PMK Oil Synthesys From PMK (CAS 28578-16-7 Wax Form) Large Scale

Hello,
Firstly I don't think you created that process, in fact I had this similar info long time ago from Chinese suppliers, anyway I made some changes as you can see.
Sodium bicarbonate is a softer washing method and in this case is safer to use it to avoid to damage the product.
About DCM obviously I mean to separate the bottom layer(DCM layer) and evaporate it sorry if my explanation is not clear.
To avoid water after separate layers you can dry it with anydrous sodium sulfate and filter it before evaporate the solvent( in fact I always do it in all my processes)
Thanks.

Hi everyone, sorry but is the starting material here, this PMK wax. Is this just Paraffin Wax, Piperonyl Methyl Ketone PMK? Or is this PMK wax something completely different? Thanks 
Sorry I’m new here. Can anyone answer two questions
Using CAS 25785 (pmk glycidate oil) then adding naOH, then adding sulfuric, oxalic, and citric acid over time and washing with H20, bi carb, brine, and vacuum distillation
1) what color should it be? Mine is a beautiful red color. Clear.
2) what does it smell like? Mine smells like…idk? Chemicals? But kinda sweet?
thanks in advanced

I don't know the process that you follow with that products but normally is a yellow-brown oil depends of PMK manufacturer too the best one I use the final oil is yellow.

230 g pmk
Added to 300ml 16% naOH solution stired 2 hours
20%sulfuric acid 100 g citric 60 oxalic mixed cooled and added 30 mil at a time
Cooled to 30c added xylene until waiting until oil separated to tooe
H20 washes and bicarbonate washes if that helps

Without heating and reflux?
And it works? Yield?
Interesting if it works but difficult to make the processes needed in good way without heating.

Pardon 28578, same one you’ve written about.
yes heated in base phase and acid.
And heated during vacuum

Is it possible to substitute DCM for Toulene?
Sadly I'm in a country where DCM is heavily watched
Hello, I'm a beginner.
I would like to inquire in section 6.
6. Add 3,25kg of HCL 37% in small portions, once all added keep the mixture at 80 °C reflux during 1 hour stirring.
Can I use Hydrochloric Acid 35% instead of Hydrochloric Acid 37%?
