Synthesis of benzilic acid from benzoin utilizing a multi-step reaction. Names: Arian Karim TA Name: Sayantan Das Lab Day & Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5%

Experiment 1: Synthesis of Copper Compounds Introduction This experiment involves the synthesis of compounds originating from pure solid copper. By applying solubility rules and the reactive properties of substances‚ many compounds which would otherwise be costly to extract from nature are able to be synthesized in the laboratory. Laboratory synthesized may sometimes be more economical than natural extraction‚ however it poses its own problems with the amount of substance that is actually yielded

country. Every battle the U.S. fought used some form of intelligence. Covert Action (CA) was used in every battle‚ it was officially documented by an intelligence organization during World War II. This paper will address the question‚ does having the Central Intelligence Agency (CIA) as the responsible body for carrying out covert action create a conflict of interest when it is responsible for both covert/overt action for the purpose of collecting and feeding information for strategic analysis.

Nonconformity‚ Corrective Action and Preventive Action in EMS ISO 14001 The intent of 4.5.3 is that the organization put in place procedures for‚ 1) identifying actual and potential nonconformities to EMS requirements‚ 2) taking appropriate corrective or preventive action‚ and 3) reviewing the effectiveness of corrective or preventive actions taken. The nonconformity requirement of ISO 14001:1996 was a passive requirement in that it was only triggered when a nonconformity came to the attention of

Background of Study 1.1 Problem Statement Some would say that industrial action is a pest‚ eating away at the crux of Pakistan ’s industrial and social development. In many ways‚ this is true. Take for example‚ the doctors calling for strike in 2011 which led to multiple avoidable deaths. But it is also essential at times as it plays a vital role in bringing light to major issues that might be plaguing society‚ and sometimes it is used as a tool to protect one’s rights. In the 2011 incident‚ the

Minimum Wage For years there has been disagreement over whether the minimum wage should be raised or not. Some believe that by raising the minimum wage‚ many Americans would be able to rise above the poverty line and have access to their dream. Others disagree saying that raising the minimum wage would only make it more difficult for businesses to pay workers and people would lose incentive to work hard. The only just choice is to raise the minimum wage so that hard working Americans can exceed

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
