Comparative analysis of eastern and western drying-oil binding media used in polychromic artworks by pyrolysis-gas chromatography/mass spectrometry under the influence of pigments was written by Wang, Na;He, Ling;Zhao, Xiang;Simon, Stefan. And the article was included in Microchemical Journal in 2015.Product Details of 106-79-6 This article mentions the following:
The mostly used drying-oils as binding media in historical artworks of eastern tung-oil and western linseed-oil, poppy-oil, walnut-oil are comparatively identified by online methylated pyrolysis-gas chromatog./mass spectrometry (Py-GC/MS). Based on the anal. of un-pigmented and pigmented reference samples after treated by natural aging, hydro-thermal aging and UV aging, resp., the characteristic pyrolysis products of all drying-oils are classed into mono-carboxylic acids (C6-8, 14, 16, 18, 20), di-carboxylic acids (2C6-12), glycerol, erythritol, 2-tridecanone, 8-hydroxy-octanoic acid, 3-octyl-oxiraneoctanoic acid and 2,6,10-trimethyl-9-undecenoic acid. Both benzene derivative and 9,10-dihydroxy-octadecanoic acid are suggested as the marked components for distinguishing eastern and western drying-oil. The investigated pigments of malachite, cinnabar, azurite and ochre do not show obvious influence on the detection of characteristic pyrolysis products of drying-oil, but they are proved to accelerate the aging and hydrolyzing rate of drying-oil, especially the pigment of cinnabar. The established online methylated Py-GC/MS procedure and the summarized data have been successfully applied on the identification of raw tung-oil and boiled tung-oil in historical painting samples collected from Drum Tower (Ming Dynasty), Bell Tower (Ming Dynasty), and Thousand-Buddha Cliff Grotto (Tang Dynasty). It is believed that the established Py-GC/MS procedure is able to provide wide application in archeol. research. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Product Details of 106-79-6).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Product Details of 106-79-6
