It was reported that washing XXX only with XXX solution will stop the decomposition of SO3H in cellulose (of course if you only use XXX, it won't cause this problem). The SO3H makes XXX decompose, and probably it increases the sensitivity of XXX.
I don't know what will happen if using Hhx2SO4 instead of HCl when making XXX, but it seems to be very difficult to produce DADP. I made a bottle of XXX (stored in water) without cleaning acid and nothing happened. Another time I made it without controlling temperature, and the mixture only splashes out XXX crystals. The dry XXX is extremely dangerous, you can test it by grinding or hitting when it's dry, but only test it in a very small amount (0.05g is enough)

XXX 和 DADP（忘改了） 都是物质名
