How do you occupy yourself during a distillation?

RedDwarf - 24-11-2019 at 21:08

Most of my inorganic chemistry or electrochemistry seems to fall into two categories:

1) I need to stay with it 100% of the time during a short period of time

or

2) I just leave it to get on with things on it's own and if it's left an extra couple of hours it probably doesn't matter.

With organic chemistry there's a lot that falls within these two groups and even refluxing can generally just be left for a specific period of time with an alarm on my phone, however distillations always seem to fall outside this categorisation.

The need to change receiver flasks when the temperature starts to change means that it's hard to predict (even when the composition of a simple starting mixture is known fairly accurately) when you need to be there, and watching drops falling into a flask is like watching paint dry:)
So what do you all do with your time when you're performing distillations and the like, how long will you leave unsupervised apparatus and how do you stop yourself getting bored?

1) do other small experiments

2) tidy up and wash glassware etc.

3) reading

4) contemplate life, the universe and everything

Watch chemplayer.

music videos. It helps that I pretty much live in the kitchen/living room, where my lab table is six feet to the right of my couch(daybed), flat screen directly in front of me. Sometimes very advantageous to be a crippled bachelor LOL

I too watch Chemplayer or one of the other top Chemistry video guys eg. Nilered, Nurdrage and of course Extractions and Ire.

a normal distillation for me lasts at least 6 hours (average 10) so i really need to occupy myself otherwise all the daytime is wasted. i usually do other experiments while waiting, i watch some anime/serie, youtube videos, and if i'm really bored and nothing else to do, i try to study for my exams

All of the above & TV shows.

Episodes last about 45mn so it's a good timing to go back and check.
I do also sometimes sleep with an alarm clock set for every hour. Not such a great idea and the source of "what happened here?" now and then.

I wonder if it's possible to wire a digital thermometer to an alarm to alarm you when the thermometer reached a certain temperature?

Yes, I've thought about building an arduino system that could either provide a direct alarm or an alarm on the pc downstairs where I normally work. Unfortunately the idea has only ever joined the queue of potential projects and never got any further than that - perhaps that's something I could be working on during the next distillation, although it's very cold in the room I use (I sometimes wonder if I need to use cooling water in the condenser it's that cold, at least I don't need to use ice in the cooling water!)

For small scale experimental distillations, I would go for music video, exercise, or usual physical work (vacuuming, chopping wood, feeding animals, yoga). Anything that would last few minutes.
For large scale habitual distillations, I would watch episode of some tv series (usually 45 minutes), felling trees, maintaining garden, shopping.
I would try to make distillation habitual and automatic, because safety first.
Maybe by using same volume and time each day.
Excess of liquid, so it never distills completely during one run.
Lack of energy, maybe by charging some batteries and only using them for distillation, or performing it via limited amount of solid fuel (wood, coal). Remember, safety first.

Ya.....dozing off during a fractionation run is not such a great idea. The universe will find immediate ways to administer punishment for such an action :D

One just has to plan ahead regarding the timing (so as not to end up guarding the process in the middle of the night) and force a habit to not trust the system on it's own for long periods of time. Even when failsafes are active.
There are quiet ways that things can go south if one does not keep an eye on the system: sudden fluctuations in atmospheric pressure causing loss of equilibrium in column, bubbles blocking/deblocking takeoff channels and changing the reflux ratio on it's own, silent flooding of column that culminates in a volcanic eruption from the vent channel on top of column, loss of water pressure, failing tube connections, etc, etc. Seen and done it all during the years :)

That's the exact sort of thing Arduinos can be used for.

Hard rock, Rachmaninov, or a nice Jazz Interlude...
