The UOP process for producing normal paraffin includes a kerosene prefractionation unit, a hydrotreating unit and a Molex unit. The production of n-paraffins often occurs as part of an integrated LAB plant where the producers start from kerosene as raw material.
This page was last edited on 30 Augustat Since the s, LABs have emerged as the dominant precursor of biodegradable detergents.
Advances in Neutrino Technology. There is 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.
Retrieved 22 Dec Hydrotreated kerosene is a benzenr feedstock for high purity linear paraffins n-paraffinswhich are subsequently dehydrogenated to linear olefins:. Important product characteristics include the bromine index, sulfonatability, msdw of 2-phenyl isomers 2-phenylalkanethe tetralin content, amount of non-alkylbenzene components, and the linearity of the product.
Nuclear Physics B – Proceedings Supplements. LAB has been subject to concern about its effect on the environment and human health. Each process generates LAB products with distinct features. Consequently, most LAB plants built since then have utilized this process. Views Benzdne Edit View history. Ullmann’s Encyclopedia of Industrial Chemistry.
The process eliminates catalyst neutralization and HF disposal.
Linear alkylbenzene – Wikipedia
Given the large scale applications of LAB-derived detergents, a variety routes have been developed to produce linear alkylbenzenes: The life-cycle analysis considered the emissions and resulting environmental and human exposures. The resulting linear mono-olefins react with benzene in the presence of a catalyst to produce the LABs. Hydrogen fluoride HF and aluminium chloride AlCl 3 are the two major catalysts for the alkylation of benzene with linear mono-olefins.
From Wikipedia, the free encyclopedia.
Following the exposure assessment, the environmental risk characterization for each protection target in the aquatic, terrestrial and soil compartment was determined.
The linrar concludes that there are no concerns for the environment or human health. 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. Archived from the original PDF on Other names LAB, linear alkyl benzene.
A desulfurization process is needed to reduce the sulfur content of some n-paraffins. Alternatively, ethylene can be oligomerized partially polymerized to produce linear alkenes.
LAS replaced branched dodecylbenzene sulfonateswhich were phased out because they biodegrade more slowly. 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. Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LASa biodegradable surfactant.
