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 (-COOCH3). In salicylic acid the ester group is replaced by a carboxylic acid group (-COOH). The process that causes the ester group to be replaced by a carboxylic acid group is an example of ester hydrolysis under strongly basic conditions. The following is a mechanism

The Grignard Synthesis of Triphenylmethanol Organic Chemistry Lab II March 19‚ 2012 Abstract The purpose of this experiment was to synthesize the Grignard reagent‚ phenyl magnesium bromide‚ and then use the manufactured Grignard reagent to synthesize the alcohol‚ triphenylmethanol‚ by reacting with benzophenone and protonation by H3O+. The triphenylmethanol was purified by recrystallization. The melting point‚ Infrared Spectroscopy‚ 13C NMR‚ and 1H NMR were used to characterize and confirm

of the recession in 1990‚ the luxury market took a hit and Mercedes-Benz struggled with cost efficiency‚ product development‚ material purchasing‚ and problem in adapting changes. A modular construction process was used to produce the AAV. Functional groups with representatives from different areas like marketing‚ development‚ engineering‚ purchasing‚ production‚ and controlling were used to design the vehicle and production system. From the concept development to production commencement‚ it only

describe the type and position of functional groups in the compound. The steps to naming an organic compound are: 1. Identification of the parent hydrocarbon chain. This chain must obey the following rules‚ in order of precedence: 1. It should have the maximum number of substituents of the suffix functional group. By suffix‚ it is meant that the parent functional group should have a suffix‚ unlike halogen substituents. If more than one functional group is present‚ the one with highest

Synthesis of Phenols You can prepare phenols in large quantities by the pyrolysis of the sodium salt of benzene sulfonic acid‚ by the Dow process‚ and by the air oxidation of cumene. Each of these processes is described below. You can also prepare small amounts of phenol by the peroxide oxidation of phenylboronic acid and the hydrolysis of diazonium salts. Pyrolysis of sodium benzene sulfonate In this process‚ benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt

Figure 1 depicts an IR spectrum for the product synthesized. An IR spectrum demonstrates peaks for specific functional groups‚ which are present in the final purified product. Table 2 is a representation of important peaks in Figure 1 and demonstrates there was a peak present in the IR spectrums wavelength at 1738 cm^(-1). This peak ultimately depicts a carbonyl group based off of an carbonyl group’s wavelength ranging from 1750-1705 cm^(-1). According to Webbook.nist‚ the literature IR
