I-Sulfuryl Fluoride (F2O2S)

Imingcele Yezobuchwepheshe

Isicelo:

I-Sulfuryl fluoride isetshenziswa kabanzi njengesibulala-zinambuzane esinesakhiwo esibulalayo ukuze silawule umuhlwa wokhuni olomile.

ingasetshenziswa futhi ukulawula amagundane, ibhungane eliyimpushana, amabhungane ewashi elibulalayo, amagxolo, nezimbungulu.

Iphakheji evamile:

I-Sulfuryl fluoride iyinhlanganisela ye-inorganic formula yayo yamakhemikhali i-SO2F2. Igesi elingenambala, elingenaphunga, elinobuthi ngaphansi kwezinga lokushisa elivamile nokucindezela, elincibilika kancane emanzini, elincibilika ku-ethanol, benzene, ne-carbon tetrachloride. Ayisebenzi ngamakhemikhali, ayiboli ezingeni lokushisa eliphezulu, izinzile ku-400°C, futhi ayisebenzi kakhulu. Uma ihlangana namanzi noma umhwamuko wamanzi, ikhiqiza ukushisa futhi ikhiphe igesi edlayo enobuthi. Uma kushisa kakhulu, ukucindezela kwangaphakathi kwesitsha kuzokwanda futhi kunengozi yokuqhekeka nokuqhuma. Ngoba i-sulfuryl fluoride inezici zokusabalaliswa okuqinile nokungeneka, isibulala-zinambuzane esibanzi, umthamo ophansi, izinsalela eziphansi, isivinini esisheshayo sokubulala izinambuzane, isikhathi esifushane sokungenisa umoya, ukusetshenziswa kalula ezingeni lokushisa eliphansi, alinawo umthelela ezingeni lokuhluma, kanye nobuthi obuphansi. Isetshenziswe kakhulu ezindaweni zokugcina izimpahla, imikhumbi yezimpahla, iziqukathi nezakhiwo, izindawo zokugcina amanzi, amadamu, ukulawula umuhlwa, kanye nezinambuzane ezihlala engadini kanye nezinambuzane eziphilayo ezibhoboza izihlahla. I-Sulfuryl fluoride iyasebenza kakhulu, futhi inemiphumela emihle yokulawula inqwaba yezinambuzane ezifana nebhungane elibomvu, ibhungane lamagxolo amnyama, ibhungane likagwayi, i-corn weevil, inundu kakolweni, ibhungane elide, i- mealworm, i-armyworm, i-mealy beetle, njll. umphumela we-insecticidal ungafinyelela ku-100% lapho umthamo ungama-20-60g/m3, futhi ukufuthwa kuvaliwe izinsuku ezingu-2-3. Ikakhulukazi esigabeni sokugcina semibungu yezinambuzane, isikhathi sokubulala izinambuzane sifushane kune-methyl bromide, umthamo uphansi kune-methyl bromide, futhi isikhathi sokuhlakazeka komoya siyashesha kune-methyl bromide. I-Sulfuryl fluoride nayo isetshenziswa njengama-reagents okuhlaziya, imithi, nodayi. I-Sulfuryl fluoride inezindawo zamakhemikhali ezizinzile futhi ingasetshenziswa ngokuphepha ukufutha izinto ezijwayelekile zasendlini. Izindlela zokuphepha zokulondoloza: Gcina endaweni yokugcina impahla epholile, eyomile, futhi enomoya omuhle. Gcina kude nomlilo nemithombo yokushisa. Gcina isitsha sivalwe ngokuqinile. Kufanele igcinwe ngokuhlukana nama-alkali namakhemikhali adliwayo futhi igweme ukugcinwa okuxubile. Indawo yokugcina kufanele ifakwe okokusebenza okuphuthumayo okuvuzayo.

Inzuzo:

① Ngaphezu kweminyaka eyishumi emakethe;

②ISO umenzi wesitifiketi;

③Ukulethwa okusheshayo;

④Umthombo wezinto ezingavuthiwe ozinzile;

⑤Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;

⑥Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;
