What is 1,4-Bis(vinyloxy)-butane?
The Uses of 1,4-Bis(vinyloxy)-butane
1,4-Bis(vinyloxy)-butane, which also serves as an intermediate in manufacturing higher perfume chemicals, has found some use in perfume compositions, mainly for its diffusive power and “lift” in soap fragrances, detergent perfumes, etc. It seems most conceivable that certain Vinyl ethers are the intermediate steps made by Mother Nature in the manufacture (biosynthesis) of some very interesting and important odorous chemicals, including “Rose oxide”. Many Pyran derivatives are made by means of Vinylether synthesis.
Production Methods
1,4-Bis(vinyloxy)-butane was produced from Tetramethylene glycol and Acetylene, using pressure and a catalyst.
Flammability and Explosibility
Flammable
Solubility in water
Insoluble in water, soluble in alcohol, miscible with oils.
