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. 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.

LAB has been subject to concern about its effect on ljnear environment and human health.

A desulfurization process is needed to reduce the sulfur content of some n-paraffins. Since the s, LABs have emerged as the dominant precursor of biodegradable detergents.

Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12 -C 15C 12 linera 13 and C 10 -C 13for detergent use. Consequently, most LAB plants built since then have utilized this process. LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they biodegrade more slowly.


Ullmann’s Encyclopedia of Industrial Chemistry. Given the large scale applications of LAB-derived detergents, a variety routes have been developed to smds linear alkylbenzenes: Retrieved 22 Dec There is no need for further testing or risk reduction measures beyond those currently practiced. Archived July 8,at the Wayback Machine.

Alternatively, ethylene can be oligomerized partially polymerized to produce linear slkyl. Retrieved from ” https: The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs. The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from kerosene as raw material.

Linear alkylbenzene – Wikipedia

The UOP process for producing normal paraffin includes a kerosene prefractionation unit, a hydrotreating unit and a Molex unit. Hydrogen fluoride HF and aluminium chloride AlCl 3 are the two major catalysts for the alkylation of benzene with linear mono-olefins. Advances in Neutrino Technology. Each process generates LAB products with distinct features. The process eliminates catalyst neutralization and HF disposal.


Archived from the original PDF on They are mainly produced as intermediate in the production of surfactantsfor use in detergent. Nuclear Physics B – Proceedings Supplements. This page was last edited on 30 Augustat Other names LAB, linear alkyl benzene.

Linear alkylbenzene

From Wikipedia, the free encyclopedia. The HF-based process is commercially dominant; however, the risk of releasing HF a poisonous substance into the environment became a concern linera after the Clean Air Act Amendment. The life-cycle analysis considered the emissions and resulting environmental and human exposures. Hydrotreated kerosene is a typical feedstock for high purity linear paraffins lineqrwhich are subsequently dehydrogenated to linear olefins:. Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined.

Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant. Views Read Edit View history. The report concludes that there are no concerns for the environment or human health.
