This is an unknown organic compound.
As what you can see in the picture, its light brown or near to
gray color. Its solid, but not powder, it is almost a little piece
of solid.
The odor of it is almost no smell or a little bit of smell of
wood. The flaming for this compound is just normal yellow fire, and
there is nosooty.
The m.p. of it is around 113.7~115.8 ??
This solid is insoluble in none of...
