SUMMARY

The discussion centers on the synthesis and storage of nitrocellulose, specifically a 5-gram batch created from cotton balls. The user initially stored the nitrocellulose in a plastic Ziploc bag for two weeks without issues, but after combining two batches, they observed condensation and a chemical smell, leading to the dissolution of the substance in water. The user questioned whether this indicated decomposition or if other factors contributed to the observed changes. The thread was subsequently locked due to the topic's sensitivity regarding explosive materials.

I synthesized 5 grams of nitrocellulose from cotton balls. I stored it for a couple weeks with no problem. I feel as if I didn't neutralize it very well, but I did wash it with water very thouroughly and dried it. It was safe to touch and dried fine. I stored it in a plastic ziploc bag for two weeks and all was good. I made another 5 gram batch which washed out even more white and neutralized to the full extent. I added the batches together in the same bag for further use. After another two weeks I noticed the bag had a foggy condensation look, even though I know the substance was completely dry. My first instinct was to open the bag and leave it to evaporate. After about two weeks, I examined it again and I noticed everything was mushy with a strong chemical smell. I dumped it into water to wash it with sodium bicarbonate. Before I could add the baking soda, the nitrocellulose completely dissolved. Did I discover the decomposition of nitrocellulose? Or is there another factor in play here?
