Volatile components from two kinds of Pu-er tea, namely raw tea and ripe tea by two different fermentation processes were extracted by solid phase micro-extraction(SPME) and qual. analyzed by gas chromatog./mass spectrometry (GC-MS). The result showed that 60 volatile compounds were identified from two kinds of Pu-er tea, including 44 from raw tea and 43 from ripe tea and 27 from both of them. The main volatile compounds of raw tea were 1, 2, 3-trimethoxybenzene, epoxylinalool, veratrole, linalool oxide, β-linalool, α-terpineol, etc. The main volatile compounds of ripe tea were 5-methyl-2-hexaone, tetrahydrolinalool, linalool oxide, β-linalool, iso-Bu ether, α-terpineol, etc. There are significant differences among component and content in raw tea and ripe tea on account of fermentation difference. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Application In Synthesis of 2-Butyl-2-ethylpropane-1,3-diol).
2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Application In Synthesis of 2-Butyl-2-ethylpropane-1,3-diol
