Hello, This video is so great. Thank you so much. I have 2 questions. How about hemicellulose?? And how do you know lignin dissolve and NaOH doesn't react with cellulose??

[@industrialadhesive6357]

Thank you I really appreciate it! There is most definitely hemicellulose being extracted by the alkaline solution along side with the lignin. Lignin is shown to be soluble in alkaline solutions. I don’t believe NaOH reacts with cellulose chemically, although I know at low temperatures NaOH in a aqueous solution can cause cellulose fibres to swell

are the bleaching steps (sodium hypochlorite & then hydrogen peroxide) necessary for the fiber extraction or are they just for getting it to come out white? And would this (either with or without the bleaching steps) result in a fiber appropriate for spinning into yarn, or would that take extra steps?

[@industrialadhesive6357]

I found the finer to be quite weak just due to the length of it, there are definitely steps you could to to spin it though, it’s better for making Kraft paper though. The bleaching was just so it would come out white it is not nessicary

[@dogodogo5891]

is peroxide necessary? i would like to make some delignified wood in whitest possible without it

It’s not impossible. You can use NaOCl but it will be fairly yellowish. Hydrogen peroxide is recommended

Yes you can. You may have to do additional lignan extractions but it should still work. You will have to add the fiber in an organic solvent and raise the pH and react the cellulose with mono chloroacetic acid

Your saying in the video that the NaOH destroys the lignin. Is it really destroyed or is it just being dissolved by the NaOH? Could the lignin be extracted from the water/NaOH?

[@industrialadhesive6357]

That was a poor choice of words on my part. What I meant is it dissolves the lignin. It can be precipitated out when the pH is lowered

I heated it for 4 hours at 90°C. But this all depends on the wood you are using. I used black spruce i think. But if you are working with hardwoods. This could take alot longer. So 4 hours is not a definite time but for me it was long enough to destroy most of the lignin.

It could be down to the wood your using. Hardwood tends to be more difficult to extract the lignan from compared to a softwood like spruce or pine. You can potentially use a higher molarity mixture of NaOH. Or maybe let it sit in the solution for longer. But with me i just pulled the wood apart by hand then blended until it became a pulp

To a degree. The oxidization may destroy some lignan but i am not entirely sure. However using a alkali hydroxide is preferred.

I mean it should work either way. Typically you want to add the solute to the solvent and not the other way around. This is especially the case for strong bases like NaOH where if you add it the other way it can cause the water to boil and spit

One more question. Does the wood fall apart or easily pulled apart?
