Formula Study Of25%Oxadiargyl Oil Miscible Flowable Concentrate(OF)

This article detailed that a pilot study of formulation and process of25%oxadiargyl Oil miscible flowable concentrate, the physical and chemical characters ofthe preparations were determined.The main course of study were summarized asfollowing:1.Soybean oil which matched with OF was screened from methyl oleate、theesterification of soybean oil,soybean oil and esterification of turpentine oil.2.Emulsifier,despersing agent,thickener and other components of oil suspensionconcentration were screened and confirmed by the optimized combinationtests.Emulsifier A and dispersing agent B,organic bentonite,and anti-caking C wereselected as auxiliary agent of oil suspension concentration.3.To determine the optimal formulation of OF was consisted of oxadiargyl25%,emulsifier A17%,despersing agent B3%,organobentonite0.8%,anticakeingagent C0.8%and with soybean oil to make up100%.4.To determine the process: the pre-treated oxadiargyl,emulsifier,dispersant andsoybean oil were mixed,then,the anti-cakingagent and pre-treated thickner weremixed,to mix the raw materials with high shear emulsifying machine,with the ratio ofmedia being1:1and grinding2h.Finally,to got sample,the liquid was isolated anddetect the indicators.5.Oil suspension of the indicators were measured in accordance withstandard,and measured indicators were conformed with technical standards of the oilsuspension.
