<p>[QUOTE=&quot;desertgem, post: 1604452, member: 15199&quot;]I have read that article cited and my complaint is that no indication of the amount of water vapor, the intensity of the ambient light, the treatment of the foil before testing, why they allowed the acetone solution to remain until evaporated, thus concentrating any acetic acid, and also why was it not done in sealed containers to eliminate any other chemicals that might be in the air of the lab and concentrated by the drying. </p><p><br /></p><p>I do not disagree that photolysis of acetone might occur, and that acetic acid formed, but I certainly have never recommended the conditions they used with their experiments. Actually my opinion is that it was a poorly done experiment, IMO.</p><p><br /></p><p>I beg to differ.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
