Disposal considerations

Industry - Possibility of recovery/recycling: The recycling of the substance is possible. The contaminated

substance can be redestilled before reuse.

Industry - Possibility of neutralisation: Neutralization is possible. Adding slight acid (pH 4) the

substance can be broken down quickly into 2-butene-1,4-diol

and acetone.

Industry - Possibility of destruction: controlled discharge: Not applicable

Industry - Possibility of destruction - incineration: Can be incinerated in a suitable incineration unit pursuant

to the local statutes.

Industry - Possibility of destruction - water purification: An acid-catalyzed hydrolysis is to be expected since ketals

like dimethyldioxepine are readily cleaved by acid to form

diols and ketones but are stable to bases. In the case of 2-

butene-1,4-diol and acetone.
