century. The final product will then be evaluated in comparison to salicylic acid made from benzene. Discussion – In this synthesis‚ methyl salicylate is the starting material or precursor and salicylic acid is the target product. It is the major constituent of wintergreen oil. The difference in structures between methyl salicylate and salicylic acid is a single functional group. In methyl salicylate the benzene ring is substituted by two functional groups‚ a hydroxyl group (-OH) and an ester group

routes is reviewed. Production of KA oil from phenol is also covered‚ as is the Asahi process for cyclohexanol production from benzene via cyclohexene. Appropriately adjusted nitric acid oxidation is appended to each of these processes. Solutia‚ working with the Boreskov Institute of Catalysis (BIC) in Russia‚ has developed a one step process to manufacture phenol from benzene‚ using nitrous oxide for the oxidation step. Thus‚ by coupling phenol production and adipic acid production‚ Solutia has

and tri- substitution. Meta directors don’t have that unshared electron pair that is used to push an atom closer to the benzene ring. In our reaction above the substitution would be more di-substitution favored. The positive charges are further away from each other in the benzene ring. Most if not all meta directors have a group with-full positive charges next to the benzene ring. If perhaps you were to be given different results maybe their would be an increase in temperature that would result

determine the structure of the major component of star anise oil. It is already known that this component has a molecular formula C10H12O. This molecular formula equates to an IHD of 5. It is evident‚ by calculating the IHD‚ that this compound contains a benzene ring. By heating anisene with hydroiodic acid the following reaction occurs: [rxn 1] The resultant of a phenol indicates that anisene is‚ in fact‚ an aryl methyl ether with the formula C9H9OCH3. Since all these facts have been established about the

What is the mole fraction of hexane? Solution: 1) You need to determine the moles of pentane‚ hexane and benzene: to do this‚ you need the molecular weights. Here are the formulas: pentane: C5H12

The weak carbon-carbon double bond peak located at 1621 cm-1 indicates the presence of a trans alkene. This is also supported by the peak located at 964.93 cm-1‚ the trans isomer peak. The two peaks at 1621.31 and 1516.29 cm-1 along with the overtones located around 1900 cm-1 indicates the presence of a benzene ring. Based on this data‚ it can be concluded
