I never got a full conversion with the short reaction time and low amount of zinc bromide. It always ended up like 40%d9 20%d8 and like 30% unconverted CBD.
After talking to @Roguelab and increasing zinc bromide amount, adding zinc chloride and increasing reaction time it went up to around 65% d9 with rest d8 and minimal CBD.
This sounds pretty similar to someone else I won’t mention that I purchased a d9 sop from for 10k. First price was 20k but the person was talking about investors that were going to pay around 200k to exclusively use the process for 6 months first. Long story short price was dropped to 10k and the sop didn’t work nearly as well as advertised.
oversell and under-deliver is the industry way
