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.
Claims19
A method of reducing the corrosion caused by a chloride salt, the method comprising the steps of:
- obtaining a molecular weight fraction of a product containing melanoidins, wherein the molecular weight fraction comprises melanoidins having a molecular weight greater than or equal to 12,400;
- forming an aqueous solution including the molecular weight fraction of a product containing melanoidins;
- and
- applying the solution to a metal surface, wherein the molecular weight fraction of a product containing melanoidins reduces corrosion at the metal surface caused by the chloride salt.
An anticorrosive composition comprising:
- water;
- a chloride salt;
- and
- water soluble solids, the water soluble solids comprising a molecular weight fraction of a product containing melanoidins, wherein melanoidins have a molecular weight greater than or equal to 12,400 and comprise at least 1.99% by weight of the water soluble solids.
An anticorrosive composition comprising:
- water;
- a chloride salt;
- and
- water soluble solids, the water soluble solids comprising a molecular weight fraction of a product containing melanoidins, wherein melanoidins have a molecular weight greater than or equal to 10,000 and comprise at least 10% by weight of the water soluble solids.
