The aim of this experiment was to analyze the leaf volatiles of crabapple (Malus sp.) individuals at different juvenile lengths, and obtain their particular leaf volatiles, and provide reference for finding out a new breeding method. Volatiles of leaves from eight different crabapple individuals were evaluated with the method of head space-solid phase micro-extraction and gas chromatog.-mass spectrometry (HS-SPME-GC-MS). Volatiles profiles of them were then compared. Eighty-four kinds of volatiles were detected with varied contents found in different individuals. The major leaf volatiles were 2-fluoro-acetamide, (Z)-3-Hexen-1-ol, di-Et phthalate and (Z)-3-Hexen-1-ol acetate. Ten identical compositions including 3,7-dimethyl-1,3,7-octatriene, decanal, di-Et phthalate, 2,6,10-trimethylpentadecane, 2,6,10-1-tetradecanol; 2,6,10,14-tetramethyl pentadecane, hexadecane, 1-dodecanol; 2,6,10,15-tetramethyl heptadecane and Phthalic acid, diisobutyl ester were detected. Leaf volatiles differ in eight crabapple individuals. But they are all based on esters and hydrocarbons and the highest content is 3-Hexen-1-ol, acetate. The specific volatiles in the precocious crabapple are (2Z)-2-Penten-1-ol, acetate (E)-cyclobutane, 1,3-butadienyl and 5,5-dibutylnonane. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Quality Control of 2-Ethylhexyl benzoate).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Quality Control of 2-Ethylhexyl benzoate
