Here is swims recipe using Acacia Confusa, either phyllodes or bark, not sure yet, how does it sound? Does anyone know if Diggers branded Xylene is a good choice? What makes a good choice for Xylene? Or is it dissimilar to say Shellite, where you do an evap test to deduce whether you should use it or not.
ACID COOK
Place 50g bark in a jar.
Add 500 mL water + 10 mL of 10% HCl.
pH check, should be 2–3.
Stir. Cover loosely.
Soak 24 h at room temp. Stir 2–3×.
STRAIN
Pour through a coffee filter into a clean jar.
Squeeze bark solids. Discard solids.
XYLENE DEFAT (×3)
Add 100 mL xylene to the acidic solution.
Gently roll end-over-end for 2–3 min.
Let layers separate (5–10 min).
Discard the top xylene layer.
Repeat 3× total. Stop when xylene comes off clear.
BASIFY
Dissolve 50 g NaOH in 200 mL warm water.
Slowly add to the acidic solution, stirring.
Check pH after each addition.
Stop at pH 11–12.
Add water to bring volume to ~500 mL.
Cover. Soak 24 h. Stir 1–2×.
XYLENE PULL (×3)
Add 100 mL xylene to the basified solution.
Gently roll 2–3 min.
Let layers separate (10–15 min).
Pour off top xylene layer into a clean jar.
Repeat 3× with fresh xylene.
Combine all pulls in one jar.
Discard the water layer.
BACKSALT
Add equal volume of dilute acid water to the
combined xylene pulls.
(500 mL water + 5 mL of 10% HCl. pH ~3.)
Gently roll 2–3 min.
Let layers separate (10 min).
Discard the top xylene layer (oils).
Keep the bottom acid water layer.
RE-BASIFY
Slowly add NaOH solution to the acid water, stirring.
Stop at pH 11–12.
Add water to ~300–400 mL.
Cover. Soak 24 h. Stir 1–2×.
HEPTANE PULL (×3)
Add 100 mL n-heptane to the re-basified solution.
Gently roll 2–3 min.
Let layers separate (10–15 min).
Pour off top heptane layer into a clean jar.
Repeat 3× with fresh heptane.
Combine all pulls.
Discard the water layer.
FREEZE PRECIP
Pour combined heptane into a shallow glass dish.
Cover with plastic wrap (not sealed).
Freezer (−18°C) for 24–48 h.
While still frozen, carefully decant the heptane
away from the crystals.
If decanted heptane is still yellow, re-freeze 24 h
and decant again.
