Resorcinol from tree sap

Random - 15-10-2010 at 07:36

I have some tree sap from firs and could I make resorcinol from that? Or maybe extract some other useful compounds? I have about 1 kg of that tree resin.

I forsee a nasty mess in your future

I see sticky stuff sticking all over everything, it will be vile :(

Its not that bad actually, I easily manage to clean it using MEK and isopropyl alcohol nail polish remover. :) Just is there a way to do it?

Make it from tree sap? industrial production is by fusing
benzene-m-disulfonic acid with sodium hydroxide.
{CCD}

Tree sap may depending on the species of tree heated with sodium hydroxide may work.

Or maybe extract some other useful compounds? .


Sure destructive distillation of the whole plant works. Useful .....?

Maybe extraction with hot aq. NaOH does work. Precipation with aq. HCl may lead to a crude product.

Sez — is formed on fusing various resins, such as galbanum and asafœtida with potash....
Wiki-P sez the same.

Question being — why were these two gum's/resins preferred?

It's actually pine tree resin. Do I need to fuse it with NaOH or I can just use solution of naoh in hot water?

Resorcinol is obtained in considerable quantity by distilling extract of Brazilwood, a dye made by boiling the wood of Cceialjrinia braziliensis with water, and evaporating the solution. It was originally prepared by fusing with potash the gam-resin known as yalbanum, obtained in Turkey and the East Indies as an exudation from the Galbanum officinale, an umbelliferous plant. Other gum-resins obtained from plants of the same order also yield resorcinol when fused with potash; such as ammoniacum, atsafcetida, tagapenum, all more or less firt idsmelling medicinal bodies imported from the East. When these gam-resins are distilled alone, they yield umbelliferone, C.H.O,, or CaH,(CHO).,CO, which is converted into resorcinol when fused with potash.
