Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined.
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. There is no need for further mscs or risk reduction measures beyond those currently practiced. They are mainly produced as intermediate in the production of surfactantsfor use in detergent.
A desulfurization process is needed to reduce the sulfur content of some n-paraffins. LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they benzenr more slowly.
Each process generates LAB products with distinct features. The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs. Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant.

The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from kerosene benzenr raw material. The life-cycle analysis considered the emissions and resulting environmental and human exposures.
The report concludes that al,yl are no concerns for the environment or human health. This page was last edited on 30 Augustat 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.
Archived July 8,at the Wayback Machine. 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. Hydrotreated kerosene is a typical feedstock for high purity linear paraffins n-paraffinswhich are subsequently dehydrogenated to linear olefins:.
Consequently, most LAB plants built since then have utilized this process.
Other names LAB, linear alkyl benzene. Advances in Neutrino Technology. 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. 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 applications of LAB-derived detergents, a variety routes have been developed to jsds linear alkylbenzenes: Alternatively, ethylene can be oligomerized partially polymerized to produce linear alkenes.
