TIB KAT SP is a formulation based on methane sulfonic acid and a phosphorous compound.
TIB KAT SP is an excellent catalyst providing high efficiency in esterification reactions.
In general terms the use of TIB KAT SP leads to products with significantly lighter colour values than using pure methane sulfonic acid, other sulfonic acids or sulfuric acid.

TIB KAT SP or methanesulphonic acid (in British English) is an organosulfuric, colorless liquid with the molecular formula CH3SO3H and structure H3C−S(=O)2−OH.
TIB KAT SP is the simplest of the alkylsulfonic acids (R−S(=O)2−OH). Salts and esters of methanesulfonic acid are known as mesylates (or methanesulfonates, as in ethyl methanesulfonate).
TIB KAT SP is hygroscopic in its concentrated form. Methanesulfonic acid can dissolve a wide range of metal salts, many of them in significantly higher concentrations than in hydrochloric acid (HCl) or sulfuric acid (H2SO4).

Uses
TIB KAT SP has been developed as an esterification catalyst in place of sulfuric acid for the synthesis of resins in paints and coatings.
One of the major advantages of methanesulfonic acid over sulfuric acid is that it is not an oxidizing species.
TIB KAT SP is a raw material for medicine and pesticide.
TIB KAT SP can also be used as dehydrating agent, curing accelerator for coating, treating agent for fiber, solvent, catalysis, and esterification as well as polymerization reaction.
TIB KAT SP can be used as solvent, alkylation, catalyst of esterification and polymerization, also used in medicine and electroplating industry.
TIB KAT SP can also be applied to oxidation.
Solutions of TIB KAT SP are used for the electroplating of tin and tin-lead solders.
TIB KAT SP is displacing the use of fluoroboric acid, which releases corrosive and volatile hydrogen fluoride.
TIB KAT SP is also a primary ingredient in rust and scale removers.
TIB KAT SP is used to clean off surface rust from ceramic, tiles and porcelain which are usually susceptible to acid attack.
Biological Activity
TIB KAT SP is involved in the biosynthesis of thyroid hormones T3 and T4.
TIB KAT SP catalyzes the oxidation of the inorganic iodide and coupling of iodinated tyrosine to produce thyroxine and triiodothyronine.
Mutation in the gene increases the risk of susceptibility to autoimmune thyroiditis in patients with allergic rhinitis and asthma.
Genetic deficiency of TIB KAT SP is associated with the development of congenital hypothyroidism.
Preparation
TIB KAT SP is produced predominantly by oxidizing methylthiol or dimethyl disulfide using nitric acid, hydrogen peroxide, chlorine or by employing electrochemical processes.
