摘要
研究了1,4-丁二醇双磺基琥珀酸异辛酯钠(GSS462)的性能及其应用情况,结果表明,其临界表面张力(γCMC)20.9 m N/m、临界胶束浓度(CMC)3.25×10-4 mol/L、乳化力16.6 min(1.0%)、渗透力4.5 s、耐硬水能力24.3 min;毒性较低,为弱致敏物;不具有爆炸性,撞击敏感度试验结果为"-"。GSS462可作为分散剂(添加量2%)用于制备50%多菌灵悬浮剂,入水分散性好,悬浮率达89%,研磨过程中泡沫很少。GSS462用于配制40%腈菌唑EW,配方为1%GSS462+7%TX-10+3%丙三醇;用于配制10%苯醚甲环唑EW,配方为1%GSS264+6%OP-10+3%丙三醇。在烷基糖苷(APG)中引入少量的GSS462,用于制备草甘膦铵盐和异丙胺盐水剂,能明显降低制剂的表面张力和提高润湿性,作为草甘膦专用助剂已应用于生产。
This paper studies the performance of 1, 4-butylene glycol double sulfosuccinate sodium isooctyl（GSS462） and its application. The result shows that the critical surface tension of GSS462 is 20.9m N/m, the critical micelle concentration（CMC） is 0.325×10-4mol/L, the emulsifying ability is 16.6min（1.0%）,the osmotic force is 4.5s, and the hard water resistance is 24.3min. GSS462, as a weak sensitizer, has low toxicity, it is not explosive and its impact sensitivity test result is ＂-＂. GSS462 can be used as a dispersant（adding amount 2%） for the preparation of 50% carbendazim suspension agent, the water dispersion is good, the suspension rate is up to 89%, and the foam is little in the grinding process. GSS462 can be used for the preparation of 40% myclobutanil EW, the formula is 1% GSS462 plus 7%TX-10 plus 3% glycerol; when it is used for the preparation of 10% difenoconazole EW, the formula is 1% GSS264 plus 6% OP-10 plus 3% glycerol.Introducing a small amount of GSS462 in APG for the preparation of glyphosate ammonium salt and the isopropyl amine salt of water, can significantly reduce the surface tension of the preparation and improve the wettability, and as a glyphosate special additive, it has been applied in the production.
