ABSTRACT:
The present invention relates to a process for obtaining a highly soluble linear alkylbenzene sulfonate with an adjustable 2-phenyl isomer content and an extremely low sulfonation color, in which a catalytic system based on highly stable solid catalysts and with a high selectivity for linear monoalkylated compounds is used.
