震惊全国的山西假酒案,触目惊心。现根据技术监督部门质量检验机构提供的资料和数据,介绍一点关于“甲醇”的知识。甲醇同乙醇(酒精)一样同属含羟基类有机化合物,其分子式是CH_3OH,俗名木醇、木精,带有酒精的气味,剧毒。甲醇在体内分解缓慢,并有一定的蓄积作用,视神经对甲醇的毒性作用很敏感。中毒剂量个体差异很大,若饮用5克以上可引起失明,饮用10克以上可致死亡。日常饮用的白酒中有甲醇吗?对人体是否有害?按国家有关标准规定,白酒允许含有甲醇的
The Shanxi counterfeit wine case that shocked the country was shocking. According to the information and data provided by the quality inspection agency of the technical supervision department, we will introduce a bit of knowledge about methanol. Methanol and ethanol (alcohol) are both hydroxy-containing organic compounds. Its molecular formula is CH_3OH, which is commonly known as wood alcohol and wood essence. It has the smell of alcohol and is highly toxic. Methanol decomposes slowly in vivo and has a certain accumulation effect. The optic nerve is very sensitive to the toxic effects of methanol. Poisoning doses vary widely among individuals. If drinking more than 5 grams can cause blindness, drinking more than 10 grams can cause death. Is there any methanol in the daily drinking spirits? Is it harmful to the human body? According to the relevant national standards, liquors are allowed to contain methanol.
