 * Procain (Novacaine) **
 * [|__http://chemistry.about.com/od/factsstructures/ig/Chemical-Structures---P/Procaine.htm__] **


 * Uses: A localized anesthetic used in dentistry and procedures involving the injection of penicillin. It blocks the conduction of Na+ in sodium channels. **


 * Major sources: There are two ways to synthesize procain: 4-aminobenzoic acid ethyl ester reacting with 2-diethylaminoethanol with sodium ethoxide as a catalyst, or 4-nitrobenzoic acid reacting with thionyl chloride, which is esterified with 2-diethylaminoethanol, and reduced by hydrogenation over Raney nickel catalyst **

"Polymers in the Field"

After reading this article, I have learned quite a couple of things. One of the most interesting things I learned was about how the field itself is made. When they make the field, they have to do the basics things, like digging the hole, but something that I learned was that they have to add a retention basin, so that the water can penetrate through and be removed from the field. Another interesting thing I learned is that there is a difference between the types of rubber used on the field and on the track. When they make the track rubber, they used a vulcanized type of rubber, for purposes like shock absorption.

Dominic, OK. Good! 5 stars. MW
