WebApr 12, 2024 · Due to the availability of (R)- and (S)-selective TAs, both diastereomers of the 1,3-amino alcohol motif were accessible. A two-step process enabled the synthesis of the desired amino alcohols with up to three chiral centers with de up to >97 in the final products. Web[eng] Zeolite NaA membranes have attracted special attention in the last years in light of their high selectivities (>40000) and fluxes in the dehydration of alcohol/water mixtures. This Ph.D. thesis is aimed at developing new methods for zeolite NaA membrane synthesis together with the characterization of their mass transfer mechanisms for their further …
