    Abstract

    A study was conducted to evaluate the cold temperature behavior of various pesticide solutions as the chemical composition of the solvents varied. Solutions of seven pesticides in solvents containing primarily: (1) C9 and (2) C10 alkylbenzene and (3) C11–12 alkylnaphthalene, were prepared and observed for precipitation between ambient and -10 °C in 5 °C steps. Of the aromatic hydrocarbon fluids tested those containing C11–12 alkylnaphthalene compounds were the best solvents for the pesticide active ingredients tested. Removal of naphthalene from the C10 alkylbenzene and C11–12 alkylnaphthalene fluids did not adversely affect the solvency of the resultant pesticide solutions.
