sodium and calcium with high intensities as well as poly(dimethyl siloxane), different fatty acids, wax alcohols,

Yet it is still needed as a precursor for the chemical synthesis of many compounds, mainly ethylbenzene, cumene, cyclohexane, nitrobenzene, and
alkylbenzene. The most important consumers of benzene are manufacturers of ethylbenzene, who process more than half of total global consumption.
The objective of this research is to experimentally determine the stability and compatibility of candidate lubricants (such as naphthenic and paraffinic mineral oils, uncapped and capped polyalkylene glycols, linear, branched and mixed polyolesters, and
alkylbenzene) with C[O.sub.2] and typical compressor materials of construction such as iron, copper and aluminum.

The largest and most commonly used class of surfactants, the anionic surfactants, include chemistries like
alkylbenzene sulfonates, fatty acid soaps, and dialkyl sulfosuccinates.
Investigation of an onsite wastewater treatment system in sandy soil: Sorption and biodegradation of linear
alkylbenzene sulfonate.
A surfactant (linear
alkylbenzene sulfonic acid, LAS) is used to dissolve the 1,2,4-trimethyl-benzene, or pseudocumene (PC), which is a common LS material, in water.
Synergetic effects of aromatics (benzene, toluene xylene and
alkylbenzene) were negative for the 50/50 blend, but positive for the 70/30.
Taipei, April 23, 2012 (CENS) -- Buoyed by increasing output, the Taiwan-based Ho Tung Chemical Corp., a large-sized manufacturer of detergent materials as linear alkyl benzene (LAB), normal paraffin (NP) and linear
alkylbenzene sulfonate (LAS), ambitiously aims to become the world's second-largest supplier of its kind in 2013.

It has been found that there is accumulation in lysosomes of the anionic detergent linear
alkylbenzene sulfonate leading to inhibition of lysosomal enzymes like ACP and ALK (Bragadin et al., 1996).
DDT, aldrin, dieldrin, heptachlor, chlordane, kepone, nonylphenol, and
alkylbenzene sulfonate) have shown 'hockey-stick' shaped loss curves involving an initial stage of relatively rapid loss followed by little or no loss (Alexander 1995).
