Abstract
PURPOSE: To prepare high quality title compound without causing troubles of sublinated maleic anhydride, by adding an aliphatic alcohol to the reaction produce of an olefin with maleic anhydride, and heating the mixture under reduced pressure to distil out the unreacted raw materials.
CONSTITUTION: An alkenylsuccinic acid is prepared in high purity, by (1) reacting an olefin with maleic anhydride, (2) adding a 1W3C aliphatic alcohol to the reaction mixture to esterify the remaining maleic anhydride, and (3) heating the product under reduced pressure to distil out the unreacted alcohol, the unreacted olefin, and maleic acid esters. The alkenylsuccinic acid thus obtained can be converted to a salt by neutralizing with a base.
EFFECT: Blocking of a vacuum pump, vacuum lines, etc. with sublimated maleic anhydride, can be prevented.
