Abstract: Disclosed is an improvement in a process for production of cyclohexane by liquid phase hydrogenation of benzene wherein no diluent is necessary, which comprises contacting benzene and hydrogen in the presence of a mixed catalyst bed comprising a first catalyst which is a less active hydrogenation catalyst selected from elements of Group VIII of the Periodic Table and a second, more active catalyst, comprising a Group VIII metal supported on an oxide, such as, for example, alumina, silica or titania at a temperature of about 40.degree. C. to about 300.degree. C. and pressure sufficient to keep the benzene liquid at the chosen reaction temperature.

Abstract: A corrosion-inhibited antifreeze composition is disclosed. Specifically, the antifreeze composition comprises a major portion of a liquid alcohol freezing point depressant and a minor portion of at least one hydroxyl-substituted aromatic carboxylic acid having the hydroxyl radical disposed proximate to the carboxylic radical. The above described acid is employed as a corrosion inhibitor. Other conventional corrosion inhibitors may be employed in conjunction with the acids.In another embodiment, the present invention relates to a process for inhibitig the corrosion of metals present in the cooling system of an internal combustion engine which comprises intimately contacting the metal surface to be inhibited against corrosion with the antifreeze composition described above. Most preferably, the target substrate is high lead solder.
