IN order to check the constitution of preparations of the three different tritium toluenes carrying radiochemical amounts of tritium in the aromatic nucleus, samples were transformed into ...

IT was known fifty years ago that hydroxy byproducts arise in small quantities in the nitration of benzene and toluene, and their significance was discussed by Armstrong and Rossiter in 1891. Since ...

Air, pressure, heat, corrosive agents, and other factors encountered by a lubricant during use can cause chemical changes in the oil. Changes in the oil chemistry can have a negative impact on the ...

Chemists have yet another use for fluorine, as a through-space activator for electrophilic aromatic substitutions. Thomas Lectka and coworkers at Johns Hopkins University used a Diels-Alder reaction ...

An in-service lubricant encounters heat, air, corrosive agents, pressure, and other factors that cause chemical changes in the oil. Changes in oil chemistry can also impact the lubricant’s ability to ...
