aMicroscale Synthesis of Isopentyl Acetate (Banana Oil) Objective: Carried out the microscale synthesis of isopentyl acetate by direct esterification of acetic acid and isopentyl alcohol. This was an acid catalyzed Fischer esterification. Both extraction and distillation were employed to obtain a pure product. IR spectroscopy and gas chromatography were used to determine purity of the final product. Reagents: * Compound: | * MW (g/mol): | * MP (°C): | * BP (°C): | * Density (g/mL):

Rayon is a manufactured regenerated cellulose fiber. Because it is produced from naturally occurring polymers‚ it is neither a truly synthetic fiber nor a natural fiber; it is a semi-synthetic[1] fiber. Rayon Fiber Characteristics o Highly absorbent o Soft and comfortable o Easy to dye o Drapes well Some Major Rayon Fiber Uses • Apparel: Accessories‚ blouses‚ dresses‚ jackets‚ lingerie‚ linings‚ millinery‚ slacks‚ sportshirts‚ sportswear‚ suits

Spinach was dehydrated using ethanol‚ and the pigments were extracted with dichloromethane. The spinach extracts were dried using CaCl2. Then‚ the solid pigments were run through a column using a non-polar solvent‚ hexane

process components. Synthetic thread includes both monofilaments and multi-fiber filaments. Synthetic fibers and synthetic fabrics are made from a variety of materials and may feature a blended‚ fibrous structure produced by copolymerization. Acetate and triacetate fibers are shrink-resistant and wrinkle-resistant. Acrylic and modacrylic fibers are unique among synthetic fibers and synthetic fabrics because they have an uneven surface. Aramid and polyimide fibers are lighter and tougher than steel

Project 1: Polymer Ball Vivian Kim General Chemistry 2045L Introduction Our assignment in this project was to create a bouncy ball for a company using polyvinyl alcohol (PVA)‚ polyvinyl acetate solid and sodium borate‚ by varying the ration of ingredients and to determine the best recipe for our bouncy ball. The company chose the materials because of their odorless and nontoxic properties. PVA is a water-soluble synthetic polymer and has adhesive properties
