For example, a popular demonstration of interfacial polymerization the " nylon rope trick " is the synthesis of nylon 66 from adipoyl chloride and hexamethylene diamine. C They are made from petroleum and natural gas. Hydrolysis is faster at higher temperatures. For example, mutations in CYP2E1 increase activity and result in increased generation of toxic metabolites.
But what use were short glass fibers? Benzene is sufficiently nucleophilic that it undergoes substitution by acylium ions and alkyl carbocations to give substituted derivatives. B They can conduct electricity. Heated to °C, the salt reacts to form nylon polymer. Nylon is a generic designation for a family of synthetic polymers first produced on February 28, by Wallace Carothers at DuPont. Because the acid is acidic and the amine is basic, they first react together to form a salt. Heated to °C °Fthe salt reacts to form nylon polymer with the production of water.
These are formed into monomers of intermediate molecular weight , which are then reacted to form long polymer chains. D all of the above. B less than 40°C but greater than 0°C. Retrieved 31 March In the second case so called AA , the repeating unit corresponds to the single monomer. The new understanding of benzene, and hence of all aromatic compounds, proved to be so important for both pure and applied chemistry that in the German Chemical Society organized an elaborate appreciation in Kekulé's honor, celebrating the twenty-fifth anniversary of his first benzene paper.
