soluble in water;
soluble in alcohol and About 100,000 kilograms (250,000 pounds) of the
ether n-butyl isomer, the most popular, is produced each year in
the United States. By far the most common use of the com-
pound (and the isomers) is as an industrial solvent, with
about 90 percent of total output going for this use.
