摘要：
According to one aspect of the present invention there is provided a substantially high purity D-(−)-N,N-diethyl-2-(α-naphthoxy)propionamide and a process for the manufacture of substantially higher purity D-(−)-N,N-diethyl-2-(α-naphthoxy)propionamide having chemical purity near about or above 95%, and chiral purity near about or more than 97%. According to another aspect of the invention is to provide an agrochemical compositions containing highly pure optically active D-(−)-N,N-diethyl-2-(α-naphthoxy)propionamide.
