Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

Each grain of sugar is made of a small crystal that is made of an arrangement of molecules called sucrose. In a sugar crystal‚ the sucrose molecules are arranged in a pattern that extends in all three dimensions‚ and all of these molecules are attracted to each other by a type of interaction that binds molecules together called intermolecule forces. When you add granulated sugar to water‚ some of the sucrose molecules start separating from one another because they are attracted to the water molecules

Introduction Chemists often find a method to determine the level of “greenness” of a chemical reaction‚ or its “atom economy”. A higher atom economy is preferable because a greater amount of the reactants will be present in the product as opposed to the byproduct.1 A Suzuki reaction is classified as an organic‚ coupling reaction that includes boronic acid and a halide that are catalyzed by a palladium complex under basic conditions. Other palladium- catalyzed coupling mechanisms include the Heck

Name Period Date The Synthesis of Aspirin Background Pharmaceutical research labs perform chemical reactions between organic molecules that contain mostly carbon. Since the atoms in organic molecules tend to be nonmetals‚ then the bonds that hold them together are covalent bonds. Only a few elements on the periodic table are nonmetals: C‚ N‚ O‚ S‚ Cl‚ and F. This small number of elements can be bonded together in different quantities‚ bonding types (single‚ double‚ triple bonds)‚ and structural

Rolling. b. Forging. c. Drop forging. d. Heading. e. Hot pressing. f. Extrusion ADVANTAGES OF HOT WORKING PROCESSES Advantages of hot working process (i)Due to refinements of grains‚ mechanical

Nucleation As in solidification‚ nucleation occurs most easily on surfaces already present in the structure‚ thereby minimizing the surface energy term. Thus‚ the precipitates heterogeneously nucleate most easily at grain boundaries and other defects. Growth of the precipitates normally occurs by long-range diffusion and redistribution of atoms. Diffusing atoms must be detached from their original locations (perhaps at lattice points in a solid solution)‚ move through the surrounding material

The Purity and Purification of Solids Melting Point Lab Introduction: The point of this lab was to determine the eutectic point for the naphthalene biphenyl mixture‚ as well as determining the melting point of an unknown substance by comparing it with two known samples. Melting point is a temperature in which a substance changes from solid state to liquid state. Melting points are used to determine whether the given substance is pure or not. Substances that melt sharply‚ less than 1-2°C indicates

Oxidation of Cyclododecanol Bo Schuetz Chem 34l Section 004 10/29/2024. Introduction Goal: The objective of this experiment was to convert cyclododecanol‚ a secondary alcohol‚ into cyclododecanone‚ a ketone‚ through an oxidation reaction using sodium hypochlorite (NaClO) as the oxidizing agent. Oxidation reactions of alcohols are fundamental in organic synthesis‚ as they enable chemists to selectively introduce new functional groups‚ which can subsequently be used to build more complex molecules

Distillation Introduction: The recrystallization technique you learned last lab is a method for purifying solids. This week we will learn how to perform a distillation‚ a method for purifying liquids. Distillation is a common wet-chemical technique for separating organic compounds based on differences in boiling points. Upon heating a mixture of organic compounds‚ the more volatile compounds (those with the lowest boiling point) will vaporize first (i.e. be converted to gases)‚ leaving the higher-boiling
