摘要： A solvent-free process for making a polyol fatty acid polyester composition useful for preparation of polyurethanes is described. These compositions are preferably made by reaction of a natural oil (from plant or animal) with a multi-functional hydroxyl compound derived from a natural source, such as sorbitol, in presence of an alkali metal salt or base such as potassium hydroxide as a catalyst which also acts to saponify the reaction mixture. The hydroxyl content of the prepared composition depends on the amount of the multi-functional hydroxyl compound used in the preparation. In another embodiment, the hydroxyl groups of these compositions are reacted with an isocyanate, such as the polymeric diphenylmethane diisocyanate (also known as 4,4′-diphenyl methane diisocyanate, or MDI) to form polyurethanes in a conventional manner.

摘要： A lubricant composition is disclosed that includes (a) a machining oil and (b) an exfoliated graphite nanoparticle (EGN) material stably dispersed in the machining oil. The lubricant composition is a stable suspension and is suitable for use as a liquid lubricant in a Minimum Quantity Lubrication (MQL) process. In the MQL process, the lubricant composition is applied/transferred to a worksite in the form of a mist. The presence of the EGN material in the lubricant composition provides high-temperature stability and lubricity under MQL conditions. A very small amount is transferred especially at high cutting speeds where the mist of the machining oil evaporates, but the EGN material remains on the surface to provide lubricity. Any operation involving machining can benefit from this lubricant composition. The method provides important benefits of reducing chipping on cutting tools and providing the additional lubricity especially when the cutting become very hot and thus extending tool life.
摘要翻译：公开了一种润滑剂组合物，其包括（a）机械油和（b）稳定分散在机械油中的剥离石墨纳米颗粒（EGN）材料。润滑剂组合物是稳定的悬浮液，适用于最小数量润滑（MQL）工艺中的液体润滑剂。在MQL工艺中，将润滑剂组合物以薄雾的形式施加/转移到工地。 EGN材料在润滑剂组合物中的存在可在MQL条件下提供高温稳定性和润滑性。特别是在加工油雾蒸发的高切削速度下，非常少量的转移，但是EGN材料保留在表面上以提供润滑性。任何涉及加工的操作均可从该润滑剂组合物中受益。该方法提供了减少切削刀具切屑和提供附加润滑性的重要优点，特别是当切削变得非常热并因此延长刀具寿命时。
