Anticorrosive composition

Abstract

The present invention relates to the discovery that melanoidins, and higher molecular weight fractions of products containing melanoidins, provide significant corrosive inhibition, which render these melanoidins suitable for use as anticorrosive agents in corrosive environments. In addition to being highly anticorrosive, the melanoidins of the present invention are environmentally friendly and non-toxic, and can be found in animal food and in human foodstuffs.

Problems solved by technology

Corrosion problems caused by exposure to and / or the use of chloride salt has been a longstanding problem in many applications and industries, including deicing and anti-icing for roadways and bridges (often causing rebar corrosion), oil well drilling operations, and other industrial and marine applications carried out in corrosive environments.

These various additives can be expensive.

To a large extent, these additives have been ineffective in controlling the corrosivity of the brines.

Similarly, the use of deicing formulations, which commonly include a chloride salt, inherently have a corrosive effect upon roadways, bridges (including rebar corrosion) and the environment.

However, when corrosion is an issue that must be addressed, a separate corrosion inhibitor component is usually added to the carbohydrates.

The main reason for this approach is that excessive amounts of the carbohydrate would be required in order to obtain a significant anticorrosive effect due to the relatively small amount of anticorrosive moiety contained in a given carbohydrate.

In fact, excessive concentrations of carbohydrate to accomplish a significant reduction in corrosion could well render the carbohydrate unsuitable for its intended use (e.g., as an effective deicer).
