甲基苯丙胺和盐酸之间的区别

甲基苯丙胺 vs. 盐酸

基苯丙胺或甲基安非他命（英語：Methamphetamine，全名是)）是強效的中樞神經系統刺激劑，主要被用於娛樂用途，較少被用於治療注意力不足過動症和肥胖症，即便有也被當成第二線療法。甲基苯丙胺是在1893年發現，有二種对映异构：分別是左旋甲基苯丙胺（levo-methamphetamine）及右旋甲基苯丙胺（dextro-methamphetamine）。「甲基苯丙胺」一般是指左旋甲基苯丙胺及右旋甲基苯丙胺各佔一半的外消旋混合物。甲基安非他命較少被醫師處方，因為可能會，以及有用作春藥和欣快感促進劑等風險。而且已有療效相同，而對人體危害風險更低的替代藥物。 在美國能直接在市面上購買主成分為左旋甲基苯丙胺的吸入型因為它被視為非处方药。 甲基苯丙胺常因為它們的藥效動力學屬性而被非法交易，用於娛樂用途。非法使用甲基苯丙胺在亚洲部分地区、大洋洲和美国最为普遍。在美国，消旋以及左旋、右旋甲基苯丙胺均为。 Levomethamphetamine is available as an over-the-counter (OTC) drug for use as an inhaled in the United States. Internationally, the production, distribution, sale, and possession of methamphetamine is restricted or banned in many countries, due to its placement in schedule II of the United Nations Convention on Psychotropic Substances treaty. While dextromethamphetamine is a more potent drug, racemic methamphetamine is sometimes illicitly produced due to the relative ease of and limited availability of chemical precursors. In low doses, methamphetamine can elevate mood, increase alertness, concentration and energy in fatigued individuals, reduce appetite, and promote weight loss. At higher doses, it can induce, breakdown of skeletal muscle, and bleeding in the brain. Chronic high-dose use can precipitate unpredictable and rapid s, (e.g., paranoia, hallucinations, delirium, and delusions) and violent behavior. Recreationally, methamphetamine's ability to has been reported to lift mood and increase sexual desire to such an extent that users are able to engage in sexual activity continuously for several days. Methamphetamine is known to possess a high addiction liability (i.e., a high likelihood that long-term or high dose use will lead to compulsive drug use) and high dependence liability (i.e. a high likelihood that withdrawal symptoms will occur when methamphetamine use ceases). Heavy recreational use of methamphetamine may lead to a, which can persist for months beyond the typical withdrawal period. Unlike amphetamine, methamphetamine is to human midbrain neurons. It has also been shown to damage serotonin neurons in the CNS. This damage includes adverse changes in brain structure and function, such as reductions in grey matter volume in several brain regions and adverse changes in markers of metabolic integrity. Methamphetamine belongs to the and. It is related to the other s as a positional isomer of these compounds, which share the common chemical formula:. 酸，學名氢氯酸（hydrochloric acid），是氯化氢（化学式：HCl）的水溶液，属于一元无机强酸，工业用途广泛。盐酸为无色透明液体，有强烈的刺鼻味，具有较高的腐蚀性。浓盐酸（质量百分濃度约为37%）具有极强的挥发性，因此盛有浓盐酸的容器打开后氯化氢气体会挥发，与空气中的水蒸气结合产生盐酸小液滴，使瓶口上方出现酸雾。盐酸是胃酸的主要成分，它能够促进食物消化、抵御微生物感染。 16世纪，利巴菲乌斯正式记载了纯净盐酸的制备方法：将浓硫酸与食盐混合加热。之后格劳勃、普利斯特里、戴维等化学家也在他们的研究中使用了盐酸。 工业革命期间，盐酸开始大量生产。化学工业中，盐酸有许多重要应用，对产品的质量起决定性作用。盐酸可用于酸洗钢材，也是大规模制备许多无机、有机化合物所需的化学试剂，例如聚氯乙烯的前体氯乙烯。盐酸还有许多小规模的用途，比如用于家务清洁、生产明胶及其他食品添加剂、除水垢试剂、皮革加工。全球每年生产约两千万吨的盐酸。.

化学式

化學式（chemische Formel／chemical formula），是一種用來表示化學物質（也可能為元素或化合物）組成的式子。 一般情況下，由元素符號、數字或其他符號組成；這些符號單一行列，被限制在一個排版，並會出現上標和下標。 下為常用符號：.

前体

在化学领域，前体是一种可以参与化学反应的化学物质，其反应结果是生成另一种化学物质。一个简单的例子是，甲烷可称作一氯甲烷的前体。在生物化学领域，“前体”这一名词，更为特别的应用于描述代谢途径的物质转化。例如，在糖酵解过程中，葡萄糖可称作葡萄糖-6-磷酸的前体。.
