Napropamide
THE TITLE COMPOUND [SYSTEMATIC NAME: N,N-diethyl-2-(naphthalen-1-yl-oxy)propanamide], C17H21NO2, crystallizes with two independent mol-ecules in the asymmetric unit in which the dihedral angles between the naphthalene ring systems and the amide groups are 88.1 (9) and 88.7 (3)°. Four C-H⋯O hydrogen bonds stabilize the crystal structure.

15 صفحه اولThe fate of N2O consumed in soils
Soils are capable to consume N2O. It is generally assumed that consumption occurs exclusively via respiratory reduction to N2 by denitrifying organisms (i.e. complete denitrification). Yet, we are not aware of any verification of this assumption. Some N2O may be assimilatorily reduced to NH3. Reduction of N2O to NH3 is thermodynamically advantageous compared to the reduction of N2. Is this an e...
متن کاملReduced herbicide leaching by in situ adsorption of herbicide-micelle formulations to soils.
Aiming to reduce herbicide leaching, "in situ" adsorption of herbicide-micelle formulations to soils was explored. Sulfentrazone or metolachlor were solubilized in cationic micelles, and these herbicide-micelle formulations were applied to sandy and alluvial soils. Sulfentrazone adsorption to the soils was negligible; however, its adsorption via its solubilization in micelles and their adsorpti...
متن کاملEffect of planting covers on herbicide persistence in landscape soils.
Recent monitoring shows that the majority of urban streams in the United States are contaminated by pesticide residues, and the contamination is mainly due to runoff from residential landscapes. In this study we evaluated the effect of landscape planting on persistence of the herbicides 2,4-D and dicamba in soil under laboratory conditions. The herbicides exhibited substantially different persi...
