| titleOfInvention | Method of manufacturing petroleum resin |
| abstract | The present invention relates to a method for producing a petroleum resin. This manufacturing method heats a mixed fraction containing unsaturated hydrocarbons having a boiling point of 20 to 60 ° C. and a carbon number of 4 to 6 generated during pyrolysis of petroleum such as naphtha and dimerizing the cyclic conjugated diene compound contained in the mixed fraction. Doing; Distilling the obtained product to remove the dimerized cyclic conjugated dienes; In the method for producing a petroleum resin comprising a step of cationic polymerization of the mixed fraction from which the obtained cyclic conjugated dienes have been removed using a Friedel-Craft catalyst, after the step of removing the cyclic conjugated dienes, Separating the removed mixed fraction into fractions (oil B) having fractions of 1/3 of isoprene to 1,3-pentadiene by weight distillation (oil B) and the remaining isoprene (oil A); Converting at least 90% by weight of isoprene in fraction A to methylbutene compounds by partial hydrogenation to prepare fraction C; And further carrying out the step of mixing the fraction C with the fraction B, followed by cationic polymerization of the mixed fraction using a Friedel-Craft catalyst. Provides a method for producing a petroleum resin having a softening point of 70 ~ 120 ℃.n n n This manufacturing method can economically manufacture high quality petroleum resin. |
