Definitions
- the present invention relates to granules of triazines and their preparation.
- Toltrazuril (1-methyl-3- (3-methyl-4- (4- (trifluoromethyl) thio) phenoxy) phenyl) -1,3,5-triazine-2,4,6 (1H, 3H, 5H) trione ) is a known active ingredient against coccidia. It is usually used in the form of aqueous solutions or suspensions. These solutions are difficult to use for many areas of application.
- the present invention relates to granules of triazines of the following composition
- the granules are produced by premixing components a) to d) in a suitable mixing or stirring vessel and spraying them with a solution of polyvinylpyrrolidone. The granules are then dried and, if necessary, sieved.
- a dust-free, dry, easy-flowing and easy-to-dose granulate is obtained.
- These granules are preferably used for the treatment of coccidiosis diseases in cats and other pets and hobby animals.
- the domestic and hobby animals include dogs, rabbits and ornamental birds
- the granulate is used by mixing it with solid, semi-solid or liquid feed.
- feed which is mixed with the granules according to the invention is also easily taken up by sensitive animals.
- active substances which may be mentioned are symmetrical 1,3,5-t ⁇ az ⁇ n-2,4,6 (1H, 3H, 5H) -t ⁇ ones such as toltrazuril, unsymmetrical l, 2,4-t ⁇ az ⁇ n-3,5-d ⁇ one such as diclazu ⁇ l (2.6 -D ⁇ chlor- ⁇ - (4-chlorophenyl) -4- (4,5-d ⁇ hydro-3,5-d ⁇ oxol, 2,4-t ⁇ az ⁇ n-2 (3H) -yl) - phenylacetomt ⁇ l)
- Toltrazuril is preferred.
- the active ingredients are used in amounts of 0.5 to 10, preferably 1 to 5, particularly preferably 2 to 4% by weight
- starch such as potato starch, corn starch, and cereal starch
- starch is preferred with 10 to 40, preferably 20 to 30, particularly preferably around 25% by weight
- Lactose is used as a monohydrate in concentrations of 30 to 60, preferably 50 to 60, particularly preferably around 60% by weight.
- Polyvinylpyrrolidone is preferably used as a medium-molecular PVP with a K value from 24 to 32. Particular preference is given to PVP with a K value from 24 to 30, particularly preferably from 25.
- Water is preferably used as the solvent for PVP also called organic solvents alone or in a mixture with water
- a K value of 25 corresponds to a weight average molecular weight of 28,000 to 34,000.
- the K value characterizes the average molecular weight
- PVP is preferably used in a total amount of 10 to 30% by weight
- the grain size distribution is between 40 and 400 ⁇ , preferably between 80 and
- the granules according to the invention are produced in solid mixers, preferably in fluidized bed granulators
- the individual components are mixed homogeneously at room temperature.
- the mixture is then mixed with a 10 to 50%, preferably 30 to
- aqueous PVP solution sprayed and optionally sprayed with further water.
- the granulation takes place at 20 to 50 ° C., preferably at 25 to 40 ° C.
- the granules are then dried at about 40 to 70 ° C., preferably at 50 to 60 ° C.
- the preheating phase until the supply air temperature reaches 25 to 40 ° C should be 2 to 4 minutes.
- the premix is granulated with 35 to 40 ° C supply air, 22 to 30 ° C exhaust air and a supply air volume of 150 to 200 m 3 / h while spraying 30 g spray solution / minute at 2 bar spray pressure
- the PVP pre-solution from production 1 is sprayed
