Abstract: | Linear alkylbenzene (LAB) was introduced in the mid-1960s as a raw material for cleaning products. Since then, continuing
and explosive research on its biodegradation and on its environmental and human toxicity has been performed. The efficiency
of linear alkylbenzene sulfonate as surfactant is clearly established, and it is one of the safest and most cost-effective
products in widespread commercial use. The aim of the present paper is to survey the most important developments and understandings
of the chemistry of LAB production and of its physical and environmental properties. The expected consequence of this analytical
survey is to envisage the continuous challenges for the detergents industry in catalytic production of LAB, better control
of selectivity, replacement of corrosive and mineral liquid acid catalyst by heterogeneous acid catalyst and the maintenance
of competitiveness of LAB with respect to natural alcohols. |
