is to convert carbonyl compounds to alkenes using Wittig reaction. In this case we will be synthesizing Trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde. We will also aim to obtaining a high percent yield and purity for the synthesis of Trans-9-(2-phenylethenyl) anthracene. The mechanism for this reaction goes thus: Experimental: Benzyltriphenylphosphonium chloride (0.201g) and 9-anthraldehyde (0.116g) were weighed and

Introduction: The purpose of the first experiment was to practice obtaining accurate and precise results by doing combustion analysis to find the amount of carbon dioxide and water released and the amount of fuel consumed. To identify the amount of carbon dioxide‚ water and burner consumed there were three equations used to find it. Equation 1 shows how much carbon dioxide was released. Mass of carbon dioxide = m2 - m1 Equation 1 was used as an experimental procedure created to help find out

ABSTRACT The task of designing a mechanical component with design software then reverse engineering the same component in hyper mesh was assigned to groups. The engineering component chosen by group 10 is a piston for standard automobiles. The design is then accessed and redesigned for the primary purpose of improving the product. This group 10 the principle area of improvement is the weight‚ to achieve this‚ the initial material choice for design medium carbon steel is changed to aluminium alloy

Tensile Strength; The (ultimate) tensile strength is the level of stress at which a material will fracture. Tensile strength is also known as fracture stress. If a material fractures by ’crack propagation’ (i.e.‚ it shatters)‚ the material is brittle. Yield Stress; On a stress strain graph

Stretch forming is performed on a stretch press‚ in which a piece of sheet metal is securely gripped along its edges by gripping jaws. The gripping jaws are each attached to a carriage that is pulled by pneumatic or hydraulic force to stretch the sheet. The tooling used in this process is a stretch form block‚ called a form die‚ which is a solid contoured piece against which the sheet metal will be pressed. The most common stretch presses are oriented vertically‚ in which the form die rests on a

determine and compare the Modulus of Elasticity‚ Yield Strength and Yield Strain on four different materials using a cantilever beam and vernier calipers. Background -Plastic Deformation- When a material is permanently deformed after a force is applied then removed. -Modulus of Elasticity- Describes the materials properties to be deformed elastically/non-permanently. This is the slope of the stress-strain curve in the elastic region. -Yield Strength- The level of stress at which material

1. You have a cash obligation of $132‚240 to be made at the end of year 5. Show how you can use coupon bonds with a coupon rate of 8%‚ a face value of $1‚000‚ a maturity date at the end of year 6‚ and a yield to maturity of 8% to ensure that you can meet your cash obligation at the end of year 5. Suppose that you purchase the bonds at the beginning of year 1 and that the market interest rate changes only once right after you have purchased the bonds. There are three possible interest rates‚ 7.9%
