Question Safe temp to evaporate water (codeine water mix)

[jizzyspanner]

Hey guys, I have a bunch of water with codeine dissolved in it (cwe) and I would like to evaporate the water to get the codeine powder. I have read that heating codeine can damage it which I ideally dont want to do. Is there a temp that I can get the water to to evaporate the water without damaging the codeine? Is there any other good ways to achieve what I want to do without heating it? Thanks in advance

the three major opium alkaloids are relatively stable. At 120 °C, minimal, if any, alkaloid degradation was observed after 120 min. With the experimental temperature at 200 °C, the half-life of morphine and codeine was found to be approximately 32–39 min, while thebaine was only 3 min. As a comparison, a previous report found that 80–90% of morphine and codeine degraded after 20 min at 220 °C

oh ok that makes sense then why people can smoke opium and heroin and it still hits them? So if i get an oven tray out or something wide and flat and heat it to 100 i should be alright? i can still keep the water fairly minimal to ensure quick evaporation
