【摘要】 全浓度范围内测定了 x C6H5OH+(1 -x) CH3CN二元系固液平衡相图 ,此体系形成了摩尔比 1∶ 3的不稳定化合物 CH3CN· (C6H5OH) 3,其转熔温度为 2 80 .55K,体系低共熔点组成和温度分别为 x=0 .1 47,T=2 2 1 .2 8K.转熔点位置在 (0 .72 8,2 80 .55K) .可认为化合物是由于苯酚中的羟基氢原子与乙腈中的氮原子通过氢键作用而成更多还原

【Abstract】 Solid+liquid) phase diagram have been constructed for phenol+acetonitrle. An inconguently melting solid addition compound from with the empirical formulae:CH 3CN·(C 6H 5OH) 3. The peritectic is at x=0.728,and T=280.55K. A eutectic is atx=0.147 and T=221.28K. Compound formation is attributed to hydrogen bonding between hydroxyl hydrogens in phenol and nitrogens in acetonitrile.更多还原
