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 ...

WHILE nitrous acid (we include in this term all material that with water gives nitrous acid) is a negative catalyst in aromatic nitration generally, it has often been found to be a positive catalyst ...
