IDENTIFICATION OF ETHYLENE AS A VOLATILE PRODUCT OF THE FUNGUS PENICILLIUM DIGITATUM

Abstract
The collection and identification of small concns. of ethylene from gas streams has been greatly simplified. Ethylene is absorbed in a soln. of 5% HgO in 2 [image] HClO4 and subsequently released by addition of 2 [image] HC1. The ethylene so collected is reacted with bromine and the dibromide is identified in turn as N,N[image]-diphenylethylene-diamine and N,N[image]-diphenyl-N,N[image]-dianilinothioformylethylenediamine. With this technic, ethylene was identified as a volatile product of the common green mold of citrus fruits, P. digitatum.
