Direct sulfation of a Zr-based metal-organic framework to attain strong acid catalysts
(Elsevier Science, 2019-08)
The application of Metal-Organic Frameworks (MOFs) in gas phase heterogeneous catalysis is still not widely spread because of their limited stability under reaction conditions. Obtaining stable acidic MOFs to be used in ...
Reaction between N-alkylhydroxylamines and chiral enoate esters: More experimental evidence for a cycloaddition-like process, a rationale based on DFT theoretical calculations, and stereoselective synthesis of new enantiopure β-amino acids
(American Chemical Society, 2002-12)
The reactions between N-benzyl- and N-methylhydroxylamine and chiral enoate esters, derived from D-glyceraldehyde and (-)-verbenone, respectively, have been investigated. Theoretical calculations show that the most favorable ...
Review on Reaction Pathways in the Catalytic Upgrading of Biomass Pyrolysis Liquids
(American Chemical Society, 2021-09)
Bio-oils are the liquid products from the pyrolysis of biomass, which captured pronounced attention and showed relevance as an alternative source of fuels and chemicals. Bio-oils are complex mixtures of a large number of ...
Synthesis of oligomeric silsesquioxanes functionalized with (β-carboxyl)ester groups and their use as modifiers of epoxy networks
(Pergamon-Elsevier Science Ltd, 2007-07-27)
A silsesquioxane functionalized with (β-carboxyl)ester groups was synthesized by reacting a silsesquioxane functionalized with secondary hydroxyls with a stoichiometric amount of an acid anhydride. The reaction could be ...
Asymmetric Organocatalytic C-C Bond Forming Reactions with Organoboron Compounds: A Mechanistic Survey
(Wiley VCH Verlag, 2019-05-26)
The recent development of asymmetric organocatalytic C-C bond forming reactions involving organoboranes has attracted big interest in the synthetic community. Asymmetric organocatalytic additions to enones, aldehydes, ...
Synthesis and characterization of a waterborne polyurethane made from castor oil and tartaric acid
(Pergamon-Elsevier Science Ltd, 2018-05)
Waterborne polyurethanes (WBPUs) based on the reaction of unmodified castor oil (CO) with isophorone diisocyanate (IPDI) were synthesized using dimethylolpropionic acid (DMPA) or tartaric acid (TA) as internal emulsifiers. ...
Pressure sensitive adhesives based on epoxidized soybean oil: correlation between curing conditions and rheological properties
(Springer, 2018-04-24)
Renewable resources, including vegetable oils, can be used as feedstock for the manufacture of pressure sensitive adhesives (PSA) that can compete with those derived from petrochemical sources, but with the environmental ...
Curing behavior and properties of high biosourced epoxy resin blends based on a triepoxy monomer and a tricarboxylic acid hardener from 10-undecenoic acid
(Elsevier, 2020-01)
Renewable propane-1,2,3-triyl tris(9-(oxiran-2-yl) nonanoate) (EGU, 100 wt% biogenic) and a tricarboxylic acid triglyceride (CGTU) hardener (85.7 wt% biogenic) were synthesized from 10-undecenoic acid (10-UDA) and used to ...
Experimental and theoretical studies on polar Diels–Alder reactions of 1-nitronaphathalene developed in ionic liquids
(Royal Society of Chemistry, 2013)
The reactions between 1-nitronaphthalene 1 and two nucleophilic dienes, Danishefsky´s diene 2 and 1-trimethylsilyloxy-1,3-butadiene 3, to yield phenanthrenols 7 and 8 developed in protic and aprotic ionic liquids (ILs) ...
Epoxy vitrimers with a covalently bonded tertiary amine as catalyst of the transesterification reaction
(Pergamon-Elsevier Science Ltd, 2019-02)
Tertiary amines are one of the typical catalysts used to accelerate transesterification reactions in epoxy vitrimers. Instead of adding a tertiary amine (e.g. tributylamine, TBA) to the initial formulation, secondary (e.g. ...
