20%精喹禾灵乳油的低温稳定性研究

Study on the Stability of Quizalofop-p-ethyl 20% EC at Low Temperrature

探究了影响20%精喹禾灵乳油低温稳定性的因素,包括助溶剂、溶解温度等。结果表明,当乳化剂用量相同、助溶剂用量增加到一定量时,乳油的低温稳定时间延长;随溶解温度的升高,乳油的低温稳定性增强。

Influencing factors on the stability of Quizalofop- p- ethyl 20% EC at low temperature is studied including co- solvent and solution temperature. The results show that the stable period of EC is prolonged when the polarity of co- solvent decreas.The storage stability at low temperature strengthen when the solution temperature rise.
