No full textUsing different techniques (TG/DTA, XRD and chemical analysis), a comparative
investigation on calcitic and dolomitic mortars, from two different Italian buildings of the
11th and 14th centuries, has been performed. By correlating the thermal effects and the
steps in the TG curves, it has been possible to reach a semi-quantitative evaluation of the
binders in both types of mortars, the results being in good agreement with the chemical
data, and to explain the influence of the other components on the thermal behaviour of
such complex systems

[3-aminopropanol (3-AP), 4-aminobutanol (4-AB), 5-aminopentanol (5-APe), 6-aminohexanol (6-AH)]
with CO/O2 mixtures (O2 = 5 mol%) in the presence of Pd(II)/ligand/NEt3HI catalytic systems. The
catalytic process takes place under very mild conditions (p(CO/O2) = 0.1 MPa; 303–333 K). The target
products can be isolated in high yield through a very simple and straightforward procedure. The catalytic
system can be easily recovered and recycled for several times.
The influence of a few reaction parameters (nature of ancillary ligand and iodide co-catalyst, I/Pd
molar ratio, etc.) on the catalytic activity has also been investigated and the mainmechanistic features of
the catalytic process fully elucidated
