What does SADT stand for in the context of organic peroxides?

• A. Self-Accelerating Decomposition Temperature
• B. Safe Auto Decomposition Test
• C. Self-Acting Decomposition Temperature
• D. Standard Auto Decomposition Thermodynamics

Answer: (A)

In organic peroxides, SADT is the temperature at which decomposition becomes self-accelerating, meaning the heat generated by the reaction increases the rate of decomposition and can lead to a runaway situation. This single temperature value is used to gauge stability and set safe storage and handling limits, helping determine maximum storage temperatures and required safety measures. The term you’re looking for is Self-Accelerating Decomposition Temperature because it specifically describes this risk of runaway decomposition. The other phrases aren’t standard terminology in this context—they don’t correctly capture the idea of a temperature at which self-accelerating decomposition begins.
