Rats were exposed for 4 hrs to 2-butene at a
nominal concentration of 10,000 ppm ( 22,948 mg/m3). No clinical signs
were seen and normal growth occurred over the 14d observation period. No
abnormalities were observed at gross necropsy. Only one concentration
was tested. This concentration was at the explosive limit and therefore
higher concentrations could not be tested.
