reactions that produce folic acid which acts as a coenzyme in the synthesis of purine‚ pyrimidine and other amino acids. In part C‚ Fluorene was dissolved in three solvents. Fluorene(C13H10) is a polycyclic aromatic hydrocarbon. It forms white crystals that exhibit a characteristic‚ aromatic odor similar to that of naphthalene. It is combustible. It has a violet fluorescence‚ hence its name. For commercial purposes it is obtained from coal tar. Results: In part A‚ .30g of impure Sulfanilamide was

other compounds gave a negative result since they are all hydrocarbons. INTRODUCTION Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar

The present invention relates to polyvinyl chloride plastisol compositions‚ for example sealant compositions. In the manufacture of automobiles‚ the automobile body is initially primed with a coating composition to prevent corrosion of the metal. This can be done in a number of ways although generally it is performed by cationic electrodeposition using the auto body as the cathode. Once the automobile body has been primed in this manner‚ subsequent steps in the assembly are carried out. These

Preparation and purification of acetylsalicylic acid Results and Data treatment (A) Preparation of aspirin i) Details about the reactants Reaction of the acetylation of salicylic acid is following From the balanced reaction above‚ it can be seen that the stoichiometry between salicylic acid and acetic anhydride is 1: 1. In this experiment‚ 21.7mmol of salicylic acid was used to react 6.0mL of acetic anhydride and salicylic acid was limiting reagent. The expected amount of salicylic

The two doublet of triplet peak sections at 6.7 ppm and 7.4 ppm represent the aromatic Hydrogens‚ which covers four of the nine Hydrogens proposed by the hypothesized formula. The integrated values for the aromatic peaks includes 1‚ 2‚1.9‚ and 1.4‚ which indicates that the integrated values will be off for some of the peaks. The peak at 2.0 ppm represents standard methyl Hydrogens‚ and the singlet split means that the methyl Hydrogens are isolated from other Hydrogen environments in Acetaminophen. Based

CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value

and the rate-determining step is bimolecular‚ two species are involved in one step of the mechanism. If the alcohol in equation (1.0) were to undergo an E2 mechanism then the beta hydrogen would be eliminated (the nucleophile would attack the electrophilic carbocation)‚ C-C pi bond would be formed‚ and the leaving group would leave all in the rate determining step. Additionally‚ equation (1.0) only shows one product‚ which is not true for all alcohols. Certain alcohols can produce more than one
