3-(4-acetylphenyl)-6-bromo-2-(4-chlorophenyl)quinazolin-4(3H)-one (2) Compound 1 ( 0.01 mol) fused with p-aminoacetophenone ( 0.01 mol) at 160 oC in an oil bath for 2 h. Crystallized from ethanol to give redish brown crystals of 2, m.p. 210oC in 80% yield. Analysis for C22H14BrClN2O2, Calcd.: % C, 58.24; H, 3.11; N, 6.17, Found: % C, 58.31; H, 3.17; N, 6.20, IR spectrum (KBr, cm-1) showed characteristic absorption bands at 3380 (C-H aromatic), 1710 (C=O of acetyl), at 1690 (C=O of…

Good essential oil recipes or essential oil blends can heal the physical body and bring wholeness and health to body, mind and spirit. What constitutes an "essential oil recipe?" In aromatherapy, when we create a recipe we are actually blending various oils together for a particular purpose. All essential oils have the power to affect us emotionally and spiritually but only those that are right for the individual at this particular juncture in their healing process will possess the subtle…

The lab instructions provided five components of cinnamon oil, of which one is the major component of clove oil. Of these five chemicals, only one, eugenol, has a phenol functional group. Because the IR spectrum of the distilled clove essential oil had a weak, broad peak around 3200 to 3500 cm-1, which corresponds to the hydroxyl/phenol functional group, there is evidence that eugenol is the major component of clove oil. Furthermore, since the IR spectra for the other four given chemicals would…

1.3.3 Lipid oxidation While not a direct outcome of proteinaceous compounds, aldehydes such as hexanal and (E)-2-nonenal have been attributed to the oxidation of lipid components present in the raw material (Aaslyng et al., 1998b). They are often present in much higher concentrations in enzyme hydrolysates and have been correlated to beany off-odours described in numerous literature. Solina et al. (2005) compared the volatile components of soy protein isolate (SPI) and acid-hydrolysed soy…

Chapter Three - Conclusions 3.1 Conclusions This research aimed to verify the synthesis protocol for HPA-12 and analogues from aldehydes of Greatrex et al. (2014). Limited success in synthesising required quantities had a negative impact on the outcomes of this research, and no reasons were identified for the low yields that were obtained. Additional time, or resolution of issues resulting in low yields, would have allowed additional research and confirmation of the synthesis protocol. Long…

D.Macro-environmental analysis by Chanel Chanel No.5 has been the product with the greatest sales and lengthy history in the Chanel perfume business. This company keeps improving and advancing the corporate philosophy due to time changes to meet consumers’ ideal expectation. This part emphasizes on demonstrating the macro-environmental analysis by Chanel No.5 Political Factor A political factor or legal factor refers to governmental policies which could include the preference and priorities of…

conducted in order to learn about the Hantzsch 1,4-Dihydropyridine synthesis mechanism. Furthermore, this lab will give students a better understanding of the terms pharmacophore and a privileged structure. In order for this reaction to occur an aldehyde, ammonia, and two equivalents of a B-ketoester go through a one-pot cyclocondensation reaction. After 1,4-dihydropyridine is formed, it is then oxidized to form its pyridine derivative. Alcohol or Acetic acid is then used as a refluxing solvent…

INTRODUCTION The objective of this experiment was to group a variety of samples of matter into subcategories of different macromolecules, which were determined by the use of various tests, as well as designated negative and positive control samples. Chemical samples may be experimentally identified as specific macromolecules through treatment with Benedict’s solution, the iodine test, or the Biuret test; each, when positive, identifying reducing sugars, starch or glycogen, and protein,…

unknown B, it was possible to be an alcohol. Alcohol released a lot of the soot during combustion. It does not react with bromine due to absent of carbon-carbon double bond. Primary and secondary alcohol can react with potassium permanganate to form aldehyde or ketone but not tertiary as it does not have hydrogen that attached to carbon. When the primary or secondary alcohol reacted, the solution is decolourised and brown precipitate (manganese dioxide) was…

Smoking is a contract with cancer and many other harmful diseases, but with the new rise in e-sigs (Vaping), is it harmful. We all know that smoking is very bad and every one shuns it, but why do people never talk about the effects on vaping, is it bad for you or does it not do anything. Vaping is a broad topic, some have nicotine, some nothing but vapor, and some have vitamins in it. Some factors of vaping are harm full, but there is some ways it is healthy.…
