Other names LAB, linear alkyl benzene. Archived July 8,at the Wayback Machine. Views Read Edit View history. A desulfurization process is needed to reduce the sulfur content of some n-paraffins. Retrieved msd Dec Nuclear Physics B – Proceedings Supplements.
The life-cycle analysis considered the emissions and resulting environmental and human exposures. From Wikipedia, the free encyclopedia. Retrieved from ” https: Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant.
Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined. Archived from the original PDF on The UOP process for producing normal paraffin includes a kerosene prefractionation unit, a hydrotreating unit and a Molex unit.
Linear alkylbenzene – Wikipedia
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. They are mainly produced as intermediate in the production of surfactantsfor use in detergent.
The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from kerosene as raw material. Ullmann’s Encyclopedia of Industrial Chemistry. Since the s, LABs have behzene as the dominant precursor of biodegradable detergents.
The report concludes that there are no concerns for the environment or human health.
Advances in Neutrino Technology. Each process generates LAB products with distinct features. This page was last edited on 30 Augustat 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. The benzeen eliminates catalyst neutralization and HF disposal. 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. Given the large scale linera of LAB-derived detergents, lineaar variety routes have been developed to produce linear alkylbenzenes: LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they biodegrade more slowly. Hydrotreated kerosene is a typical feedstock for high purity linear paraffins n-paraffinswhich are subsequently dehydrogenated to linear olefins:.
There is no need for further testing or risk reduction measures beyond those currently practiced. 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. Typically, n lies between 10 and 16, although linea supplied as a tighter cut, such as C 12 -C 15C 12 -C 13 and C 10 -C 13for detergent use. The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs.
