摘要
用目视变温法研究了CO(NH_(2))_(2)-C_(3)h_(3)COOH-β-C_(10)H_(7)OH三元有机体系,结果表明:二元固液同组成化合物CO(NH_(2))_(2)·2β-C_(10)H_(7)OH在本三元体系中变成了固液异组成化合物;本三元体系有二个四相平衡不变点,其一是低共熔点:60℃,21.5%CO(NH_(2))_(2)47%C_(6)H_(5)COOH,其二是一转熔点:70℃,13%CO(NH_(2))_(2),40%C_(6)H_(2)COOH(均为重量百分数)。
Ternary orgaaic system urea-β-naphthol——benzoic acid was studted by visual polythermal method,experimental results show:congruently melting compound CO(NH_(2))_(2).2β-C_(10)H_(7)OH changes into incongruently melting compound,there aretwo quadruple poiuts in this ternary system,the one is at 60°C,21.5%CO(NH_(2))_2,47%C_(6)H_(5)COOH,the Other is at 70°C,13%CO(NH_(2)_(2))40%C_(6)H_(2),COOH.
