In general, Sulfolane is unreactive with chemicals such as acids, mercaptans and diolefins, and will not polymerise or decompose under ordinary conditions in the presence of acids or bases.
• No reaction was observed between Sulfolane and potassium carbonate, sodium acetate, and 25% aqueous sodium hydroxide during 5 hours at reflux temperatures
• No reaction occurs under reflux between Sulfolane and copper or iron strips.
• Sulfolane is resistant to reduction by metallic zinc and acetic or hydrochloric acid.
• Reaction of the Grignard reagent ethyl magnesium bromide with the alpha-carbon hydrogen atoms of Sulfolane yields the magnesium bromide derivative and ethane; this derivative will react with bromine, iodine and chlorine to give 2- halosulfolane.
• The chlorination of Sulfolane with chlorine in carbon tetrachloride results in the formation of 3- chloro-,3,4-dichloroand 3,3,4- trichlorosulfolane. Sulphuryl chloride can also be used to chlorinate Sulfolane to produce 3- chlorosulfolane.
• Bromination of Sulfolane with bromine chloride in refluxing carbon tetrachloride under irradiation gives 2- bromosulfolane which reacts further to produce cis-2,5- dibromosulfolane.
• Sulfolane can undergo cleavage and dimerisation reactions; reductive cleavage by an alkali metal yields a butane sulphinate salt and up to 5-6% yields of a dimeric bis(1,8- octanedisulphinate salt).
• When Sulfolane is mixed with benzene and introduced slowly into a glass reactor at 400- 500°C, it is pyrolysed to produce mainly ethylene but also saturated hydrocarbons, hydrogen and sulphur dioxide.
• Sulfolane forms a 1:1 complex with boron trifluoride but no stable solid complex with phosphorus pentafluoride.
• Sulfolane also interacts with cellulose.
