Aspartame has been proven to be 160 to 220 times sweeter then real sugar This synthetic chemical is commonly known as NutraSweet or Equal. Over half of the U.S. population currently consumes it. Aspartame came onto the market in 1981‚ and has accounted for more then half of all the complaints that the FDA receives each year. Aspartame was accidentally discovered in 1965 by a chemist trying to develop an ulcer drug. The FDA earlier then 1981 did not approve it because it had been tested with

Tuesday‚ February 19‚ 2013‚ Shop-C section of the Westbury factory was destroyed due to the massive chemical plant explosion caused by some of the workers’ negligence. According to the company‚ the chemical methanol was being unloaded from a rail-car when the explosion occurred. Methanol is a highly flammable‚ toxic‚ wood alcohol. American citizen Jessica Lee says 108 people were killed‚ 200 were injured‚ and over 50 of them lost their eyes. “My husband was there when the explosion happened

Isolation of the active ingredient in an Analgesic Drug from extraction‚ filtration and melting point. Chm237 Abstract: Acetaminaphen was crushed then extracted for the active ingredient by mixing it with methanol. Then separated from the binders by centrifugation and a filtration technique using a Pasteur pipet packed with alumina. The remaining solvent was then evaporated to yield the solid analgesic(.2295g‚ 45.9% yield) which was collected by filtration and tested for the

formalin. The commercially available formalin has 10 to 12% methanol with a few impurities like aluminum and copper. Almost 21 million tonnes of formaldehyde is produced annually all around the world. Synthesis of Formaldehyde Formaldehyde is produced by catalytic oxidation of methanol. A mixture of molybdenum and iron or silver is used as a catalyst in such a reaction. But a more commonly used process is FORMAX. In this process‚ methanol and oxygen react at temperatures more than 250ºC in presence

The following compounds are found in embalming fluid‚ formaldehyde‚ methanol‚ and ethanol or ethyl alcohol. In embalming fluid products‚ the percentage of formaldehyde can range from 5 to 29 percent; ethyl alcohol content can vary from 9 to 56 percent. Ethyl alcohol is also a central nervous system depressant. The drug

Methanol- Yes or No? Do you agree on building the world’s largest methanol plant in Tacoma‚ WA? Many people disagree‚ because the negative impacts far outweigh the positive ones. One negative impact is the plant would take up too much resource. In addition to that‚ the methanol plant will also change the environment. Here is how the two negative points can affect the world today. The first negative impact is the methanol plant will take a lot of resources. One detail to support the claim in “Redline

Lab 3: Crystallization Report Objective: the objective of this lab is to introduce the technique of crystallization. Background: The chemicals used in part A were Sulfanilamide and Ethyl alcohol. Sulfanilamide(C6H8N2O2S)‚ or sulfonamide antibiotic‚ functions by competitively inhibiting enzymatic reactions involving para-aminobenzoic acid (PABA). PABA is needed in enzymatic reactions that produce folic acid which acts as a coenzyme in the synthesis of purine‚ pyrimidine and other amino acids
