能形成亚硫酸氢盐的加成化合物。能与乙醇和乙醚混溶，微溶于水，水中溶解度: 20g/L (20°C) 。 2-己酮（MBK，2-氧代己烷）是一种挥发性有机化合物，以无色透明的液体形式存在，具有浓烈的气味。它极易溶于水，并很容易以蒸气的形式蒸发到空气中。偶尔发现它是正常人生物流体的挥发性成分。它曾被用作工业六碳碳溶剂，但由于其神经毒性导致各种人类疾病而不再使用或制造。 应用 2-己酮可用作分析标准品，用于通过各种色谱技术测定生物样品、淀粉基聚合物、发霉的建筑材料和酒精基质中的分析物。 2-Hexanone (MBK, 2-Oxohexane) is a volatile organic compound, that exists as a clear, colorless liquid with a sharp odor. It dissolves very easily in water, and can evaporate easily into the air as a vapor. It is occasionally found as a volatile component of normal human biofluids. It was used as an industrial hexacarbon solvent, but is no longer used or made owing to its neurotoxic nature leading to various human diseases.
