Pesticide requirements in line with the 21st century transformation of pesticides pilot compound and pesticide additives , the paper looking for on the basis of the original study , completed the synthesis of the work of the following three aspects : ( 1) to replace phenoxyacetic acid as raw materials , its acylation isothiocyanate, esterification, and then with 3 - (2 - furyl ) - 4 - Amino - 5 - mercapto - 1 ,2,4 - triazolo occur ring closure reaction to synthesize a series of nine were reported in the literature 3 - (2 - furyl ) -6 ( 2 ) to - substituted -1 ,2,4 - triazolo [ 3,4- b ] [1,3,4] - thiadiazin oxazole ( I ) ; containing strong suction the electron groups fluoroaniline hydrochloride and α- Octamolybdate four butylammonium [(Bu4N) 2 [α-Mo8O26] as the raw material , using DCC dehydration method , synthetic 4 were reported in the literature of six molybdate , fluoroalkyl aryliminium derivative ( II ) ; ( 3 ) a rosin derivative , sodium styrene sulfonate and acrylic acid as monomers, ammonium persulfate as initiator and sodium bisulfite initiator help agent , through orthogonal experiment to optimize the reaction conditions , the synthesis of a novel the terpolymer polymer dispersed agent ( III ) . By elemental analysis, infrared spectroscopy , NMR , MS , UV-visible spectroscopy to characterize the structure of the three series of target compounds , carried out a systematic analysis of their physical properties , spectral properties , reaction conditions , synthesis method and discussion. The target compound ( I ) , ( II ) , (III) the following structural formula : In order to further understand the spatial structure of the compound , and explored the relationship between the structure and nature of the compounds , sixth molybdate aromatic fluorinated series ( II ) the imine derivative conducted Single Crystal X-ray diffraction crystal structure determination . , (Ⅰ) and ( II) the two series , a total of 13 compounds were pharmacodynamic Ministry to the herbicidal activity of the initial general screening work commissioned by the National Southern Pesticide Research and Development Center ( Shanghai) , results showed that some of these compounds have good herbicidal activity. In this paper, the orthogonal experiment to optimize the reaction conditions of the series ( III ) , rosin derivatives , styrene sulfonate , acrylic acid and ammonium persulfate are four factors that impact on the performance of the product dispersed . The synthesized dispersant performance test results of various performance tests showed that such copolymers having a better dispersing ability .
