the nitrogen atom. The nitronium ion‚ acting as the electrophile in the nitration reaction‚ will attack the benzene ring and produces the nitrobenzene ring. Resonance-stabilized arenium ion is created when the nucleophilic carbon pi bond on the acetanilide reacts with the nitronium ion. The aromaticity of the compound is lost in this important step. Water‚ acting as the Lewis base‚ removes a proton from the carbon bonded to the nitro group‚ an aromatic benzyl structure is created again: nitroacetanilide;

Literature Survey 2. Literature Survey Literature survey indicated 135 possible routes for the synthesis of 2-Aminobiphenyl. It must be noted that all routes available were lab-scale and no patents for the desired compound were available. Also‚ majority of these synthesis routes gave extremely low yields of our desired product and produced a number of other by-products in higher yields. Therefore‚ only the pathways giving significant yields of the desired product have been listed below. i. Suzuki

with metallic oxides. These composites which are conducting polymers have been widely used because of their lower density as well their good environmental stability as in the case of polyaniline (PAN). In the present work ‚ in situ polymerization of aniline was carried out in the presence of Fe3O4 nano particles to synthesize polyaniline/Poly(p-hydroxyaniline)/ Fe3O4 (PAN/PHAN/ Fe3O4) composites. The composites‚thus synthesized have been characterized by Fourier transfer infrared(FTIR) spectrophotometer

asses the pharmaceutical preparation of Panacetin‚ by using it ’s solubility along with other organic molecules. We know that Panacetin is made up of sucrose‚ aspirin and some other unknown substance. We know the substance has to be Phenacetin or Acetanilide. To help solidify our reasoning‚ we need a % recovery of 8-12% sucrose‚ 35-45% aspirin and 45-55% unknown. Sucrose for example is insoluble in dichloromethane‚ while aspirin is soluble in CH2Cl2‚ but not in H2O. The organic compound sodium hydroxide

nitrogen atom instead of the carbon of the chain‚ are designated by a capital N. Aromatic amines belong to specific families‚ which act as parent molecules. For example‚ an amino group (—NH2) attached to benzene produces the parent compound aniline. Basicity of amines Amines are basic because they possess a pair of unshared electrons‚ which they can share with other atoms. These unshared electrons create an electron density around the nitrogen atom. The greater the electron density

use of catalysts while minimizing potential chemical accidents. Results and Discussion The Oxone epoxidation reaction is a two-step mechanism that includes forming the dioxirane first. The second step is using the dioxirane to attack the trans-anisole. The mCPBA reaction is a one step that forms the trans-anethole oxide. The result of the Oxone epoxidation reaction yielded 0.96 g of product which was 65% yield. The result of the mCPBA epoxidation reaction yielded 1.03 g or product which was 70%

SOLVENT EXTRACTION Solvent extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up
