Thank you for the video. Because of COVID we are only going in labs for 3 hrs, 4 times the entire semester. So we have to be very prepared before attending. Your video helped clear up the procedure immensely.

What is being extracted? I thought the sodium bicarbonate was being used to do the extraction from the methylene chloride...why does the methylene chloride need to be evaporated at the end?
Hello!! It's the first video I have watched from you so far, so I don't really know all the videos you have made. My suggestions are: precipitation of proteins, enzyme kinetics, particle Barr or blood groups! Your videos are very helpful!! I am really grateful!!! Keep up the good work and please help us to become good scientists!!!
Thank you very much for the video, I have a question, what filter paper do you use to filter sodium sulfate?????, if I need it to not retain oils and fats, the cellulose one would not work for me, what would you advise me?
@@muhammadrizkyfauzi5003 filtration, have the damped solid, put it under the red IR lamp. Did you check out my other video on suction filtration? it is there, have a look!
hey man! Love the video and the way you present it. I have a problem though... I'm doing this liquid liquid extraction of a carboxy benzo crown ether out of a ethanol-water solution after a reflux. The extraction is done with chloroform. The problem is, normally the carboxy benzo compound should be in the chloroform phase after extraction and evaporating the chloroform doesn't allow my crystals to form. Protocol used is this one: ''Cation Binding Properties of Crown Ether-Modified Polyet hylenimines'' on page 856. Any suggestions on how to get my crystals? This is for my thesis paper in University and time is ticking! Thanks so much
I have definitely lost compounds due to not making sure that the stopcock on my sep funnel was closed. I think everyone who does chemistry had done that st least once.
Hi, thanks for this video. I love it, quite clear and didactic. I am an assistant professor at the Institute of Chemistry - UNESP (Brazil) and I'm intending to use it in my remote practical organic chemistry course. As there is this watermark saying that its usage is subjected to permission, I'd like to know how to get this permission. Thanks
Hi Cintia, thank you for your interest, do you wish to provide a transcript in Portuguese while students listen in english? Do you students comprehend this video if they are being directed here? Stay well
@@chemfunman Hi! My students do not comprehend English enough to follow this video. I took a look at the automatic transcription and it is bizarre! So, I definitely wish to provide a transcript in Portuguese since the automatic one is awful. If it is ok for you I will work on it up the end of this week. Cheers
Oh tnx u sooooo much Yesterday i watched this 2hours before my lab xm,which i totally forgot, i Done my extraction experiment well, thank u so much but better if u teach how to recognize layers correctly,, using a ☺☺☺☺☺☺
hi..i am working on bioremediation. My bacteria has degraded a xenobiotic compound and i need to extract the degraded unknown compounds. In order to extract the unknown degraded metabolites from the broth, how do i choose the appropriate solvent for extraction?
+Prenumerera Mig fattar du? FATTARU??BACKARÅÅ Yes please give it a try! maybe you can look into this for better instructions. th-cam.com/video/LAkoutItjA4/w-d-xo.html on how to grind solid sample
unlikely, this extraction is good for solution. However, we know that Westphal et al. applies this exact same liq-liq extraction using phenol-hot water to extract endotoxins from bacteria culture.
Sir i have a question, When can we say that the lower surface is Organic layer? because the Water Density is higher than organic solvent. Because some reference said that Organic layer is the upper part. Thank you
use density. denser layer will be at the bottom. most organic solvents are less dense than water. a few, e.g. dichloromethane, trichloromethane are denser. so be clear!
really helped in my preparation for synthesis and extraction of 3-methylbutylacetate. I managed to attain full marks; no trace of any H2O on the IR spectrum. So its me who should be doing the thanking.
I find you tube an excellent resource when preparing for chemistry undergraduate practicals. One is able to obtain a feel for the techniques when they author explains in detail their actions and techniques. In my limited experience as a chemist I've found that little adjustments to the way procedures are carried out cumulatively make a big difference. Have you done a flash column chromatography one?and nitrophenylate ester hydrolysis?
Hi Fun, I'm doing research on extracting peptides from fish fillet for antimicrobial study, one of the procedure require me to do acidic extraction,which I need to remove acid from the organic solvent,can I use this method? What's your opinion?
Sounds ok to me, give it a try. Acid remove the amines in the fish. ensure that the temperature is not too high, if not it might cleave the peptide bonds.
+Genar Gundan This is an extraction protocol, we can grind the dry product using mortar and pestle, and use an organic solvent to dissolve the extract, after which, conduct the extraction procedures as shown in the video above.
When I try, it allways clump. Even when snowstorm effect happens, some parte of magnesium sulfate clump. Why? Is it normal or it does means that drying wasn't efective? Thanks if someboddy help me
Hey so I have an unknown compound. I want to do an acid base extraction on it. I think the compound is basic because of the solubility tests I did. Do I use HCl instead of NaHCO3 when adding to separatory funnel? thank you
+Samuel Lee if the organic compound you wish to extract is basic, first, add HCl to form a salt, so it goes into the aqueous phase. we get rid of the organic phase to eliminate organic impurities/ side-products. then, take the aqueous phase and add NaHCO3 to convert your desired compound back in to the neutral form (no charge) so that it goes into the organic phase, then collect the organic phase (so your aqueous impurities remains in the aq phase) --> rotovap solvent and TADA! see th-cam.com/video/HSZJcv8fg5c/w-d-xo.html
+FunMan Fung hey thanks so much for answering! Is it possible for me to use dimethyl chloride as the first step? Also instead rotovap is there another way to evaporate?
@@mantiger11 this is late, but you could vacuum distill the solvent if you don't have a rotovap or with low boiling solvents you could also just use atmospheric distillation
CaptainBaseball hi, we would only make it if this is pertinent to our pedagogical aim. :) By the way, why do you need ricin for? It is very toxic to humans! almost untraceable poision.

I have a question since your clearly a professor. what would you recommend for safety precaution's for various alkane nitriles such as acetonitrile etc. I know of course a good fume hood but with a good fume hood would doing reactions with such alkane nitriles be enough to prevent the worse case scenario (cyanide poisoning) What else would you recommend for safety. Any tips or what you would do would be great!
Danny Esliger Hi Danny, I am extremely regretful I just saw your reply, I hope this will still serve you good.The list is quite long (safety precaution for the chemicals aforementioned). What we normally do is to find the MSDS from the internet (many chemicals companies offer updated details) and sieve out those safety information that are pertinent to your students/ projects/ experiments. cyanide poisoning would be avoided as this is a controlled item. : safety data sheet :
The organic layer for this video is Dichloromethane (specific gravity = 1.3266 g/cm3) vs water (1.00g/cm3) so the organic layer is denser and stay at the bottom. In other extraction, using solvents such as diethyl ether (0.7314g/cm3), the organic would be at the top. We should always check the density before doing extractions to prevent losses.

How to extract or ferment dry product to get the oil?

When I try, it allways clump. Even when snowstorm effect happens, some parte of magnesium sulfate clump. Why? Is it normal or it does means that drying wasn't efective? Thanks if someboddy help me
If they clumped together, this is an irreversible process. no matter how much more you are going to add, these remain as clumps.
So does that mean it went wrong? Thanks for the atention!
Or if snowstorm effect hapens It does means that It is already done, even if I add more?
exactly! snowstorm means OK, no need to add further, proceed to filtration
Thanks very much!
