Hi all dear walking lights )

what do you do with your chem waste? espesialy xylen dcm and the more badass stuff, if you dont have fansy distilation setup and after each extraction you stuck with impure chems?

swim want to go ecologocal way and dont pour it in the ground and yes of course distalation is the eco way but not for the small kichen chemist.

btw swim one's do the mistake of puring xylen in the sawarage and hes neighbers smell it from there bathroom and he has to make up stuff, really not pleasent expirience.
he gusses that with p.eter its ok but for all the nasty chems he want to find a better way for disposal.

See if in your town you have a chemical disposing place.

Otherwise, solvents can be left to evaporate somewhere safe, base can be neutralized with an acid and then discarded down the drain (some people even use bases to unclog drains directly)

swim also pour base to drain, he dosnt think he have disposing place and if he has
dont it be susspicous that he want there services? (from looking at swim you can tell imidiatly for what the chem was used)

it's 2018. nobody swims anymore.
if one can't distill, one uses molecular sieves.

the best thing one can do is invest in equipment, if one is serious about [sustainable] chemistry.

so the point is that the molecular sieves will absorb the waste and the solvent will be ok to use/to find how to deal with?
and the size of the sieves will depend on the solvent used right?
please explain a bit more about using sieves

to invest in distiller is on TOP PRIORITY! but monetary issue sadly makes it not relevant for now, its wet dream that will have to wait for now...

mol. sieves are used to dry organic solvents, wicking up residual aqueous solutions.

now that I think about it, you could wash your organic solvents with 5% sodium carbonate, separate, and run through molecular sieves, or pour into a contaner with magnesium/sodium/calcium sulfate salts, to dry them.
this will only address the aqueous contaminants. to separate fats, you'd need to cool the solvent in the freezer, then filter, and pour through activated carbon.

this is a pretty decent topic. I'll search for any e-books I may have, and attach them.

one could use a simple water bath distillation for low-boiling solvents: a pan or large dish holding hot water, with a large glass container containing the dirty solvent, and a smaller glass container in the middle to collect. a curved glass lid would be placed on top, to drip condensed solvent into the collection container.

then dry the solvent with (dried) epsom salt*.

*epsom salt is magnesium sulfate heptahydrate. it can be dried by microwaving for 5-10 mins, or baked @ 300-400F for 1-3 hrs.

For a lot of processes and non-polar solvents (xylene, limonene, toluene, naphtha), you can also reuse them pretty much indefinitely

Wash it out repeatedly with both acidified and basic aqueous solutions, you can even filter it if you think there are tiny suspended particulates. Then reuse.
