Abstract
Anhydrous normally-liquid ethers are prepared from "wet" ethers by adding sufficient silicon tetrachloride to react with the water present. If the ether is used for preparing Grignard reagents, any precipitate which settles out should be filtered off. Excess silicon tetrachloride is permissible if the Grignard compound is to be used for preparing alkyl, aryl, or aralkyl silicon halides, e.g. as intermediates for silicone resins. Examples describe the reaction of silicon tetrachloride with wet ether, and the use of the ether in the preparation of ethyl magnesium bromide when the precipitate had been separated, and also when the precipitate was not removed, but did not settle. A further example describes a failure to prepare ethyl magnesium bromide when ether containing a precipitate which settled was used.
