It was stated that the action of heated sodium hydroxide upon ?, ? `-dichlorodiethyl ether produced a liquid boiling at 39 �C ( among other identified products ) . ( Major, 1935 ) However, in a subtly modified process Hibbert et al . reported the isolation of a product boiling at 34-35 �C, " divinyl ether ".
3.
This substance produced results placing it between diethyl ether and divinyl ether both in terms of toxicity and speed of induction and recovery, producing promising results similar to V . A . M . ( Grosskreutz, Davis 1956 ) Despite much simpler synthesis ( vinylization of ethanol with acetylene ) ethyl vinyl ether didn't enter widespread use in anasthetics, as superior halogenated ethers replaced it shortly after its first trials.
