Examples (External sources, not reviewed)
| Production Cellulose from wood, cotton, hemp or other sources is dissolved in alkali and carbon disulfide to make a solution called viscose, which is then extruded through a slit into a bath of dilute sulfuric acid and sodium sulfate to reconvert the viscose into cellulose. | O processo de produção se dá a partir de fibras de celulose de madeira, algodão, cânhamo, ou de outras fontes dissolvidos em álcali dissulfureto de carbono e para fazer uma solução chamada viscose, que é depois extrudida através de uma frincha para um banho de ácido reconverter a viscose em celulose. |
| Chemically, cellophane, rayon and cellulose are polymers of glucose and contain the chemical elements carbon, hydrogen and oxygen. | Quimicamente, celofane, raiom e celulose são polímeros de glicose e contém os elementos químicos carbono, hidrogênio e oxigênio. |
| A similar process, using a hole (a spinneret) instead of a slit, is used to make a fibre called rayon. | A processo semelhante, usando um buraco (uma fieira) em vez de uma frincha, é usado para fazer a fibra chamada raiom. |
| Peanut shells are used in the manufacture of plastic, wallboard, abrasives, fuel, cellulose (used in rayon and paper) and mucilage (glue). | Eles também são usados para fazer celulose (rayon e utilizado em papel) e mucilagem (cola). |
