LAB has been subject to concern about its effect on the environment and human health.
Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant. Ullmann’s Encyclopedia of Industrial Chemistry.
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: Retrieved from benzfne https: LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they biodegrade more slowly.
Since the s, LABs have emerged as the dominant precursor of biodegradable detergents. There is no need for further testing or risk reduction measures beyond those currently practiced.
Archived July 8,at the Wayback Machine. Linaer kerosene is a typical feedstock for high purity linear paraffins n-paraffinswhich are subsequently dehydrogenated to linear olefins:.
Views Read Edit View history. Retrieved 22 Dec 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 ilnear linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs.
Other names LAB, linear alkyl benzene. Important product characteristics include msdz bromine index, sulfonatability, amount of 2-phenyl isomers 2-phenylalkanethe tetralin content, amount of non-alkylbenzene components, and the linearity of the product. This page was last edited on 30 Augustat Each process generates LAB products with distinct features. From Wikipedia, the free encyclopedia. Archived from the original PDF on A desulfurization process is needed to reduce the sulfur content of some n-paraffins.
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. Hydrogen fluoride HF and aluminium chloride AlCl 3 are the two major catalysts for the alkylation of benzene with linear mono-olefins.
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.
Linear alkylbenzene – Wikipedia
Advances in Neutrino Technology. The life-cycle analysis considered the emissions and resulting environmental and human benzeje. 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. The report concludes that there are no concerns for the environment or human health.
Consequently, most LAB plants built since then have utilized this process. 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.
