Lignin, obtained through steam explosion from straw, was completely characterized via elemental analysis, gel permeation chromatography, ultraviolet and infrared spectroscopy, and 13 C and 1 H… Expand
On the origin of “Goût de Lumiere” in champagne
The flavour of champagne before and after UV irradiation was analysed by using SPME (solid phase microextraction). Fourteen components in the flavour were detected; some significant modifications in… Expand

Direct irradiation for 100h of crude oil from Basilicata (Southern Italy) gave in the case of linear and branched alkanes a reduction of 9 and 5%, respectively. On the contrary, cyclic alkanes… Expand
The effect of heat and light on the composition of some volatile compounds in wine.
Abstract HS-SPME–GC–MS analysis of Aglianico del Vulture red wine from Southern Italy showed the presence of ethyl acetate, 3-methyl-1-butanol, 3-methylbutyl acetate, ethyl hexanoate, diethyl… Expand
FT–ICR–MS analysis of lignin
Fourier transform ion cyclotron resonance mass spectrometry (FT–ICR–MS) of a steam-exploded lignin from wheat straw showed that fragments with a mass higher than 4534 Da cannot be obtained.… Expand
The Paterno-Buchi Reaction on Furan Derivatives
The Paterno-Buchi reaction on furan derivatives is reviewed. The photochemical reaction of furan derivatives in the reaction with carbonyl compounds gives the corresponding monoadduct with high… Expand
On the stereoselectivity of the Paternò–Büchi reaction between carbonyl compounds and 2-furylmethanol derivatives. The case of aliphatic aldehydes and ketones
Abstract The Paterno–Buchi reaction between 2-furylmethanol derivatives and aliphatic aldehydes and ketones induced by irradiation through Vycor at 8°C shows high regioselectivity but no… Expand
Synchronous fluorescence spectroscopy and gas chromatography to determine the effect of UV irradiation on crude oil
Abstract The fate of the crude oil under irradiation was studied. After the UV irradiation, the fraction present in the highest percentage shifted from C8–C9 fraction to C13 one, in GC–MS analysis.… Expand
The stereoselectivity of the Paternò-Büchi reaction between tertiary 2-furylmethanol derivatives and aromatic carbonyl compounds: on the nature of the hydroxy directing effect.

The photochemical reaction of 1-(2-furyl)-1-phenylethanol with benzaldehyde gave a mixture of regioisomeric products. The adduct obtained on the more hindered side of the molecule was obtained with… Expand
Diastereoselectivity in the Paternò-Büchi reaction on furan derivatives
Abstract The reaction of benzoin, 4,4 ′ -dimethoxybenzoin and benzoin ethyl ether with furan gave the corresponding adduct with high diastereoselectivity (71–100%). The diastereoselectivity was… Expand
