稳定性 | 1.为邻甲酚、间甲酚和对甲酚三种异构体的混合物。化学性质和苯酚相似,有弱酸性,与氢氧化钠作用生成可溶性的钠盐,但不与碳酸钠作用。甲酚钠盐与硫酸二甲酯一类的烷基化剂反应,生成酚醚。与醛类反应得到合成树脂。催化加氢生成甲基环己醇。在温和条件下,甲酚即可进行硝化、卤化、烷基化和磺化反应。甲酚容易氧化,与光和空气接触颜色即变深,生成醌类及其他复杂的化合物。 2.甲酚的异构体中,对甲酚熔点最高,邻甲酚最易挥发。甲酚能与有机碱、有机酸、无机酸、离子等形成各种分子复合物。对金属有腐蚀性。 | ||||||||||||||||
储存条件 | 1.保持贮藏器密封、储存在阴凉、干燥的地方,确保工作间有良好的通风或排气装置。 2.可用镀镍钢、不锈钢或玻璃衬里容器密封阴凉处贮存。 |

Causes skin burns. Prolonged and/or repeated contact may cause irritation and/or dermatitis. Ingestion: Symptoms may include: headache, excitement, fatigue, nausea, vomiting, stupor, and coma. Causes gastrointestinal tract burns. Inhalation: May cause respiratory tract irritation. Chronic: Not available. Section 4 - FIRST AID MEASURES Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Skin: Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. Inhalation: Not available. Notes to Physician: Section 5 - FIRE FIGHTING MEASURES General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Substance is nonflammable. Extinguishing Media: Substance is nonflammable; use agent most appropriate to extinguish surrounding fire. Section 6 - ACCIDENTAL RELEASE MEASURES General Information: Use proper personal protective equipment as indicated in Section 8. Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Wash area with soap and water. Provide ventilation.
