Ester Disposal
Ester Disposal
Hi,
Can anyone tell me how to dispose of Esters? We have conflicting information - one says down sink to sewer and another says soak with perlite or paper. Please help.
thanks,
carol58a.
Re: Ester Disposal
I always put them in the hydrocarbon waste bottle.I know purists will say that is not strickly correct however given their preparation it is better then the sink.
Re: Ester Disposal
Not the sink!
I always put it in an organic waste, but if it is only smal amount, you can absorb it on perlite

Re: Ester Disposal
Our chemistry teacher always requests the organic waste bottle and she takes care of the waste and returns the bottle.
Re: Ester Disposal
Thankyou all so much. We will use an organic waste bottle, as it was what we were thinking. We thought down the sink was wrong - would you believe that came from the DET website. It is nice to have our thoughts confirmed.
Thanks again for you help.

Re: Ester Disposal
Ethers are different chemicals to esters. Eg of an ester is nail polish removal. I thought ethers are ban from schools.

Re: Ester Disposal
OK got it right this time.
taken from Appendix E CSIS Disposal of Waste Chemicals page 19
23 Hydrocarbons, alcohols, ketomes, esters, Heteracyclics
Warning
Flammable, can be toxic by inhalation
Wear
Nitrile gloves, safety glasses and laboratory coat. Work in a well ventilated area.
CLean up and disposal
* For small liquid quantities (<50ml.)
Absorb onto paper towel and allow to evaporate in a fume cupbaord. Once the chemical has evaporated the paper towel should be disposed to garbage.
* For larger liquid quantities (>50ml.)
Absorb spill onto vermiculite, perlite or cat litter. Mix scoop into a container, seal and store until collection by licensed waste contractor.
* Solid, Sweep onto paper and place in garbage.
Containers of hydrocarbon, alcohol, ketone, esters, and heterocyclics should be stored safely until collection by a licensed waste contractor. almost the same as 20 Ethers.
