Since the s, LABs have emerged as the dominant precursor of biodegradable detergents.

Linear alkylbenzene

The HF-based process is commercially dominant; however, the risk of releasing HF a poisonous substance into the environment became a concern particularly after the Clean Air Act Amendment. Advances in Neutrino Technology. Each process generates LAB products with distinct features. Hydrogen fluoride HF and aluminium chloride AlCl 3 are the two major catalysts for the alkylation of benzene with linear mono-olefins.

For human health the scenarios for occupational exposure, consumer exposure and human exposure indirectly via the environment have been examined and the possible risks identified. Archived July 8,at the Wayback Machine. Nuclear Physics B – Proceedings Supplements.

The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from kerosene as raw material. Views Read Edit View history. From Wikipedia, the free encyclopedia. Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined.

Ullmann’s Encyclopedia of Industrial Chemistry.

Linear alkylbenzene – Wikipedia

Alternatively, ethylene can be oligomerized partially polymerized to produce linear alkenes. LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they biodegrade more slowly.

Archived from the original PDF on Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12 -C 15C 12 -C 13 and C 10 -C 13for detergent use. Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant.

The UOP process for producing normal paraffin includes a kerosene prefractionation unit, a hydrotreating unit and a Molex unit. Given the large scale applications of LAB-derived detergents, a variety routes have been developed to produce linear alkylbenzenes: A desulfurization process is needed to reduce the sulfur content of some n-paraffins.

Important product characteristics include the bromine index, sulfonatability, amount of 2-phenyl isomers 2-phenylalkanethe tetralin content, amount of non-alkylbenzene components, and the linearity of the product.

The life-cycle analysis considered the emissions and resulting environmental and human exposures. Retrieved 22 Dec Retrieved from ” https: Hydrotreated kerosene is a typical feedstock for high purity linear paraffins n-paraffinswhich are subsequently dehydrogenated to linear olefins:.

The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs. They are mainly produced as intermediate in the production of surfactantsfor use in detergent.

There is no need for further testing or risk reduction measures beyond those currently practiced. Consequently, most LAB plants built since then have utilized this process.

Other names LAB, linear alkyl benzene. The report concludes that there are no concerns for the environment or human health. The process eliminates catalyst neutralization and HF disposal.

This page was last edited on 30 Augustat LAB has been subject to concern about alky effect on the environment and human health.
