TL;DR: In this paper, the Verbascum stalk mill was converted to liquid products by using organic solvents, such as methanol, ethanol and acetone, with catalysts (10% NaOH or ZnCl 2 ) and without catalyst in an autoclave at temperatures of 533, 553 and 573 K.

TL;DR: Acetone-butanol fermentation by Clostridium aurantibutyricum ATCC 17777 utilizing a model medium for palm oil mill effluent (POME) was investigated and resulted in a reasonable oil hydrolysis rate between those obtained in cultures with constant pHs of 6.2 or 5.5, and higher solvent productivities than in either of the single-pH cultures.

TL;DR: In this article, volatile compounds from dry cured hams were tentatively identified by gas chromatography retention times and further verification of the compounds made by infrared spectroscopy, and selective trapping was used to identify hydrogen sulfide and trace amounts of disulfides and/or monosulfides.
Abstract: SUMMARY
Volatile compounds isolated from dry-cured hams were tentatively identified by gas chromatography retention times and further verification of the compounds made by infrared spectroscopy. These compounds were as follows: formaldehyde, acetaldehyde, propionaldehyde, isobutyraldehyde, n-valeraldehyde, isovaleraldehyde, acetone, diacetyl, methyl ethyl ketone, formic acid, acetic acid, propionic acid, butyric acid, and isocaproic acid. RF values and selective indicators were used to identify ammonia and methylamine. Selective trapping was used to identify hydrogen sulfide and trace amounts of disulfides and/or monosulfides.

TL;DR: In this article, a gaseous sensor for ester vapors has been developed based on their chemiluminescence (CL) on the surface of nano-sized SiO 2 in an airflow.
Abstract: A gaseous sensor for ester vapors has been developed based on their chemiluminescence (CL) on the surface of nano-sized SiO 2 in an airflow. The luminescence characteristics and the optimal conditions for the determination of ethyl acetate by the sensor are investigated. Under the optimized conditions, the linear range of the CL intensity versus the concentration of ethyl acetate vapor is 20–300 ppm with a limit of detection of 3.0 ppm (3 σ ) and a relative standard deviation (R.S.D.) of 1.80% for eight times determination of 300 ppm ethyl acetate. There is no response or weak response when foreign substances including ethanol, methanol, hexane, cyclohexane, benzene and toluene pass through the sensor. However, acetone shows a little response which interferes slightly in the measurement of ethyl acetate. The sensor exhibits good stability and durability after 100 h reaction with 300 ppm ethyl acetate. The possible mechanism of CL from the oxidation of ethyl acetate on SiO 2 is discussed based on the CL spectra and the GC–MS chromatogram of reaction products.
