Alcohol is frequently used in the lab. It can be used as a solvent, a cleaner, or just to get through the day because you hate your job and coworkers so much.

You simply pulverize your transport problem in a mortar with a porcelain pestle, transfer the dust into an Erlenmeyer flask, add 80 percent neutral grain alcohol and watch your transport problem dust solve into a clean, flower-scented liquid. You can then perform fractional distillation of the transport problem solution to obtain all the bright ideas contained in it, because bright ideas behave as volatile aromatic compounds.

I'm so glad I discovered your videos. Chemistry, atomic science has always been a great interest to me. This video in particular gets me more curious as to how people get addicted to putting poisons into our bodies. I used to be a addicted to alcohol. I know many people would say "you are always a recovering alcoholic" because of the fear that the fight is there to avoid temptation but the thing is my temptations for alcohol are completely gone because of chemistry as well do to a little other chemical in the form of a drug called Topamax. First time I took this drug proscribed to me by my doctor, something in my brain clicked that completely rid me of wanting alcohol and made me feel that alcohol is as bad as heroin. I only took Topamax for a very short time and it was not addicting and now I have zero desire for alcohol. I've been alcohol free for more than 5 years and I realize now that even casual drinkers are addicted to alcohol no matter if they think they are not and argue the fact I was there and now I understand. Thanks for all of your great videos. I enjoy every single one of them and want more.

I noticed he said "the only way to break it is by adding a third compound". This is not true, they use pressure swings to break the azeotrope. So instead of boiling the water off of the alcohol, they raise the pressure, and then boil the alcohol out of the water to obtain pure alcohol.

great video :-) I myself make apple wine but it's interesting to see the chemistry in a periodicvideos video. Preventing that you get vinegar is very important, thats why all equipement always must be sanatized.So that you can minimize unwanted bacteria. However wine always contains acids, depending on what your fruit was, it can be oxalic acid (rubarb wine), tartaric acid (grapes), Malic acid (apples) and lactic acid. Controlling the acidity of the wine is also a topic in wine making :)

Dear Sir Martyn, you think you have a disadvantage when you come to a country where beer drinking is a big tradition? I live in one: Danmark (or "Denmark" as it it is often called abroad for reasons that I don't quite understand) - the homeland of Carlsberg beer which is featured in this video. And I also don't like beer. But I do not consider it a disadvantage at all, as nobody forces me to drink it. (Sometimes some people have tried to convince me of the virtues of beer or even tried to persuade me to have some, but I've always been completely immune to that.) By the way, I also don't like coffee. In fact i dislike it much more than beer. And coffee is just as big a tradition in my country as beer is. I belong to the probably around 5% who prefer tea. When I'm with people who don't know me very well, and I reach for the teapot, they often shout: "Look out! It's tea!!", as if it was some kind of poison. I usually thank them for their consideration, and answer with a smile that I would much rather have a warning if I should accidentally reach for the coffee pot!

A few years ago, one of my roommates made home brew beer in a 30 L conainer in his room for christmas, and it was of decent quality (with high alcohol content), but he only drank half of it. After christmas, he destilled the remaining 15 L with a home chemistry set similar to what you used, and got out about 1,5 L of ethanol + traces the first round, but proceeded to destill it twice more and ended up with about 1 L of ~90-95% ethanol without foul taste, and mixed drinks with it.

When this distillation was performed it was more complex than just heating it to 78c to get just the ethanol to boil off. The distillation head was creating reflux. By watching the thermometer and keeping the heat low enough to keep it at 78c the vapor was refluxing at just the right rate to allow only mostly pure ethanol to be condensed in the liebig. The vapor that comes off of a boiling mixture of ethanol and water will contain a certain percentage of ethanol and water which is determined by the concentration of ethanol present in the boiling liquid. Only through reflux or repeated batch distillation can one obtain a high concentrations of ethanol from a weak mixure such as is present in beer.

The thing about a simple distillation like this is that, as the lighter and lighter fractions boil off, the boiling point of the pot rises. A little bit of this was shown in the video, but the interesting thing is that if you were to plot temperature with time, you'd find a little plateau for every component in the beer. What's in there isn't just water and alcohol, so the temperature rises slowly as the lighter aromatics come off, then you get a nice long plateau for the alcohol, then it jumps up again a little bit when the alcohol is gone and some of those heavier compounds start coming off. Getting just the alcohol part of the run without getting the heavier and lighter stuff is what makes this more difficult than it looks at first. Perhaps the professor should do a field trip video at Glenfiddich? It would give an opportunity to talk about reflux too...

It was very useful to have found your channel recently and have been learning a few things from it. On the topic that when ethenol in wine is exposed to some bacteria they would turn some to acid thus making it sour. When this happen, we would usually say the wine is spoilt and we would notice it quite fast. However, would the same happen to a bottle of whisky or brandy ? Most people would not finish a bottle of whisky immediately after it has been open. In my experience, I do not taste the whisky turning sour even when the remainder is left in the bottle for a period of time.
@jayl9110
@jayl9110 Жыл бұрын
If my understanding is correct (and it may well not be) that sourness comes from acetic acid - vinegar. It's done by a specific bacteria which I suspect can't survive at the high EtOH concentrations in spirits, but I'd be interested to do some experimentation to find out exactly what the threshold is.

It's very easy to see how that all works when the product is a nice wine or beer.

There is a mistake concerning the explanation of how the distillation works. When you boil a mixture of liquids, the vapor created contains ALL of them, although in a different proportion. In this case, the vapor will be richer in ethanol than the liquid, but it will still contain a high concentration of water. This concentrations come from thermodynamic equilibrium. In any case, through a simple distillation you cant come even close to the azeotrope composition. In fact the distillate is mainly water. To reach the azeotrope you need succesive distillations or fractionate distillation (usong a tower with reflux and packing or trays). This sort of misconceptions about the mechanism of distillation are surprisingly common among chemists...

This is fractional distillation since they kept the temperature below 100C.

wcg66 They did a simple distillation. A fractional distillation would have involved the use of a fractionating column. The OP is correct. In a simple distillation the result will be more pure, but nowhere near the azeotrope.

My friend showed me that if you put your finger in your ear then in your beer, it will make any foam that is on it almost instantaneously disappear! The reaction between the ear wax and the beer foam is pretty cool. Good way to stop overflow!

Very informative. I'm trying to figure out a cheap way of distilling a high purity ethanol. Unfortunately, my state banned 190 proof liquor, and it seems like I can't find isopropanol above 70%. I used to often use 90+% alcohol for cleaning purposes, and I need it for photography chemicals.

they do plenty of experiments, from co2 reclamation and purification experiments(co2 and concentrated yeast culture that is siphoned off the fermentation tanks to reduce pressure, the amounts of co2 given off at that scale can be lethal in a room) worked with the industrial control section at carlsberg fredericia for a bit.

When I first made an ethanol model (using that same kit!) I immediately called it "ethanol puppy", and was quite entertained by it for at least the next 3 weeks, even bringing it to class and putting it on my desk during an exam, although, the more realistic staggered conformation is a bit more PG-13.

When distilling beer, does none of the oils and/or terpenes come over before the water boils? In other words, are there any hops left over in that beer alcohol?
