20, 2011 /PRNewswire-USNewswire/ -- An independent Expert Panel of interdisciplinary scientists is calling for information on fragrance ingredient groups: Aromatic Ketones
, Alkyl and Cyclic Alkyl Nitriles and Aryl and Akyl Aryl Nitriles that are under study by the Research Institute for Fragrance Materials, Inc.
Acetophenone yields more Pinacol indicating that aromatic ketones
are more prone to the formation of the Pinacol.
This type of photoinitiator includes the aromatic ketones
7] combined the methods of UV-, IR-, NMR H and 13C spectroscopy and showed that in shale oil fraction 300-320 [degrees]C aromatic ketones are not prevalent, and ketones are represented mostly by alicyclic ketones and alkanones.
In these fractions they are represented by aliphatic saturated and unsaturated ketones, cycloketones, aromatic ketones, alkyl benzofurans, alkyl benzothiophenes, etc.
This band results from the stretching of ketone carbonyls and suggests the formation of aromatic ketones
