ABSTRACT:
A process for preparing a fluid for traction drive from a fraction containing compounds having at least four aromatic rings is disclosed. The fraction is a by-product produced at the time of the preparation of alpha-methyl-benzylalkylbenzenes by alkylation of at least one compound selected from C.sub.7 -C.sub.10 alkylbenzenes with styrene in the presence of an acid catalyst. The process comprises the steps of decomposing the fraction in an atmosphere of hydrogen at a predetermined temperature and pressure, collecting a decomposition product having a boiling range not higher than 450.degree. C. and then subjecting the decomposition product to nuclear hydrogenation at aromatic rings thereof in the presence of a catalyst capable of nuclear hydrogenation.
