Abstract: A method for preparing 1,2-propanediol involves reacting propene with hydrogen peroxide, in the presence of a phase transfer catalyst and a heteropolytungstate, in a liquid reaction mixture containing an aqueous phase with a maximum apparent pH of 6 and an organic phase containing a solvent having a solubility in water at 20° C. of less than 500 mg/kg. The method then involves separating the liquid reaction mixture into an aqueous phase containing 1,2-propanediol and an organic phase; recycling at least a part of the separated organic phase to the reaction; and extracting the separated aqueous phase with an extractant solution containing the same phase transfer catalyst and solvent as used in the reaction to provide an extracted aqueous phase and an extract phase. The method further involves recycling at least a part of the extract phase to the reaction and recovering 1,2-propanediol from the extracted aqueous phase.

Abstract: The present invention relates to a sensing composition for detecting a volatile organic compound in its gas phase, comprising 1) a silylated cellulose selected from the group of trialkylsilyl cellulose, triarylsilyl cellulose and alkylarylsilyl cellulose; and 2) a fluorescent dye. The detection of a volatile with this sensing composition comprises placing the sensing composition (optionally present as a layer on a support) in the vicinity of a potential source of a volatile and analyzing the sensing composition to determine whether a volatile of the potential source has reached the sensing composition. This detection can be performed in a quantitative manner by means of spectrophotometric analysis, and/or by image analysis of the sensing composition. The invention is particularly useful for application in high throughput screening.
