Linear alkylbenzene

The process eliminates catalyst neutralization and HF bfnzene. By using this site, you agree to the Terms of Use and Privacy Policy. From Wikipedia, the free encyclopedia. They are mainly produced as intermediate in the production of surfactantsfor use in detergent.

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

Linear alkylbenzene – Wikipedia

Other names LAB, linear alkyl benzene. Retrieved from ” https: The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs.

The report meds that there are no concerns for the environment or human health. Advances in Neutrino Technology. The life-cycle analysis considered the emissions and resulting environmental and human exposures.


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. Consequently, most LAB plants built since then have utilized this process.


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.

Alternatively, ethylene can be oligomerized partially polymerized to produce linear alkenes. Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined. Nuclear Physics B – Proceedings Supplements. Each process generates LAB products with distinct features. Archived July 8,at the Wayback Machine.

Given the large scale applications of LAB-derived detergents, a variety routes have been developed to produce linear alkylbenzenes: 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.

Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant. The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from kerosene as raw material.


Archived from the original PDF on There is no need for further lakyl or risk reduction measures beyond those currently practiced. Views Read Edit View history.

This page was last edited on 30 Augustat A desulfurization process is needed to reduce the sulfur content of some n-paraffins.

Ullmann’s Encyclopedia of Industrial Chemistry.

LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they msdx more slowly. Hydrotreated kerosene is a typical feedstock for high purity linear paraffins n-paraffinswhich are subsequently dehydrogenated to linear olefins:. The UOP process for producing normal paraffin includes a kerosene prefractionation unit, a hydrotreating unit and a Molex unit.

The HF-based process is commercially dominant; however, the risk of releasing HF mdds poisonous substance into the environment became a concern particularly after the Clean Air Act Amendment.

Since the s, LABs have emerged as the dominant precursor of biodegradable detergents. Retrieved 22 Dec
