Potassium emanzini

Ipotaziyam emanzini compound ke singonicheskoy ifomu crystal ngaphandle umbala. Indawo yayo yokunyibilika ilingana 948 ° C, xa loxinano iziyobisi ezithile 1,805 g / cm3 (loxinano icwangcisiwe kwiqondo lobushushu eqhelekileyo-14 ° C). Ezi ziikristale kulula enyibilikayo isisombululo zolwelo yaye hygroscopicity eliphezulu. Ukongeza, potassium emanzini na hydrolyzed, enyibilikayo glycerol kunye ethanol. Xa yokuxoxisana nabo ngexesha reactions kwakhiwa dihydrates kunye topotecan emele ziikristale enemibala emihle, luphawulwa ixabiso H0obr, ngokulandelelanayo, yaye -984,5 -1880,0 kJ / Mol.

Le into Kulula kakhulu ukuba ukuvula umoya igcwala, ngaloo ndlela uyila K2S2O3, kwaye ayaphuma ngethuba yokutsha SO2. Ipotaziyam emanzini yalungiselelwa K2S ogama ifomula, K2CO3 zakudibana isalfure, ngoko kuyimfuneko ukubonelela kuvamile ngaphandle ukungena komoya. Kuyenzeka ukuba ufumane into kunye indlela zokunciphisa, icarbon omele K2SO4 ityuwa.

Ipotaziyam emanzini lisetyenziswa njengesakhi esibalulekileyo kwi emulsion kunye Ipeyinti kushishino photosensitive kunye nemifanekiso. In chemical lemveliso isicelo yawo ngokusekelwe akwaziyo ukwenza reagent ekuqhubeni esekungcoleni sulfides ezahlukeneyo zesinyithi. Sebenzisa kwi eyolukiweyo neemfele sikuko potassium emanzini Ukuqukwa indlela yonyango yokuqala ngesikhumba.

Xa hydrosulfide okanye polysulfide impahla KHS wasetyenziswa kwiteknoloji sulfiding aluminium Ferro, uphose intsimbi nensimbi. Isetyenziswa ngokubanzi ekwenziweni imithi ukuba unyango ukuphazamiseka ezahlukeneyo ulusu. Agricultural isabelo potassium emanzini - ukusetyenziswa zinambuzane.

Njengomgaqo, potassium emanzini zezi ndlela noko elula. Ukuze oku mixed ikalika ekhawulezayo isalfure kunye potassium carbonate. Lo mxube koko unyityilikiswa emanzini, wayipheka kangangeeyure eziliqela. Ngenxa yale nkqubo usenziwa potassium polysulfide. Emva koko, ukusuka isisombululo ngenxa ngokusebenzisa lokucoca isuswe kwenze calcium carbonate, kwaye nesisombululo ngumphunga kwakuyo ngaphambi kokuba afike ubunzima ethile 1.25-1.30. Ekugqibeleni, isisombululo kwaye admixed ngakumbi kunye imali encinci isalfure, shushu kwakhona, yaye emva okupholisa obegalelwe.

Ipotaziyam emanzini Ukwakheka kwenzeka nangokobungakanani, kodwa ukuba loo flow yokusabela kuyimfuneko ukunika ngumphunga olucothayo kakhulu NH3 umphunga kumbhobho apho pre-kugcwele ukuba potassium hayidroksayidi. Ngenxa yoko, basabela kufuneka wenziwe ukunika ngokuchanekileyo ezingenambala isisombululo ammonia kwaye kwenze emhlophe leyo potassium emanzini.

Le nkcazelo okubangelwa yayilixesha kunokuba elide kuyimfuneko ukumpompa ngaphandle nempompo ioli ekhethekileyo, kwaye ke calcined kwiqondo lobushushu ka 400-500 ° C. Ngokuqhelekileyo, emveni ukuba ziikristale ifunyenwe zaye ungacolwanga ne-nitrogen nyulu ityhubhu zeemvavanyo vacuo.

Oku kubangela haydrolisis potassium disulfide i ngumgubo umbala omthubi, ifomula wayo - K2S2. Le into Ubunzima molekyuli ngu 142,327 amu Xa amaqondo obushushu 477 ° C dayisalfayidi uqala ukunyibilika kwaye 600 ° C ibola.

Ipotaziyam emanzini ke awasabela ngayo kunye izinto ezahlukeneyo. Umzekelo, phezu asabela kunye halides alkyl zaseprayimari afunyenwe sulfides dialkyl macala. Kwakhona izisombululo exube potassium emanzini kunye nezisombululo ezahlukeneyo (ingakumbi - hromokalievyh kunye umanyolo) alamu.

Ukulungiselela iinjongo loogqirha potassium emanzini ya ntumbuluko ophezulu. Kule shishino kokuba inikiwe ngamalahle ezahlukeneyo, apho olulungiswe umxube ukwimo ngokwayo, hayidroksayidi yayo nesalfure. Isebenze amalahle medical ihlasela emlilweni ezizodwa kubushushu ongekho ngaphantsi kwe 800 - 900 ° C. Ngoko ke ukususwa iikhompawundi isalfure okuxhaphaza of chlorine ion na zehydrochloric acid.
