Process for the production of N-methylcarbamates: STR1 (wherein RO- is the radical of a substituted phenol or of a naphthol), wherein: in a first reaction step methylamine and diphenyl carbonate are reacted with each other, operating in the liquid phase and as a continuous process, in order to form phenol and phenyl-N-methylurethane; in a second reaction step phenyl-N-methylurethane, within the related reaction mixture outcoming from the first step, is thermally continuously decomposed, to yield a gaseous stream containing methyl isocyanate, from which the components different than methyl isocyanate are condensed off; in a third step the methyl isocyanate stream, outcoming from the second step, after an optional preliminary condensation, is continuously fed and contacted with a solution of a substituted phenol or of a naphthol in an inert organic solvent, containing a basic catalyst, to form N-methylcarbamate (I); N-methylcarbamate (I) is finally recovered from the reaction mixture outcoming from the third step.

Synthetic Route of 125-20-2, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 125-20-2, molcular formula is C28H30O4, introducing its new discovery.

Biodiesel is considered an important substitute of diesel oil. Traditionally, it is obtained by the transesterification of vegetable oils with methanol or ethanol, catalyzed by NaOH or KOH. Heterogeneous catalysts have been studied with the aim at facilitating and diminishing costs with purification stages. In the present work, the Na/Nb2O5 system was evaluated on the reaction of soybean oil with ethanol. It was verified, by DRX and IR, that the niobia calcined at 500C and impregnated with sodium underwent greater structural alterations than that treated at 300C. These modifications allowed the generation of basic properties on niobia surface (Hammett and CO2 adsorption /IR). This catalyst showed the highest conversion (30%) among the used materials. The method chosen for evaluating the catalysts yield was the 1H NMR spectroscopy.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 125-20-2 is helpful to your research. Synthetic Route of 125-20-2

Carbamates are poisonous pesticides which have been used widely in agriculture production for decades. Unlike other pesticides such as organophosphate, carbamate pesticides are not persistent in the environment however, their degradation is crucial due to their toxicity to living system. The World Health Organization, categorized carbamate pesticide as toxic, hazardous and restricted for use. Example of carbamates pesticides include Carbaryl, Aldicarb, Methomyl, Carbofuran, and Propoxur. They are extensively used to control many insect and pests of crops. Presently, there is significant awareness regarding the negative effects of pesticides due to their ability to pollute soil and water bodies. Most pesticides are readily degraded or metabolized by microbes. Carbamate pesticide degradation by microorganisms relies not only on the availability of microbes with suitable biodegradative enzymes, but also on the various ecological factors. This review-article outlines the present development in biodegradation of carbamate pesticides, their toxicity and enzymatic degradation as well as their degradative pathways.

Biodegradation of 6-methyl-2,3-dithiolquinoxaline cyclocarbonate or quinomethionate (Q1) by cucumber seedlings seems to confirm that the thiocarbonate linkage is disrupted during metabolism of the fungicide by the plant. The sulfur liberated is principally incorporated into sulphates and sulfur amino-acids, while the labeled (2,3-14C) quinoxaline nucleus is catabolized to 14CO2. This work also suggests that microorganisms can largely share in fungicide biodegradation when they are in the immediate environment of seedlings.

Novel ABI-III compounds were designed and synthesized based on our previously reported ABI-I and ABI-II analogues. ABI-III compounds are highly potent against a panel of melanoma and prostate cancer cell lines, with the best compound having an average IC50 value of 3.8 nM. They are not substrate of Pgp and thus may effectively overcome Pgpmediated multidrug resistance. ABI-III analogues maintain their mechanisms of action by inhibition of tubulin polymerization.

BACKGROUND: Insecticides are extensively used in China and may leach to groundwater, which is used as a source of drinking water in Northern China. However, the risk of insecticide leaching to groundwater and the subsequent risk to human health caused by the consumption of insecticide-contaminated drinking water remain unclear. RESULTS: A total of 336 predicted environmental concentrations (PECs) were simulated for 32 commonly used insecticides, and 171 PECs were calculated for 20 metabolites in six agricultural dry-land scenario locations of Northern China with eight target crops. In 264 of the 336 cases, the PEC in groundwater is ?0.1 mug L?1. Carbofuran, imidacloprid, trichlorfon and oxidative metabolites of aldicarb are the most leached chemicals in groundwater. The most vulnerable crop is cotton, whereas soil treatment is the most vulnerable application type. Urumqi and Weifang are the most vulnerable among the six scenario locations. Less than 3% of 336 cases show unacceptable risk of insecticide-contaminated groundwater, thereby requiring higher risk assessment and risk mitigation. The unacceptable cases are the leaching of carbofuran for cotton growing in Urumqi and Weifang, and leaching of metabolites of aldicarb in cotton and tobacco scenarios. CONCLUSION: Popular insecticides used in Northern China are generally safe to groundwater.
