Ascorbic acid as a dispersant for concentrated alumina nanopowder suspensions Çınar, Simge (Elsevier BV, 2014-08-01) The stabilization of concentrated nanopowder suspensions is crucial for many industrial applications. Yet, controlling the suspension viscosity is challenging for nanopowder suspension systems. In this study, we examined the adsorption of L-ascorbic acid (Vitamin C) on alumina surfaces and the related reduction in viscosity of the suspensions. Interactions between the ascorbic acid and the alumina surface were investigated by in situ ATR-FTIR and zeta potential measurements. It was shown that ascorbic acid ...
Aspergillus niger mediated a-hydroxylation of cyclic ketones Karabacak, Elife Özlem; Ögel, Zümrüt Begüm; Department of Food Engineering (2006) Chiral a -hydroxy ketones are important structural units in many natural products, biologically active compounds and the hydroxyl group has frequently been used as a reagent directing group, such as for the selective elaboration of aldol products. In this work, enzymatic synthesis of both enantiomers of the a -hydroxy ketones (2-hydroxy indanone, 2-hydroxy tetralone) using Aspergillus niger by selective α-oxidation of ketones (1-indanone, 1-tetralone) was studied. The α-oxidation of ketones was carried out ...

Asymetric synthesis of 1,4-diamine based chiral ligand and organocatalyst and their applications Ortaylı, Oytun; Tanyeli, Cihangir; Department of Chemistry (2010) Novel 1,4-chiral diamine ligand possessing a trans-9,10-dihydro-9,10-ethanoanthracene backbone was synthesized. The synthetic plan involves first LiAlH4 reduction of the Diels-Alder adduct obtained by reaction of dimenthyl fumarate and anthracene, which is followed by reacting the corresponding alcohol and subsequent attachment of mesylate and triflate units to get good leaving groups which are available substances for introducing nitrogen units via SN2 type reactions. Consequently, by using dimesyl ester a...
