Mm1 Synthesis Lab Report
3. Results and discussion 3.1. Exploratory experiments with MM1. In the present work, 17 ILs with different cations and anions were synthesized to evaluate the effect of different molecular structures on the extraction of N-compounds. To our knowledge, the synthesis of some ILs from Table 4, for example, tetra alkyl ammonium with different carboxylic anions has not been published yet. As it was stated in the objectives, the selection of the Feed/IL ratio aimed at the least amount of IL required for reducing the N-content just enough to facilitate the HDS process. In this case, by using IL 1 and the MM1, MM2 and MM3 mixtures (Figure 2), it could be seen that a ratio of 20/1 was sufficient for attaining a good extraction level. It seems that the …show more content…
It was difficult to find an IL that worked well extracting all the N-compounds. In general, it was observed that the nitrogen removal of the synthesized ILs was higher for indole and carbazole than for quinoline (Figure 3). The reason behind this behavior is that quinoline is a Lewis acid, while indole and carbazole are Brӧnsted acids. The imidazolium ILs containing halogen anions showed a good removal efficacy, while the change of anion from chloride IL 1 to dicyanamide IL 2 decreased the extraction efficiency of N-compounds. The presence of double imidazolium rings in the structure of the ILs (ILs 4-5) or aromatic derivatives (IL 7) led to the reduction of the removal properties. Butyrate, hexanoate and octanoate of triethylmethylammonium showed excellent indole extraction capabilities , while the change of the triethylmethylammonium cation (ILs 9-12) for the choline cation (ILs 15-17) resulted in the decrease of the extraction efficiency. It is also noteworthy that the increase in the carbon number of the carboxylic chain in ILs from 9 to 12 and from 15to 17 increased the carbazole removal capabilities of the

Group 1 Lab Report
1195 Words | 5 PagesGroup 1: All the elements that were tested from group 1 had a pH level of 12. This meant that all the tested elements produce an alkaline solution. Group one elements readily lose their valence electron as they wish to form a full valence shell this gives them all a low electron affinity. The group one elements have different electronegativity going down the group. Electronegativity of the elements decreases with the increasing the atomic radii.

Methylcyclohexene Lab Report
606 Words | 3 PagesA control was used to compare the reactant and the product, showing a clear appearance that would indicate an alkene being present. Bromine was added to the reactant 4-methylcyclohexanol, and a reddish-brown color appeared, indicating that no reaction took place. Bromine was then added to the product 4-methylcyclohexene, and the clear appearance of the product remained, concluding that an alkene is indeed present. Discussion Given the results obtained post-experiment, the percent yield was calculated to be about 35.5%, which may suggest that either product was lost at some point during the experiment, or side product was formed.
Eucalyptol Synthesis Lab Report
135 Words | 1 PagesABSORPTION, DISTRIBUTION AND METABOLISM: Eucalyptol is quickly absorbed from the gastrointestinal tract. It is lipid soluble and absorption is enhanced in the presence of milk. Inhalation of the liquid is directly toxic to the lungs; however there is no data suggesting systemic absorption via lungs 8. Eucalyptol undergoes oxidation in vivo with the formation of hydroxycineole which is Excreted as glucuronide 9.

Synthesis 3-4 Analysis
116 Words | 1 PagesStandard N is connected to synthesis 3-4, because we wrote a story about a song that had to include all of the standards points. The assignment that I wrote was to write a story about a song of my choice so I had to create a setting, situation, problem, one or more points of view, and introducing characters. This standard helped me understand how to write correctly and to show my strong and weak points. Therefore, It will help me grow in my literary knowledge and my writing skills for a job interview. I think that I did fairly well on this standard, but I need to work on my punctuation skills, and my tense usage.
O-Vanillin Lab Report
840 Words | 4 PagesThe 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 the precipitate into a yellowish lime solution.
Mass Spectrometry Report
1442 Words | 6 PagesIonization refers to the production of gas phase ions suitable for resolution in the mass analyser or mass filter. There are a many on sources available, each has advantages and disadvantages for particular applications. For example, Electron Ionization (EI) gives a high degree of fragmentation, yielding highly detailed mass spectra which when skilfully analyzed can provide important information about structural elucidation/characterization and facilitate identification of unknown compounds by comparison to mass spectral libraries. However, EI is not suitable for coupling to High-performance liquid chromatography, since at atmospheric pressure, the filaments used to generate electrons burn out rapidly. Thus EI is coupled predominantly with Gas Chromatography, where the entire system is under high

Prin Cyclization Reaction
3108 Words | 13 PagesIn detail, the Prins cyclization of homoallylic amines takes place in a fashion similar to that of homoallylic alcohols, whereby the non bonding electrons on the nitrogen initiate the sequence of reaction steps by attacking the electrophilic site of the aldehyde activated by an acid catalyst. The key intermediate of the aza-Prins cyclization is an iminium ion, in analogy to the oxonium ion. Compared to classical Prins cyclization, examples of aza-Prins cyclization using iminium ions leading to nitrogen-containing heterocycles have been less developed in the literature due to less electrophilic nature of iminium ions compared to oxo-carbenium ions. Whereas, aza-Prins cyclization of acyclic/cyclic N-acyliminium ion intermediates to achieve piperidine ring containing mono and bicyclic compounds is well explored due to more electrophilic nature of N-acyliminium
