e he rawa rite ki taua o konumohe pūhaumāota i roto i te tauhohe o taua rāpoi tīmata tohatoha FeCl3 ina tae te pāmahana uara o 500 ° C.

Kei te whānui whakamahia tenei taonga rite te coagulant i roto i ngā hangarau maimoatanga wai. I roto i te ahumahi matū te whakamahia te reira rite te whākōkī i roto i te tauhohe o te ariā o ngā pūhui matū waro. Whānui e whakamahia ana i roto i te ahumahi pueru.

A, no te whakawera pūhaumāota rino, i muri i te taenga ki te pāmahana rewa me te pēhanga noa kōhauhau, decomposes reira i runga i ngā rāpoi ngota dichloride me te māota. Ko reira tino kaha Lewis waikawa trichloride, e taea o te whai wāhi i roto i tauhohe ki ētahi atu te pūhau. Ka rite ki te hua o taua tauhohe e whiwhi ngā tai waikawa tetrahlorozheleznoy, a na te para i te reira ki te rino waikura (III) ki 350 ° C whiwhi te oxychloride ferric.

Ko te tikanga, ko te tai o te pūhaumāota ferric ko nga āpiha oxidizing ngoikore, ahakoa i reira he okotahi. Hei tauira, ko reira tino ngāwari ki te oxidize parahi konganuku. Ka rite ki te hua o tenei tauhohenga e whiwhi wairewa te pūhau CuCl me CuCl2.

whakamahia rino trichloride te rite te kaihoko waikawa i roto i te hanga o te papa iahiko tā i roto i te reo irirangi me te zincographies. Ka rite ki te waiwhakaū he koha i roto i te ahumahi pueru. I roto i te tauine ahumahi trichloride rino e whakamahia i roto i te hangarau maimoatanga wai.

Ko te paitini tenei pūhui, whakahaere tukanga ha'iriiri. A ape i te rongo o kohua kohu pūhaumāota ferric ki te pūkahukahu.
