The Presence of 3, 4‐dichloroaniline in Rice Grain Hydrolysates

Summary. Identification of 3, 4‐dichloroaniline in a hydrolysate of rice grain obtained from experimental plots treated with N‐(3, 4‐dichlorophenyl) propionamide (propanil) and in rice grain purchased on the consumer's market is reported. Rice grain harvested before the introduction of pesticides that contain 3, 4‐dichloroaniline but treated with isopropyl N‐(3‐chlorophenyl)carbamate (chlorpropham) yielded rice cereal from which, after caustic hydrolysis of the rice grain, 3‐chloroaniline was isolated. The presence of chloroaniline or chloroaniline‐containing compounds raises the question as to the source of the contaminants.
