Succinic Acid → HCID 86589099, compound

Temperature

40 °C

10.0 g dry LDEE were suspended in 50 ml absolute alcohol. 2.622 g Succinic acid (0.5 equivalent) dry powder were introduced and 30 ml of water were added to the mixture with stirring. After complete dissolution of the solids, the solution was transferred to a round-bottom flask. The solvent was evaporated in Rotavapor under vacuum and the evaporation flask was heated in a water bath (40° C.). After the solvent evaporation, 80 ml Toluene were introduced to the residue and evaporated under the same conditions. The solid evaporation residue was dried under vacuum at room temperature and ground in a mortar. The resulting white flowable powder has a melting range of 93.4-95.9° C. The hygroscopicity test at RH=80% and T=20±2° C. showed a weight gain of 0.27% during 24 hrs.
