LAB See Linear alkylbenzene

During the early 1960s, linear aliphatic olefins, such as a olefins produced via ethylene oligomerization or linear internal olefins produced via catalytic dehydrogenation of linear paraffins, replaced the use of propylene tetramers ia iadustrialized countries, and production of more biodegradable linear alkylbenzene sulfonates (LABS) began (see ADSORPTION, LIQUID SEPARATION) (70). Except ia a few parts of the world, the use of DDES was phased out by 1980. 

The synthetic detergent iadustry has become one of the largest chemical process iadustries (see Detergency). Sales ia 1989 were estimated at more than 4 billion ia the United States alone. As of 1989, the worldwide annual production of linear alkylbenzene (LAB) and branched alkylbenzene (DDB) was estimated to be about 1.8 million tons and 230,000 tons, respectively (71,72).
