Konurehu sulfide

Konurehu sulfide pūhui ko te puka karaihe singonicheskoy kahore tae. Ko tōna ira whakakoero ōrite 948 ° C, ka te tauwhāiti taonga kiato 1,805 g / cm3 (whakaturia te kiato te i te pāmahana paerewa 14 ° C). He ngāwari wairewa i roto i te wairewa nga tioata me te whai i te hygroscopicity tiketike. I tua atu, kua hydrolyzed konurehu pūngāwhā, wairewa i roto i te nonireka me te waihā ewaro. A, no te pāhekoheko ki a ratou i roto i te tauhohe i hanga dihydrates me topotecan e tohu tioata te huitahi, āhuatanga uara H0obr, aua, a -984.5 -1880.0 kJ / mol.

Ko te tino ngāwari ki te whakatuwhera i te hau piti hāora, reira hanga K2S2O3 te rawa, me te tukua i roto i parariraa SO2. i rite pāhare pāporo sulfide nei tātai K2S, K2CO3 te tauhohe i ki whanariki, ko te kupu te mea e tika ana ki te whakarato i tauhohe mō te hāunga whiwhinga o te rangi. He taea te reira ki te whiwhi i te taonga, me te i te tauhohenga whakaiti, waro mahi i runga i K2SO4 tote.

Kei te whānui whakamahia konurehu sulfide hei wähanga faufaa i roto i te whakaehunga me coatings ahumahi photosensitive me ngā whakaahua. I roto i te matū hokohoko tona tono i runga i te kaha ki te mahi kaiwhakahohe i mau ana i roto i te wehenga o ngā sulfides whakarewa. Whakamahi i roto i te pueru, me te hiako ahumahi ngā i roto i te pāhare pāporo sulfide whakaurunga o nga tikanga mo te maimoatanga tuatahi hiako o.

I roto i te whakamahia he hydrosulfide polysulfide ranei rauemi KHS i roto i hangarau sulfiding alloys ferro, maka rino, me te maitai. Kei te whānui whakamahia te reira i roto i te hanga o medicaments mo te maimoatanga o ngā disorders kiri. Agricultural sulfide taumahi pāhare pāporo - te whakamahi rite te paihana.

Ka rite ki te tikanga, konurehu sulfide he ara tika ohie. Ki tenei i konatunatua kotakota tere ki whanariki, me te konurehu pākawa waro. I te rewa tenei ranunga i roto i te wai, me te kohua mo te hāora. Ka rite ki te hua o tenei tikanga i hanga te konurehu polysulfide. Na, i te otinga hua i roto i te tātari nekehia hohenga konupūmā pākawa waro, a mimiti te otinga ki ano i mua i te taenga o te taimaha o 1.25-1.30 motuhake. I te pae hopea, i atu admixed te otinga ki te nui iti o te whanariki, kua oti te tahu ano, a i muri i te meangiti kua ringihia.

puta te ine nui pāhare pāporo sulfide hanganga, engari te mea e tika ana mo te taua rere tauhohenga ki te whakarato i te whakaetonga rawa puhoi o NH3 kohu i roto i te ngongo i te mea i mua ka ki-kia konurehu waihā. Ka rite ki te hua, kia kawea te tauhohenga i hoatu tika taekore otinga haukini me te hohenga ka ma i te mea pāhare pāporo sulfide.

Ko te rauemi hua ko te mea tika, he wa pai roa ki te papu i roto i te papu hinu motuhake, a ka ka calcined i te pāmahana o te 400-500 ° C. Ko te tikanga, i muri i heke nga tioata whiwhi i me te hauota purea ana i roto ipuipu i vacuo.

Ko te hua paparetanga konurehu disulfide ko te puehu o te tae kōwhai, tona tātai - K2S2. Ko te taonga taimaha rāpoi he 142,327 amu I te pāmahana o 477 ° C disulphide tīmata ki te ngohe me te i 600 ° C decomposes reira.

tali pāhare pāporo sulfide te ki ngā matū. Hei tauira, i runga i te tauhohenga ki halides alkyl tuatahi e whiwhi e sulfides dialkyl hangarite. Hoki rongoā whakauru o te pāhare pāporo sulfide ki ngā rongoā (rawa - hromokalievyh me te hopi) waikonumohe.

Hoki ngā take hauora te sulfide pāhare pāporo o te viivii tiketike. I roto i tenei ahumahi tukua atu e waro rerekē, e kua rite i te ranunga o te taonga iho, tona waihā me te whanariki. puta Whakaoho waro hauora i roto i oumu motuhake i te pāmahana o te kore i raro i 800 - 900 ° C. Na te tango o pūhui whanariki me te papamuka e o te māota katote ko te waikawa pūmāota.
