Analytical methods for the determination of the molluscicide N-tritylmorpholine in water.
A colorimetric method has been developed for the determination of the molluscicide N-tritylmorpholine (Frescon, WL 8008) in water. The method is based on the production, from N-tritylmorpholine in strong acid, of the typical yellow colour of the tritylcarbonium ion.Two procedures are recommended for field use, neither of which distinguishes between N-tritylmorpholine and its hydrolysis product triphenylcarbinol (triphenylmethanol). A more precise laboratory procedure is described, by means of which both N-tritylmorpholine and triphenylcarbinol can be determined separately.
