摘要：
A dielectric fluid for the machining of metal by spark erosion which contains saturated aliphatic hydrocarbons with a proportion of aromatic hydrocarbons which is lower than one percent in weight and to which an additive is added, wherein organic substances from the group of anthraquinone derivatives are added as the additive in a concentration of maximally one percent in weight.
