What is alkylbenzene sulfonate used for?
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.
Is Las toxic?
Degradation products of LAS are less toxic than the parent compound (46), and the toxicity of LAS might thus have been slightly underestimated in these experiments.
Is sodium c10 16 Alkylbenzenesulfonate toxic?
Based on the data available, the chemicals in this group may be toxic by inhalation.
How do you make alkylbenzene?
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 sodium lauryl benzene sulfonate?
Sodium dodecylbenzene sulfonate is a yellow oil, which can form a hexagonal or rhombic strong flake-like crystal. It has micro toxicity and has been recognized by the international security organization as a safe chemical raw material. Sodium dodecylbenzene sulfonate can be used to clean fruit and tableware.
What is LAS in detergent?
Linear Alkylbenzene Sulfonate (LAS) Description. LAS is the primary cleaning agent used in many laundry detergents. and cleaners at concentrations up to 25 percent in consumer products, somewhat higher in industrial/commercial products.
What is ABS in detergent?
Alkyl benzene sulfonate (ABS) refers to a family of branched chain organic chemical compounds that were used as detergents. They are regarded as “hard” detergents due to their resistance to biological degradation.
Is LAB a surfactant?
They are mainly produced as intermediate in the production of surfactants, for use in detergent….Linear alkylbenzene.

What are the possible side reactions of alkybenzene?
The well-known side reactions are the formation of sulfone (usually considered as an inert by-product), LAS anhydride and sulfuric acid. A good quality product typically contains; alkybenzene sulfonic acid, sulfuric acid and
How do you make linear alkylbenzene sulfonates?
Linear alkylbenzene sulfonates. Linear alkylbenzene sulfonates (LAS) are prepared industrially by the sulfonation of linear alkylbenzenes (LABs), which can themselves be prepared in several ways. In the most common route benzene is alkylated by long chain monoalkenes (e.g. dodecene) using hydrogen fluoride as a catalyst.
What are alkylbenzene sulfonates?
Alkylbenzene sulfonates. Alkylbenzene sulfonates are a class of anionic surfactants, consisting of a hydrophilic sulfonate head-group and a hydrophobic alkylbenzene tail-group.
Can linear alkylbenzene sulfonic acid be produced at high pressure?
Conclusions and Recommendations In this research, the production of linear alkylbenzene sulfonic acid (LAS) at high pressure in a supercritical carbon dioxide medium was investigated.
