Partial Sublimation of Enantioenriched Amino Acids at Low Temperature. Is it Coming From the Formation of a Euatmotic Composition of the Gaseous Phase?.

International audienceThe partial sublimation of enantioenriched amino acids was performed slowly at low temp. with the aim to det. the rules of sublimation of these compds. Although the formation of a euatmotic compn. of the gaseous phase starting from DL + L mixts. of Leu, Pro, and Phe can be deduced from the enantiomeric excess of sublimates, the behavior of the kinetic conglomerate explains the results for D + L mixts. of Ala, Leu, Val, and Pro. Consequently, the enantiomeric excess of the partial sublimate is dependent not only on the studied compd. but also on the compn. of the starting mixt. [on SciFinder(R)
