Linear Alkylbenzene (LAB) is a key intermediate for manufacturing biodegradable detergents and surfactants, produced through the catalytic alkylation of benzene with linear mono-olefins derived from kerosene-separated n-paraffins that undergo dehydrogenation. LAB replaced earlier branched alkylbenzene (BAB) surfactants due to its superior biodegradability and cost-effectiveness.
