Nanocoating of Hydrophobic Mesoporous Silica around MIL-101Cr for Enhanced Catalytic Activity and Stability

The metal-organic framework (MOF) MIL-101Cr was readily encapsulated by a very thin shell (around 30 nm) of hydrophobic mesoporous silica, which replicates the irregular shape of the MOF nanocrystals. Such a silica shell facilitates the diffusion of hydrophobic reactants with enhancement of the catalytic activity of the MOF and significantly improved catalytic stability of the MOF in the oxidation of indene.

Colloidal Nobel Metal Catalysts Protected by Surfactant Micelles. Regio-Selectivity in the Hydrogenation of Unsaturated Fatty Acids in Organized Media
Toshima, Naoki,Takahashi,Tadahito
, p. 573 - 576 (1988)
Colloidal dispersions of platinum and palladium protected by nonionic surfactants were prepared by photo-irradiation.They work as active catalysts for the hydrogenation of unsaturated fatty acids and their sodium salts.The regio-selectivity was observed in the hydrogenation in the organized media which surround the colloidal particles.Thus, 10-undecenoic acid was more rapidly hydrogenated than 2-undecenoic acid

Expeditious and benign methods for primary alcohol- carboxylicacid conversions with TEMPO were developed in abiphasic system composed of aslightlymiscible ether (THP) and aqueous layer. Easily available co-oxidants such as Py-HBr3, Bu4NBr3, and electrooxidation were successfully applied to generate N-oxoammonium species as a recyclable catalyst.

Synthetic method of acid compound
-
Paragraph 0028-0033; 0066-0081, (2020/08/25)
The invention belongs to the field of organic synthesis, and particularly relates to a synthetic method of an acid compound. An acid anhydride compound and an alkyl bromide or a functionalized alkyl bromide are subjected to a cross-electrophilic coupling reaction to synthesize an acid compound, so that the application of the alkyl bromide in the cross-electrophilic coupling reaction is expanded, and a novel non-traditional method for chemically and selectively constructing a carbon-carbon bond through a decarburization process is provided. The synthesis method is simple, economic, green and environment-friendly, and has wider applicability or is suitable for large-scale production.
Process for the preparation of fatty acids

Paragraph 0179-0206; 0213-0215, (2020/09/04)
The invention discloses a method for preparing fatty acid. The method comprises the following steps: providing a first reactant which is a furan compound containing an carbonyl group; providing a second reactant which is a compound containing a carboxyl group, an ester group or an anhydride group and can participate in a condensation reaction with the carbonyl group of the first reactant; allowingthe first reactant and the second reactant to participate in a first condensation reaction, and allowing a C=O bond of the carbonyl group of the first reactant to be connected with alpha carbon of the carbonyl group of the second reactant and to be converted into a C=C bond so as to form a condensation product; and carrying out a second-step reaction under hydrogen pressure in the presence of a co-catalytic system of a hydrogenation catalyst and Lewis acid, opening a furan ring of the condensation product, carrying out hydrodeoxygenation at the same time, removing all oxygen except for oxygenin the carboxyl group, and allowing a carbon chain to be saturated so as to obtain the fatty acid.
