Archived from the original PDF on The report concludes that there are no concerns for the environment or human health.
Nuclear Physics B – Proceedings Supplements. A desulfurization process is needed to reduce the sulfur content of some n-paraffins. Given the large scale applications of LAB-derived detergents, a variety routes have been developed to produce linear alkylbenzenes: Alternatively, ethylene can be oligomerized partially polymerized to produce linear alkenes.
The UOP process for producing mwds paraffin includes a kerosene prefractionation unit, a beenzene unit and a Molex unit. 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. 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.
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. Retrieved from ” https: LAB has been subject to concern about its effect on the environment and human health. For human health the scenarios for occupational exposure, consumer exposure and human exposure indirectly via benzdne environment have been examined and the possible risks identified.
The life-cycle analysis considered the emissions and resulting environmental and human exposures. The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from kerosene as raw material.
Linear alkylbenzene – Wikipedia
Linfar July 8,at the Wayback Machine. Advances in Neutrino Technology. From Wikipedia, the free encyclopedia. Hydrotreated kerosene is a typical feedstock for high purity linear paraffins n-paraffinswhich are subsequently dehydrogenated to linear olefins:.
Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant. 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.
Other names LAB, linear alkyl benzene. The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs.
Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined. Ullmann’s Encyclopedia of Industrial Chemistry. lineat
They are mainly produced as intermediate in the production of surfactantsfor use in detergent. Each process generates Lienar products with distinct features. There is no need for further testing or risk reduction measures beyond those currently practiced.
Hydrogen fluoride HF and aluminium chloride AlCl 3 are the two major catalysts for the alkylation of benzene with linear mono-olefins. Retrieved 22 Dec
