Chemicals in medicines Rakesh Mohan Hallen The words medicine’ and ’drug’ are often used in our country to mean the same substances: any substance‚ manufactured artificially‚ which can help recovery from sickness‚ relieve symptoms or modify a natural process in the body. A medicine is often a mixture of several chemical compounds. Even if it has only one active component compound often other substances are used as fillers or binders to give it bulk.

Potassium Hydroxide (KOH) Introduction Potassium hydroxide is an inorganic compound with the formula KOH‚ commonly called caustic potash. Along with sodium hydroxide (NaOH)‚ this colorless solid is a prototypical strong base. It has many industrial and niche applications. Most applications exploit its reactivity toward acids and its corrosive nature. In 2005‚ an estimated 700‚000 to 800‚000 tonnes were produced. Approximately 100 times more NaOH than KOH is produced annually. KOH is noteworthy

fuels Ex: gasohol‚ a one-to-nine ratio of ethanol and gasoline Simple alcohols – Ethanol ; Poisonous to some extent Examples: Methanol is used for the manufacture of plastics and synthetic fibers. When an –OH group is substituted for one hydrogen atom in ethane‚ the resulting alcohol is ethanol. Ethanol is a good solvent for many organic solutes that cannot dissolve in water. Alcoholic beverages contain ethanol. Gasohol is a mixture of 10% ethanol and gasoline. It is used as a fuel or automobile

The purpose of this experiment was to understand and become familiar with the reaction mechanisms and be able to observe and compare the product or products for each of the reactions using 13C NMR and IR. The reaction of 1-propanol (1a) with NaBr/H2SO4 was 1-bromopropane‚ the reaction of 2-pentanol (1b) with NaBr/H2SO4 was 2-bromopentane
