	Factors Controlling Alkylbenzene Sorption to Municipal Solid Waste
		Effects of sorbent decomposition and solvent composition on alkylbenzene sorption were studied by evaluating biodegrad able sorbents in both fresh and anaerobically decomposed form and by complementing single-solute isotherm tests with experiments conducted in acidogenic and methanogenic leachate.
		Alkylbenzene sorption to plastics was greater than to biopolymer composites, and differences in sorbate/sorbent solubility parameter compatibility explained this observation.
		Leachate composition had little effect on alkylbenzene sorption with one exception; volatile fatty acids in acidogenic leachate appeared to convert PVC from a glassy to a rubbery polymer.

	LINEAR ALKYLBENZENE SULFONIC ACID (LAS, LABSA) (Site not responding. Last check: 2007-10-12)
		Linear alkylbenzene sulfonic acid is the largest-volume synthetic surfactant because of its relatively low cost, good performance, the fact that it can be dried to a stable powder and the biodegradable environmental friendliness as it has straight chain.
		Surfactants are widely used in the industry needed to improve contact between polar and non-polar media such as between oil and water or between water and minerals.
		Linear alkylbenzene sulfonic acid is mainly used to produce household detergents including laundry powders, laundry liquids, dishwashing liquids and other household cleaners as well as in numerous industrial applications like as a coupling agent and as an emulsifier for agricultural herbicides and in emulsion polymerization.

	Linear alkylbenzene sulfonates and related compounds (EHC 169, 1996)
		Linear alkylbenzene sulfonates (LAS), alpha-olefin sulfonates (AOS), and alkyl sulfates (AS) are anionic surfactants with molecules characterized by a hydrophobic and a hydrophilic (polar) group.
		1.3.1 Linear alkylbenzene sulfonates Concentrations of LAS have been quantified by means of a specific, sensitive analytical method in almost every environmental compartment in which they might be present.
		LAS are manufactured by reacting the parent alkylbenzenes with sulfuric acid or sulfur trioxide to give the corresponding sulfonic acid, which is then neutralized to the desired salt.

	www.lasinfo.org - Facts & Figures - LAB-LAS Production
		Linear alkylbenzene (LAB), the material used to produce LAS, is derived exclusively from petroleum derivatives: benzene and linear paraffins.
		The total world LAB production capacity in 2002 was estimated at 2.5 million tons, with 300 000 tons being consumed in Western Europe.
		The result of sulphonating LAB is the formation of alkylbenzene sulphonic acid, which has the consistency of a liquid with a high active content (>97%), containing about 1% of unsulphonated matter and 1-2% of H2SO4 (IUCLID, 1994; Schönkaes, 1998).
