Abstract
Haloalkane sulfonic acids and salts thereof are provided. In embodiments, a haloalkane sulfonic acid or salt thereof comprises an alkyl group, at least one sulfonic acid group, and one or more halogens selected from Cl, Br, I, and F, the haloalkane sulfonic acid having a total number of carbon atoms of from 2 to 9, and wherein if at least one F atom is present, the haloalkane sulfonic acid comprises at least one other halogen selected from Cl, Br, and I. Methods of making and using the haloalkane sulfonic acids/salts are also provided.
Claims20
A single-step process for preparing a haloalkane sulfonic acid or salt thereof, the process comprising combining a haloalkene with oleum or 98% sulfuric acid under conditions to react H2SO4 with the carbon-carbon double-bond of the haloalkene to convert the haloalkene to a haloalkane sulfonic acid or salt thereof, wherein the haloalkane sulfonic acid comprises an alkyl group, at least one sulfonic acid group, and one or more halogens selected from Cl, Br, I, and F, the haloalkane sulfonic acid having a total number of carbon atoms of from 2 to 9, and wherein if at least one F atom is present, the haloalkane sulfonic acid comprises at least one other halogen selected from Cl, Br, and I.
