Definition Of Sulfonic Acid (LABSA)

LABSA (Linear Alkyl Benzene Sulphonic Acid) is produced by the sulphonation reaction of Alkyl Benzene with Sulphur trioxide (SO). Some other processes might desire the use of Oleum or Sulphuric acid. The final decision will depend on various factors which might include the availability of raw material, location of the plant, the size of the plant, operation mode of the plant, to mention a few. Nevertheless, considering major factors such as cost, availability, flexibility and safety, SO still remains the preferential reagent for the reaction which is as shown on the flow sheet.

Linear Alkyl Benzene Sulphonic Acid is one of the major active ingredients for the production of soaps and detergents. Importantly, it forms a greater percentage of raw materials for the production of liquid soaps. LABSA is an anionic surfactants with molecules characterized by a hydrophobic and a hydrophilic group. They are nonvolatile compounds produced by sulfonation. Linear alkylbenzenes (sometimes also known as LABs) are a family of organic compounds with the formula C6H5CnH2n+1.

They are mainly produced as intermediate in the production of surfactants, for use in detergent. Since the 1960s, LABs have emerged as the dominant precursor of biodegradable detergents. Linear Alkyl Benzene Sulfonic Acid is the largest-volume synthetic surfactant because of its relatively low cost, good performance, the fact that it can be dried to a stable powder, biodegradable and environment friendly. Alkyl benzene sulfonic acid is used as anionic surfactant in the formulation of many washing compounds.

This sulfonic acid is one of the cheapest surfactants in the washing industry and is the most important and most consumable substance in a powder formulation and pure liquids.

Sulfonic acid is the water-soluble, non-volatile and adsorbent and sulfonic acid used as emulsifiers, additives and lubricating oils .Sulfonic acid used as corrosion prevention and rust. The position of the alkyl benzene sulfonic acid as anionic surfactant is used in the formulation of many of the washing compounds. LABSA is an anionic surfactants with molecules characterized by a hydrophobic and a hydrophilic group. They are nonvolatile compounds produced by sulfonation.

LABSA are complex mixtures of homologues of different alkyl chain lengths (C10 to C13 or C14) and phenyl positional isomers of 2 to 5-phenyl in proportions dictated by the starting materials and reaction conditions.

Application of Sulfonic Acid (LABSA)

LABSA is widely used for producing various detergents and emulsifiers, such as washing powder, detergent of dishware, detergent of light or hard dirt, detergent for the textile industry, dyeing assistant, degreaser of plating and leather making industry, and the deinking agent of paper-making industry, etc.

Linear alkylbenzenes is sulfonated to produce linear alkylbenzene sulfonate (LAS), a biodegradable surfactant. LAS replaced branched dodecylbenzene sulfonates, which were phased out because they biodegrade more slowly.

sulfonic acid used in hair shampoo, bath shampoo, dish detergents and complex soap, laundry powder, dishware cleaner in daily chemical industrial Sulfonic acid is used in wetting and clearer , dyeing assistant in textile industry too .Sulfonic acid is the degrease agent in electroplate and leather industry, de-inking agent in paper industry.

Packing of Sulfonic Acid (LABSA)

Labsa packed in new or used drums, iso tank, Flexitanks, and bulk shipments. Each 20-foot container takes 80 drums.
