General description

Mixtures of TiO2 (P25) with rare earth oxides (La2O3 or Y2O3) calcined at 700°C or 650°C efficiently causes oxidation of acetone. Its Aldol condensation in vapor-phase has been investigated over MgO promoted with alkali (Li, Na, K and Cs) or alkaline earth (Ca, Sr and Ba) metal ions. It undergoes Aldol condensation in the presence of Mg-Al layered double hydroxides (LDH) as catalysts and Cl- and/or CO32- as compensating anions to afford diacetone alcohol and mesityl oxide. Enantioselective Aldol condensation of acetone with various isatins in the presence of dipeptides (catalyst) has been described.

Application

Acetone′s luminesence intensity is dependent upon the solution components . The absorption of UV light by acetone, results in its photolysis and the production of radials .
Acetone has been used in the preparation of 13wt% amorphous poly (lactic acid) (PLA) solution, which was required for the preparation of electrospun PLA membranes.

Nonylphenols (NP) are ubiquitous substances that have been detected in highly diverse foodstuff. As breakdown products of nonylphenol ethoxylates, NP could end up in the aquatic environment. This article presents a rapid method for NP detection in surface water by planar solid phase extraction – planar yeast estrogen screen (pSPE-pYES).
