WebApr 7, 2024 · Along with increased purity, a slow crystallization process also encourages the growth of larger crystals. Figure 3.17 shows crystallization of acetanilide from water with two different rates. The crystals grown in Figure 3.17a were formed much more quickly, and are smaller than the slower grown, larger crystals in Figure 3.17b. 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 …
