Patent number: 8283508Abstract: The present invention is a method for producing an aromatic compound by substituting the sulfonic acid group in a sulfonic acid aromatic-ester with a hydrogen atom in the presence of a platinum group metal catalyst, wherein an alkali metal carboxylate and/or an ammonium formate are made to coexist in the system. According to the present invention, an aromatic compound where the sulfonic acid group in a sulfonic acid aromatic-ester is substituted with a hydrogen atom, can be produced efficiently with good operability without using metal magnesium.Type: GrantFiled: August 1, 2008Date of Patent: October 9, 2012Assignee: Ube Industries, Ltd.Inventors: Koji Abe, Yoshihiro Ushigoe, Yuichi Kotou, Ken Ikuno, Takashi Hosomi, Toyoaki Ihara

Patent number: 6881522Abstract: A nonaqueous electrolytic solution for lithium secondary batteries. When the nonaqueous solvent comprises a combination of an ester of a tertiary carboxylic acid and a cyclic carbonate such as propylene carbonate or ethylene carbonate, a lithium salt having a fluorine atom is preferably used as the electrolyte salt. In this case, the ester of a tertiary carboxylic acid is preferably used in a relatively small amount, especially in an amount of about 0.5 to 35 wt. % based on the nonaqueous solvent.Type: GrantFiled: August 13, 2001Date of Patent: April 19, 2005Assignee: Ube Industries, Ltd.Inventors: Toshikazu Hamamoto, Koji Abe, Yoshihiro Ushigoe, Yasuo Matsumori
