dc.description.abstract	本研究以酮類化合物與硫尿及碘反應合成五種2-胺基噻吖唑衍生物，並藉由其IR光譜圖來討論各官能基於圖譜上顯示之吸收峰來判斷此類化合物之形成。以2-胺基-4-苯基-1,3-噻吖唑為原料，該化合物之胺基重氮化與二甲基苯胺及γ酸偶合為偶氮染料，也與對二甲基胺苯甲醛在酸性乙醇下反應為吖次甲基染料兩大類。將所合成之染料與苯系染料比較，觀察其可見光譜之最大吸收波長之異同，所得結果噻吖唑系都有紅移現象。其中偶氮染料系在酸性溶液中紅移3~ 77 nm；在鹼性溶液中有沉澱現象，因此有些不能比較；吖次甲基類染料則紅位移波長達267及237 nm。	zh_TW
dc.description.abstract	The five derivatives of 2-aminothiazoles were obtained by reacting with ketone compounds and thiourea, iodine, and identified these com- pound with their several functional groups absorption peak of the IR spectra. Synthesis azo dyes were synthesized from amine of the 2-amino- 4-phenyl-1,3-thiazole diazotize to coupling with N,N-dimethylaniline or gamma acid, also reacted with the 4-Dimethylaminobenzaldehyde to form the azamethine dyes in the acid ethanol solution. Compare and observe the difference between thaizole’s dyestuffs and benzene’s dyestuffs there maximum of the absorptive wavelengths of the visible light, the result of the thaizole’s dyestuffs has been shown the bathochromic shift effect be- tween 3~77 nm in the acid solution, there is phenomenon of precipitating in the base solution, so some can’’t compare; but azamethine dyestuffs ba- thochromic shift 267 and 237 nm.	en_US
