Solubility temperature and crystallization
WebFeb 6, 2024 · After this initial decrease in both enantiomers, racemization of (R)-1 into (S)-1 occurred over 8 h while a reaction temperature of 70 °C was maintained.The unchanging (S)-1 concentration over this time suggested that the rate of (S)-1· L-DBTA crystallization was faster than the rate of (R)-1 racemization.Additionally, racemization ended before the two … WebThe anions were sorted according to their respective quotient (see Table 1) of the amine donor (IPA and ammonium) salt solubility to the product salt solubility ((S)-1PEA).In addition, acid anions resulting in high product salt solubilities (e.g. 25CNA) >25 mM and low amine donor salt solubilities (e.g. 3DPPA) <150 mM were excluded to maximize product …
