Synergistic roles of platinum nanoparticles and sodium ions within beta zeolites in n-alkylation of amines with aromatic alcohols

N-alkylamines synthesis through N-alkylation of amines with alcohols catalyzed by Beta zeolites encapsulated Pt nanoparticles

27-Oct-2023 - Organic N-alkyl amines are important chemical products and intermediate with wide applications in the fields of daily chemicals, pesticides, pharmaceuticals, surfactants, and life sciences. The C–N bonds formed by alkylating reagents (halocarbons, metal halides, etc.) to produce amines usually ...

Chemist created a niobium-silica catalyst to boost petrochemical reactions

Catalyst reduces the time of alkylation reactions from several hours to just 10 minutes

08-Oct-2020 - Alkylation reactions are used in the petrochemical industry to obtain high-octane number components for gasolines. A chemist from RUDN University found a way to speed this process up to 24 times. To do so, he developed a catalyst based on silica and niobium. The results of his work were published ...

Creating chiral carbons

23-Jan-2009 - South Korean scientists have developed a racemisation-resistant substrate that can be selectively alkylated to make new chiral carbon centres. Although there are many ways to make chiral carbon centres by alkylating carbonyl compounds, until now scientists have been unable to asymmetrically ...

Chemistry for a Raney day

02-Dec-2008 - Spanish and Mexican scientists have stumbled across a new way to monoalkylate amines that they claim is more environmentally friendly than alternative routes. José García Ruano, at the Autonomous University of Madrid, and colleagues were using Raney nickel to cleave nitrogen–sulfur bonds in ...
