- EXAMPLE 1 Preparation of a methanesulfonic acid gel
- a gel containing 10% by weight of methanesulfonic acid is prepared by successively adding, with stirring, water, methanesulfonic acid, the surfactant and the gelling agent, in the following proportions:
- the gel obtained has a clear, non-spinning appearance. Viscosity is measured on a Brookfield DV II + instrument. All measurements are performed at room temperature. A viscosity of 240 cP at 10 revolutions per minute and 230 cP at 30 rpm is thus measured.
- the gel obtained is stable, without observation of phase separation separation after 2 months at 40 ° C.
- the descaling power is determined by applying the following protocol:
- the plate is dried in an oven at 110 ° C. for at least 1 hour;
- the plate is rinsed with running water by rubbing with a brush;
- the plate is dried at 110 ° C. for at least 1 hour and then placed in the desiccator to cool without moisture;
- the descaling power of methanesulfonic acid is greater than the descaling power of phosphoric acid, formulated as a gel at 10% by weight.
- the methanesulfonic acid is more effective, especially when used in gel form, as phosphoric acid for descaling operations.
- biodegradability of methanesulfonic acid which makes it a replacement product of choice for phosphoric acid for cleaning operations, including descaling, more particularly when formulated in the form of gel.
