具有改进的电导率和冷流动性的矿物油
摘要：
本发明公开了芳族化合物含量低于21重量％、水含量低于150ppm和电导率为至少50pS/m的矿物油馏分，其包含0.1至200ppm至少一种包括下式的结构单元的烷基酚-醛树脂(成分I)，其中R5是C1-C200-烷基或C2-C200-链烯基，O-R6或O-C(O)-R6，R6是C1-C200-烷基或C2-C200-链烯基，和n是2至100的数，和0.1至200ppm至少一种极性、油溶性含氮化合物(成分II)，在此排除这样的矿物油馏分，其中存在0.001-10ppm油溶性、有机磺酸铵盐。
摘要（英）：

The present invention provides a mineral oil fraction having an aromatics content of less than 21 %wt. and including a moisture content of less than 150 ppm and having a conductivity of at least 50 pS/m. The mineral oil distillate includes 0.1 to 200 ppm of at least one kind of alkylphenol-aldehyde resin represented by the formula, wherein R<5> is a C1-C5 alkyl or a C2-C200 alkenyl, O-R<6> or O-C(O)-R<6>, and R<6> is a C1-C200 alkyl or a C2-C200 alkenyl and n is 2 to 100 and 0.1 to 200 ppm of at least one kind of a polar and oil-soluble nitrogen compound.
