My yield from 180 g safrole was 140 g distillate. I have figured, though, that I loose most of my yield during distillation. Before I distilled, I had 170 g of rather pure looking oil in the flask (wine red color, but transparent, as opposed to black and gooey). When I fractionally distilled the 140 g of distillate to purify it, I lost 5% to the distillation. Also, the distillate I collected is really fucked up. Instead of one peak corresponding to ketone, I got two. One was around 120C and the other around 150C. Neither was safrole. I even took drip rate vs. temperature data and plotted a graph. The graph showed that there were two peaks in the collection as well. My theory is that both of these peaks are relatively pure ketone, but one of them (probably the higher one) is an azeotrope that the ketone forms with either its polymer or some unhydrolyzed acetal. I suspect this, because I have found that the acetal forms a minimum azeotrope with safrole, even in very small quantities. The lower fraction was pale flourescent green (like lemon-lime powerade) and the higher fraction was more like piss yellow. Both fractions were about equal in size. I have yet to aminate it, as I am trying out a new procedure for then amination and need to perfect it first. I would post the graph I made, but I don't know how.
