AB - Three new, successful resolving agents, namely (S)-2-phenylglycinol, (R)-1-phenylethanaminium (R)-(1-phenylethyl) carbamate and (S)-2-hydroxy-1-phenylethanaminium (S)-(2-hydroxy-1-phenylethyl) carbamate of ibuprofen are presented. The carbamate salts are stable white crystals, they can be easily stored and handled. All salt forming resolution were performed in supercritical carbon dioxide as the only solvent. The enantioseparations were efficient (approx. 50 % enantiomeric purities, > 90 % yields in the crystalline phase) and robust. Unlike previous experiences with primary amine resolving agents, the diastereomeric salt formations and resolutions were competed in short times, even within one hour suggesting that the carbamates are intermediates of the salt formation reaction.

The methodology is presented on the case study of energy integrated distillation columns separating ternary hydrocarbon mixtures of different ease of separations. The economic features involve capital and operating costs; the controllability investigations are based on the evaluation of frequency dependent features and dynamic simulations; the environmental evaluation counts for the CO2 emissions. The results show that the heat integrated scheme is practically the best selection from every point of view. © 2007 Elsevier B.V. All rights reserved.
