 ****************************************************************************

 * WARNING - The entered chemical is a Quaternary Ammonium Compound (QAC). *

 *   Adsorption of QACs seem to occur mainly by an ion-exchange mechanism *

 *   and depends on cation-exchange capacity of the sorbent and variety of *

 *   other parameters (Boethling, 1994). The training set for the Koc    *

 *   estimation of this program did not include any QACs. Therefore, the *

 *   Koc estimate is outside the program's prediction domain.             *

  ********************************************************************

  *                           NOTE:                                *

  * The Koc of this structure may be sensitive to pH! The estimated *

  * Koc represents a best-fit to the majority of experimental values *

  * however, the Koc may vary significantly with pH.                *
