Polyhydroxyl functional compounds that contain an all hydrocarbon backbone, wherein all of the hydroxyl groups are bonded to a primary carbon atom, are prepared through the reaction of an alpha, omega-terminal diol having a total of from about 6 to about 42 carbon atoms terminated with a mono-ol having a total of from about 4 to about 42 carbon atoms. The polyols can be used as additives in hydrocarbon oils, drilling fluids, industrial and automotive lubricating fluids, dispersants, engine lubricants, greases, coatings, adhesives, and also in magnetorheological fluids to improve various properties such as dispersion, wear protection, reduction of friction, high temperature stability, and improved aging.
通过将总共约6至42个碳原子的α,ω-末端二醇与总共约4至42个碳原子的单醇反应制备含有全碳氢骨架的多羟基功能化合物,其中所有羟基均与一级碳原子键合。这些聚醇可用作烃类油、钻井液、工业和汽车润滑油、分散剂、发动机润滑油、润滑脂、涂料、粘合剂以及磁流变流体的添加剂,以改善各种性能,如分散性、耐磨保护、减少摩擦、高温稳定性和改善老化。
