Claim 20:
21. A method for preparing a substituted low molecular weight aromatic compound of claim 1, comprising the steps of:
(1) providing a starting material;
(2) subjecting the starting material to a process suitable to obtain at least one low molecular weight precursor compound;
(3) isolating and optionally modifying the at least one low molecular weight precursor compound; thereby obtaining at least one low molecular weight aromatic precursor compound;
(4) subjecting the at least one low molecular weight precursor compound to a sulfonation reaction, wherein one or more substituents are introduced into the at least one low molecular weight aromatic precursor compound; thereby obtaining the at least one substituted low molecular weight aromatic compound;
wherein the starting material is selected from lignocellulosic material, crude oil, coal or pure organic substances.
