<p>[QUOTE=&quot;mrbrklyn, post: 215122, member: 4381&quot;] <ol> <li><br /> <br /> <br /> Esthers are just a subgroup of aldehydes and both are active.&nbsp; I spent a good part of my PhD studying them.&nbsp; <br /> <br /> Aldehydes, ketones, organic acids and esther bounds and all derived from each other and can be thought of as related through derivites of the carbonyl grouping.<br /> <br /> They certainly have basic and acidic as well as oxidative properies unless your not a believe in vinegar.&nbsp; The (=0) is an inherent Lewis acid.&nbsp; The related Acetonitriles have made a bit of news lately.&nbsp; <br /> <br /> This has little to do with Coins, but dipping silver in acetone clearly has a chemical affect.&nbsp; Mind you I was not trained as Chemical Engineer, just a Physical Chemist in Drug and Medical research, or Pharmacuetics.&nbsp; We don&#039;t run the same reactions over and over but had to devise new models for the technology of identifying new chemical entities, discovering such entities in the first place, purifying them and delivering them safely to human and animal populations, laying down the ground work for the Chemical Engineers.&nbsp; Therefor my perspective might be a little skewed.&nbsp; I see everything as reactive, especially something that is the building block for the vast majority of reactions and materials which are studied and used today.&nbsp; Is Acetone &quot;relitively&quot; inert.&nbsp; I&#039;m not certain of that at all.&nbsp; It took years to determin that Nylon was safe.<br /> <br /> Ruben</li> </ol><p>[/QUOTE]</p><p><br /></p>
