    The identification of the peaks was carried out by comparing the retention times with those obtained with a standard solution of all-trans lycopene. The quantification was performed using the relative area under the curve. Lycopene extracted using n-hexane as a solvent at 65°C was also characterized for its extraction efficiency with respect to the quantity and quality and compared with those obtained using the optimum conditions of SFE. 3.5 Comparative varietal

    components of the mixture that consisted of 50% benzoic acid‚ 40% benzoin‚ and 10% dibromobenzene. The benzoic acid was extracted by the use of base and extraction technique. Then a crystallization was performed in order to separate benzoin by the use of hexane a solvent‚ leaving the dibromobenzne in the mother liquor. The percent recovery for benzoic acid was 91.8% and 80.3% for the benzoin. The MP for benzoic acid was 119-122°C (1) and 135-136°C (2)for the benzoin. The high percent recovery and closeness

    experiment that will give enough data to rank the three halogens from highest to lowest electron affinity. Background: The three aqueous solutions given in this experiment are Iodine‚ Bromine‚ and Chlorine; they are all non-polar and dissolve easily in Hexane which is also non-polar. When there is a color change in a mixture that means that it reacted and that there was a double displacement reaction when there is no change then it didn’t react because it isn’t possible. Cl2 + 2NaBr  Br2 + 2NaCl Cl2

    point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting point. Boiling point determination was done on 7 different test compounds using micro method. Results show that propanoic acid and n-hexane had the highest and lowest boiling point respectively. The former had the strongest intermolecular force of attraction among the test compounds. Thus‚ there exists a direct proportionality between intermolecular forces of attraction in a compound
