“…The analysis has been applied to cattle dips (445), kerosine solutions (113), commercial sprays (111), and mixtures with DDT (461,462). The method has also been used to check the values obtained for the y-isomer by the dielectrometric method (303), to estimate the free energy change of the y-isomer (373), to follow its formation in the chlorination of benzene (117), and to compare half-wave potentials with insecticidal activities (465).…”
