Ingcaciso yeMveliso

I-Sulfolane ayinombala kwaye ayinancasa kubushushu begumbi, inyibilikiswe kwi-27.8℃. Iimveliso ezininzi zemizi-mveliso azinambala kwaye zilulwelo olumthubi olukhanyayo. I-Sulfolane ineempawu zokunyibilika eziphezulu kunye nokukhetha. I-Sulfolane inyibilikiswa emanzini ngomlinganiselo ongaqhelekanga, inyibilikiswa kwi-aromatics kunye notywala ngokulula, kodwa inyibilikiswa kwi-paraffin kunye ne-olefin hydrcarbon encinci. I-Sulfolane inozinzo oluphezulu kunye ne-asidi eshushu kunye ne-alkali. Isabela kwi-asidi, i-alkali, i-sulfur, utywala kubushushu begumbi, ikwabola kwaye ipolimerize. Xa ubushushu bungaphezulu kwe-240℃, i-sulfolane iyabola i-SO2. I-Sulfolane ineempawu zeekhemikhali ezizinzileyo, ayizukubonakala ngathi yi-polyreaction kunye nokubola phantsi kwemeko eqhelekileyo xa kukho i-asidi kunye ne-alkali.

Ipropati yokhuseleko lwe-sulfolane

Ezi mveliso zizinto ezinetyhefu encinci. Ityhefu engena emlonyeni wempuku enkulu yi:LD50>1900mg/kg. Ngokwe-International Ocean Shiping Dangerous Cargo Regulation, iSulfolane ayisiyonto iyingozi kwaye akukho ngcoliseko elwandle, ngoko ke ingathuthwa njengempahla eqhelekileyo.
