“…This procedure has been applied to analysis of resinite samples by Py-MS (14) but has not previously been used in conjunction with Py-GC/MS for the analysis of resinite samples. Low-temperature (injection port) pyrolysis of the tetramethylammonium salts of diterpenoid "resin acids", and other carboxylic acids, is known to generate the corresponding methyl esters in high yield (23,24), but the effects of copyrolysis with TMAH at higher temperatures on the structures of resin acid methyl esters (RAMES), many of which contain potentially sensitive olefinic structures, are unknown. The purpose of the present study, therefore, was to assess the scope and potential limitations of Py-GC/MS, for the structural analysis of resins and resinites based on diterpenoid carboxylic acids and to evaluate the effects of SPM procedures on the product distributions observed in such experiments.…”

The application of pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) to the analysis of natural resins and resinites based on dlterpenold carboxylic acids has been Investigated, In order to determine the usefulness of this technique for the analysis of these materials. It has been found that Py-GC/MS analyses using simultaneous pyrolytic methylation (SPM) provide an accurate Indication of the composition of these materials, except with respect to compounds with an additional hydroxy and/or carbonyl functionality. Resin acid methyl esters (RAMES) are efficiently produced In situ by copyrolysls with tetramethylammonlum hydroxide. Pyrolysis did not result In significant thermal degradation or Isomerization of the RAMES characterized In this study. Some dehydration of RAME alcohols Is observed however, and both hydroxy-and carbonyl-containing RAMES undergo undesirable side reactions with the methylating reagent, which results In the formation of nitrogen-containing products. The optimum pyrolysis temperature for low-to moderate-rank resinites using the conditions employed In this study was found to be 480 °C. Py-GC/MS analyses without In situ methylation were found to provide generally less adequate data for structural and compositional analyses.

“…One technique which avoids the disadvantages of conventional solvent extraction is to methylate the sample directly within the gas chromatograph (GC) using a tetraalkylammonium hydroxide derivative (see review by Kossa et al 1979). A variety of sample types and compound classes have been examined using these reagents, including diterpene and triterpene acids, fatty acids, triacylglycerols, waxes, proteins and kerogen (e.g., Hetman et al 1965;MacGee 1968;Joye et al 1974;Kossa et al 1979;Challinor 1991aChallinor , 1991bChallinor and 1993. Tetramethylammonium hydroxide (TMAH) is the most widely reported reagent for such derivatization (Kossa et al 1979).…”

A Comparison of Methods for Establishing Fatty Acid Concentration Gradients Across Potsherds: A Case Study Using Late Bronze Age Canaanite Amphorae*

Canaanite amphorae fragments in fabrics believed to be associated with the bulk transport of vegetable oils from the fourteenth‐century BC site of Amarna, Egypt, have been examined. A comparison is made between solvent extraction, saponification and the use of TMTFTH (m‐trifluoromethylphenyl)trimethylammomum hydroxide, used here for the combined extraction and derivatization of ceramic‐absorbed organic residues. Extracts were studied using gas chromatography and gas chromatography‐mass spectrometry. The extraction of fatty acids from small ceramic samples has established concentration gradients of absorbed organic matter from the inner to the outer surfaces of the sherds.

“…Tall oil rosin is a product of tall oil distillation. It consists of abietic and pimaric acids [1][2][3][4][5][6][7][8] and is used in various industries [7,8]. The main products based on tall oil rosin are potassium and sodium salts and glycerol and pentaerythritol esters of the acids [8].…”
