Web30 de nov. de 2006 · Most likely, the explosion was caused by peroxide contaminants in the solvents that had concentrated to the point of being unstable. Both tetrahydrofuran (THF) and diethyl ether were used in the reaction, and both of these solvents form peroxides over time. In this case, the THF used did not contain a stabilizer (such as BHT) to slow the … WebThese chemicals may explode when relatively small quantities of peroxides are formed. These items normally have an inhibitor (scavenger) added to the substance by the manufacturer in order to prevent peroxides from forming. This inhibitor can be removed if it interferes with the use of the chemical or the chemical is redistilled in the lab.
