65 °C decomposes
This compound has the appearance of canary yellow needles. I have very little information about this compound other than it is sensitive to light, it may explode on standing, it is insensitive to friction or impact, but will explode on contact with flame, concentrated sulfuric acid, and nitric acid. This explosive was first prepared around 1914.
Prepare a mixture of 1 g of benzaldehyde phenylhydrazone suspended in 6 mL of benzene in a small Erlenmeyer flask. You can make any volume desired, but keep the same 1 g per 6 mL ratio, keep in mind the danger increases in making more. While constantly shaking the mixture, bubble oxygen gas through it for 6 hours. It may seem bothersome to shake this stuff all the time and I doubt you have an automatic shaker, so you might be able to get away with shaking it for a minute every 10 to 15 minutes. Inserting the end of some rubber tubing from your oxygen generator may not yield good results, it is far better to use a bubbler similar to a fish tank aerator. A bubbler may be somewhat costly, but better in the long run, you can use a fish tank aerator but it may dissolve in the benzene (this has happened to me, the aerators are just sand pressed together). Another potential problem is that there will not be enough room for a fish tank aerator , with such a low volume of solution since they are cylindrical, whereas bubblers can be flat. After the oxygen addition, add cold petroleum ether to crystallize the product out of solution. Pour the crystals over a vacuum filter to collect and dry them faster. The yield is about 73%. Keep the product away from light and dispose immediately as it may detonate on standing. You will need a graduated cylinder to measure liquids.
