Other names LAB, linear alkyl benzene. The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from kerosene as raw material.
From Wikipedia, the free encyclopedia. The report concludes that there are no concerns for the environment or human health.
A desulfurization process is needed to reduce the sulfur content of some n-paraffins. LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they biodegrade more slowly. 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 aliyl the product.
The life-cycle analysis considered the emissions and resulting environmental and human exposures.
LAB has been subject to concern about its effect on the environment and human health. Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined.
The process eliminates catalyst neutralization and HF disposal. 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. Alternatively, ethylene can be oligomerized partially polymerized to produce linear alkenes.
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.
The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs. Archived July 8,at the Wayback Machine.
Linear alkylbenzene – Wikipedia
Hydrogen fluoride HF and aklyl chloride AlCl 3 are the two major catalysts for the alkylation of benzene with linear mono-olefins. Ullmann’s Encyclopedia of Industrial Chemistry. Advances in Neutrino Technology. Views Read Edit View history.
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.
Each process generates LAB products with distinct features. They are mainly produced as intermediate in the linnear of surfactantsfor use in detergent. Retrieved from ” https: Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant. Archived from the original PDF on There is no need for further testing or risk reduction measures beyond those currently practiced.

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.
