Through thorough investigation, the answer to this question and many more can be answered. There are two methods of obtaining cyclohexane. These two methods are fractional distillation of naphtha and hydrogenation of benzene. Research suggest that the hydrogenation of benzene is the most economical way to create our chemical of choice. According to ICIS, cyclohexane is used in the production of adipic acid used to
The extent of reaction was found to decrease with an increase in temperature from 50 to 60ºC. Because at high temperature, the active site of the enzyme got denatured and no more accessible for distinguish substrate 25. However, with an increase in the enzyme amount above 2 %, decreases the percentage conversion. This can be attributed to disruption of enzyme tertiary structure and denaturation at high temperature
2005), biocompatible (Zinn et al. 2001; Hazer and Steinbuchel 2007) and are produced by bacterial fermentation using renewable resources. Hence PHA has potential as alternative material for conventional petrochemical-based plastics. Biobased materials such as polynucleotides, polyamides, polysaccharides, polyoxoesters,
Then percent yield was calculated to be 67.57%. The isolation of less product resulted from using less amount of acetanilide than 0.07g at the beginning of the experiment. In addition, the melting point of the product was measured to be 164.8-168.50c, which is in the range of the normal melting point of 4-bromoacentailide, 165-1690c. This confirmed the formation of 4-bromoacetanilide from the bromination of acetanilide. From the bromination of 0.05g aniline, 0.156g of the product was collected.
Conclusion It was clearly observed that the decrease in the concentration of hydrogen peroxide lead to increase in the reaction time and also decrease in the rate of the reaction. Also the decrease on the concentration decreases the rate of the reaction. The two graphs were straight line graphs with positive slopes. So effective collision for a chemical reaction depends directly on the concentration of the reagent, that is, the crowdedness of the reacting molecules which increases reaction time and vice versa.

The anthraquinone dye experiment has the purpose to identify the anthraquinone dyes from unknown mixture by using thin layer chromatography (TLC) of the unknown fraction. An anthraquinone is an aromatic organic compound obtained by the oxidation of anthracene. To separate the compounds in the mixture, column chromatography and thin layer chromatography uses portioning of a sample between a stationary solid phase and a liquid mobile phase. As the stationary phase, they use either silica gel or alumina, and organic solvents as the mobile phase. In order to accomplish the experiment, an unknown which is a solution of at least two anthraquinone dyes will be used.
The results from the lab supported the initial hypothesis that catalase will have the highest reaction rate when exposed to a temperature around 37℃ as a reaction rate of 5 was obtained when catalase was at a temperature of 30℃. This lab explains the trend between temperature and reaction rate, as an enzyme’s activity will increase as temperature increases until it reaches the optimal temperature, in which case the activity will start to decrease. Theories like protein structures and intermolecular forces were justified by the results of this lab as well. Moreover, the activity levels of enzymes are greatly impacted by temperature and it should be further investigated through scientific applications with
This proves that my hypothesis was correct. Furthermore, my data compared to other resources are fairly similar. The rate of reaction approximately doubles every time the temperature increases by the 10°C (Ingram, Paul). Whereas my rate of reactions double every 20°C instead of 10°C. This tells me that I was not accurate enough with my timing and measuring.
