log pow koeficijent raspodele oktanol/voda (log Pow) Explanation: http://www.oecd.org/dataoecd/17/36/1948177.pdf OECD GUIDELINE FOR TESTING OF CHEMICALS Partition Coefficient (n-octanol/water), High Performance Liquid Chromatography (HPLC) Method 1. The partition coefficient (P) is defined as the ratio of the equilibrium concentrations of a dissolved substance in a two-phase system consisting of two largely immiscible solvents. In the case of n-octanol and water, ... ... 3. Pow values in the range log Pow between -2 and 4 can be experimentally determined by the Shake-Flask method (OECD Test Guideline 107). Pow values in the range log Pow between 0 and 6 can be estimated using high performance liquid chromatography (HPLC) (1) (2) (3) (4). The HPLC method requires a preliminary estimation of Pow , generally done through calculation. Calculation methods are briefly discussed in the Annex to this guideline. http://www.nikkakyo.org/ontai/merumaga/Challenge/OECD/TG_107... Partition Coefficient (n-octanol/water): Shake Flask Method ... 2. POW values in the range log POW between -2 and 4 (occasionally up to 5) can be experimentally determined by the method set out in this guideline (1)(2). POW values in the range log POW between 0 and 6 can be estimated using high performance liquid chromatography as is set out in Guideline 117. Before deciding on what procedure to use, a preliminary estimate of the POW should be obtained from calculation (see the annex to Guideline 117), or where appropriate from the ratio of the solubilities of the test substance in the pure solvents (3). http://www.agrosava.com/msds/fungicidi/cabrio_top_msds.pdf koeficijent raspodele oktanol/voda (log Pow) http://www.cecra.dh.pmf.uns.ac.rs/pdf/treciseminar/Sudbina o... koeficijent raspodele oktanol/voda -------------------------------------------------- Note added at 3 hrs (2010-06-28 20:41:58 GMT) -------------------------------------------------- Da budem preciznija, kod vas je u pitanju koeficijent raspodele n-oktanol/voda (log Pow) http://www.agrosava.com/msds/fungicidi/cabrio_top_msds.pdf Koeficijent raspodele n-oktanol / voda (log Pow): |
