What does linear alkylbenzene sulfonate do?

Linear alkylbenzene sulfonate (LAS), the world’s largest-volume synthetic surfactant, which includes the various salts of sulfonated alkylbenzenes, is widely used in household detergents as well as in numerous industrial applications. The LABSA market is driven by the markets for LAS, primarily household detergents.

Is alkylbenzene sulfonate a detergent?

By sulfonation, alkylbenzene sulfonate is produced; marketed in powder and liquid form, it has excellent detergent and cleaning properties and produces high foam.

How is linear alkylbenzene sulfonate made?

Linear alkylbenzene sulfonates (LAS) are prepared industrially by the sulfonation of linear alkylbenzenes (LABs), which can themselves be prepared in several ways. The purified dodecylbenzenes (and related derivatives) are then sulfonated with sulfur trioxide to give the sulfonic acid.

What type of surfactant is LABSA?

anionic surfactant
Description. LABSA is an anionic surfactant, whose molecules are characterized by a hydrophilic and a hydrophobic group. This nonvolatile chemical compound is synthesized through the process of sulfonation.

Is linear alkylbenzene sulfonate toxic?

Linear alkylbenzene sulfonate (LAS) is a common organic pollutant in freshwater environments. Studies have shown that the toxicity of LAS to aquatic plants is directly related to the LAS concentration and depends on the plant species.

What is linear sulfonate?

Linear alkyl sulfonate (LAS) is an anionic surfactant widely used in detergents and cleaners, both in industrial and household applications. The linear alkyl chain of the LAS makes the molecule more biodegradable than branched alkyl benzene sulfonates. LAS is found in waste water.

Is linear alkyl benzene hazardous?

No specific hazards are encountered under normal use condition. The product may cause slight irritation to eyes and skin after prolonged and repeated contact, this product has a low vapour pressure therefore it is not an inhalation hazard.

How is linear alkyl benzene made?

Linear alkylbenzenes have been produced commercially via the following routes: 1) Dehydrogenation of n-paraffins to internal olefins followed by alkylation with benzene using a hydrofluoric acid (HF) catalyst; 2) Dehydrogenation of n-paraffins to internal olefins followed by alkylation with benzene using a fixed-bed of …

Is linear alkylbenzene sulfonate hazardous?

Causes eye irritation and burns. Eye contact can result in blindness; exposure to mist leads to watering, irritation. Skin: Skin contact may result in severe burns, blistering and pain.

Is linear alkylbenzene sulfonate an organic compound?

Alkyl benzene sulfonate (ABS) is an organic chemical compound primarily used as a surfactant. Linear alkylbenzene sulfonate (LAS), a biodegradable surfactant, is manufactured from sulfonation of linear alkyl benzene.
