Özet:

 In this study, content analyses of the products obtained by pyrolysis and extraction of walnut shells were performed with some advanced analytical methods such as GS-MS, LCMS-MS, and FTIR. In LC-MSMS analyses. The presence of phenolic compounds in the pyrolysis liquid and extract liquid of walnut shells was determined using 41 standards. The obtained LC-MSMS analysis results were compared, and it was found that the type and amount of phenolic compounds in the extracted liquid were more than the type and amount of phenolic compounds in the pyrolysis liquid. As a result of 41 phenolic standards investigations, the presence of a total of 10 phenolic compounds in liquids was detected and 2 of these compounds were detected in the pyrolysis liquid and 8 in the extracted liquid. As phenolic compounds, catechin 770.75 µgg extract, hydroxy benzaldehyde 140.78 µgg extract, and vanillic acid 114.95 µgg compounds were detected in the walnut extract. The existence of the compounds was supported by FTIR analyses of liquids obtained as a result of two different processes. By GC-MS analysis, linoleic acid methyl ester 44.01, stearic acid methyl ester 14.93, palmitic acid methyl ester 24.67, linolenic acid and methyl ester compounds were detected in walnut shell extract liquid. GC-MS analysis of the pyrolysis liquid showed that compounds such as stearic acid methyl ester 18.97, palmitic acid methyl ester 18.10, o-xylene 12.17, and o-ethyl toluene 8.14 were formed as a result of pyrolysis. The findings revealed that walnut shell pyrolysis liquid product and extract contain very different phenolic, acid, and ester compounds. A concrete result was revealed about the use of the products obtained in this study in different areas.
