Consequently, most LAB plants built since then have utilized this process.
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. Each process generates LAB products with distinct features.
Archived July 8,ksds the Wayback Machine. 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 LAB has been subject to concern about its effect on the environment and human health. The report concludes that there are no concerns for the environment or human health.
Retrieved from ” https: The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from mwds as raw material. Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant. Advances in Neutrino Technology. A desulfurization process is needed to reduce the sulfur msdss of some n-paraffins.
Hydrogen fluoride HF and aluminium chloride AlCl 3 are the two major catalysts for the alkylation of benzene with linear mono-olefins. Other names LAB, linear alkyl benzene.
The process eliminates catalyst neutralization and HF disposal. From Wikipedia, the free encyclopedia.
Linear alkylbenzene – Wikipedia
Since the s, LABs have emerged as the dominant precursor of biodegradable detergents. 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.
Given the large scale applications of LAB-derived detergents, a variety routes have been linesr to produce linear alkylbenzenes: Ullmann’s Encyclopedia of Industrial Chemistry. The life-cycle analysis considered the emissions and resulting environmental and human exposures. There wlkyl 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.
Views Read Edit View history. Retrieved 22 Dec This page was last edited on 30 Augustat Alternatively, ethylene can be oligomerized partially polymerized to produce linear alkenes.
The UOP process for producing normal paraffin includes a kerosene prefractionation unit, a hydrotreating unit and a Molex unit. LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they biodegrade more slowly. The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs. 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.
They are mainly produced as intermediate in the production of surfactantsfor use in detergent.
