Factors affecting the extent of branching in fischertropsch synthesis products with iron-based catalysts [PDF]
, 1989 Branched products are mainly formed during secondary isomerization reactions, and not in the main synthesis reaction itself. The extent of branching is a function of the catalyst formulation. High acidity and a low hydrogenation strength of the catalyst (

Kinetics of CO2 with primary and secondary amines in aqueous solutions - I. Zwitterion deprotonation kinetics for DEA and DIPA in aqueous blends of alkanolamines [PDF]
, 1992 The deprotonation kinetics of the DEA—CO2 and the DIPA—CO2 zwitterions have been studied in aqueous blends of amines at 298 K. Amine mixtures investigated were: DEA—TEA, DEA—MDEA, DEA—DMMEA, DEA—DEMEA, DIPA—TEA. DIPA—MDEA, DIPA—DMMEA, DIPA—DEMEA.
