From Wikipedia, the free encyclopedia. Given the large scale applications of LAB-derived detergents, a variety routes have been developed to produce linear alkylbenzenes: The UOP process for producing normal paraffin includes a kerosene prefractionation unit, a hydrotreating unit and a Molex unit.
LAB has been subject to concern about its effect on the environment and human health. A desulfurization process is needed to reduce the sulfur content of some n-paraffins. Nuclear Physics B – Proceedings Supplements.
Linear alkylbenzene – Wikipedia
Retrieved from ” https: Since the s, LABs have emerged as the dominant precursor of biodegradable detergents. Alternatively, ethylene can be oligomerized partially polymerized to produce linear alkenes.
LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they biodegrade more slowly. Consequently, most LAB plants built since then have utilized this process. They are mainly produced as intermediate in the production of surfactantsfor use in detergent.
Archived July 8,at the Wayback Machine. The process eliminates catalyst neutralization and HF disposal. Other names LAB, linear alkyl benzene.
Hydrotreated kerosene is a typical feedstock for high purity linear paraffins n-paraffinswhich are subsequently dehydrogenated to linear 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. Advances in Neutrino Technology. 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 is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant. This page was last edited on 30 Augustat 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.
Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined.
The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce bnezene LABs. There is no need for further testing or risk reduction measures beyond those currently practiced.
The life-cycle analysis considered the emissions and resulting environmental and human exposures. Archived from the original PDF on Each process generates LAB products with alky, features. Ullmann’s Encyclopedia of Industrial Chemistry. Hydrogen fluoride HF and aluminium chloride AlCl 3 are the two major catalysts for the alkylation of benzene with linear mono-olefins.
Retrieved 22 Dec 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.
