    硼酸

    硼酸

    基本信息

    • 分子式: B(OH)₃
    • CAS号: 7636-18-8
    • 结构式: 由一个硼原子和三个羟基(-OH)组成，呈三角锥形结构。

    物理性质

    • 外观: 白色粉末或结晶固体。
    • 熔点: 纯品的熔点为100.3°C（含微量水时降低至77.5°C）。
    • 溶解性: 易溶于水，略溶于乙醇。

    化学性质

    • 酸性: 能够与碱反应生成硼酸盐，并释放出氢氧根离子，表现出弱的两性。
    • 反应活性: 与其他含羟基或活泼氢的化合物发生酯化、酰化等反应。在有机合成中，作为催化剂用于某些反应过程。

    应用领域

    1. 医药: 用于制备其他药物成分，如硼酸钠，应用于治疗皮肤疾病及作为防腐剂。
    2. 化工: 制造各种化学品的基础原料，包括农药、塑料添加剂等。
    3. 分析化学: 作为一种缓冲溶液或pH调节剂使用。

    安全注意事项

    • 硼酸对人体具有一定的毒性。如果误食可能导致消化道灼伤，长期接触可引起皮肤刺激反应。
    • 使用时应穿戴适当的防护装备，并避免吸入其粉尘和蒸汽。

    请注意，在实际应用中需要严格遵守相关安全规范及操作指南以确保人员安全与健康。
