carbonate or calcium carbonate, clay cat litter (bentonite), and sand. The use of plastic
scoop, scoop into a plastic bucket. In the hood, smoke, slowly add the mixture to a large firm
amount of water and allow to stand until the reaction is not complete. Filter the solution to drain.
The solid residue can be considered as a normal failure 7
Waste Disposal
Wear gloves of butyl rubber, laboratory coats and eye protection. Work in the hood smoke.
Containers chloromethyl methyl ether, which were open and supplies are stored {}, can
contain peroxides. Especially if they have screw caps, they must be handled with great
care {caution}. Where the container can be opened safely, check for peroxides as follows:
smoke hood, add 1 mL of ether to a solution of 100 mg potassium iodide in 1 ml
Glacial acetic acid. Pale yellow color indicates a low sulphuric acid concentration, and a bright yellow
or brown, high concentration of peroxides in the sample 8, if peroxides are present,
they can be removed by passing air through a column of basic alumina.
Packet stream for disposal by burning.
