Abstract

Kerosene-derived solvents that are substantially free of aromatic hydrocarbons and normal-paraffins provide useful solvent properties. Kerosene, a petroleum derived distillation fraction, is a complex hydrocarbon mixture of both aromatic and aliphatic hydrocarbons (normal-, iso-, and cyclo-/naphthenic-paraffins). Kerosene-derived solvent properties are a function of the kerosene and the crude-oil source. Despite kerosene variability, kerosene-derived solvents can be modified by physical and chemical means to tailor their properties for different formulation needs. The resultant solvents are useful in many applications, including pesticide formulations. This paper relates some key solvent properties to the general chemical classes of hydrocarbons contained in kerosene-derived solvents and gives an example using commercially available products.
