Sulfolane.

NTP Research Concept: Sulfolane

Recently sulfolane has been detected in well water within the town of North Pole, Alaska. A plume was identified in groundwater, originating from a petroleum refinery, and the highest concentration measured in wells outside the refinery was 269 ppb as of January 2011. Due to the contamination, residents were being provided bottled water for use and additional wells were created outside the plum...

Crystal structure of cis-tetra­aqua­dichlorido­cobalt(II) sulfolane disolvate

In the title compound, [CoCl2(H2O)4]·2C4H8SO2, the Co(II) cation is located on the twofold rotation axis and is coordinated by four water mol-ecules and two adjacent chloride ligands in a slightly distorted octa-hedral coordination environment. The cisoid angles are in the range 83.27 (5)-99.66 (2)°. The three transoid angles deviate significantly from the ideal linear angle. The crystal packin...

Factors limiting sulfolane biodegradation in contaminated subarctic aquifer substrate

Sulfolane, a water-soluble organosulfur compound, is used industrially worldwide and is associated with one of the largest contaminated groundwater plumes in the state of Alaska. Despite being widely used, little is understood about the degradation of sulfolane in the environment, especially in cold regions. We conducted aerobic and anaerobic microcosm studies to assess the biological and abiot...

Conversion of fructose into 5-(hydroxymethyl)furfural in sulfolane.

Population growth has created an expanding gap between the supply and demand of both energy and chemicals. Nonrenewable fossil sources, such as coal, natural gas, and petroleum, are the source of nearly 86% of the world’s energy and 96% of its organic chemicals. Diminishing reserves of these sources, rising atmospheric CO2 levels, and socioeconomic concerns require a reduction of our dependence...
