If you don't have a license, you simply should not buy it, regardless of whether you have purchased H2SO4 before or not.
The company violates the law and can get in deep trouble for selling to the general public, but you as a buyer also violate the law.
If you really want to do some experiments with HNO3, buy a decent amount of H2SO4 (still available up to somewhere in 2021 and still allowed to
possess for 18 months after that date as far as I know). Then you buy some NaNO3 or KNO3 and distill the acid yourself (you already have a
distillation setup). I also work in that way. I occasionally make small quantities of HNO3 (25 to 50 ml or so and use that in small-scale experiments)
from other legal chemicals. It is somewhat inconvenient, but if you only work at a small scale as I do (mostly test tube scale, sometimes a few tens
of grams in certain syntheses), then you can live with the inconvenience. |
