Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about SPME-GC-MS analysis of volatile components in fruits of the frozen Ficus tikoua Bur..Quality Control of 1-Iodo-2-methylbutane.
This thesis developed an SPME-GC-MS method for the aroma components in Ficus tikoua Bur. fruit. At the same time, the solid-phase micro extraction conditions were optimized: extraction temperature was 50°C, the extraction time was 40 min, added 8 g of sodium chloride electrolyte solid extraction Frozen Ficus tikoua Bur. fruit was detected out of 152 kinds of volatile substances, substances detected in 99.03%of the total. The main aroma components were esters, accounting for 33.06%; alcs., accounting for 13.14%; alkanes, accounting for 13.18%; there ketones, aldehydes, acids and other substances. Higher levels of 10 kinds of aroma components were guaiacol (14.71%), cyclobutane carboxylic acid dodecyl ester (13.54%), n-tridecane (6.05%), 2-tridecanone (4.72%), cyclohexasiloxane (4.44%), cyclobutane carboxylic acid decyl ester (4.18%), Me nonyl ketone (3.62%), acetic acid (2.98%), cyclopentanecarboxylic acid thirteen ester (2.48%), 2-tetradecanol (2.31%) and so on.
When you point to this article, it is believed that you are also very interested in this compound(616-14-8)Quality Control of 1-Iodo-2-methylbutane and due to space limitations, I can only present the most important information.
