Abstract Using a combination of IR and UV techniques, evidence is presented for inclusion complex formation between mucochloric acid and B-cyclodextrin in acidic aqueous solutions. UV evidence supports the conclusion that under these acidic conditions mucochloric acid-B-cyclodextrin complex could be isolated by recrystallization of a 1:1 mole ratio of the above compounds from water at pH2. Solid sample IR (KBr or nujol) showed a carbonyl shift of approximately 20 cm(sup minus 1) when mucochloric acid was compared to the mucochloric acid-B-cyclodextrin complex. No such shift was found upon simply grinding together the above components. Thus the carbonyl shift is ascribed to inclusion complexation of mucochloric acid into the B-cyclodextrin cavity. Melting point and thin layer chromatographic analyses also yield supporting evidence for the formation of solid mucochloric acid-B-cyclodextrin complexes. Pilot studies with 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5h)-furanone (MX), suggest a similar B-cyclodextrin-complex formation in acidic solutions.
