Sulfide potaziyamu

Potaziyamu sulfide pawiri ndi mtundu galasi singonicheskoy popanda mtundu. limatsogolera mfundo zake liri 948 ° C, pamene zenizeni mankhwala kachulukidwe 1,805 g / cm3 (kachulukidwe amamasulidwa pa kutentha muyezo 14 ° C). makhiristo ndi mosavuta sungunuka amadzimadzi njira ndi kukhala hygroscopicity mkulu. Komanso, sulfide potaziyamu ndi hydrolyzed, sungunuka glycerol ndi Mowa. Pamene zimavuta nawo pa zochita anapanga dihydrates ndi topotecan woimira timibulu colorless, yodziwika H0obr mtengo, motero, ndipo -984,5 -1880,0 KJ / mol.

thunthu zosavuta kutsegula mpweya makutidwe ndi okosijeni, potero kupanga K2S2O3, ndipo anamasulidwa pa kuyaka SO2. Potaziyamu sulfide linakonzedwa amene chilinganizo K2S, K2CO3 yatikhudza ndi sulfure, motero m'pofunika kupereka anachita kwa osaphatikiza inflow mpweya. N'zotheka kupeza zinthu ndi zimene kuchepetsa, mpweya kuchita mchere K2SO4.

Potaziyamu sulfide chimagwiritsidwa ntchito monga chida chigawo mu photosensitive emulsion ndi zokutira makampani ndi zithunzi. Mankhwala zotsimikizira ntchito zake zochokera luso zinthu reagent pogwira kulekana kwa sulfides zosiyanasiyana zitsulo. Ntchito nsalu ndi zikopa mafakitale tichipeza mu potaziyamu sulfide kulolerana wa njira chithandizo chachikulu cha chikopa.

Mu KHS hydrosulfide kapena polysulfide zinthu anamugwiritsa ntchito njira zamakono sulfiding kasakaniza wazitsulo ferro, kuponyedwa chitsulo ndi zitsulo. Ambiri ntchito mu kupanga medicaments zochizira matenda osiyanasiyana khungu. Ulimi sulfide ntchito potaziyamu - ntchito ngati mankhwala ophera tizilombo.

Monga ulamuliro, sulfide potaziyamu ndi mwachilungamo wosalira zambiri. Kuti ili losanganikirana laimu mofulumira ndi sulfure ndi carbonate potaziyamu. osakaniza Kenako kusungunuka m'madzi ndipo owiritsa kwa maola angapo. Chifukwa cha njirayi aumbike polysulfide potaziyamu. Ndiye, kuchokera njira chifukwa mu fyuluta kuchotsedwa precipitate kashiamu carbonate, ndi njira chamunthuyo yokha asanafike kulemera enieni 1.25-1.30. Pomaliza, njira Enanso admixed ndi pang'ono sulfure, usavutike, ndipo pambuyo yozizira udzathiridwa.

Potaziyamu sulfide mapangidwe amapezeka quantitatively, koma chifukwa otaya oterowo anachita ndi kofunika kupereka evaporation wochedwa wa NH3 nthunzi kudzera chubu amene ali chisanadze chodzaza ayenera potaziyamu hydroxide. Chifukwa cha zimenezi, zimene ayenera kuchitidwa bwino kupereka colorless amoniya njira ndi precipitate woyera umene uli potaziyamu sulfide.

Nkhani chifukwa inali nthawi m'malo yaitali n'kofunika kutulutsa kunja wapadera mpope mafuta, ndiyeno calcined pa kutentha 400-500 ° C. Kawirikawiri, pambuyo kuti timibulu analandira anali pulverized ndi oyera asafe machubu mayeso vacuo.

Chifukwa disulfide hydrolysis potaziyamu ndi ufa wa mtundu wachikasu, chilinganizo ake - K2S2. The maselo kulemera mankhwala ndi 142,327 amu Pa kutentha 477 ° C disulphide akuyamba kusungunula ndi pa 600 ° C izo linawola.

Potaziyamu sulfide ndi anachitira ndi zinthu zosiyanasiyana. Mwachitsanzo, pa anachita ndi halides alkyl chachikulu akamagwira sulfides symmetrical dialkyl. Komanso njira wosanganiza cha sulfide potaziyamu ndi njira zosiyanasiyana (makamaka - hromokalievyh ndi potashi) alum.

Mankhwala zolinga za sulfide potaziyamu wa chiyero mkulu. Ntchito imeneyi ndi kuperekedwa ndi makala osiyana, amene anakonza kuchokera chisakanizo cha thunthu yokha, hydroxide ake ndi sulfure. Mphamvu khala zachipatala amapezeka mu ng'anjo wapadera pa kutentha osati poyerekeza 800 - 900 ° C. Ndiye kuchotsa mankhwala sulfure ndi mwachinyengo wa ion chlorine ndi hydrochloric acid.
