Chlorosulfonic acid is a strong acid that is synthesized on an industrial scale by reacting sulfur trioxide and dry hydrogen chloride gas in an equimolar ratio. It can act as a sulfonating, dehydrating, oxidizing and chlorinating agent. It is reported to be a better electrophilic olefin cyclization agent in comparison to other sulfonic acids. Its infrared spectra in the solid, liquid and gaseous state have been recorded in the region 4000-400cm-1.
Melamine also enters the fabrication of melamine poly-sulfonate used as superplasticizer for making high-resistance concrete. Sulfonated melamine formaldehyde (SMF) is a polymer used as cement admixture to reduce the water content in concrete while increasing the fluidity and the workability of the mix during its handling and pouring. It results in concrete with a lower porosity and a higher mechanical strength, exhibiting an improved resistance to aggressive environments and a longer lifetime.
