    Friedel-Crafts liquid phase alkylation reaction of aromatic compounds is an industrially important which is known since 1877 and also commonly practiced in organic chemistry for the synthesis of various pharmaceutical compounds [1]. Catalytic benzylation of aromatics with benzyl chloride is one of the commercially significant C-C bond synthetic reaction processes to produce benzylated aromatics such as diphenylmethane and substituted diphenylmethanes. These are key intermediates in the synthesis

    CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value

    numbers range from Mn (III) in compounds like Mn(NO)3CO to Mn (VII) in KMnO4. Compounds of manganese range in oxidation number between theses two extremes. This experiment involves the preparation of a Mn (III) complex of actylacetone (also named 2‚4-pentanedione) which is a useful starting material for the preparation of other Mn (III) compounds. Manganese (III) complexes are relatively stable and can be prepared directly by reactions of the hydrous manganese (III) oxide or by oxidation of the hydrous

    studied in this lab was reduction‚ the process of reducing the number of bonds to oxygen and increasing the number of bonds to hydrogen. Other chemical processes included in the lab were recrystallization‚ melting point‚ and extraction. Procedure: Preparation of Vanillyl Alcohol 2.5 mmol of vanillin were dissolved in 2.5 mL of 1 M NaOH solution in a 25 mL Erlenmeyer flask. The flask was swirled to produce a homogeneous yellow solution. The flask was swirled in an ice-water bath for 1-2 minutes and

    distillation techniques: simple and fractional. Simple distillation was done to separate ethyl acetate—which has a usual boiling point of 77º—from a less volatile component‚ while fractional distillation was done to distinguish an ethyl acetate/n-butyl acetate mixture‚ which has boiling points of 77º and 125 º‚ respectively. Results and Discussion As previously stated the standard boiling point for ethyl acetate is 77º. The data obtained resulted with the experimental boiling point being approximately
