i started with 10g cas 5449 in 20g water, after adding hcl acid to ph 1, the bottom yellow layer appeared, it did not float to the surface and was red like other reports, i continued heating for 1 hour and it appears more oil, I want to ask if this oil can be used to do the next step without further refining?
Stirring is important. Red color is a very bad sign as this is polymerized P2P. P2P has a density of 1,02 g/ml, so it is heavier then water. Except the water contains enough of something what makes it heavier. Like the salt formed when you add the acid. If you used a lot of water - what is very good - the density of water and P2P might become to similar to separate properly. Add more salt - NaCl - dishwasher regeneration salt - and P2P wioll go to the top. Or add solvent at the end. If your oil is clear and has only a slightly yellow tint then its good enough to be used in the next step directly. Otherwise distill or steamdistill.
