determine the specific isomer of the bromovanillin produced. In this experiment, vanillin is brominated to produce a mixture of isomers or one single isomer of bromovanillin. The possible product(s) formed are 2-bromovanillin, 5-bromovanillin, and 6-bromovanillin, as seen in Figure 1.1 By utilizing the bromination process of vanillin, one bromovanillin isomer can be formed as a result. As the starting material, vanillin can work with various electrophilic aromatic substitution reactions, due to the
The purpose of this experiment is to perform a two step reductive amination using o-vanillin with p-toluidine to synthesize an imine derivative. In this experiment, 0.386 g of o-vanillin and 0.276 g of p-toluidine were mixed into an Erlenmeyer flask. The o-vanillin turned from a green powder to orange layer as it mixed with p-toludine, which was originally a white solid. Ethanol was added as a solvent for this reaction. Sodium borohydride was added in slow portion as the reducing agent, dissolving

Vanillin Vanilla is a complex mixture of flavour that is extracted from vanilla orchids. The most important ingredient in vanilla is vanillin. The vanilla flavour is widely used as a flavouring agent in the food, fragrance and pharmaceutical industries. However, due to the high cost and scarcity of natural vanillin, the flavour and fragrance industries have resorted to synthetically produced vanillin. The primary opportunity is in providing a competitively priced product that is naturally synthesized
was close to Acenapthene’s literature melting range. With these two points, my partner and I believed our unknown B8 to be Acenapthene. According to our recrystallized vanillin, we know that our vanillin was pure because of its melting range. Our recrystallized vanillin was the same as the literature melting range of the pure vanillin. Lab #1 Post
are a little chunky, through the mixing and blending process they become a smooth paste. The product is then unloaded from one Blend Tank to another where the Nutella is produced. The cocoa powder is then mixed with the hazelnuts along with sugar, vanillin and skim milk in a large tank until it becomes a paste-like spread. Modified palm oil is then added to help retain the solid phase of the Nutella at room temperature, which substitutes for the butter found in the cocoa bean. In addition, whey powder
The poem “Pepsi” by Nickole Brown, explains how Brown’s comparing different things to soda. Early on in the poem she makes a comparison of different types of fish like a catfish, bass, and trout. She uses numerous metaphors to tie in the different comparisons. In this poem we learn about her Fanny was lost and went into a coma. When she got out of the a coma she became the Fanny that everyone knows who is sassy towards her loved ones. We also see that she has a fresh pepsi this time after she got
P. zeylanica yield the following results. The Rf values and colour of the spots were recorded (Table 25). Photodocumentation under 254 nm gives 6 spots (Fig 16a), 14 spots under 366 nm (Fig 16b), and 9 spots under 620 nm post-derivatization with vanillin sulphuric acid spray reagent (Fig 16c). Densitometric scan at 254 nm revealed 7 peaks
2014). To meet the increasing demand of vanilla, a biotechnology company called Evolva made use of synthetic biology (synbio) to produce vanilla using yeast. By altering the DNA of yeast, the metabolic process of yeast is modified to synthesise vanillin, a primary component of vanilla, through fermentation (Benson, 2014). As synbio vanilla is the first major application of synthetic biology in food, it has sparked off controversy among biotechnology companies, civil society organisations and consumers
This topic is about how shoes were made, where they first were made, and who they were made by. How did these shoes become a thing, what kinds of styles are there. These things affect us in everyday life, because we can 't go walking around barefoot on hot or rocky pavement. The earliest shoes are sandals. Most Native Americans went barefoot. The design of shoes has varied enormously through time and from culture to culture, with appearance originally being tied to function. "Shoes are also used
Who is Monsanto? “Monsanto is a sustainable agriculture company,” according to the company’s own website (“Who We Are”) According to Ken Cook, head of the Environmental Working Group, “a company like Monsanto is a world of its own. The pursuit of profit at any price anesthetizes people devoted to a single purpose: making money” (Robin 15-16). Cook is indicating that this company does not form its business ideas around the notion of “sustainable agriculture”, but rather making copious amounts of money
MeOH: CHCl3 (20:80) bioactive fraction. Thin-layer chromatography (TLC) analysis of MeOH: CHCl3 (20:80) fraction was carried out using a solvent system containing MeOH (15%) and Ethyl Acetate (85%). The TLC plates were visualized by spraying with vanillin- HCl reagent resulting in a UV sensitive band, which on heating, developed green color. The UV sensitive bands were purified using repetitive preparative TLC followed by crystallization. The identity of Ecdysterone was established by the following
It is a leading manufacturer of genetically modified seeds, founded in 1901. Originally, Monsanto manufactured food seasonings and additives such as vanillin. They then expanded into industrial chemicals such sulfuric acid. By 1940, they began to produce plastics such as polystyrene and synthetic fibers. In 1963, Monsanto was one of the first companies to genetically modify a plant cell and began running
3.1 Phenolics in buckwheat honey Figure 1 illustrates the wide variety of HPLC profiles of six buckwheat honey samples. As can be seen, these samples could be divided into two main types. The first type exhibited very similar chromatograms, including samples 1, 2, 3 and 4. The retention time of most compounds is 20 to 70 min. Conversely, the second type include sample 5 and 6. Their chromatograms appeared simpler and showed only a few lower level peaks. The figure showed the highest peak is
Introduction Nowadays, with the modern technology development, there are more and more different chemistry uses in food industry, like food storage, transportation and many ways which will need food additives to keep food fresh and nutritious. The food additive’s main difference lies in whether it is naturally formed or artifically synthesized. Except from this, China divides food additives into 24 different food additives including flavoring agents, coloring agents, bleaching agent, texturizing
Mary Shelley’s Frankenstein is closely related to the current issue of genetic engineering. Shelley’s main character, Victor Frankenstein, is a scientific engineer who brings different parts of people’s bodies together to make a new creation. This new creation at first seemed good to Victor however, he was eventually overcome by it. Genetic engineering is not only gene manipulation; it is a desire to take parts of an organism and create a new living thing. Shelley was 17 years old when she wrote
