Meconin dissolves in 265*7 pts. of cold, and 18'5 pts. of boiling water ; in alcohol
and ether it is still more soluble. It is dissolved by the fixed alkalis, but is nearly
insoluble in ammonia. When heated to 100° with aqueous ammonia, it yields a ...

By mixing ordinary opianic acid with a large access of potash-ley, and
evaporating the liquid nearly to dryness, meconin and hemipinic acid were
produced. This decomposition, in efl'ect, is simply a rearrangement of the
constituents of opianic ...

The barely possible supposition that the additional quantity of meconin is owing
to the reduction of hemipinic acid formed in a previous stage of the reaction, is
excluded by the fact that hemipinic acid is not acted on by sodium-amalgam in ...

in view, the reaction must be stopped long before the whole of the narcotine has
been decomposed ; meconin, on the contrary, undergoes no change under these
circumstances. As has been previously observed, when crystallized narcotine is ...

When the heat approaches the boiling point of water the meconin assumes the
appearance of colourless drops of oil, which gradually dissolve.' Sulphuric acid,
diluted with half its weight of water, dissolves it without the assistance of heat.
The authors, on Tepeating the experiments of Matthiessen and Foster, of fusing
opianic acid with caustic potash, found that, as they had stated, it was converted
into meconin and hemipinic acid, but that the latter contained a small quantity of ...

Couerbe, to obtain meconin, omitted the treatment with baryta, and merely
evaporated to a syrup, after precipitating the morphia and narcotine with
ammonia: after fifteen or twenty davs meconin and narcein crystallised together.
William Crookes, James H. Gardiner, Gerald Druce, 1863
