Incazelo Yomkhiqizo

I-Sulfolane ayinombala futhi ayinambitheki kahle ekushiseni kwegumbi, incibilike ku-27.8℃. Imikhiqizo eminingi yezimboni ayinambala futhi ayiphuzi. I-Sulfolane inamandla okuncibilika kakhulu kanye nokukhetha. I-Sulfolane incibilika emanzini ngesilinganiso esingahleliwe, incibilika futhi kuma-aromatic notshwala kalula, kodwa incibilika ku-paraffin kanye ne-olefin hydrcarbon kancane. I-Sulfolane inamandla aphezulu nge-asidi eshisayo kanye ne-alkali. Isabela nge-asidi, i-alkali, i-sulfur, utshwala ekushiseni kwegumbi, futhi iyabola futhi i-polymerize. Uma izinga lokushisa liphezulu kune-240℃, i-sulfolane izobola i-SO2. I-Sulfolane inamandla amakhemikhali azinzile, ngeke ibonakale i-polyreaction kanye nokubola ngaphansi kwesimo esivamile lapho kukhona i-asidi kanye ne-alkali.

Impahla yokuphepha ye-sulfolane

Le mikhiqizo iyinto enobuthi obuphansi. Ubuthi obungena emlonyeni wegundane elikhulu bungu:LD50>1900mg/kg. Ngokusho koMthethonqubo Wezokuthutha Impahla Eyingozi Yolwandle Lwamazwe Ngamazwe, iSulfolane ayiyona into eyingozi futhi akukho ukungcola olwandle, ngakho-ke ingathuthwa njengempahla evamile.
