Embodiment 1

[0012] Example 1: Miscibility of isooctyl chlorofluoropyroxyacetate and butoxyethyl trichloropyroxyacetate ( Miscibility )

[0013] The test system in Table I below was prepared by blending molten isooctyl chlorofluoroacetate (about 65°C) into butoxyethyl chlorofluoroacetate at ambient temperature until isotropic ( isotropic). Miscibility behavior is reported in Table I.

[0014] Table I

[0015]

[0016] ＊ NM = Immiscible

[0017] PM = Partially miscible, crystallisation of isooctyl chlorofluoropyracetate can be observed

[0018] M = miscible, the system is isotropic

[0019] The test system in Table II below was prepared by blending molten isooctyl chlorofluoropyroxyacetate (about 65°C) into 2,4-D 2-ethylhexyl ester at ambient temperature until isotropic (isotropic). Miscibility behavior is reported in Table II.

Embodiment 2

[0031] Example 2: Emulsifiable Concentrate (EC)

[0032] Formulations A and B were prepared as follows. The molten isooctyl chlorofluoroacetate (approximately 65°C) was mixed into the chlorofluoroacetate butoxyethyl ester and the remaining ingredients with stirring at ambient temperature until an isotropic system was obtained.

Embodiment 3

[0044] Example 3: Emulsion Concentrate in Water (EW)

[0045] Formulation C was prepared as follows. Molten isooctyl chlorofluoroacetate (about 65°C) was mixed with stirring at ambient temperature into a preform of chlorofluoroacetate butoxyethyl, Amisoft HS-21P, Nikkol DGMS, Tween 61 and soybean oil. Blend in the preblend oil phase until isotropic. The mixed oil phase was vigorously mixed with a premixed aqueous phase formed of water, Proxel GXL, sodium dihydrogen phosphate, disodium hydrogen phosphate and propylene glycol until the entire system was homogeneous.

Abstract

This invention relates to formulations of fluroxypyr meptyl ester with C4-C8 esters of triclopyr, 2,4-D or MCPA that are free of aromatic hydrocarbon solvents.

Description

[0001] This application claims priority from US Provisional Patent Application 61 / 000,250, filed on October 24, 2007. Technical field [0002] The present invention relates to C of fluroxypyr meptyl ester and triclopyr 4 -C 8 Ester, C of 2,4-D(2,4-D) 4 -C 8 Ester or C of 2-methyl-4-chloro(MCPA) 4 -C 8 Ester herbicidal preparations. More specifically, the present invention relates to the C 4 -C 8 Esters, 2,4-D C 4 -C 8 Ester or C of 2methyl 4 chloride 4 -C 8 Ester preparation, which does not contain aromatic hydrocarbon solvents. Background technique [0003] In today's agrochemical market, in order to achieve optimal control profiles, efficacy and delivery efficiency, it is increasingly common to design formulations containing multiple active ingredients together with the solvents, safeners and / or excipients required for these active ingredients , which makes the stability of formulations increasingly challenging. [0004] Fluroxypyr is a known effective herbici...
