Aldehydes and ketones
... • Neither aldehydes nor ketones possess the ability to H-bond with other molecules like themselves. Consequently, boiling points for aldehydes and ketones are lower than for alcohols of similar molar mass. • The C-O double bond in these molecules is polar, so dipoledipole forces do exist. As a resul ...

... Although TPAP is at its most active when absolutely fresh, and activity is lost almost immediately, we have shown that there is minimal further loss between one and six days after synthesis, if stored at low temperatures (Table 1). Further to this, UV analysis of TPAP showed little change in either ...

Propolis (bee glue): an unusual mordant for gilding in Italian
... These differences could result from the highly variable nature of propolis, or may be linked to changes that occur on ageing. It is possible that the phenylpropenoic acids and esters could crosslink. If cross-linking occurs then this might explain why only benzoic acid derivatives were detected in t ...
