An efficient synthesis of warfarin acetals on montmorillonite clay K-10 with microwaves [PDF]

open access: diamondJournal of the Serbian Chemical Society, 2002
The microwave promoted reaction of warfarin with methanol, or ethanol, in the presence of montmorillonite clay K-10 as a catalyst, affords the corresponding acetals, 2-methoxy-2-methyl-4-phenyl-3,4-dihydro-2H-pyrano[3,2-c]chromen-5-one (2) and 2-ethoxy-2-

Preparation and Characterization of Immobilized Molybdenum Complex on Pillared Montmorillonite K-10

open access: diamondMalaysian Journal of Science Health & Technology, 2018
This study was carried out to immobilize molybdenyl (VI) acetylacetonate (MoO2(acac)2) complex on alumina pillared montmorillonite K-10 (MMT K-10). Pillar MMT K-10 was produced by introducing MMT K-10 with a hydrolysis solution of NaOH with AlCl3. Different concentrations of pillaring solution were prepared in terms of OHto Al3+ ratio (0.5, 1.0, 1.5 ...

Spectroscopic studies on Rhodamine B intercalated K-10 montmorillonite aqueous dispersions [PDF]

open access: diamondIOP Conference Series: Materials Science and Engineering, 2015
In this paper, the optical absorption and fluorescence studies on rhodamine B (RB) intercalated acid activated K-10 montmorillonite dispersions is presented. The aqueous dispersions were prepared from the dried dye intercalated montmorillonite. The absorption and fluorescence peaks of RB dispersions show a bathochromic shift with respect to the dye ...

Isomerization of Terpinolene Oxide in the Presence of Montmorillonite K-10 Catalyst

open access: diamondJournal of Japan Oil Chemists' Society, 1992
The isomerization of terpinolene oxide (1) in the presence of montmorillonite K-10 catalyst was studied. High selectivity of Karahanaenone [(2), 2, 2, 5-trimethy1-4-cyclohepten-1-one, isolated yield 82 %] was attained by the simple solid-liquid phase heterogeneous reaction.
