Similarly also have used vacuum cycling technique by applying and releasing in short bursts several times appeared to work just as well and was easier to implement in a few tanks that had appropriate valve configurationsAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8964719845369935777.post-83603898627078313592013-03-27T20:23:52.554-04:002013-03-27T20:23:52.554-04:00I think that if your reactor is cold enough the fo...I think that if your reactor is cold enough the formation of aerosols should not be a problem. Solvent loss can easily be avoided by running your condensers at -25°C. The last time I did one of these we did not bother removing dissolved oxygen and everything worked just fine. Their process must be very sensitive to oxygen. Anonymoushttps://www.blogger.com/profile/15287977920784124907noreply@blogger.com
