Preparation of cellulose diacetate by recycling processed film |
| abstract |
A one step process for preparing cellulose diacetates from processed film having cellulose triacetate as a base. The process involves use of an organic acid such as acetic acid and a solvolysis agent such as an alkanol or water. Hydrogen and a hydrogenation catalyst are optionally employed. The process allows for a simple way of recycling a material that presently is not recycled to any appreciable extent. |
