POLYMER SYNTHESIS AND PROPERTIES AIM: The aim of the experiment was to prepare three different polymers‚ namely nylon 66‚ Agar Gel and slime‚ being able to differentiate between the configuration and analysis among the three structures‚ noting the physical characteristics of each polymer and the chemical reactions that occur during the formation of the polymer. Pre- lab questions 1. Is Nylon 66 a step or chain – growth polymer? Define both types of polymerization in your answer. Nylon 66

Abstract: Cajanus cajan (L.) is one of the Pigeon pea cultivated in tropical and subtropical areas. It contains many fractions characterized by their bioactivity and efficacy to enhance biological activities. The aim of the present study was to fingerprinting the Cajanus cajan plant ‚ then extract the flavonoids fraction (FFCC) with methanol extract‚ and assess the antimutagenic efficacy of the fraction extract to reduce genotoxicity induced by cyclophosphamide (CP) using chromosome aberrations‚

! Isolation of the Components of BC Powder Introduction Aspirin‚ Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this‚ the three components were forced into conjugate acid (or base) forms‚ causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel

The objective of this experiment was the synthesis of Isopentyl Acetate using an esterification reaction between acetic acid and Isopentyl Alcohol‚ using a strong acid as a catalyst. The product was washed‚ and distilled. This approach is called Fisher esterification‚ whereby esters are produced by the esterification of a Carboxylic acid where it is heated with an alcohol in the presence of a strong acid which acts as a catalyst. The ester produced had a banana flavor. The extraction of the
