In the foregoing process, the molar ratio of methanesulfonic acid to the D-(-)-tartrate salt of (1S,2S)-1-(4-hydroxyphenyl)-2-(4-hydroxy-4-phenylpiperidin-1-yl)-1-propanol is preferably in the range of 1.3 to 1.0. More preferably, the molar ratio of methanesulfonic acid to the D-...
The theoretical molar fluxe of each gas was obtained by an approximate solution of mass balances with reaction regions of the first order reaction of CO 2 and instantaneous reactions of SO 2 and NO 2 in CO 2 -SO 2 -NO 2 -AMP system. From the comparison between the theoretical total ...
The hydrogen bond interaction between two AMP derivatives (AMPH+ and AMPCO2−) and one TEPACO2−(P)H+(S3) molecule were simulated, taking into account the molar ratio of TEPA to AMP (Fig. 9(b)). The results showed that AMPH+ and AMPCO2− were respectively linked to the carboxyl ...
