| 摘要 |
Olefinically unsaturated hydrocarbons, in particular dimeric or polymeric isobutene derivatives, which have a mean number average molecular weight Mn of from 100 to 3000, are reacted with maleic anhydride in a molar ratio of maleic anhydride to olefin of from 0.2 to 3.0, in the presence of from 1 to 5000 ppm by weight of an alkoxide of titanium, of zirconium, of vanadium or of aluminum, at from 150 DEG to 280 DEG C., with formation of the corresponding succinic anhydride. These products are used for the preparation of anticorrosive agents or oil additives. |
