Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol

Goodpasture’s syndrome (GS) is a rare disease‚ identified by Dr. Ernest Goodpasture in 1919 He described the syndrome during the influenza pandemic of 1919 when he reported on a patient who died from bleeding in the lungs and kidney failure. The incidence of Goodpasture is estimated to 1 case per million per year. This disease occurs more commonly in white people than in black people and is widespread in men than in women. Goodpasture syndrome is a pulmonary-renal syndrome‚ which is a group of acute

molecules can participate in as well due to the transient dipole moments that exist in them. In the solid-liquid extraction‚ a solvent is added to a mixture of solid compounds. A specific compound in the mixture will dissolve in that solvent. Vacuum filtration can then be used to separate the specific compound from the other compounds in the mixture‚ which are insoluble in that solvent. In the liquid – liquid extraction‚ you must have solvents that are immiscible (organic and aqueous). The solvents do

To extract the benzocaine‚ 6 M of sodium hydroxide was added and the solution was filtrated through a hot vacuum filtration. The crystals were allowed to thoroughly dry for a week and the mass and melting point were recorded. To extract benzoic acid‚ 3 M of sodium hydroxide was added to the dichloromethane solution‚ and was then acidified with 6 M of hydrochloric acid. Hot filtration was conducted to extract the benzoic acid crystals. They were allowed to dry for a week and the mass and melting point

mixed with glacial acetic acid and stirred in which then bromine/acetic acid solution was added to the mixture little by little. The dibromide becomes the precipitate of this solution during the reaction. Once this precipitate is separated by vacuum filtration the melting point helps identify the product.

Large industries that do not have filtration mechanisms on their smoke stacks are also contributors. Every government which does not pass or passes but does not enforce strict air pollution legislation is also destroying the atmosphere. One may wonder why these three aspects of society show such a lack of concern with the air they breathe. Well‚ the underlying cause which motivates all three groups is money. Legislation and enforcement of laws and installation and maintenance of filtration systems cost money.

In this experiment‚ 5.281g of trans isomers of [Co(en)2Cl2]Cl was synthesized from 12.249g of CoCl2▪6H2O. First‚ CoCl2▪6H2O was reacted with ethlenediamine (NH2CH2CH2NH2) that formed [Co(en)2(H2O)2]Cl. Then the [Co(en)2(H2O)2]Cl was reacted with H2O2 to change the cobalt’s charge to cobalt(III) from cobalt(II). Finally HCl was added into the solution to form [Co(en)2Cl2]Cl. The percent yield was 45.51%.To synthesis trans isomers of [Co(en)2Cl2]Cl‚ distilled water was first mixed with CoCl2▪6H2O‚
