Abstract
Official abstract text for this publication.
It is an objet to provide an oil extraction agent that is used in an oil concentration meter, that can be manufactured at low cost, that has a high oil extraction efficiency, and whose burden on the environment is small. Trimeric or higher oligomers of chlorotrifluoroethylene are contained in the overall oil extraction agent in a range between 35% by weight or more and 100% by weight or less.
First claim
Opening claim text (preview).
What is claimed is: 1. A purified oil extraction agent containing trimeric or higher oligomers of chlorotrifluoroethylene in a range between 35% by weight or more and 100% by weight or less, wherein surfactant impurities contained in the purified oil extraction agent are 10 mg/L or less, wherein L indicates liters of the purified oil extraction agent and mg indicates milligrams of impurities in the purified oil extraction agent, the purified oil extraction agent causes phase separation to occur in a period of 10 minutes or less, and the surfactant impurities are by-products of polymerization reactions. 2. A purified oil extraction agent whose principal constituent is formed by trimeric or higher oligomers of chlorotrifluoroethylene, and whose viscosity at 25° C. is between 1.30 cSt or more and 3.00 cSt or less, wherein surfactant impurities contained in the purified oil extraction agent are 10 mg/L or less, wherein L indicates liters of the purified oil extraction agent and mg indicates milligrams of impurities in the purified oil extraction agent, the purified oil extraction agent causes phase separation to occur in a period of 10 minutes or less, and the surfactant impurities are by-products of polymerization reactions. 3. The oil extraction agent according to claim 1 , wherein the oligomers are trimers. 4. The oil extraction agent according to claim 2 , wherein the oligomers are trimers.
