Hydrogen Peroxide H2O2 -done

Put solution into ice bath, so that temperature is below 5°C. 

Add 21 ml of citric acid slowly keep temperature below 30°C. 

Check with PH paper. There should be no acid. The acid doesn t allow long term storage of an explosive. 

The preparation for this is available but it is quite useless. It explodes at 86C. Takes 

It can be used also as a primer cord although it is used in a detonator.

Tests have been done further on the separation of a Cu-Pb mixed concentration of ethyl xanthate flotation of copper-lead-iron sulphide ore by E- control modifying with H2O2. Test results are presented in Table 10.3. It indicates the possibility of selective flotation separations of copper-lead flotation concentration by control. The feed of copper-lead mixed concentrated assayed Cu 6.53% and Pb 62.38%. Using hydrogen peroxide as a potential modifier, a copper concentration with 24.19% Cu and recovery with 89% can be obtained after separation. 

Huang et al. [59] evaluated some common excipients for residual levels of hydrogen peroxide. They found levels of H2O2 in the range 0-244 ppm, but perhaps of more concern, they showed quite pronounced differences between different batches of the same vendor and between different vendors of the same excipient. For example, although there is some variability of residual peroxide levels in PEG 400 (polyethylene glycol) from vendor B (5-16 ppm), the differences were small, in contrast with those seen from vendor C (2-59 ppm). Similarly, the differences in residual peroxide in the binder PVP (polyvinyl pyroli-done) from two different vendors were quite marked (73 vs 244 ppm). Formulations optimised for excipients from specific sources could well be sub-optimal if the... 

Catalytic H2O2 Oxidations. The reactions were carried out in 10-mL tubes equipped with serum cap and a stirring bar. The catalyst, hydrogen peroxide, and substrate were dissolved in of CH3CN. Trimethylacetonitrile was added to the reaction as an internal standard. All reactions were done under argon, each was purged by three freeze-thaw cycles and GC analysis was performed on aliquots withdrawn directly from the reaction mixture. Typically, alkene (1 mmol) was added...
