Crystalline Freebase Conversion of DMT

Though heptane is a bit more toxic and more difficult to evaporate than acetone, it is able to achieve a more pure, hard, crystalline product. The only likely potential impurity--assuming proper decanting--is residual heptane. Mix DMT fumarate with an equal amount of sodium carbonate and moisten thoroughly. Allot adequate time and stirring for complete reaction. Add enough warm heptane to completely submerge material and allot adequate time and stirring for dissolution. Decant heptane into a small open glass vessel and allow to evaporate with or without airflow. The resulting product will be crystalline with some leftover oil that may be recycled. acetone works well for recycling uncrystallized product. Air-dry material thoroughly before storage. Continue to pull with warm heptane until material is apparently exhausted. Store in a cool, dark place in a sealed container, preferably protected from moisture and oxygen.
