A poly(neopentylpolyol) ester composition is produced by reacting a neopentylpolyol having the formula: wherein each R is independently selected from the group consisting of CH3, C2H5 and CH2OH and n is a number from 1 to 4, with at least one monocarboxylic acid having 2 to 15 carbon atoms in the presence of an acid catalyst and at an initial mole ratio of carboxyl groups to hydroxyl groups of greater than 0.5:1 to 0.95:1 to form a partially esterified poly(neopentylpolyol) composition. Then the partially esterified poly(neopentylpolyol) composition is reacted with additional monocarboxylic acid having 2 to 15 carbon atoms to form a final poly(neopentylpolyol) ester composition.

The invention relates to novel lubricity enhancing additives, to a method for producing the same, and to the use thereof.

There is disclosed a process for transporting fracture fluid additives underground to oil and gas wells by attaching a fracture fluid additive to an ion exchange resin and flowing the ion exchange resin underground and thereafter releasing the frac fluid additives from the ion exchange resins and also there is provided the use of an ion exchange resin as a proppant and a frac fluid lubricant.

本发明涉及一种润滑油组合物及其制备方法，尤其是一种发动机润滑油的组合物，同时还涉及其制备方法，属于润滑油技术领域。本发明在基础油加入烷基萘和环烷基光亮油，同时添加了含氮硫代磷酸钼添加剂、硼化的无灰分散剂、加氢苯乙烯-异戊二烯粘度指数改进剂(Infineum SV261)等，通过各组分间的相互协作，使润滑油组合物具有突出的橡胶密封圈的相容适应性，防止机油泄露；防止燃气的窜气，提高了发动机的动力性；降低的机油耗，改善了发动机排放性，延长了机油的换油期及发动机使用寿命，特别适用于行驶10万公里以上或大修过的车辆。
