How It Is Synthesized Methamphetamine was first synthesized from ephedrine in Japan in 1893 by chemist Nagai Nagayoshi. In 1919‚ crystallized methamphetamine was synthesized by Akira Ogata via reduction of ephedrine using red phosphorus and iodine. Synthesis is relatively simple‚ but entails risk with flammable and corrosive chemicals‚ particularly the solvents used in extraction and purification; therefore‚ illicit production is often discovered by fires and explosions caused by the improper

Solubility in Water and Density All the haloalkanes are insoluble in water but there are soluble in organic solvent. All haloalkanes expect bromoalkanes and iododalkanes are denser than water. Reaction of haloalkane with ammonia Will form amine RNH2 and NH3 in the nucleophile.Example‚ bromoethane (CH3CH2Br) react with NH3 and produce (CH3CH2NH2) ethanamine. CH3CH2Br + 2NH3 Reaction of haloalkane with with Sodium Hydroxide (NaOH) Will form alcohol and OHˉion is the nucleophile

Around 30% of glucose consumed is used by the brain‚ which does rely primarily on glucose for energy. If the brain is not getting enough glucose‚ a person can feel tired and cranky because their brains are receiving too little energy. 3. If the amine group is broken off and discarded‚ this creates nitrogenous waste in the blood that the kidneys must remove and discard in the urine. The remaining carbon chain can be metabolized‚ or used to build fatty acid chains for energy storage. While most low-carb

Poultry or beef? Which meat is healthier for us to eat? Due to the importance that society today has put on our health due to health consequences and prices differences I am choosing to compare and contrast poultry and beef. Although many of us may think that chicken is so much healthier then beef‚ I will show to you that each of the meats have their own good and bad purposes in or healthy lifestyle habits. For me it all started about two years ago when my best friend was in the emergency room

Detergents A detergent is a surfactant or a mixture of surfactants with "cleaning properties in dilute solutions."[1] These substances are usually alkylbenzenesulfonates‚ a family of compounds that are similar to soap but are more soluble in hard water‚ because the polar sulfonate (of detergents) is less likely than the polar carboxyl (of soap) to bind to calcium and other ions found in hard water. In most household contexts‚ the term detergent by itself refers specifically to laundry detergent
