| titleOfInvention | Method for production of low bromine number fraction |
| abstract | A fraction of low bromine number mainly containing a styrenic compound/aromatic compound adduct can be attained, by feeding reaction materials of a styrenic compound and an aromatic compound to a fixed-bed flow reactor packed with a solid acid catalyst in a liquid phase at a temperature in the range of 40 to 350 DEG C to form a styrenic compound/aromatic compound adduct, in which (1) the feed of reaction materials is stopped when the bromine number of the above fraction is increased up to a predetermined value, (2) a saturated aromatic hydrocarbon having a mean value of the proportion of aromatic ring carbons in a molecule of 55% or more is fed to the reactor in a liquid phase at a temperature higher by 5 to 150 DEG C than that of the reaction mixture just before the above stopping, and (3) the feed of reaction materials is then restarted to obtain the fraction. |
