其他信息
- MOL 文件:288-32-4.mol
- 用途四:咪唑类主要用作环氧树脂的固化剂,在日本占咪唑类消费量的一半以下,其用量为环氧树脂的0.5%-10%咪唑类化合物可用作抗真菌药、抗霉剂、低血糖治疗药、人造血浆等,还可用作治疗、人造血浆等,还可用作治
- 用途三:咪唑是农药抑霉唑、咪鲜胺等杀菌剂的中间体,也是医药抗真菌药双氯苯咪唑、益康唑、酮康唑、克霉唑的中间体。
- 主要用途:咪唑可用作环氧树脂固化剂、可提高制品的弯曲、拉伸、压缩等机械性能,提高绝缘的电性能,提高耐化学药剂的化学性能,广泛用于计算机、电器; 作为铜的防锈剂而用于印刷电路版和集成电路; 用作医药原料,用于制造抗真菌药、抗霉剂、低血糖治疗药、人造血浆、滴虫治疗药、支气管哮喘治疗药、防斑疹剂等; 用作农药原料,用于硼酸制剂的增效剂、制取杀虫剂和杀菌剂; 此外,咪唑也用作脲醛树脂固化剂、摄影药物、粘合剂、涂料、橡胶硫化剂、防静电剂等的原料; 有机合成中间体。
- 物理性质:自然界只存在咪唑衍生物,而无游离的咪唑。从苯中析出者为单斜晶系棱柱状无色结晶。有氨气味。相对分子质量68.08。相对密度1.0303(101/4℃)。熔点89~91℃,沸点257℃、165℃~168℃(2.67×103Pa)、138.2℃(1.60×103Pa)。闪点145℃。折射率1.4801(101℃)。粘度2.696mPa·s(100℃)。微溶于苯、石油醚,溶于乙醚、丙酮、氯仿、吡啶,易溶于水(常温70)、乙醇。显弱碱性。因为1位的—NH—键和3位上的—N=键之间形成氢键,所以沸点较高,当1位氢被取代后,则不能形成氢键,沸点下降。对热稳定,在250℃以下几乎不分解(分解温度590℃)。对还原剂和氧化剂也很稳定,但可以和无机酸形成稳定的盐。具有芳香族的某些性质,可以在催化剂作用下卤化、硝化、磺化及羟甲基化。并可以和重氮盐在2位偶合。此外,由于=NH基(1位)连接两个双键,又有些“酸性”,可以被金属取代而生成盐。3位氮原对金属离子有配位作用,可形成螯合物。虽然很难被还原,但可以和质子加合生成阳离子型且有共振的结构,而形成稳定的形态。咪唑环的互变异构体之间极易变化,所以4位和5位的异构体不易区别。 以上信息由Chemicalbook的Andy编辑整理。
