  Identification of Products Containing −COOH, −OH, and −CO in Atmospheric Oxidation of Hydrocarbons

  摘要：

  Atmospheric oxidation of hydrocarbons by hydroxyl radicals and ozone leads to products containing -COOH, -OH, and -C=O functional groups. The high polarity of such compounds precludes direct GC-MS analysis. In addition, many such compounds often exist in a single sample at trace levels. An analytical method has been developed to identify compounds containing one or more functional groups of carbonyl, carboxy, and hydroxy in atmospheric samples. In the method, -C=O groups are derivatized using 0-(2,3,4,5,6-pentafluorobenzyl) hydroxy amine (PFBHA), and -COOH and -OH groups are derivatized using a silylation reagent N,O-bis(trimethylsilyl)trifluoro-acetamide (BSTFA). The derivatives are easily resolved by a GC column. The chemical ionization mass spectra of these derivatives exhibit several pseudomolecular ions, allowing unambiguous determination of molecular weights. Functional group identification is accomplished by monitoring the ions in the electron ionization mass spectra that are characteristic of each functional group derivative: m/z 181 for carbonyl and m/z 73 and 75 for carboxyl and hydroxy groups. The method is used to identify products in laboratory studies of ozone oxidation of alpha-pinene and Delta(3)-carene. Among products from ozone oxidation of alpha-pinene, we have detected pinonaldehyde, norpinonaldehyde , pinonic acid, norpinonic acid, C-10 hydroxy dicarbonyls, pinic acid, 2,2-dimethyl-3-(formylmethyl)-cyclobutane-formic acid, and a product that has a molecular weight of 156 and contains a C=O and a COOH/OH group. The latter two products have not been reported previously. Delta(3)-carene is structurally analogous to alpha-pinene in that both have an internal unsaturated bond where ozone oxidation takes place. We have also identified the corresponding analogous products, of which all but caronaldehyde are reported for the first time.

  臭氧氧化环状单萜产生的二次气溶胶中的羧酸

  摘要：

  已经进行了一系列烟雾室实验，其中五种环状单萜被臭氧氧化。通过 GC-MS 和 HPLC-MS 分析释放的二次气溶胶中的非挥发性极性氧化产物，重点是羧酸的鉴定。在对应于低百分比摩尔产率的浓度水平下测定了三类化合物：即二羧酸、氧代羧酸和羟基酮羧酸。羧酸具有高极性，并且比其相应的醛具有更低的蒸气压，因此可能在二次有机气溶胶形成过程中发挥重要作用。最丰富的羧酸如下：来自α-和β-蒎烯的顺式松香酸AB1（顺式-3-羧基-2,2-二甲基环丁基乙酸）；cis-pinonic acid A3 (cis-3-acetyl-2, 来自α-蒎烯和β-蒎烯的2-二甲基环丁基乙酸）和顺-10-羟基松香酸AB6（顺-2,2-二甲基-3-羟基乙酰环丁基乙酸）；cis-3-caric acid C1 (ci...

  Carboxylic acids are highly polar and have lower vapor pressures than their corresponding aldehydes and may thus play an important role in secondary organic aerosol formation processes. The most abundant carboxylic acids were the following:  cis-pinic acid AB1 (cis-3-carboxy-2,2-dimethylcyclobutylethanoic acid) from α- and β-pinene; cis-pinonic acid A3 (cis-3-acetyl-2,2-dimethylcyclobutylethanoic acid)
