# Mixing solvents and other compounds - safety issues

I would like to know if it is safe to mix organic solvents together or organic solvents with some compounds listed below.

In a mixture with random ratios (greater than zero - all chemicals present) we have:

• Ethanol
• Methyl ethyl ketone (as denaturant for ethanol)
• Bitrex (aka Denatonium - as denaturant for ethanol)
• Isopropanol
• n-butanol (as denaturant for isopropanol)
• n-propanol (as denaturant for isopropanol)
• Ethyl acetate
• Acetic acid (in case that ethyl acetate hydrolyzes)
• Water (from ethanol and isopropanol)
• Acetone
• Methanol
• Naphtha (Hydrogenated)

In general, we have alcohols, ketones, denatonium, ester, organic acid, water, and a liquid hydrocarbon mixture (Naphtha).Ratios can be taken as equal for all chemicals except those used for denaturation.(I think ratios for denaturants wouldn't matter in case they would react.)

Could some of these chemicals react together and produce any unstable or hazardous compound?

What conditions should be avoided? (Light,heat,etc.)

Any reaction (slow) that could happen with atmospheric oxygen? (opening and closing a bottle containing all these chemicals)

I don't know too much about organic chemistry, just asking to be sure this is safe.I want to test something that possibly involves mixing all the above chemicals and I don't know if they could probably react together.

Note: Question unrelated to waste disposal. I'm experimenting with a DIY electronics cleaner.

For your list of waste disposal (as it seems to be) most of your products are alcohols or water so they can be mixed without issues. The ethyl acetate will react with water to create ethanol and acetic acid and acids may be an issue if you have great quantities. So I would suggest to react and neutralise with $\ce{NaOH}$ prior disposal. Same thing for acetic acid: you should neutralise prior disposal.
