Stabilized aquous diazo solutions |
| abstract |
A stabilized aqueous solution of a diazo compound hasnthe formula:n nwhere X 1 is selected from nitro and chloro, X 2 is selectednfrom nitro, chloro and nothing, and Y is an acid-derivednanion. The solution has a pH of about 1.5 or below and andiazo concentration of about 2 wt% or less. The solution isnuseful as an extractant/developer for petroleum fuelnmarkers. |
