Methylated spirits are mainly composed of ethyl alcohol, otherwise known as ethanol. Other additives in methylated spirit, such as methanol, isopropyl alcohol, acetone, and other substances which make it toxic to deter people from drinking it. Answer and Explanation:1 Ethanol has two carbon atoms ...
It can be seen from the solubility profiles that all the solubility of doxifluridine in the mixed solvents increases with the increasing mass fraction of the co-solvent (methanol, ethanol or acetone) and the experimental temperature. The minimum and maximum mole fraction solubility of doxifl...
as feeding the raw polypentanol into a high-temp vacuum molecular distilling evaporator at a certani speed, distilling, feeding the distilled substance into another high-temp vacuum molecular distilling evaporator at a certain speed, and distilling to obtain the high-purity (70-95 mass%) product....
Odours (n = 7; heptanone, isoamyl acetate, limonen, ethyl valerate, pentanol, propyl butyrate and nonane; Sigma-Aldrich, St. Louis, MO) were diluted 1 × 10−3 in mineral oil and applied to a cotton-applicator stick. To prevent contact of the liquid odor with the animal, ...

For example, growth hormone deficiency (GHD) during childhood results in growth retardation, as well as abnormal body composition, with more body fat than lean body mass, and decreased physical capacity and quality of life. Growth hormone (GH) treatment has been an established therapy for GHD in...
The metabolome of T-CD and HC children was studied using faecal and urine samples which were analyzed by gas-chromatography mass spectrometry-solid-phase microextraction and 1H-Nuclear Magnetic Resonance. As shown by Canonical Discriminant Analysis of Principal Coordinates, the levels of volatile ...
