Patent ID: 8057694

Claim:
A process for producing an agent for deicing and/or anti-icing surfaces or liquids, said process comprising: A) obtaining an industrial stream containing acid component(s), wherein the acid component in said industrial stream consists essentially of compounds selected from the group consisting of glycerol, glycol(s), hydroxycarboxylic acids and mixtures thereof and optionally water; B) modifying said industrial stream by a process comprising at least one of the following steps; i) mixing said industrial stream with at least one of the following, which optionally contains water; a) an additive comprising soluble organic acid salts selected from the group consisting of carboxylic acid salts, hydroxycarboxylic acid salts, dicarboxylic acid salts and mixtures thereof; b) an additive selected from the group consisting of grain stillage, wood stillage, agricultural fermentation products, and milk fermentation products; c) an additive comprising at least one component selected from the group consisting of non-alkyl hydrocarbyl aldosides, alkyl aldosides, monosaccharides, one or more glycol(s), glycerol, ethyl lactate, glycol lactate, ethyl glycinate, ethyl levulinate, ethylene carbonate, glycerin carbonate, pipecolic acid, tetrahydrofurfuryl acetate, tetrahydrofurfuryl tetrahydrofuronate, glucose glutamate, acetals of glycerol, ketals of glycerol, amino acids and salts of amino acids, and sorbitol; d) a deicing and/or anti-icing component comprising soluble chloride salts, thereby producing an improved agent having decreased harmful effects on vegetation and decreased corrosive effects on animals, clothing, roadways and motor vehicles; ii) producing high solubility salts within said industrial stream from in situ acid/alkali reactions employing components of said industrial stream; and C) adding water or removing water during said process to obtain a concentration range from 10 to about 75 weight percent of the acid components based on the weight of acid component and water combined in said agent for deicing and/or anti-icing surfaces or liquids.
