  • Industrial Applications Of Citric Acid

    Organic Acids An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak. In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such as formic and lactic acids are miscible in water, but higher molecular mass organic acids, such as benzoic acid, are insoluble in molecular (neutral) form. A few examples of organic acids include: • Acetic acid (ethanoic acid ) CH3COOH • Citric acid…

  • Ebay Case Study Analysis

    With the matrix structure, it overlaps both the functional design, which is what Omidyar initially started out with and the divisional design. Within the matrix structure method, employees belong to at least two groups at the same time. For example, within the functional areas Omidyar set up initially, someone in finance could have knowledge and work in the operations division of the company and vice versa. The workers would also report to two supervisors – one within the functional group and…

  • Body Synthesis Protocol Analysis

    research has identified the key structural groups of the compound that are essential for its function (Combemale et al., 2013; Kudo et al., 2010; Nakamura et al., 2003). Bioassays examining the structure-function relationship have resulted in a crude comprehension of the potency of HPA-12 and numerous analogues (Fleury et al., 2015; Santos et al., 2015; Ueno et al., 2001; Yasuda et al., 2001). However, from a medicinal chemistry perspective, an important aspect of this appears to have been…

  • Tetraphenylcyclopentadienone Synthesis Essay

    The purpose of this lab was to prepare tetraphenylcyclopentadienone most commonly known as tetracyclone. This involved a 3-step synthesis over the course of 3 weeks. The first step was the preparation of benzoin, which was completed through self-condensation of benzaldehyde with thiamine used as the base catalyst of the reaction. The next step was the preparation of benzil from the oxidation reaction of benzoin with nitric acid. In the oxidation reaction, the alcohol functional group of benzoin…

  • Azo Dye Lab Report

    An activated aromatic ring was needed, and this was where resorcinol came into play; due to its having two hydroxyl groups, it qualified. This solution was placed in an ice water bath; this was necessary as it lessened the amount of side reactions that had a chance of occurring. While the stir bar was stirring to ensure homogenous solution, the salt solution was poured in slowly. This was continued for thirty minutes and then sodium acetate was used to neutralize the solution (pH 5-6) and this…

    (about 87%) of the administered dose is excreted in the urine as MPAG.  In the early post-transplant period (<40 days post-transplant), renal, cardiac and hepatic post-transplant patients had mean MPA AUCs approximately 30% lower and Cmax approximately 40% lower compared to the late post-transplant period (3-6 months post-transplant). Children and adolescents (aged 2-18 years) Pharmacokinetic parameters were evaluated in 49 paediatric renal transplant patients given 600mg/m2…

  • Methylcyclohexane Research Paper

    Introduction The technology of photopolymerization is widely applied in several industrial fields, microlithography [1-3], printing material [4], liquid crystalline [5-9] and nonlinear optical materials. Important advantages offered by this technology are high speed, reduced release of volatile compounds since no solvent are used and low cost of equipment. Also kinetics of photocuring, mechanical properties, inertness to solvents, resistance to abrasion depend on the degree of photocuring and…

  • Caprolactam And Nylon 66

    pollutants by the U.S. Clean Air Act of 1990. It was subsequently removed from the list in 1996. In water, caprolactam hydrolyzes to aminocaproic acid, which is used medicinally. As of 2014 caprolactam had the unusual status of being the only chemical in the International Agency for Research on Cancer's lowest hazard category, Group 4 "probably not carcinogenic to humans". Nylon 6 or polycaprolactam is a polymer developed by Paul Schlack at IG Farben to reproduce the properties of nylon 6, 6…

  • - 6-Diphenyl-2-Cyclohexenone Lab Report

    In the IR spectrum, RM-10-1i, peaks that are present correspond to the functional groups in 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone. These functional groups are sp2 hybridized carbons at 3031 cm-1, sp3 hybridized carbons at 2981 cm-1, a carbonyl at 1735 cm-1, aromatic carbon-carbon stretching at 1660 cm-1, an ester carbon-oxygen stretching at 1144 cm-1, and alkene carbon-hydrogen stretching at 698 cm-1. There was no alcohol present in this spectra, indication that all of the catalyst was…

  • Formation Of Carboxylic Acid Group

    As it was demonstrated in Figure 2, the peaks at 1703 and 1727 cm-1 in the MPS-comprising nanohybrids appeared, while the peak at 1745 cm-1 vanished. Through the formation of MPS-comprising nanohybrids, the observation of the new absorption bands (1707 and 1727 cm-1 ) concomitant of the absorption at 1733 cm-1 may be owing to the formation of ester groups through the reaction between carboxylic acid groups of PAA oligomers and silanol groups of silica moieties 12. Besides, in SiO2/PAA hybrids,…
