Direct Insertion Probe–Mass Spectrometry (DIP–MS) Maps and Multivariate Analysis in the Characterization of Crude Oils

Autor: Cristina Flego, Carla Zannoni

Publikováno v: Energy & Fuels. 27:46-55

Crude oils are complex organic mixtures, with their composition changing not only with the geographical region but also with the oil field. Chemical fingerprinting of crude oils and the knowledge of dependence of their macrophysical properties from t

Direct Insertion Probe−Mass Spectrometry: A Useful Tool for Characterization of Asphaltenes

Autor: Carla Zannoni, Cristina Flego

Publikováno v: Energy & Fuels. 24:6041-6053

The direct insertion probe−mass spectrometry (DIP−MS) technique, routine analysis for labile and polar samples, is based on the introduction of samples directly into the ionization chamber, followed by their vaporization and eventual ionization b

We synthesize a new ortho-xylenyl-bridged substituted metallocene catalyst which surprisingly affords ethylene-1-hexene copolymers with broad molecular weight distribution (MWD), when activated with methylaluminoxane (MAO). In order to investigate th

The dynamics of amorphous aromatic polyesters consisting of poly( ethylene terephthalate)(PET), poly( ethylene isophthalate)(PEI), and poly( ethylene 2,6-naphthalenedicarboxylate) (PEN) has been investigated by means of solid state CPMAS 13 C NMR. Pr

Propylene-Styrene Multiblock Copolymers: Evidence for MonomerEnchainment via Opposite Insertion Regiochemistry by a Single-SiteCatalyst

Autor: Antonio Proto, Francesco De Carlo, Carla Zannoni, Carmine Capacchione, Jun Okuda

Polymerization of propylene promoted by the post-metallocene catalyst 1 and methylaluminoxane (MAO) produces oligomers containing prevailingly unsaturated chain ends which are diagnostic of a primary (1,2) regiochemistry of insertion. The styrene pol
