you should assume that your viewer has some intelligence, is it necessary to show each step for each lime. Thy adding some informative comment

Is the hexane necessary or could you just separate the oil and water by itself?

13:00 what a tune !

Thank you that was very interesting.

very good

what is EO

What purpose does the loud roaring noise serve?

This doesn't make sense to me, because the solubility at 20 degrees of NaCl and Kcl are almost the same, how can you separate them by filtration if both are practically in the same amount in solution?

lo mejor es el sonido del fondo, es tan relajante, como te envidio, yo aqui lidando con el perro escandaloso y catarro del vecino

High purity is not possible with this method. A mixed salt is actually preferable when used as a feedstock for a chlorate cell. Sodium catalyzes chlorate formation and is easier on electrodes. When the reaction is complete, sodium chlorate is highly soluble and potassium chlorate is almost completely insoluble. So, kclo3 falls out of solution almost 100% pure.

Cheers!

Solvents are never used when extracting essential oils and expecting them to be high quality.

Using hexane wasn't necessary.

How did u make that retort stand ?

why that nitrogen i more acidic than the other one in the imidazol ring? the lone pair is supposed to be involved in the aromatic delocalization while the other one has a lone pair in sp2 orbital i don't really understand, if someone knows please I really wanna understand this point

So whit this method you can separate Kcl from NaCl by diferent degree of cristalization , so the NaCl stay in liquid while the KCl are all formed cristals right?!

This is how mainly essential oils are made. Indeed, industry scale essential oils are distilled continuously. Thus, the solvent extraction step is redundant. Since (purely) solvent extration is another common method to extract fragrances, the products are called 'absolute' instead of 'essence oil'. There are two types of distillation. This video demonstrates water distillation where the raw naterial is soaked in the water. Another one is steam distillation, which is more common, places the raw material on a mesh or any holed container upon a pool of steaming water, and the steam goes through the raw material to extract the fragrances. There is a disadvantage of distillations. There are always more than traces of fragrance dissolved in water. Thus, fragrances of essential oil are often described as 'incomplete' compared with absolutes. The remaining water is not discarded. It calls 'hydrosol', while itself is also somewhat fragrant and is also used in purfumery. Some hydrosols (i.e. rose) can have strong fragrance enough to replace essential oils in some applications. P.S. but there is a bit of epic fail as you use lemon peel for this demonstration. Citrus fruits peel oils are usually extracted by cold pressing without any distillations. But you yet do a good demonstration about distillation❤

can i also use 37% Sulfuric acid? in my country i cant get my hands on higher conc.

Great video! thank you very much! I have a question, perhaps you know this: On all lemon oils I see it is said to be *for external use only*. Why is that? I know that e.g. fish oil is flavoured by lemon oil.

You can speed up drying in your oven using the keep warm setting. I have done it with at 50-60C for about 30 minutes.

Could this be done with a soxlet extractor and ethanol?

What's the name of that stand ? Can anyone tell me?

I try to click the link to buy equipment like this video , but the link is not work properly again..... Colud you please help us , how can we get the equipment / distillator ?

Best outro credit music ever. What's the song called?

Es realmente necesario hacer la separacion liquido-liquido con hexano? En un decantador no se separa ya el aceite del agua?

Why did you need to use hexane as a solvent? Shouldn't the essential oil already be immiscible with the water to begin with?

For oceanography, salinity is determined by conductivity at a known temp then calculated. Salinity is unitless but can be referred as practical salinity units PSU. Common Instrumentation: Guildline 8400B instrument - stable enough to use at sea.

Wait, what is "the global process"? Something you came up with? 😅

The only thing I would do differently is adding a oil/water separator

How about cost of making it, really save or more costly than buy on market

Wow, this is very clean and very knowledgeable! 👍

This is hydro-distillation

Can i just simply separate the water from the oil without using the hexane. Why using solvent at this point?

Hi sir can i talking with you ?plz

I would see a flame coloring test at the end.

Very usefu vedio

Nice

Could you tell me the unit operations performed in the steam extraction of limonene?

5k for equipment, or spend $40.00 on a few ounces on line.

Great video

Ese procedimiento es destilacion simple no arrastre de vapor

Good video and the extraction. Do you have a list of chemicals and equipment used for the extraction?

Hi nice video, I have a question how to know that how many days it takes for all the solvent to evaporate leaving behind only a concentrated extract of essential oil?

6:42 This scene made me hungry for French cheese.

Give me the "Condenser" link please

I would like to know the heat setting😮

Where to buy crude oil?

Just inject it into my veinsssss!

How can I ensure no hexane is in it?
