短句来源
    The methomyl was determained by gas chromatograph using flame-photometric detector. The detection limit and the minimum detectable concentration of methomy in wheats and corns were 0.1ng amd 0.025mg/kg,respectively. The average recoveries of mothomyl as added to wheats and corns were in the tange of 95.5%~102.3%.

  methomyl
The interaction of pesticides with humic compounds (humic and fulvic acids) and with their metal complexes was studied potentiometrically and radiometrically, using the pesticides Aldicarb and Methomyl, and the herbicide Ametryne.
      
The results indicated that Aldicarb, Methomyl, and Ametryne form stable complexes with humic acid (HA) and fulvic acid (FA).
      
The complexation strength increases in the order Aldicarb ≤ Methomyl >amp;lt; Ametryne.
      
The complexes of Aldicarb and Methomyl with HA and FA are stronger than the metal humate/fulvate complexes with Co2+, Zn2+, and Sr2+, and these pesticides displace the metal ions.
      
The complexation of Aldicarb and Methomyl with humic compounds causes the release of radionuclides (60Co, 65Zn, 90Sr) from the soil organic matter to the solution.

A modified procedure for synthesizing methomyl was reported in this article. In the procedure described, all reactions take place easily under normal pressure. The optimum conditions of reactions have been investigated in some detail. A reaction mechanism was also suggested.

提出一种合成Methomyl的改良法。该方法的特点是反应可在常压下进行。对常压反应的优宜条件作了系统研究,并讨论了反应机理。

This paper describes a two-phase method applied to the synthesis of methomyl.In this method,the condensation reaction between methylmcrcaptoacetaldoxime and methvlcarbamyl chloride takes place at the interface of the two-phase,thus the hydrolysis of methylcarbamyl chloride can be restrained,and higher yield of the product can be obtained.

报道一种合成Methomyl的两相法。此法能使甲硫基乙醛肟与甲胺基甲酰氯之间的缩合反应在两相界面上进行,从而有效抑制酰氯的水解,并使收率明显提高。

A method of gas chromatographic analysis was presented for methomyl in wheats and corns.Methomyl was extracted from samples with ethyl acetate.The solvent was evaporated in 60℃ water bath with rotary-evaporated instrument.Extracts were purified through water liquid-petroleum leve partitioning,and then the methomyl was extracted from water phase with CHCI3.The CHCI3 was evaporated in 60℃ water bath with rotary-evaporated intrument.The methomyl was determained by gas chromatograph using...
