氢氧化钾的性质
Properties of potassium hydroxide
白色粉末或片状固体，熔点380 ℃，沸点1324 ℃，相对密度2.04 g/cm3，折射率n20/D 1.421，蒸汽压1mmHg（719 ℃）。其性质与氢氧化钠相似，具强碱性及腐蚀性，0.1 mol/L溶液的pH为13.5。极易吸收空气中水分而潮解，吸收二氧化碳而成碳酸钾。溶于约0.6份热水、0.9份冷水、3份乙醇、2.5份甘油，微溶于醚。当溶解于水、醇或用酸处理时产生大量热量。中等毒，半数致死量（大鼠，经口）1230 mg/kg。
White powder or flake solid, melting point 380 ℃, boiling point 1324 ℃, relative density 2.04 g / cm3, refractive index N20 / D 1.421, vapor pressure 1mmhg (719 ℃). Its properties are similar to that of sodium hydroxide. It is strongly alkaline and corrosive. The pH of 0.1 mol / L solution is 13.5. Easy to absorb moisture in the air and deliquescence, absorption of carbon dioxide and potassium carbonate. It is soluble in about 0.6 parts of hot water, 0.9 parts of cold water, 3 parts of ethanol, 2.5 parts of glycerol, slightly soluble in ether. When dissolved in water, alcohol or treated with acid, a large amount of heat is generated. The median lethal dose (rat, oral) was 1230 mg / kg.

安全措施
Safety measures
皮肤接触：立即脱去污染的衣着，用大量流动清水冲洗至少15分钟。就医。
Skin contact: take off contaminated clothes immediately and rinse with plenty of flowing water for at least 15 minutes. See a doctor.
眼睛接触：立即提起眼睑，用大量流动清水或生理盐水彻底冲洗至少15分钟。就医。
Eye contact: lift eyelids immediately and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. See a doctor.
吸入：迅速脱离现场至空气新鲜处。保持呼吸道通畅。如呼吸困难，给输氧。如呼吸停止，立即进行人工呼吸。就医。
Inhalation: quickly leave the scene to fresh air. Keep respiratory tract unobstructed. If you have difficulty breathing, give oxygen. If breathing stops, give artificial respiration immediately. See a doctor.
食入：用水漱口，给饮牛奶或蛋清。就医。
Ingestion: gargle with water and drink milk or egg white. See a doctor.
灭火方法：用水、砂土扑救，但须防止物品遇水产生飞溅，造成灼伤。
Fire fighting method: use water and sand to put out the fire, but prevent the splashing of articles in contact with water, causing burns.
应急处理：隔离泄漏污染区，限制出入。建议应急处理人员戴防尘面具（全面罩），穿防酸碱工作服。不要直接接触泄漏物。小量泄漏：用洁净的铲子收集于干燥、洁净、有盖的容器中。也可以用大量水冲洗，洗水稀释后放入废水系统。大量泄漏：收集回收或运至废物处理场所处置。
Emergency treatment: isolate the contaminated area and restrict access. It is suggested that the emergency treatment personnel should wear dust masks (full face masks) and acid-base protective clothing. Do not touch the leakage directly. Small leakage: collect with clean shovel in dry, clean and covered container. It can also be washed with a large amount of water and diluted into the waste water system. Large amount of leakage: collect and recycle or transport to waste treatment site for disposal.
