Mercury-Sensitized Photochemical Action on a Mixture of Isobutane and Isobutene

Mercury-Sensitized Photochemical Action on a Mixture of Isobutane and Isobutene

Date: June 1939
Creator: Gary, Felice
Description: This study investigated mercury-sensitized photochemical action on a mixture of isobutane and isobutene. Flow runs of isobutane-isobutene 3.2.1 mercury-saturated gases illuminated with unfiltered radiation of mercury vapor lamp gave no detectable change to hydrocarbons heavier than C4 at reaction tempratures of 27C. and 99C.
