苯酚+乙腈二元系固液相平衡

Solid and Liquid Phase Equilibrium in Phenol with Acetonitrile

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) .

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.
