carbamate (2): White amorphous powder (19 mg); IR (KBr): I>>max 3480, 3090, 2930, 1730, 1635, 1600, 1545 and 1485 cm-1; UV (MeOH): vmax 282 (4.01), 255 (4.12); 1H-and13C-NMR (Table-1); EIMS: m/z 342 (100%) [M]+, 313, 296, 270, 241, 223, 197 and 106; HR-EIMS: m/z 342.1579 [M]+(calcd.
Organophosphate and
carbamate compounds are typically used as insecticides, pesticides, petroleum additives and petrochemicals.
Ease of
carbamate formation was visually monitored by placing 3 g of adduct, or adduct BnOH mixtures, in 35 mm diameter wells of a 2 x 3 well plate.
Toxicology of organophosphate and
carbamate compounds.
The effect of mixtures of organophosphate and
carbamate pesticides on acetylcholinesterase and application of chemometrics to identify pesticides in mixtures.
In addition to these reactions and depending on the reaction conditions, various other compounds may precipitate, such as ammonium bicarbonate (N[H.sub.4]HC[O.sub.3]), ammonium carbonate [[(N[H.sub.4]).sub.2]C[O.sub.3]], ammonium
carbamate (N[H.sub.4]N[H.sub.2]C[O.sub.2]), and ammonium sesquicarbonate [[(N[H.sub.4]).sub.2]C[O.sub.3.sup.-]N[H.sub.4]HC[O.sub.3]].
Initially it uses databases to obtain information related to the main properties and characteristics of organochlorine pesticides, organophosphates and
Carbamate.
Carbamate was mainly used for livestock disease vector control, and organophosphate was used seasonally for crop pest control among a small proportion of households.
As demonstrated In Figure 1, the novel isocyanate-free chemistry developed for the preparation of urethane coatings at ambient temperatures results from the reaction of polyaldehydes with
carbamate functional polymers using an acid catalyst.
2), in
carbamate poisoning sinusoidal dilatation is major histopathological change, fatty changes is predominant among alcohol poisoning, and combined alcohol and insecticidal poisoning major histopathological changes are fatty change (Fig-3), combined centrilobular necrosis and fatty change, combined sinusoidal dilatation and fatty changes.
