Coumarin,3-chloro-7-hydroxy-4-methyl-, O-ester with O,O-diethyl phosphorothioate (8CI) - Analysis and Application of synchronous fluorescence spectra of carbaryl and fly poison phosphorus
from VIP

Zhang , pan Junhui , Ni Yongnian
Abstract:
The fluorescence behavior of carbaryl and muscarinic phosphorus was studied. It was found that the two pesticides could produce strong fluorescence in the Britton-Robinson buffer medium of pH 3.0, but the spectra overlapped with each other, when the synchronous fluorescence scanning is carried out with the wavelength difference Δ & lambda;= 60 nm, their synchronous fluorescence spectra are well separated, and the synchronous fluorescence peak (expressed as the excitation wavelength) located at 280 and 322 nm, respectively, which can be used for quantitative determination at the same time. The linear ranges of carbaryl and muscarinic phosphorus were 0.016-0.384 μg · mL-1 and 0.016-0.320 μg · mL-1, respectively. The detection limits were 0.015 and 0.010 μg · mL-1, respectively. Mixed sample analysis without separation, the method is simple and rapid, for the determination of vegetables, fruits, rice and water samples, with satisfactory results.

Coumarin,3-chloro-7-hydroxy-4-methyl-, O-ester with O,O-diethyl phosphorothioate (8CI) - Method for preparation of muscarinic phosphorus by aqueous phase method
from Baidu Library Application (patent) number:
CN200910010046.0
application date:
2009-01-09
Public/Announcement Number:
CN101671368A
Public/announcement date:
2010.03.17
applicant (patent):
Liaoning Phoenix silkworm factory
inventor:
Zhang Huichun , Wang Lishi , bull , Yang Jinchen
National and provincial code:
CN210682
Abstract:
The invention belongs to the field of chemical insecticidal agent synthesis technology, in particular to A method for preparing fly poison phosphorus by an aqueous phase method, which can be carried out in sequence according to the following steps:(A) feeding: adding water into A reaction kettle, start the stirrer, then put the acid binding agent, 3-chloro-4-methyl-7-hydroxycoumarin and phase transfer catalyst, and add ethyl chloride;(B) temperature control: After feeding, react at room temperature, then raise the temperature to 50~80 ℃, react for 20~150 minutes, discharge;(C) discharge, washing and drying: discharge into the vacuum filter, filter the wastewater, the target product, muscarinic phosphorus, is washed to Neutral with clean water and then sent to a drying chamber for temperature control and drying. The reaction temperature is low, the reaction time is short, the yield is high, the use of a large number of organic solvents is avoided, the flammable and explosive hidden danger is eliminated, and the Environmental Protection efficiency is remarkable.
