Abstract:

The object of this study was to develop a one package, single phase inhibited antifreeze which could be packaged and stored for periods up to two years without deterioration of the antifreeze or corrosion of the container. Ethylene glycol type antifreeze and several inhibitor combinations that were known to impart good corrosion protection characteristics to automotive cooling systems were screened by glassware bench corrosion tests. The more promising compounds were subjected to simulated service tests. The antifreeze compound having the best corrosion protection properties was selected for packaging storage tests in clear and blue polyethylene bottles and clear polyethylene five gallon containers with a cardboard overpack. All bottles were exposed to natural daylight. Some of the five gallon containers had parts of four sides cut away so there was direct exposure of the contents to natural daylight. These storage showed that the inhibitor system was stable in the blue bottles and in the overpacked five gallon containers. In the clear bottles and the cut away five gallon containers light initiated the oxidation of mercaptobenzothiazole to benzothiazyl disulfide. Author, modified-PL
