The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from kerosene as raw material. The report concludes that there are no concerns for the environment or human health.
They are mainly produced as intermediate in the production of surfactantsfor use in detergent. The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs. Archived from the original PDF aljyl Since the s, LABs have emerged as the dominant precursor of biodegradable detergents.
Linear alkylbenzene – Wikipedia
Advances in Neutrino Technology. Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined. Other names LAB, linear alkyl benzene. 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 Bezene Act Amendment.
Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12 -C 15C 12 benzeen 13 and C 10 -C 13for detergent use.
Lonear Wikipedia, the free encyclopedia. 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.
A desulfurization process is needed to reduce the sulfur content of some n-paraffins. Alternatively, ethylene pinear be oligomerized partially polymerized to produce linear alkenes.
The life-cycle analysis considered the emissions and resulting environmental and human exposures. LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they biodegrade more slowly. Each process generates LAB products with distinct features.
This page was last edited on 30 Augustat Consequently, most LAB plants built since then have utilized this process. Retrieved from benzeje https: The process eliminates catalyst neutralization and HF disposal. The UOP process for producing normal paraffin includes a kerosene prefractionation unit, a hydrotreating unit and a Molex unit. Ullmann’s Encyclopedia of Industrial Chemistry.
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. Linear alkylbenzene is sulfonated benzehe produce linear alkylbenzene sulfonate LASa biodegradable surfactant.
Given the large scale applications of Msdz detergents, a variety routes have been developed to produce linear alkylbenzenes: LAB has been subject to concern about its effect on the environment and human health.
