Determination of water soluble organic compounds in Arctic aerosols by capillary GC and GC/MS was written by Kasukabe, Hideki;Kawamura, Kimitaka;Barrie, Leonard A.. And the article was included in Bunseki Kagaku in 1994.Recommanded Product: 1190-39-2 This article mentions the following:
Water soluble organic compounds in Arctic aerosol samples were analyzed by using GC/MS. The carboxyl and aldehyde groups in the bi-functional compounds were derivatized with 14% BF3/BuOH to di-Bu ester and di-Bu acetal, resp. The results showed that oxalic (C2) acid was the dominant species (1.8-70 ng/m3) followed by malonic (C3) and succinic (C4) acid in all samples, in July 1987-June 1988. Total concentrations of dicarboxylic acids were 4.3-97 ng/m3 and showed seasonal variation with a maximum at Arctic sunrise. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Recommanded Product: 1190-39-2).
malonic acid dibutyl ester (cas: 1190-39-2) 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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is 绾?valerolactone.Recommanded Product: 1190-39-2
