高沸点重芳烃溶剂取代农药乳油中二甲苯溶剂的研究

Study on the High Boiling Aromatic Solvent Insteading of Xylene Solvent in Pesticide EC

本文通过比较高沸点重芳烃溶剂、二甲苯、生物质溶剂松香基植物油在毒死蜱40%乳油、毒死蜱·扑虱灵42%乳油、丙环唑25%乳油、精喹禾灵8.8%乳油的溶解性能及药效,认为高沸点重芳烃溶剂在以上代表产品中溶解性能与二甲苯相当,与常规乳化剂配伍性良好,乳化性能良好,采用常规非离子表面活性剂与阴离子复配可配制出合格产品。在防治效果上高沸点重芳烃溶剂体系明显优于二甲苯体系的防治效果,其价格相比二甲苯略低或相当,具有推广使用价值。

In this paper, by making a comprison of solubility and efficacy between the high boiling aromatics solvents, xylene and biomass of rosin based plant oil in chlorpyrifos 40% EC, chlorpyrifos＇buprofezin 42% EC, propieonazole 25% EC, quizalofop-p-ethyl 8.8% EC, it was concluded high boiling point heavy aromatic solvents in the above representative products had the same solubility as xylene, and performed well with conventional emulsifiers and had good emul- sifying properties. Moreover, they could be used to produce qualified products by formulating with conventional nonionic surfactant and anionic surfactant. The control effect of high boiling aromat- ics solvent system is better than that of xylene system, and its price is slightly lower than xylene or equivalent, therefore, the high boiling aromatics solvents are with the promotion of value.
