环己醇在常压下的沸点是多少

环己醇化学品英文名称：cyclohexanol，化学式：C6H12O，分子量：100.16，外观与性状：无色、有樟脑气味、晶体或液体。熔点（℃）：25.2，沸点（℃）：160.9，相对密度（水=1）：0.9624，相对蒸气密度（空气=1）：3.45，饱和蒸气压（kPa）：0.13（21℃），燃烧热（kJ/mol）：890.7，闪点（℃）：67，引燃温度（℃）：300，折光率：1.465，环己醇微溶于水，可混溶于乙醇、乙醚、苯、乙酸乙酯、二硫化碳、油类等。

甲酸在多少温度下挥发

因为甲酸的沸点是100.6℃。那么温度超过100.6℃时，甲酸就会挥发。

甲酸是一种有机物，化学式为HCOOH，分子量46.03，俗名蚁酸，是最简单的羧酸。甲酸沸点100.6℃，闪电69℃，密度为1.22 g/cm³。

甲酸易燃。能与水、乙醇、乙醚和甘油任意混溶，和大多数的极性有机溶剂混溶，在烃中也有一定的溶解性。

甲酸相对密度1.220。折光率1.3714。燃烧热254.4 kJ/mol，临界温度306.8 ℃，临界压力8.63 MPa。闪点68.9 ℃（开杯）。密度1.22g/cm3，饱和蒸气压（24℃）5.33 kPa。

甲酸为强的还原剂，能发生银镜反应。在饱和脂肪酸中酸性最强，离解常数为2.1×10-4。在室温慢慢分解成一氧化碳和水。与浓硫酸一起加热至60~80℃，分解放出一氧化碳。甲酸加热到160℃以上即分解放出二氧化碳和氢。甲酸的碱金属盐加热至400℃生成草酸盐。

甲酸是唯一能和烯烃进行加成反应的羧酸。甲酸在酸的作用下（如硫酸，氢氟酸），和烯烃迅速反应生成甲酸酯。但是类似于Koch反应的副反应也会发生，产物是更高级的羧酸。
