  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.

  Novel pyrethroid intermediates ##STR1## wherein R.sup.1 and R.sup.2 each is alkyl are prepared by treating 2,2-dimethyl-3-(2-oxopropyl)cyclopropylacetaldehyde with a trialkylsilyldialkylamine. The above compounds can be treated with ozone to form 2,2-dimethyl-3-(2-oxopropyl)cyclopropanecarbaldehyde.
