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. There is no need for further testing or risk reduction measures beyond those currently practiced. The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from kerosene as raw material.

Each process generates LAB products with distinct features. bejzene

The report concludes that there are no concerns for the environment or human health. LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they biodegrade more slowly. Archived from the original PDF on Given the large scale applications of LAB-derived detergents, a variety routes have been developed to produce linear alkylbenzenes: Views Read Edit View history.


Retrieved 22 Dec A desulfurization process is needed to reduce the sulfur content of some n-paraffins.

alkul The life-cycle analysis considered the emissions and resulting environmental and human exposures. Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant. Hydrotreated kerosene is a typical feedstock for high purity linear paraffins n-paraffinswhich are subsequently dehydrogenated to linear olefins:.

From Wikipedia, the free encyclopedia. For human health the scenarios for occupational exposure, consumer exposure and human exposure indirectly via the benzeen have been examined and the possible risks identified.

Advances in Neutrino Technology. 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.

Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined.

The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs. Archived July 8,at the Wayback Machine. Ullmann’s Encyclopedia of Industrial Chemistry. Hydrogen fluoride HF and aluminium chloride AlCl 3 are the two major catalysts for the alkylation of benzene with linear mono-olefins.

They are mainly produced as intermediate in the production of aklylfor use in detergent. LAB has been subject to concern about its effect on the environment and human health.

Linear alkylbenzene

Other names LAB, linear alkyl benzene. Consequently, most LAB plants built since then have utilized this process.

Nuclear Physics B – Proceedings Supplements. The process eliminates catalyst neutralization and HF disposal. Retrieved from ” https: Since the s, LABs have emerged as the dominant precursor of biodegradable detergents. This page was last edited on 30 Augustat 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. 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.
