Definitions
- the invention relates to a process for the separation of Coumafos (O, O'-Diethyl-O "- (3-chloro-4-methyl-7-coumarinyl) thiophosphate) from beeswax by adsorption on activated carbon and subsequent pressure filtration.
- the mite Varroa jacobsoni causes the parasitosis known as varroasis Honeybee.
- the mite parasites the adult bee and its breeding stages. After a latency period of several years in which there are no clinical signs can be observed, the collapse of the People. Early diagnosis is essential for successful therapy of vitally important.
- For medical diagnosis and therapy of Varroatose was developed by Bayer AG in collaboration with the animal hygiene department Institute Freiburg Perizin® developed. W. Ritter,schen Institute for Animal Hygiene; "The varroasis of the honeybee, Apis mellifera, and its control with Perizin® ", Veterinary Medical News, Issue 1, p. 3; G. Elwert (2015)sund Publishing house Marburg-Lahn; 1986th
- the activated carbon prior to filtration brought into contact with the beeswax for at least 5 minutes.
- the pressure difference during the filtration is 4 to 6 bar. Due to the low solids concentration and the comparatively small particle size of the particles, one can speak of a clarification filtration in the present filtration task.
- Suitable pressure filters that offer sufficiently large filter areas are, for example, the plate pressure filter or the candle filter. Both are closed, discontinuous clarification filtration devices with adjustable pressure difference and automatic cake cleaning. Due to the compact arrangement of the plate-shaped or candle-shaped filter elements inside the pressure filter, filter areas of up to 100 m 2 can be realized.
- Such pressure filters are described, for example, in Ullmann's Encyclopedia of Industrial Chemistry, Sixth Edition, WILEY-VCH, Electronic Release 2001; Filtration, 8. Filtration Equipment, 8.3 Candle Filters and 8.5 Disk Filters.
- the amount of activated carbon is preferably 20 to 50 g per liter of liquid Wax.
- the activated carbon used should have the highest possible adsorption capacity and have the best possible filtration properties. adsorption capacity and filtration properties of the activated carbon are determined during manufacture the type of activation or the wording set. As particularly suitable the activated carbon CA 1® from the manufacturer Norit has been proven.
- the contact time between activated carbon and beeswax is preferably 30 to 90 min.
- Example 2 The procedure was as in Example 1, but with a contact time of 15 minutes. By increasing the dwell time from 15 min to 60 min, another one could Depletion from about 5 ppm to less than 1 ppm can be achieved. Immediate Filtration of the suspension after briefly distributing the powdered charcoal brings about a barely measurable reduction in the Coumafos content of approx. 20 ppm in beeswax.
