today I try again.
after boiling with HCl for two hours, I separate layers.
keep the black layer and basified to ph14 keep it mix for an hour .
then leth it rest for 6 hours and remove the water layer .
after this I add toluene to the black layer but no layers form
and product destroyed.
toluene smells exactly like thinner
