Product name secondary butyl alcohol
Synonyms 2-butanol
GOST no data
CAS 78-92-2

2-Butyl alcohol is a clear liquid with a strong alcoholic odor. It is miscible with a number of organic solvents. Isobutanol is soluble in water and it forms azeotropic solution with it (32.0% H2O by mass, bp 88.5°C). sec-Butyl alcohol is a typical aliphatic alcohol;


sec-Butanol is manufactured by interaction of 70-85% sulfuric acid with butenes from C4 fraction of thermal or catalytic naphtha cracking. Then sec-butyl sulfuric acid is hydrolyzed to give sec-butanol. C4is used being previously rectified from isobutene and butadiene.
