  • Patent number: 6392090
    Abstract: A process for preparing a hydroxybenzoic acid is herein disclosed which comprises reacting a phenol with an alkali metal compound by the use of an aprotic polar organic solvent as a reaction solvent to form an alkali metal salt of the phenol, and then reacting this alkali metal salt with carbon dioxide to obtain a hydroxybenzoic acid, said process comprising the step of carrying out the reaction under conditions that a molar ratio of the phenol to the total of the alkali metal compound and the aprotic polar organic solvent is larger than 1. Furthermore, the process may contain the steps of precipitating crystals from the reaction solution, separating the solid from the solution to obtain a wet alkali metal salt of the hydroxybenzoic acid, dissolving the wet alkali metal salt in water, and precipitating crystals from the solution by acidification to obtain the hydroxybenzoic acid.

  • Patent number: 5609552
    Abstract: A method and apparatus for use with an automotive vehicle having an automatic transmission operable with a working fluid. The automatic transmission is coupled to an engine through a torque converter operable in a lockup mode where a mechanical connection is completed between the engine and the automatic transmission in response to a lockup command signal. A degree to which the working fluid is degraded is detected while the torque converter is operating in response to the lockup command signal which is produced when the vehicle speed exceeds a reference value. When the detected degree exceeds a predetermined value, the reference vehicle speed value is increased.
