Sulphur dioxide

Isalfure oxide (IV) unegama, naye wasebenzisa ngokusemthethweni kwinzululwazi chemical - sulphur dioxide, ukongeza, le nto ukwabizwa ngokuba sulphur dioxide okanye sulphur dioxide. Isalfure oxide (IV) phantsi kweemeko eziqhelekileyo - legesi ngokuba kungekho umbala, kunye livumba abayinqobo ntle, nto leyo sifunda linjengevumba umdlalo ngexesha ucinezelo.

Irhasi lwepetroliyam ngokwandisa uxinzelelo, iqondo lobushushu ukuze ayahlukanga ukusuka kwigumbi eziqhelekileyo. Le into enyibilikayo emanzini ukunika kabi acid ezingazinzanga. The degree of ukunyibilika wamanzi sulphur dioxide kubushushu 20 C 11,5 iigrem arhente 100 grams yamanzi nganye. Okubangel 'umdla kukuba, xa ubushushu, inqanaba ukunyibilika i-compound kunciphisa. Ngaphandle kwamanzi, sulphur dioxide enyibilikayo ethanol kunye sulphuric acid. Kwindalo, sulphur dioxide, ogama ifomyula SO2, yenye izinto ekulelona igesi mlilo.

Ukuveliswa industrial kwe-sulphur dioxide ngokusekelwe ukutshisa ngqo sulphur kwakhona eziqulunqwe zokudubula i sulfides igesi, ingakumbi ezifana pyrite.

Sulphur dioxide ifunyenwe kunye neendlela elebhu. Ngokuba lo yokusabela lwenziwa kwi kwimiphumo sulfites asidi olomeleleyo. Njengoko izinto ezingundoqo ezisetyenzisiweyo Iilabhoratri kunye hydrosulfites. Loo yokusabela okunene uphiwa ngaye lenxaki: Na2SO3 + H2SO4 → Na2SO4 + H2SO3. Isiphumo indlela njengoko kubonakala ukusuka lenxaki, a kabi acid, leyo ngenxa kozinzo yayo nangoko abole ukuya sulphur dioxide kunye namanzi.

izinto ngaphantsi asetyenziselwa indlela apho nempembelelo iintsimbi ngaphantsi esebenzayo kunye sulphuric acid yaze yangxenga ifuthe lomanyano, apho indlela kufuneka uqhubeke ngokushushubeza isisombululo yokusebenza.

Iipropati chemical enkulu ezi sulphur dioxide.

Sulphur dioxide ifunxwe kuluhlu yelanga spectrum. It zicalulwa njenge i oxide asidi. Njengoko sele kuchaziwe, sulphur dioxide enyibilikayo emanzini ikhemikali reaction ingathityazwa.

Xa kungeniswa werhasi ibe indlela ngealkali wavelisa sulfites ngokubanzi, xa isenza reactivity le gesi, kufuneka oko kakhulu phezulu. Ngexesha reactions ezininzi eziqhele wabonakalaliswa ukunciphisa iimpawu iziyobisi, kwaye inqanaba sulphur igcwala ngexesha reaction, iba ngaphezulu.

Iipropati igcwala of kubonisa sulphur dioxide ngexesha reactions abahamba reductants olomeleleyo. Umzekelo, kwicandelo lezoshishino nemveliso ngayo sulphur indlela esetyenziswayo babenobuzwe kwi yayo oxide nokubuyiselwa carbon (II).

Isalfure oxide (IV) kushishino yemichiza ye ubukhulu becala kusetyenziswa ukuvelisa sulphuric acid. Ngokubanzi, isicelo yayo ibanzi kakhulu kwaye antsonkothileyo. Into yokuba sulphur dioxide yityhefu. Ngu inhalation Ungafumana iimpawu etheni na umqala obuhlungu, impumlo esihambisayo, ukhohlokhohlo. umonakalo sulphur dioxide Inhalation kuzisa i ngakumbi kunokuba kwakunjalo ngaphezu xi ukwimo. Xa kungomlinganiselo aphezulu lunokwenzeka neziphumo ezimandundu, ukuya ukutsarhwa, iingxaki zokuthetha kunye nokudumba nezengekho miphungeni.

Isalfure oxide (IV) esetyenziswa yokudla, ngokukodwa ke ekhoyo kweziselo slaboalkogolnyh njenge ukubola. Xa noshishino lwempahla eyolukiweyo kwawo isetyenziswa njengento usemthethweni lithetha ukuba mhlophe ezahlukeneyo izinto abangakwaziyo eyome iikhompawundi chlorine.

Kwiilebhu mveliso kunye nezemfundo sulphur oxide (IV) isebenza kuphela neemfanelo, kodwa kule meko kufuneka kukhunjulwe ukuba irhasi iqulethe ukungcola zamanzi kunye SO3, leyo mogtst kuchaphazela enyulu, indlela echanekileyo indlela phambi dust. Ngoko ke, kule meko yalerhasi lingadlulanga edlula lokucoca equlathe kanzulu H2SO4, njalo ngesitya evaliweyo.

Ngenxa yokuba izenzo olubanzi dioxide ukusetyenziswa sulphur njengenye izinto ezinkulu ukungcolisa umoya. ezikhutshwayo iyingozi ezibangelwa ukutshiswa amandla ethu njengesiqhelo - amalahle, igesi yendalo kunye namafutha. Njengoko umthetho, uninzi neziphumo ezibi ngayo imvula, ngenxa yokuba emvula - imveliso isiphelo ekhoyo ifomu zetoti.

Okwangoku, ukufumaneka liphezulu le gesi ibhiyozelwa kumntla ikhweyitha, ingakumbi eUnited States, Ukraine, Western Europe kunye kwimimandla esentshona Russia.
