Abstract
Official abstract text for this publication.
Provided is a lubricant for metal working comprising a vinylidene compound having 12 to 64 carbon atoms obtained by oligomerizing α-olefins, having 4 to 20 carbon atoms, using a metallocene catalyst. The lubricant for metal working is excellent in a workability and a surface detergency property and has a high flash point and can reduce environmental pollution.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of metal working comprising working a metal in the presence of a lubricant comprising: 5 to 50% by mass of a vinylidene compound relative to 100 mass % of the lubricant, and a base oil, wherein said vinylidene compound is 1-Decene dimer manufactured in the presence of a metallocene catalyst, and wherein the metal working comprises cutting, grinding, or plastic working. 2. The method of claim 1 , wherein the lubricant fur…
