Khoom Description
Cov tshuaj nrog CAS tus lej 77 - 79 - 2 yog 3 - Sulfolene, tseem hu ua 2, 5 - Dihydrothiophene - 1, 1 - dioxide. Nws cov qauv molecular yog C₄H₆O₂S, qhov hnyav molecular yog 118.15, thiab EINECS tus lej yog 201 - 059 - 7.
Hais txog cov khoom ntawm lub cev, 3 - Sulfolen feem ntau tshwm raws li cov khoom siv dawb crystalline, tab sis nws kuj tseem tuaj yeem muaj xim xws li daj rau txiv kab ntxwv lossis xim av. Nws melting point yog 65 - 66 degree (lit.), lub boiling point yog kwv yees li 190.71 degree, qhov ceev yog 1.3 g / cm³, lub refractive index yog kwv yees li 1.4765, thiab lub flash point yog ntau tshaj 230 degree F. Nws tuaj yeem yaj hauv dej, ethanol, benzene thiab ether, nrog rau solubility ntawm 130 g / l hauv. dej.
Hais txog cov khoom siv tshuaj, 3 - Sulfolen tseem nyob ruaj khov nyob rau hauv qhov kub thiab txias. Txawm li cas los, nws decomposes thaum rhuab saum nws melting point. Nws yog flammable thiab incompatible nrog muaj zog oxidants.

Siv
3 - Sulfolene yog ib qhov chaw ntawm butadiene. Tshwj xeeb, nws yog lub hauv paus ntawm cis-butadiene hauv Diels - Alder cov tshuaj tiv thaiv, ua rau kev tsim kho ntawm ntau yam cyclic tebchaw hauv cov organic synthesis.
3 - Sulfolene ua los ntawm sulfur dioxide. Nws yog ib qho yooj yim ntawm sulfur dioxide thiab tuaj yeem siv los ua ib qho reagent hauv qee qhov kev xav uas xav tau kev qhia txog sulfur dioxide.
3 - Sulfolen muaj cov ntawv thov hauv kev lag luam petrochemical. Nws tuaj yeem siv los ua cov kuab tshuaj hauv qhov kev lag luam no kom rho tawm cov tshuaj tsw qab los ntawm cov dej hydrocarbon.
