摘要
用水重结晶方法,提纯工业纯的双季戊四醇.采用沸水抽取和离心分离除去杂质的方法,提纯工业纯的三季戊四醇.用示差扫描量热(DS0)法测得提纯的三季戊四醇的熔点为229.9℃.应用热分析方法,测定了双季戊四醇和三季戊四醇的热谱图和二元体系的相图.该体系也是简单低共熔混合物的类型.
The industry reagents of dipentaerythritol and tripentaerythritol were purified by recrystallization in water or by extracting several times with boiling water respectively. The melting point of purified tripentaerythritol was 229.9℃, determined by DSC. Using thermal analysis method, we obtained thermal analysis curves and the binary phase diagram of dipentaerythritol and tripentaerythritol, being simple eutectic system.
