Basics

  • Cellulose is rather difficult to dissolve in most solvents
  • Dissilving cellulose is rather useful for the production of textiles (Like Rayon). as well as the production of bioplastics (Cellophane)
  • It is also useful for obtaining a high purity cellulose for various other chemistry and biology uses
  • Thus developing special solvents is a useful accomplishment

Solvents

  • Exerpt From The Cellulose Wikipedia Page:

Cellulose is soluble in Schweizer's reagent, cupriethylenediamine (CED), cadmiumethylenediamine (Cadoxen), N-methylmorpholine N-oxide, and lithium chloride / dimethylacetamide.[19] This is used in the production of regenerated celluloses (such as viscose and cellophane) from dissolving pulp. Cellulose is also soluble in many kinds of ionic liquids.[20]

Schweizer's Reagent

  • See Schweizer's Reagent
  • Possibly The Simplest To Make
  • Also safe (assuming you don't drink it or dump it in a river etc)

Viscose Method

  • Two Part Process (Exluding Pulp Processing (ie just the dissolution is two steps) ):
  1. Pulp is treated with an alkali solution
  2. Alkali-Pulp is treated with Carbon Disulfide
  • The carbon disulfide used is a rather nasty chemical
  • See Viscose Method for more info

Dimethylacetamide

  • Complex (and proboably quite expensive)
  • Quite Toxic
  • Not of too much intrest

N-methylmorpholine N-oxide

  • VERY complex and expensive
  • Possibly the most effective method commercially used (ie most pure product)
  • Not too much information outside of scholarly papers (more delving into these is nessisary)
  • See N-methylmorpholine N-oxide for more info
