Title: Improvements in or relating to the preparation of vinyl ethers
IPC: C07C43/16
Filed: 1951-12-18
Abstract: Vinyl ethers which boil below 200 DEG  C. at normal pressure are prepared by reacting an alcohol whose vinyl ether boils at above 200 DEG  C. with acetylene at 130-230 DEG  C. in the presence of the alkali metal alkoxide of said alcohol, and thereafter feeding acetylene and the alcohol corresponding to the required ether to the resultant liquor maintained at a temperature of 130-230 DEG  C. If desired some of the alcohol corresponding to the higher boiling ether may also be added along with the alcohol corresponding to the lower boiling ether.  In the examples (a) cetostearyl alcohol is reacted with potassium hydroxide and acetylene is passed into the resultant mixture; the feed of acetylene is continued and sec.-butyl alcohol is also passed into the mixture; a mixture of sec.-butylvinylether and ceto stearyl vinyl ether is obtained; (b) the process is carried out as in (a) except that tert.-butyl alcohol is used instead of sec.-butyl alcohol giving the tert.-butyl vinyl ether; (c) a mixture of cetyl alcohol and potassium hydroxide is treated with acetylene; isoamyl alcohol, cetyl alcohol and potassium hydroxide are passed into the resulting mixture while the supply of acetylene is maintained and a mixture of isoamyl vinyl ether and cetyl vinyl ether is obtained.
