The thermal behaviour of some clathrates based upon Dianin's Compound

Clathrates based upon Dianin's Compound (4-p-hydroxyphenyl-2,2,4-trimethylchroman) exhibit shape and size selectivity towards included guest molecules in a manner similar to that shown by some commercially important zeolites. Clathrates derived from Dianin's Compound and a wide range of guest solvents were heated to their melting points and beyond, and their behaviour observed.

Zusammenfassung Auf Dianin's Verbindung (4-p-Hydroxyphenyl-2,2,4-trimethylchroman) basierende Klathrate weisen gegenüber eingeschlossenen Gastmolekülen eine ähnliche Form- und Grössenselektivität auf wie einige wichtige kommerzielle Zeolithe. Von Dianin's Verbindung und einer Reihe von Lösungsmitteln erhaltene Klathrate wurden bis zum Schmelzpunkt und darüber hinaus erhitzt und dabei ihr Verhalten beobachtet.
