Schweizer's Reagent
Contents
Basics
- A Chemical With The Name and Formula: Tetraamminediaquacopper Dihydroxide, [Cu(NH3)4(H2O)2](OH)2
- A solvent that dissolves cellulose
- Has the advantages of being simple to make, as well as relitively non-toxic (outside of ingestion or reckless disposal procedures)
Used For
- Production of Semi-Syntetic Fibers From Reformed Cellulose
- Production of Bioplastics From Reformed Cellulose
Industry Standards

Existing Open Source Designs
Nile Red's Work
Thoisoi2 - Chemical Experiments!'s Work
Minimum Viable Product
- Able to be made from easily obtainable materials (ie cheap, or diy)
- Usable like the leading industry formulation (ie it dissolves the same amount per litre etc)
Basic Design
Chemical Preparation
- For Producing 1 Liter Of Soluion:
- 20g Copper (II) Hydroxide
- 1L Ammonia Aqueous Solution
Procedures (Assuming Manual Use)
- Gather All Materials Specified in the BOM
- Prepare the solution according to the informaion listed above
- Have the solution in a container with means for stirring it (Such as a beaker/vat with magnetic stirring)
- Slowly Add A Source of Clean Cellulose (Such as cotton)
- Once the Solution is Saturated Stop Adding Cellulose, and Continue to Stir for ~1-10 Minutes
- Turn of Stirring
- To Bring the Cellulose out of Solution, Decant (Either by pouring, or by using something along the lines of a srynge) into a Mildly Acidic Solution (Acid choice is mainly a question of what acids you have, and what reaction you prefer for recycling the solution
- Stir Once the Above Step is Done
- Once The Strands Are a White-Translucent Color, and They Have Lost Their Blue Hue, Wash Them With Distilled Water Until The Desired Cleaness/Purity is Reached
