- I did this one other time using actual wood pulp which resulted in a perfectly white and pure cellulose. Using weeds is not recommended and I only used weeds for the novelty of it.
Materials Required:
-Sodium hydroxide
-Ortho-Xylene
-Ethanol
Key Hazards: Sodium hydroxide is caustic, ortho-xylene is toxic, ethanol is flammable

The fibers you made were all mushy because they were mechanically processed (blenderized) into tiny bits, which cuts all the fibers. The leaves etc also have very short fibers to begin with so you didn't have much to work with. Plant stems will tend to have longer fibers, at least on the outside (the inside pith will have short, weak fibers). You may also have cooked it a little too long, although in kraft pulping (sodium hydroxide with sodium sulfide) delignification doesn't start at any practical rate until over 300 F. 120 minutes even at 212 F would not normally do much to a heavily lignified fiber - although the leaves should be fairly low in lignin as well.
As far as making paper, normally the pulp is suspended in an excess of water and the slurry is passed through a wire or forming fabric. For short fibers like that, a window screen would probably be too coarse. You could try using a piece of filter paper and a vacuum funnel to make a small handsheet.

Hey...do you work in kraft pulp mill....I am a biotechnology student we have a project in our college on paper production so I have many doubts on that would you pleaseee help me...!
Please reply!
What about nitrating this cellulose powder? It would be interesting if it burns faster or slower than nitrated normal paper or cotton.
But I would recomment purifying it beforehand by dissolving it in Schweizer's reagent (tetraammincopper hydroxide) and precipitating it out by addition of dill. sulfuric acid to the ammincopper cellulose solution.
Also the first filtrate of the green slurry might be interesting for further experiments with chlorophyll (its red fluorescence for example), which could be extracted with aceton if the aqueous suspension is saturated with table salt beforehand. Denat. ethanol can be used, too, but then you should use potash to salt out the alcoholic chlorophyll solution.
good stuff! Thanks
Amino acids enzimatis please for next
Hi I am finding for how to extract cellulouse and pectin from the flower and plant. I'm from Korea and high school student. Watching this video, did you had expermient more about this? If you don't mind, can you answer my following questions?
Is there some improved idea of extracting cellulouse?
I want to make bioplastic by extracting cellulouse and pectin, and I've heard that we can't seperate pectin and cellulouse in the plant and flower. I'm not sure, so if it's possible to seperate pectin and cellulouse frome plant or flower, can you tell me the way extracting them respectively?
I'll be waiting for your answer!
Could potassium hydroxide be used in the initial step? I'd like to do an ethanol fermentation of cellulose and potassium is better for yeast health than sodium
Awesome for me , because I tried some kiddish experiments with cactus flash and failed the you shared in this video. Can you help me in that?
I have a question about CNF(cellulose nano fiber)
In Japan, there r powder ver. of CNF that can be mixed with food like Bread, mochi or any other food to add some Squeezy nice texture for food AND it can expend the expiry date of most of food.
Do you think those CNF contained food has high or some risk of cancer or anything for long-term consumption?
It may not be ur speciality but I just wanted to ask abt your opinion 😊
I see this CNF been used for tire, pancakes, clothes, paper, etc.
I see future companies making $$$$ money with CNFs product in the future (cuz it sounds too good like scam sounding level 😅) that is why I wanted to know ur personal opinion 😊😊
Thank u so much for those entertaining content!!!
I'm not a science boy, just a artist but I can guess ur process and I enjoy it 😊
what if you dont have ortho xylene? and just have sodium hydroxide and sodium hypochlorite
It is really nice video. If already fallen leaves are used, hexane employed in place of xylene, it would be a very great eco-friendly upcycling of agricultural residue. Do you think it works with waste paper or cardbox ?
I agree 100% I actually came up with this idea by accident. My initial idea was to extract the different chemical components in grapes, but the only thing I could isolate in significant quantity/purity was cellulose so I scrapped that project and did this one.
On that note, even though this video isn't very popular, I do fully intend to follow it up with a few more similar experiments.. It would certainty work with waste paper btw.
@@integral_chemistry Hello. Can this cellulose extraction method be used for tiger nuts?
You could attract some interesting followers with a spearmint extraction of carvone.
Hello I’m a high school student in Jeju, Korea. I watched your video about cellulose extraction while making a school science project using cellulose. And then I have some questions. Could you answer some of my question?
-Can I use dried resources for cellulose extraction?
-Can I know exactly how to do the experiment?
-It is mandatory to use bleach in the experiment?
If you answer these questions, it will be of great help to us. With the help of a translator, please refer to any expressions th
Hello, I am a highschool student here in the Philippines. We plan on following your process on extracting the cellulose but there is no available 20% sodium hydroxide solution. Would it be possible for us to use sodium hydroxide solution only?
Do you know the concentration? It needs to be quite strong. Alternatively you can actually remove lignin with organic solvents like ethylene glycol. I'm doing a video on that now but I doubt it will be finished in time for your project
Sir, wonderful and informative video, thanks a lot. I'm a PhD scholar, can you please help me with the extraction of nanocellulose
Thank you so very much! I would love to help but I have to say that I am by no means an expert when it comes to cellulose specifically, or polymers in general. I'm working on researching more in this area as it seems there is more interest in this topic than I expected but as of now I am still very much in the research phase. Based on what I know now though it seems like nanocellulose can be obtained by acid hydrolysis or ultrasonication (or both) of raw cellulose fibers.. Keep an eye out for a video on this topic as I'm working on it but as of now I don't have much concrete.
thanks a lot, for the reply sir, I'm working on nanocellulose extraction right now, I hope I could succed.
It's interesting to see the whole process, I found it's the fundamental science 🧪, everything was good till the last step, yes the final process can be added with a glue which can stick the cellulose intact the polymerization activity for forming a sheet. Paper sheet formation is preety easy bring all your stuffs under a cylindrical roller and just press them. It will work like a hydrollic.
For digestion you may take help of cellulose degrading bacteria available in the market that can work more efficiently & fasten the whole job.
Keep shining and following your heart.❤
Pls make it on cow dung cellulose extraction
Please tell about the publication about this processes
It would be interesting to see the result if you dissolved the material for cleaning in Schweizer's reagent instead of Ortho-Xylene.
I made a search on the fly making me think thar your paper making stage is way to dry.

Yeah I recently redid this project as true removal and isolation of lignin ended up being a much harder process than I realized back then.. I definitely did an okay job here but was far short of genuinely pure cellulose.
Interestingly enough I was planning to do the Schweizer's reagent dissolution today 😅

You would probably have got a really cool aged look paper if you'd had the crafting part in place in the video above.
The channel Laboratory of Liptakov has an easy and unexpected way to make the reagent that appears to work.
Nitrate it!!
