Document Type and Number:
WIPO Patent Application WO2003084908
Kind Code:
A3
Abstract:
Epoxyalkanes are subjected to at least one of the following washing operations: (1) washing with aqueous inorganic base, and then with aqueous borohydride, or vice versa; or (2) washing with an aqueous solution of both inorganic base and borohydride. Undesirable odor is reduced or eliminated from alkanediol(s), if produced from the treated epoxyalkane(s) by hydrolysis. Use of such washing procedures in the production of alkanediols is also described.
