      • Nitroglycerin Synthesis and Detonation

        In this video, the high explosive nitroglycerin is synthesized. It is then detonated in two different ways. Nitroglycerin is the active ingredient in dynamite and has applications in medicine. A significant shock will cause it to detonate. The stack of paper which was destroyed by the final, large reaction was a copy of the USA PATRIOT act. While others were debating burning the burning of Qur'ans, we were celebrating our freedom on the anniversary of 9/11/2001 by blowing up a true threat to it. The nitric acid was made following the synthesis in one of our earlier videos on Youtube. Sulfuric acid can be bought as a brand of liquid drain cleaner, and 99.5% glycerin can be bought as "skin protectant" from Wal-Mart. Sodium bicarbonate is common baking soda. Sulfuric and nitric acids are both very caustic and toxic. Nitroglycerin is a powerful explosive which is quite shock sensitive. It can be absorbed into the body through vapors and skin contact and causes severe headaches known as "NG head." Perform this experiment outdoors. Always wear gloves and goggles. Avoid breathing any fumes. The following is very important: do not drop your flask of nitroglycerin! There are two important things we would do differently next time and recommend that you do as well. First, we would pour the reaction mixture into a larger quantity of colder water. The exothermic solvation of the acids increased the temperature to a point very close to where nitroglycerin begins to decompose. Second, we would have used a second water bath to further reduce the acidity of the nitroglycerin. This would have made the sodium bicarbonate rinse go smoother. The reactions seen here are: C3H8O3 (l) + 3*HNO3 (l) → C3H5N3O9 (l) + 3*H2O (l) (catalyzed by large amounts of H2SO4 (l)) 4*C3H5N3O9 (l) → 6*N2 (g) + O2 (g) + 12*CO2 (g) + 10*H2O (g)

          Tuesday, September 7, 2010 - Several Chicago-area women business leaders hosted 8 Taylor University female chemistry students at Edlong Dairy Flavors, Elk Grove Village for an "Exploring Opportunities in the Chemical Industry (Food Science Technology)" career day. Laurette Rondenet-Smith, CEO/COB, The Edlong Corporation, a food flavor manufacturer; Lori Hilson Cioromski, President, TH Hilson Company, a specialty chemical distributor; Jennifer Wolfe, President Wolfe Photography; intended to impact a young person's life in a profound way. Taylor University students learned about the sales process in how a new chemical is introduced, the testing and approval process, participated in a sensory tasting panel and went on a pilot plant tour at Kraft Foods to see how food flavor ingredients were blended into the finished product which will eventually be available on grocery shelves. "If we can encourage one student to gain insight on future career opportunities, then we will have accomplished our goal to make a positive difference in a young persons life." said Hilson Cioromski The National Association of Women Business Owners (NAWBO) started a group called Next Generation Outreach (NGO) to reach out to young adults that might not have been given opportunities because of race or economic conditions. "There are many young women who want to have a business or to have their own sense of independence but do not know how to go about doing it, so that is where we come in" says Patti Ernst the chairperson for NGO. "This group bridges the gap between ideals, need and education" says Ida Manning, the Executive Director of the Illinois Institute for Entrepreneurial Education (IIEE) who works to bridge the gap between education and businesses.

                Helen Fisher, one of the world's leading experts on romantic love, identifies four broad personality types, each governed by different chemical systems in the brain. Love is no longer blind, thanks to pioneering scientific research, based on her unique study of 40,000 men and women. Fisher explains each type, shows you how to identify your own type, and helps you use nature's chemistry to find and keep your life partner.

                  Disappearing ink. Trick birthday candles that relight after extinguishing. Pulling an egg through the mouth of a bottle without breaking it. These tricks seem to defy the laws of nature, but they’re not magic. Let’s apply a little chemistry to reveal the mysteries behind these magic tricks.
