pyroxylic spirit - Nature
Open Data Verified Data
colorless clear liquid, the vapor and air can form an explosive mixture, when burning to produce a blue flame. The critical temperature was 240.0 ℃; The critical pressure was 78. 5atm. With water, ethanol, ether, benzene, ketones and other organic solvents miscible. Its vapor and air to form an explosive mixture, fire, high heat caused by combustion explosion. A strong reaction with an oxidizing agent can occur. In case of high fever, the internal pressure of the container increases, and there is a risk of cracking and explosion. There is no flame when burning. Can accumulate static electricity, ignition its vapor.
