Methods of forming imines, imine-related and imine-derived compounds using green solvents

The present disclosure relates to using green solvents to synthesize an array of imines, imine-related and imine-derived compounds in an efficient and eco-friendly matter, satisfying green chemistry requirements. Reaction embodiments are performed using solvents, such as ethyl lactate and dimethyl isosorbide, which are both individually characterized as green. In embodiments, solvents include lactic whey and/or water as co-solvents. In these green solvents, the synthesis process discussed herein can produce up to quantitative yields of product at room temperature in a short duration. Embodiments include a method of forming an imine, imine-related or imine-derived compound product. In embodiments, the methods include mixing an aldehyde reactant with a nucleophilic/nitrogen-containing reactant in a green solvent at a temperature between negative twenty degrees Celsius (−20° C.) and positive fifty degrees Celsius (50° C.); stirring the mixture; and forming an imine, imine-related or imine-derived compound product.

Antifreezing coolant composition not including glycol

Disclosed is an antifreezing coolant composition, which does not include glycol but includes environmentally friendly materials, such as a carboxylic acid salt, an anthranilamide compound, a corrosion inhibitor and a triazole compound. The antifreezing coolant composition may form a thin film on the metal surface in cooling systems for vehicles to thereby exhibit high corrosion resistance at low and high temperatures, superior antifreezing performance at low temperatures, and superior cooling performance at high temperatures.
