Introduction The purpose of this lab is to synthesize Lidocaine from 2‚6-dimethylaniline‚ using diethyl amine‚ 2-chloroacetyl chloride‚ acetic acid‚ and toluene. The Lidocaine was made by adding 2‚6-dimethylaniline to 2-chloroacetyl chloride in acetic acid. Sodium acetate is added in order to make the compound soluble. The product is dried‚ then treated with diethyl amine and toluene. This is refluxed using a water-cooled reflux condenser. The vapor is condensed by the cold water as the compound

EXTRACTION Organic Chemistry Laboratory This experiment was conducted in order to compare single and multiple extraction of caffeine from dried tea leaves and to calculate the percentage yield of caffeine for both extraction procedures. The group was assigned to do the multiple extraction. Before the extraction proper‚ the water bath containing the anhydrous sodium carbonate and distilled water was heated. As the sodium carbonate dissolves‚ tea leaves were added in the mixture and allowed to

Loggerheads also modify habitats as a result of their foraging activities. The fragments of hard-shelled organisms that loggerheads consume are either discarded or ingested and later deposited with feces at a different location. By reducing the particle size of the shells‚ loggerhead turtles contribute to nutrient recycling in benthic ecosystems by increasing the rate of shell disintegration. Additionally‚ a foraging behavior called infaunal mining has a significant effect on substrate characteristics

In the most simple form‚ FM digital synthesis consists of two sine waves. One is called the modulating wave and the other is called the carrier wave. The carrier wave is the only waveform that is audible. The modulating wave does just as it sounds‚ it modulates the amplitude of the carrier wave‚ and acts as a control value. The frequency of the modulating frequency controls the rate of change in the carrier wave; it controls how fast the modulation occurs in the carrier wave. And the amplitude of

The purpose of this essay is to discuss the Islamization of Persia in relation to the Samanid and Buyid Dynasties. The synthesis of Persian culture and Islam was not an immediate result of the Arab expansion into Iran and there is certainly a lack of research on the subject. However‚ in this essay‚ I will attempt to explain the contributions of the Samanid and Buyid dynasties to this synthesis with a focus on the attempts of the Samanid Dynasty at centralization and a unified identity through religion

Table 1. An infrared spectrum for the pure aspirin from the synthesis was taken by using crushed crystals‚ Figure 1. This spectrum was shown with different absorption bands corresponded with the functional groups of aspirin which was observed at frequencies > 1500 cm-1. These infrared frequencies were shown in Table 2. An infrared spectrum of an authentic aspirin was used to distinguish how authentic the infrared spectrum from the synthesis was shown in Figure 2 In this lab‚ aspirin was synthesized

“What really makes us intelligent isn’t our ability to find lots of information quickly. It’s our ability to think deeply about that information.” (Is Google Making Us Stupid?) There are very many risks to technology. This is unfortunate because technology rates are growing rapidly. Some risks to technology include causing distractions‚ and causing addiction. (Source 2) To begin with‚ a risk of technology is causing distractions. “If we’re distracted we understand less‚ remember less‚ and learn
