WebSep 10, 2024 · The adhesive layer preferably has a phenyl group peak area S1 of 0.01 to 3.0 and a carbonyl group peak area S2 of 4.0 or less as measured by Fourier transform infrared spectroscopy (FT-IR). When the peak area S1 of the phenyl group is 0.01 or more and the peak area S2 of the carbonyl group is 4.0 or less, the adhesive layer exhibits more ...

WebOct 1, 2005 · To a solution of 5-acetyl-3-phenyl-1,2,4-triazine 1 (199 mg, 1mmol) [ 3] and 3-nitropyridin-2-ylhydrazine 2 (185 mg, 1.2 mmol) in ethanol (30 ml) 10% HCl (0.5 ml) was added. The resulting reaction mixture was heated at reflux for 5 min and then was stirred at room temperature for 30 min. After that time the solvent was concentrated in vacuo. Webphenyl compounds often can be identified by the pattern in the range 760-690 cm-1, where there is a strong band in the region 700-710 cm-1 and one to three week, medium or strong bands in the region 760-710 cm-1.
