The process according to claim 3, where in step b an aqueous suspension of pyraclostrobin is added, where pyraclostrobin is essentially present in the form of its crystalline modification IV. A microscopic sample of the suspension indicated complete crystallization.

Thus further comminution after addition of the aqueous suspension to the emulsion is generally not required. This is the volume of syneresis liquid clear liquid on top divided by the total sample volume expressed as a percentage. Likewise, the term poly-ethoxylate-co-propoxylate refers to a polyether radical derived from a mixture of ethyleneoxide and propylenoxide.

Subsequently the formed emulsion was cooled down to 40 0 C while high shear mixing was still continued. Anionic surfactants include in particular the sodium, potassium, calcium or ammonium salts of.

In case of pyraclostrobin comminution is performed at temperature in the range from 45 to 90 0 C, in particular from 50 to 80 0 C. Forward Favorites Print Share. In addition, the aqueous suspensions obtained by the process according to the invention can be formulated with conventional binders, for example aqueous polymer dispersions, alox resins, for example water-soluble alkyd resins, or waxes, in par- ticular, if the composition is intended for seed treatment purposes.

The aqueous suspension, which is added to the aqueous emulsion of the pesticide compound, may contain one or more surfactants and may further contain further formulation additives.

Atlox™ 4913

The oil phase used can range from paraffinic mineral oils, hydrocarbon aromatic solvents, diesel oil, kerosene, vegetable atlx and fatty acid esters. In a very preferred embodiment of the present invention, the surfactant additionally comprises at least one non-polymeric surfactant.

PAO usually ranges from 1: After 15 seconds, a microscopic sample indicated complete crystallization.

In a likewise preferred embodiment of the present invention, the emulsion comprises at least one anionic polymeric surfactant having polyether side chains, in particular an anionic polymeric surfactant which is a polymer having a carbons backbone carrying carboxylate groups and polyether side chains, especially an anionic polymeric surfactant of the group c.


Preferred hydrophobic monomers are selected from vinylaromatic monomers such as styrene monomers and C2-Ci2-monolefines. Amongst non-ionic surfactants those of the groups c. Despite the aforementioned advantages associated with the usage of SCs and FS’s, there is a number of atloz known to the skilled person which are sometimes encountered with SCs and FS’s as a result of settling during prolonged storage or storage at elevated temperatures, the resistance of settled particles to re-suspension and the formation of crystalline material upon storage.

Country of ref document: As a consequence, the formulations may be difficult to handle and the bioefficacy may be inconsistent. The amount of sample was 5 to 10 mg. This process is called syneresis: In preferred embodiments of the invention, the first pesticide compound is pyraclostrobin and the further pesticide compound is selected from the group of amide fungicides as mentioned above, in particular from the group consisting of penflufen, seda- xane, penthiopyrad, fluxapyroxad and N- 4′-trifluoromethylthiobiphenylyl methyl- 3-difluoromethyl-1 H-pyrazolecarboxamid.

The pesticide compound can be any organic or inorganic pesticide compound, which is suitable as a co-pesticide for the pesticide compound which is contained in the aqueous suspension obtained in step b. Such average particle diameters can be determined by dynamic light scattering usually performed on diluted suspensions containing from 0.

Thus, the water may be preheated to 9413 desired temperature or the melt is heated to a temperature that upon mixing the desired temperature is achieved. In a preferred embodiment, the surfactant c. A process for preparing an aqueous suspension of an organic pesticide compound. Suitable 49913 or dyes for atox treatment formulations are pigment blue As mentioned above, the further pesticide compound may be selected from any pesticide compound which is known to be suitable for co-formulation with the first pesticide compound.

As a result, agrochemical formulations are becoming more complex, often requiring enhanced 413 and inclusion of multiple a. The obtained formulation contained Due to work on overcoming resistance or differentiating products in the market, there is increasing interest in the synthesis of tailor-made polymeric surfactants to xtlox advanced or specific roles.

Seed crystals of modification I and modification IV were sprinkled on the amorphous layer and the crystals were observed in 15 minute intervals. It is thus possible to perform the process of the present invention as a simple batch process but also as a semi-continuous process or a continuous process simply by taking a portion of the aqueous suspension formed when the aqueous suspension is added to the aqueous emulsion and recycling this portion into step b of the claimed process.


In another particular preferred embodiment of the inven- tion, the emulsion comprises at least one non-ionic polymeric surfactant, in particular a non-ionic polymeric surfactant of the groups c. Although not as well-defined as small-molecule surfactants, polymeric surfactants offer greater opportunities in terms of flexibility, diversity and functionality. Thus, a particular preferred embodiment of the invention is directed to a process, where the pesticide com- pound contained in the emulsion of step a is pyraclostrobin and where the crystalline pesticide compound present in the aqueous suspension that is added in step b is essentially crystalline pyraclostrobin, in particular pyraclostrobin being essentially present as its crystalline form IV.

Into 55 grams of water, 7 grams of ethylene glycol, 5 grams of surfactant 2 and 3 grams of surfactant 4 were dissolved and then mixed until homogeneous. Though aqueous suspension concentrates of pyraclostrobin have been described in the art, they are difficult to prepare by conventional methods not least because of the low melting point of pyraclostrobin.

For example, enhancing emulsion stability through increased steric hindrance of irreversible flocculation. The nature of the further pesticide compound will naturally depend on the pesticide compound contained in the aqueous suspension obtained in step b.

However, surface properties of the particles are critical to the effectiveness of the polymer. This is especially true in the light of recent atllox in controlled living radical polymerisation chemistry, as exemplified by atom transfer radical polymerisation ATRP and, to a lesser extent, reversible addition atlo transfer RAFT polymerisation.

Into 40 kg attlox water, 10 kg of propylene glycol, and 5 kg surfactant 2 were dissolved and then mixed until homogeneous.
