Preparation of Samarium Salicylate and Other Experiments
Samarium salicylate was prepared by the reaction of solutions of sodium salicylate with samarium chloride. Upon the addition of the sodium salicylate
to the samarium solution, a white precipitate formed. This gel like material was observed to be lighter in color to the corresponding oxide. When this
wet precipitate was heated, it left behind a black residue.
Further heating of a suspension of samarium salicylate, in dilute hydrochloric acid, yielded a light yellow-green solution which when cooled gave a
white precipitate.
When the precipitate was added to 10% ammonia solution, it dissolved giving a light orange color.
Samarium salicylate has been prepared by simular methods in the past and using aminosalicylate.
------
Samarium chloride was added to a solution of phenol in dry ISPA. A precipitate formed which was confirmed by a control to be phenol.
-----
Samarium oxide was stirred in a weak solution of salicylic acid. No reaction was observed.
----
Samarium oxide was heated with wet picric acid. No detonation was observed, however the picric acid did burn.
Any other recommendations for samarium chemistry?
Tomorrow I may try reacting a solution of picrate with samarium chloride.

Sounds like fun.
IIRC, Sm has a nice flame test.
[edit] Gah! I don't usually make errors like that. Thanks, unionised.

Who or what is Sa?
I'm fairly sure that Samarium (Sm) doesn't give much of a flame test.

When placed into a flame it game an orange color

Everything gives an orange colour- it's due to sodium.

Samarium should give a bright red flame color, approximately the intermediate of lithium's and strontium's. I've witnessed it personally.

Its probably being overwhelmed by the sodium.
Still no luck making samarium picrate. I can not get a precipitate when mixing sodium picrate with samarium chloride.
