The thermodynamics, mechanism and kinetics of the catalytic conversion of propylene and water to diisopropyl ether over amberlyst 15
… step from a feed of propylene and water over Amberlyst 15 ion exchange resin catalyst. It was produced in a trickle bed reactor at pressures between 1 bar and 60 bar, at temperatures between 70°C and 160°C and at overall propylene to water ratios between 1:5 and 10:1. Reaction proceeded in the …

Polymer-supported reagents for disinfection of water
… of the strong acid cation exchange resin, Amberlyst-15. The products obtained after treatment contained -SO2NH2 and -SO 3H groups. The sulfonic acid groups were determined by a total ion exchange capacity measurement. The sulfonamide groups were chlorinated mainly to the dichlorosulfonamide …

Development of zeolite based acid catalysts for the synthesis of methyl tertiary butyl ether
… and isobutene over an acidic ion-exchange resin Amberlyst-15. This commercial catalyst, although very active, still suffers from several drawbacks such as thermal instability, acid leaching, and need of a high methanol over isobutene ratio. Zeolites for their higher thermal stability and shape …

Prozessorientierte Untersuchungen zur Schmierstoffsynthese basierend auf Ölsäuremethylester und Glycerintrioleat
… and selectivity. Best results were obtained with Amberlyst 15 and the similar Dowex Marathon C catalyst. With the collected expertises in lab scale the 25-l-pilot plant was optimized. An automated and computer controlled reaction procedure minimized unwanted side reactions (over-night stand still …
