Process for preparing a fluid for traction drive. |
摘要 |
<p>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-methylbenzylalkylbenzenes by alkylation of at least one compound selected from C₇-C₁₀ 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°C and then subjecting the decomposition product to nuclear hydrogenation at aromatic rings thereof in the presence of a catalyst capable of nuclear hydrogenation. </p> |
