Previous investigations have shown that the type and the quantity of tertiary amine influence the properties of restorative resins. It was the purpose of the present work to analyze qualitatively and quantitatively the amines in commercial restorative resins. The amines were extracted with hydrochloric acid from chloroform solutions of the monomers. For the qualitative analysis the acid amine solution was made alkaline, the amine extracted with methylenechloride and isolated. The method of analysis was NMR-spectroscopy. The quantitative determination was performed by means of UV-spectra of the acid amine solutions. Sixteen brands were investigated, and three species of amine were identified. The amount of amine varied between 0.3% and 4% by weight of the monomer. Iit is probable that the information obtained will lead to a better understanding of the nature of restorative resins.
先前的研究表明，叔胺的类型和数量会影响修复性树脂的性能。本研究的目的是对市售修复性树脂中的胺进行定性和定量分析。胺从单体的氯仿溶液中用盐酸萃取。进行定性分析时，将酸性胺溶液碱化，用二氯甲烷萃取并分离出胺。分析方法为核磁共振光谱法。通过酸性胺溶液的紫外光谱进行定量测定。研究了16个品牌，鉴定出三种胺。胺的含量在单体重量的0.3%至4%之间。所获得的信息可能会有助于更好地理解修复性树脂的性质。
