For my science fair project‚ I figured out what solvent would work best to erase permanent marker. The solvents I tested were: lemon juice‚ vinegar‚ water‚ and rubbing alcohol. I tried each of these solvents on a permanent marker line on plastic‚ paper‚ fabric‚ and wood. In this research paper‚ I will be talking about what a permanent marker is‚ how they are made‚ why they work so well‚ what rubbing alcohol is and its common uses‚ what vinegar is and its common uses‚ what water is and why water is

Literature Survey 2. Literature Survey Literature survey indicated 135 possible routes for the synthesis of 2-Aminobiphenyl. It must be noted that all routes available were lab-scale and no patents for the desired compound were available. Also‚ majority of these synthesis routes gave extremely low yields of our desired product and produced a number of other by-products in higher yields. Therefore‚ only the pathways giving significant yields of the desired product have been listed below. i. Suzuki
