|m-picrylpicryl chloride||molecular mass
m-Picrylpicryl chloride has also been called 3-chloro-2,2',4,4',6,6'-hexanitrobiphenyl, and PIPICl. It has the appearance of pale yellow crystals and was first developed by J.C. Dacons & M.J. Kamlet round abouts 1966. As for useful information, other than the fact it is explosive, I have no more.

m-Picrylpicryl chloride can be prepared by refluxing 75 mL of pyridine with 0.33 mole of 3-methoxy-2,2',4,4',6,6'-hexanitrobiphenyl suspended in 1.2 L of benzene for 1 hour at 100 °C in a round bottomed 2-L Florence flask. Dissolve the product of the refluxing into 400 mL of phosphorus oxychloride and warm for 1 hour at 100 °C. Dump the whole works into ice water to precipitate the crystals of m-picrylpicryl chloride, filter to collect the crystals, and wash them with water. Allow the crystals to dry, and purify them by recrystallizing from n-hexane. A yield of 89% is obtained. You will need a graduated cylinder for measuring liquids, and a thermometer to monitor the temperature.
