Abstract
A process for manufacturing of an alkanesulfonic acid, and an alkanesulfonic acid manufactured by the process. Aspects of the process may involve manufacturing an alkanesulfonic acid by reaction of an initiator composition with an alkane and sulfur trioxide by preparing an initiator composition by reacting aqueous hydrogen peroxide with alkanesulfonic acid and/or H2SO4; and reacting the initiator composition with sulfur trioxide and alkane to form an alkanesulfonic acid, wherein an alkane with a purity of at least 98.0 mol-% is used.
Claims19
A process for manufacturing a methanesulfonic acid, the process comprising:
- preparing an initiator composition comprising reacting aqueous hydrogen peroxide with alkanesulfonic acid and/or H2SO4;
- reacting the initiator composition with sulfur trioxide and methane to form methanesulfonic acid,
- wherein the methane in the step of reacting the initiator composition has a purity of at least 98.0 mol-%, and
- wherein the methane has a maximum content of hydrocarbons of 500 ppm.
