sublimation

Crystals of a sublimed salt.

This is a quite special compound what was made months ago. It was placed in another lab in a small vial and from the heat of sunlight it sublimed on one of the walls of the glass. Why is it special? It’s a salt, like sodium chloride, only difference is, that it has highly fluorinated, fluorous side chain that makes volatile, so it could be distilled/sublimed to produce nice crystals as on the picture.

“… art is a privilege, a blessing, a relief. privilege means that you are a favorite, that what you do is not completely to your credit, not completely due to you, but it is a favor conferred upon you. privilege entitles you when you deserve nothing… art was a privilege given to me, and i had to peruse it, even more  than the privilege of having children. the whole art mechanism is the result of many privileges, and it was a privilege to be a part of it… the privilege was the access to the unconscious… i had to be worthy of this privilege, and to exercise it. it was a privilege also to be able to sublimate. a lot of people cannot sublimate. they have no access to their unconscious. there is something very special in being able to sublimate your unconscious, and something very painful in the access to it. but there is no escape from it, and no escape from access once it is given to you, once you are favored with it, whether you want it or not… to escape you have to have a place to go. you have to have the courage to face risk. you have to have independence. all these things are gifts. they are blessings… sublimation is a gift; lots of people cannot sublimate.”

Stories Which Should Worry My Therapist | Sublimation
A story that never happened about people who don’t exist in an alternate universe where Tom Riddle and Draco Malfoy live and breathe and work together. It isn’t pretty, but then love never is. Or is it hate? And can you even tell when the knife is at your throat and you aren’t backing away, when you’ve dug your nails into your palms and all you can say is, “Please.” AU.

Going through my pictures from this morning, I arrived at this one. You may wonder what’s happening here, and it’s this: the sun shining on the other side of the tree trunk contained so much energy that the thin ice layer on the bark was being sublimated—going straight from ice to steam without melting into water first. These droplets are the steam arising from being ice molecules.

I even took a short (shaky) video of this and could possibly be persuaded to post it.

{among the things for which there are no words: that feeling of finally stumbling across a poem you have searched and searched and searched for, using every combinations of phrases you could recall, and yet can never find. until one day, there it is again, like magic. like it was waiting for you all along}

“We are the strain and stress of a line,
the poem’s tension singing in each black wire
of words, and between the first line and the last.
We are the angle of light that burns water,
the point of intersection that creates perspective.

I’ve never let myself describe you
and now that there’s no time left
your meaning spills out of me
like the essence of an atom cracking
on the edge of speed’s bowl,
liquid in its longing to become part of something else,
transformed.

Last night I Iooked out
to the grocer’s across your street,
baskets of flowers lining the sidewalk,
trembling in the dark wind.
The gasp of paper and leaves
made me eighteen again —nothing about the feeling had changed,
the ambush of longing October calls out.
I’m living proof
we don’t stop wanting
what we can’t have.

No matter where you are or
who you’re near,
we come up for air together.

No matter my pace or distance,
it’s you I surface to.”

- Anne Michaels, fragments from “Sublimation,” in Miner’s Pond (McCelland & Stewart, 1991)

Yesterday I purified a larger amount on slightly decomposed 1,1′-diacetylferrocene by sublimation/distillation at reduced pressure. After the purification, these crystals were left in the still pot.

1,1′-diacetylferrocene is an orange to red crystalline solid, with a melting point  122-128 °C. It is an organoiron compound with the formula Fe(C5H4COMe)2, it consists of ferrocene substituted by two acetyl group on each of the cyclopentadienyl rings. It is an air-stable solid that is soluble in organic solvents and as seen it forms beautiful crystals.

Sublimed, superpure crystals of trichloromethyl-trimethylsilane at the wall of a flask. 

Interesting about this compound, besides it costs much if you would like to buy it, that it has a melting point at 130 °C if it’s sealed, but if you heat it in an open flask, it will sublime away in no time. And it has a quite characteristic odor, similar to camphor.

Why Sherlock is freaking out at the beginning of THoB, AKA, ‘Now shut up and smoke’.

So…  Why is Sherlock so very, very interested in smoking at the beginning of THoB?  Smoking is a metaphor for sex and Sherlock is incredibly hard up for it, so to speak.

John, on the other hand, doesn’t smoke and is having no problems not smoking. As of the middle of ASiB John no longer has a girlfriend and does not get one until much after Sherlock’s, ‘death’.  After his epiphany at Battersea with The Woman John no longer seeks out these desperate attempts at sublimation, he surrenders to what he has with Sherlock, platonic though it may seem.

In ASiB Sherlock seems jealous of John’s girlfriends; of Jeanette in particular since she is his then-current girlfriend and, unpleasantly for him, at their Christmas party.  He seems to have kept careful track of everyone John has dated, better than John himself, even. 

In that same episode it is also revealed that Sherlock seeks to know what kind of porn John watches and actively attempts to prevent him watching said porn.  In THoB when Sherlock talks to Henry he reveals that he reads John’s emails to his girlfriends: poems, apparently.  Here we see Sherlock being very invested and very involved in John’s emotional/sexual relationships/feelings.  In ASiB while John is still dating, Sherlock appears to be keeping his desire in check.  In THoB, now that John no longer has a girlfriend, he is losing his mind.

Part of Sherlock’s deduction of Henry involves smoking: the latter is dying to smoke (as is he) but Henry has not quit, he is allowed to have a cigarette.  And watching him smoke helps Sherlock to sublimate his own desire to do so, 

If we take this situation as symbolic of what’s going on with Sherlock and John, then we can see that when John has girlfriends this creates a sort of outlet for Sherlock.  At least if someone is having a relationship with John then he can somehow live vicariously through them: keeping close tabs on the relationship, possibly imagining himself in the place of his current girlfriend.  Despite his resentment, these women fulfill a very important role in Sherlock’s life, that of proxies.  They also help to neutralise his desire by keeping John unavailable.

I see John’s bisexuality as ACD’s cover for the Johnlock love.  Mary/other women can be his beard(s) but this is made possible only by John’s status as a man who is capable of opposite-sex attraction.  Just as I see Sherlock’s genius as ACD’s cover for their love, it hides a significant amount of John’s love under the guise of, ‘admiration’, and allows Sherlock to have his own mental-beard in the form of his archenemy: Moriarty.  

Later in THoB Sherlock will go as far as to set John up on a date to push this issue.  Things are easier for Sherlock when John’s unavailable just as things are easier for John when he thinks Sherlock is, ‘a machine’.  It’s easier for Sherlock to keep his feelings and desires in check if John is dating.  It’s easier for John to keep his feelings and desires in check if Sherlock is not really human, anyway.

Crystals of sublimed 2-(trifluoroacetyl)pyrrole.

The raw reaction product what was an off-white crystalline compound with a melting point 50 °C was loaded in a test tube and left there for a few months. For now, these crystals formed at the wall what are perfectly pure 2-(trifluoroacetyl)pyrrole.

If this compound is left on a Petri dish for a day, most of it will sublime away.

Purification of a compound by sublimation. 

On low pressures when heated a few compound vaporize from the solid state and could be condensed down as crystals on a cool surface. 

The classic example for sublimation is the sublimation of iodine what could be done at room temperature, but if we use lower pressures, even larger molecules could turn into gas directly from the solid state.

The bottom flask was heated with a heat gun and the condenser at the top was cooled with dry ice/acetone mixture what is at −78.5 °C (−109.3 °F; 194.7 K). As seen on the second picture a small amount of something condensed at the bottom of the condenser as a yellow solid. Hope that it’s what we are looking for.
