Synthesis of Banana Flavor CHEMISTRY 200L EXPT 02 PAGE 01 - 11 Gerome B. Vallejos*, Ellis Mika C. Trino, Jahn Camille B. Valdez, Ariza Yamashita Department of Biological Sciences, College of Science Group 11 Corresponding author: gerome_911@yahoo.com Abstract The purpose of this experiment was to synthesize isopentyl acetate via Fischer esterification reaction between acetic anhydride and isoamyl alcohol, using concentrated sulfuric acid as a catalyst. This reaction is characterized by the combining of an alcohol and an acid (with an acid catalyst) to yield and ester plus water. In order to accomplish this reaction, the reactants were refluxed for 30 minutes at 80 degrees Celsius ,to yield a mixture, the mixture was then mixed with†¦show more content†¦Isopentyl acetate is known as banana oil because of its characteristic odor. This ester has also been shown to be one of the active substances in the alarm pheromone of the honeybee. The pheromone causes other bees to become aggressive and attack the intruder. In the experiment, the Fischer esterification will make the acid and alcohol reactants to be in equilibrium with the assigned ester, isopentyl acetate, to prepare an artificial Banana flavoring. Then isoamyl alcohol will be r efluxed with acetic anhydride and with concentrated Sulfuric acid as the catalyst. The product is isolated using a combination of technique such as acid-base extraction, drying, and in special case of distillation. Results and Discussion Isopentyl acetate Acetic anhydride Isoamyl alcohol Scheme 1.1 Fischer Esterification of Banana Flavor The scheme above summarize the whole experiment, its shows the reaction between isoamyl alcohol and acetic anhydride together with the catalyst which is sulfuric acid. Before the experiment was performed, the Limiting reagent was first computed between isoamyl alcohol and acetic anhydride, to obtain the theoretical yield. The computation would not be possible without the different molecular weight, volumes and densities given in Table 1.0: Table 1.0 Molecular Weight, Volumes and Densities of the Reagents and Products.

An Organizational Behavior Management Course - 1722 Words

Prior to enrolling in an Organizational Behavior Management course I had no idea of all the necessary skills one must acquire in order to be a successful professional in the workplace. After being introduced to the multiple aspects that play an important role in the making of a great manager I learned that there are some aspects that are more crucial than others. Perhaps, some of the most fundamentally important ideas in management are the leadership, personality, motivation, decision-making and communication skills of the individual. In my experience, I view a good and effective manager first and foremost as a leader. A well-rounded manager has a personable personality and can engage and motivate a multitude of different personalities.†¦show more content†¦An important aspect that I would need to consider is how crucial organizational behavior is to the work place. Diversity is definitely something that will always exit in the workplace but from this course I have learned t hat diversity in the work place brings more advantage to the company because individuals with different skills come together in order to accomplish mutual tasks. However, it can definitely be affected negatively by factors such as prejudice, discrimination, stereotyping and racism. I would need to be aware of the fact that these differences will exits, however, I will have to develop ways to deal with those type of issues by coming up with basic workplace principles based on mutual respect and adherence to laws that prohibit discrimination and acknowledging that it should not be an issue when it comes to getting the job done. Another aspect that will be helpful in my future job is being aware of all the benefits I can bring due to globalization. By learning about the globalizing economy I can learn to expand and compare how other countries work and what I can do to improve myself and the rest of the company that I will be working for.

Ontario Teachers Strike Essay Example For Students

Ontario Teachers Strike Essay Education is probably the most important resource in our society. The education System determines our future, by educating the youngest segment of our population. For this reason, it should be of great concern when there is a problem or an issue like a Teachers strike. The Ontario teachers strike that began on Monday October 27 involves 126,000 teachers and affects 2.1 Million students in the province. This strike is North Americas largest, right ahead of the 1975 New York City strike when 60,000 teachers walked off the job . The main issue of debate is over Bill 160, which is all about who holds The Power to set education policy in the province of Ontario. Bill 160 centralizes control of the education system, putting it in the hands of the provincial government. It eliminates the authority of school boards and teachers unions to set classroom and teaching conditions locally through collective bargaining. The bill allows the government to regulate class sizes, education property tax rates, teachers preparation time, the amount of time teachers and students spend in school and the use of non-certified instructors. The issue is whether teachers should have a role in educational reform. of great concern when there is a problem or an issue like a Teachers strike.

Bill 160 centralizes control of the education system, putting it in the hands of the provincial government. It eliminates the authority of school boards and teachers unions to set classroom and teaching conditions locally through collective bargaining. The bill allows the government to regulate class sizes, education property tax rates, teachers preparation time, the amount of time teachers and students spend in school and the use of non-certified instructors. The issue is whether teachers should have a role in educational reform. The strike is illegal, because most of the te! achers have existing contracts. Ontario premier Mike Harris said that reforms are needed to stop a decline in student performance. Although the same government announced that the bill will allow the education ministry to cut 7,000 teaching jobs and up to $700 million from the $14-billion education budget. The strike is not a typical one, because its not really a labor issue.Its not about teachers fighting a school board over a collective bargaining agreement. Its a strike protesting against the Harris government and Bill 160. While the teachers want to protest Bill 160, they also have an obligation to teach their Students.Many teachers are caught in this dilemma; do you go to the classroom, or do you go to the wall to defend education? Are teachers responsible first and foremost for their students or should they be loyal to the union?Many teachers in Ontario feel that they should be there for their students, although theyre Scared To cross the picket line.Eileen Lennon, president of the Ontario Teachers Federation, has said that teachers who cross picket lines wont be sanctioned.However, they might take heat from individual co-workers when they get back on the job.The Teachers feel that they have to show solidarity with the union, or they will be alienate! d. Parents should be on the alert that their schools may be closed in the very near future, Lennon said. When we do it, it will be province wide. Union members met with education minister Dave Johnson over changes to Bill 160, although nothing was resolved.Johnson said he was discouraged following a one-hour meeting with representatives of the five major teachers unions. He said he would not make changes the unions demanded. I was presented with a list of issues to pull out of Bill 160, Johnson said. Ive been presented with an ultimatum to take these sections out of Bill 160 and further discussions, according to the Ontario Teachers Federation, are not able to take place until those sections are taken out of the bill. Union leaders said they asked Johnson to remove some provisions that would allow the province to use non-certified teachers in classrooms and to regulate class size, teacher preparation time and the amount of time teachers spend in the classroom.Johnson says the changes are necessary to improve the quality of education. The government and the unions have each spent over 1 million dollars in advertising, trying to win Motivating Employees Essayover the support of the people of Ontario.The most recent polls show that the unions have a slight edge over the government as they prepared for the illegal strike.Though the longer the strike lasts, the opinion will shift to the gove.. rnment. The question is: How long will people put up with the inconvenience in light of the over-arching motives? Right now, tone and character become extremely important. Opinion on the issue is constantly changing, with a shift of two or three percentage points a day over the last week, most of it going to the government.
