Carboxylic acid

treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of multi-parameter…

1.3 Aims and Objectives I. To determine the antioxidant activity of leaves of C. nardus II. To determine the antimicrobial activity of leaves of C. nardus 1.4 Scope and Limitation of the study The leaves of C. nardus will be subjected to hydrodistillation in Clevenger-type apparatus to obtain Citronella oil. The antioxidant activity of C. nardus leaves will be determined by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging methods whereas the antimicrobial activity will be…

The objective of the present study is to isolate piperine from the black pepper. Our attempt was to extract the piperine with petroleum ether from black pepper and isolation using the same solvent. It is very difficult to extract and isolate the piperine using a non-polar solvent like petroleum ether due to solubility. During our study, we observe that piperine have a very little solubility in the petroleum ether, at the same time the solubility of the resinous material in petroleum ether is…

even if it has little different melting point from the literature melting point which is 7880°C. Conclusion/Discussion: During the electrophilic aromatic substitution reaction between methyl benzoate and a nitrating solution of sulfuric and nitric acids, the Meta-Methyl nitrobenzoate product was obtained based on the product melting point range. Percent yield of the crude 56.42% and the percent yield of the recrystallized product was 52.59%. This would indicate that during the recrystallization…

EXTRACTION OF A KNOWN MIXTURE Separation of mixture of Acetyl salicylic acid (aspirin) and naphthalene Experiment # 6 Introduction A technique called extraction will be demonstrated in this experiment. Extraction relies on the solubility of substances into solvents and the insolubility of the solvents into each other. In this experiment, three organic compounds (aspirin and naphthalene) will be separated from each other. The two compounds are all soluble in ethyl ether (an organic solvent). By…

slurry. The slurry was then poured into the column and the solvent just about the silica was drained off into a conical flask. To minimize losses, the silica slurry beaker was rinsed with more chloroform and added to the column. Next, a thin layer of acid washed sand (3mm – 4mm) was added to the column. Next, two ‘curcumin soft gels’ was puncture using a scissor and spatula. The soft gels were squeezed and added to a 50 ml beaker with 30 ml of chloroform. The mixture was mixed well and the…

Title: Methylcobaloxime: A Model for Vitamin B12 Aim: To create methyl(pyridine)cobaloxime(III) as a model for methylCobalamin, the methylated form of vitamin B12, Introduction: Using Co(I)Cl2 as a starting material, it is possible to produce a cyano(pyridine)cobaloxime like compound, Chloro(pyridine)cobaloxime whose chemistry can be investigated via means of methylation, as such using the Chloro(pyridine)cobaloxime as a model for replicating chemistry already known of…

Acetic Acid or better known as vinegar is a compound formed by the chemical reaction of carbon, hydrogen and oxygen. The composition of vinegar is acetic acid (C2H4O2) and water. Also, the formula for this compound is CH3COOH. These elements are nonmetals,so the type of bond that this substance made is covalent. Vinegar has many kind of properties and utilization in several ways. For example, it can be use for food preparation, cleaning and health. When added in water it makes an acid…

Enough hydrogen peroxide should be administered in order to degradate the possible intermediates formed such as carboxylic acids and quinones. In order to determinate this, COD was measured. The presence of chlorine ions retarded the degradation of the intermediates while the sulfate ions had the same affectation as the reaction with pure phenol. In the case of 2-chlorophenol…
