- Abstract
The cheminal degradation of propyn-2-yl N phenylcarbamate on various homionic clays (Bentonite Prolabo. Montmorillonite K10; Cu2 , Ag , Zn2 , Fe3 ) was investigated at room temperature. Only copper and silver were active. The kinetics of the degradation was generally slower than that previously described for chlorbufam. Cyclization of oxazolidinone and carbamate function hydrolysis were observed simultaneously. The selectivity of the conversion was influenced by the impregnation technique, clay type and exchange cation. Isocyanate was involved as an intermediate in the carbamate function hydrolysis.
