Cellulose
What is and what are the qualities of
cellulose?
Cellulose is a polymer with a formula (C6H10O5) n, which is glucose-derived
and insoluble in water. Cellulose has physical properties that are very
significant and they are caused by two factors: the molecular weight is very
high and the chains are not branched. The form of bond from which it is
produced is one of the most important chemical variables that cellulose has,
namely: 1,4-ß-glucosidic. Because of this bond, which involves the breakdown
of unique enzymes but which the human body does not have, it can not be
assimilated by man. While certain animals, like cows and sheep but even
others, which do not have the enzymes to sever this bond, carry out
subsequent chewing of grass or leaves after leaving it in the stomach for a
period of time, as the microorganisms present in the stomach supply the
enzymes over that period of time, this helps them to assimilate cellulose. It is
also present in most plants, and it contains around 50 percent cotton fibers or
pure cellulose, specifically because it is stored in plants and therefore also in
wood. In addition, to determine its degree of polymerization, its viscosity is
taken into consideration.
How is the cellulose structure structured?
The arrangement of cellulose consists of chains arranged parallel to each other
and hydrogen bonds attached to each other. In this way, it is possible to form
fibrils, very long chains, difficult to break, even very orderly, they can actually
even form crystalline structures. This section is hydrophobic, but to maintain
hydrophilicity, cellulose must undergo a treatment called mercerization.
Cellulose is hydrolyzed under some conditions into cellulose disaccharide,
which is subsequently hydrolyzed into glucose.

The extraction of cellulose is primarily from wood, but also from straw and
many other raw materials from vegetables. Many methods of extraction exist.
The wood toasting procedure, in which lignin is dissolved in lignosulfonic acid,
is one of these. In addition, at the same time, hemicellulose is also dissolved,
thereby obtaining pure cellulose. The other may be a form that uses
magnesium sulfite or calcium bisulfite. Leaching happens in a tower filled with
limestone or dolomite in this process. The tower is sprayed with water and the
flow of sulfur dioxide is triggered at the bottom. The threshold joins the water
and to create a bisulfite calcium, the solution erodes the limestone. Reducing
the wood to pulp is one of the most widely employed processes, and then
curing it with an effective solvent that can remove coating compounds such as
lignin and hemicellulose from the wood. The final solvent discharged is dark
and the reagent from it is retrieved. The process of chlor-alkali is different from
other approaches because in two towers, the cellulose is constantly removed.
On top of both buildings, the compressed wood is filled and sprayed with soda
water in the first floor, and chlorine treated in the second tower. In the kettle,
the cellulose is first inserted, then into the diffuser and eventually into the
