  • Publication number: 20200399207
    Abstract: A method for manufacturing a higher purity nitrile solvent by purifying a nitrile solvent containing an impurity, e.g an imine. The nitrile solvent may contain an imine and a conjugated diene, a carbonyl compound, or a high-boiling material as impurities. A method for purifying a nitrile solvent, such as isobutyronitrile, including bringing nitrile solvent containing an imine, e.g., as an impurity, into contact with an acidic aqueous solution having a pH of 3 or less, such as hydrochloric acid; bringing the nitrile solvent having been contacted with acidic aqueous solution into contact with an aqueous sodium hydrogen sulfite solution; bringing the nitrile solvent having been contacted with the aqueous sodium hydrogen sulfite solution into contact with an alkaline aqueous solution, such as an aqueous sodium hydroxide solution; and distilling the nitrile solvent having been contacted with the alkaline aqueous solution.

  • Patent number: 10749284
    Abstract: A connector includes a male terminal, a housing having a housing portion that houses the male terminal, and a pressing member arranged in the housing portion. A female terminal having a proximal portion and a contact segment formed in a cantilever-like shape and extending from the proximal portion, is inserted into the housing portion. The pressing member holds the contact segment of the female terminal that is inserted into the housing portion between the pressing member and the male terminals, elastically deforms the contact segment, and presses the contact segment toward the male terminal.
