甲醇

甲醇（Methanol，或Methyl alcohol；分子式：CH₃OH或MeOH）又称羟基甲烷、木醇（wood alcohol）与木精（wood spirits），是一种有机化合物，为最简单的醇类。「木醇」与「木精」之名源自于甲醇的主要生产方式曾经是萃取自木醋液（为木材干馏或裂解的产物之一）。现代甲醇是直接从一氧化碳，二氧化碳和氢的一个催化作用的工业过程中制备。

甲醇很轻、挥发度高、无色、易燃及有一个独特的气味非常相似乙醇（饮用酒）的气味。但不同于乙醇，甲醇有剧毒，不可以饮用。通常用作溶剂、防冻剂、燃料或变性剂，亦可用于经过酯交换反应生产生物柴油。

Methanol acquired the name "wood alcohol" because it was once produced chiefly as a byproduct of the destructive distillation of wood. Today, industrial methanol is produced in a catalytic process directly from carbon monoxide, carbon dioxide, and hydrogen. 近义、反义、联想词近义词 n. alcohol, fuel 联想词 ethanol乙醇，酒精;acetone丙酮;hydrogen氢;benzene苯;ammonia氨，阿摩尼亚;ethyl乙烷基;aqueous水的，水般的;solvent有溶解力的;urea尿素;biofuel生物燃料;solvents溶剂; 英英词典 methanol n. a light volatile flammable poisonous liquid alcohol; used as an antifreeze and solvent and fuel and as a denaturant for ethyl alcohol synonymous： methyl alcohol, wood alcohol, wood spirit
