Milliken® Syn Fac OSA Octenylsuccinic Anhydride
Categories: Other Engineering Material

Material Notes: Octenylsuccinic anhydride, OSA, is prepared from linear 1-octene. It contains few, if any, branched alkyl chains and retains the unsaturation of the parent olefin. The position of the unsaturation is thought to be predominantly as shown below based on theoretical grounds, but the isomer distribution in the product has not been determined. OSA undergoes all the reactions typical for an internal double bond as well as those of carboxylic anhydride.

Chemical Formula: C12H18O3

CAS No: 26680-54-6
