Preparation and Production of High Grade Sulfonic Acid

Sulfonic acid was prepared in laboratory by mixing Linear Alkyl Benzene , LAB ( which produced by the Arabic Chemicals for Detergents at Beige / Iraq) with fumic Sulfuric acid at 55 ? 60 C? for one minute residence time to know and to verify the practical conditions and requirements to be applied for mass production process flow sheet of high grade sulfonic acid production every pass which stimulates the construction of some fruitful plants locally. Samples of the prepared sulfonic acid were analyzed using Foot Print-IR Spectrometry showing that functional groups sites of the prepared compound are in coincidence with that of the standard Linear Alkyl benzene Sulfonic acid according to Colthup's tables for spectroscopic analytical data of standard compounds. The reaction is reliable, and almost of quantitative recovery within one minute residence time but it is highly exothermic, therefore a high efficient heat exchanger recommended to supply urgent cooling and appropriate materials selection should be considered for the construction of plant units, such as its resistance to corrosion as well as their homogeneity characteristics for thermal flow to avoid the production of side products which result in the production of low quality product, hence an auxiliary software should be constructed to control the process for high quality product insurance
