Abstract
The present invention provides deicing compositions which are environmentally benign, a process for producing the composition from certain waste process streams, and the methods of deicing and/or anti-icing.
Claims34
A method of preparing a substantially environmentally benign deicing composition, said method comprising:
- (a) recovering an industrial waste stream comprising a hydroxycarboxylic acid;
- and
- (b) alcoholizing at least a portion of hydroxycarboxylic acids in said recovered waste stream with an alkyl alcohol to convert said portion of hydroxycarboxylic acids to water soluble hydroxycarboxylic acid esters.
A deicing composition comprising a water soluble hydroxycarboxylic acid ester.
A method of preparing a substantially benign deicing composition, said method comprising:
- (a) recovering an industrial waste stream comprising a water soluble hydroxycarboxylic acid;
- and
- (b) adding an effective amount of a freezing point lowering compound to said industrial waste stream, said freezing point lowering compound selected from the group consisting of water soluble hydroxycarboxylic acid esters, glycosides and mixtures thereof.
A method of preparing a substantially environmentally benign deicing composition, said method comprising:
- (a) recovering an industrial waste stream comprising a sugar compound;
- and
- (b) alcoholizing at least a portion of the sugar compound in said recovered waste stream with an alkyl alcohol to convert said portion of sugar compound to alkyl glucosides.
A method of preparing a substantially environmentally benign deicing composition, said method comprising:
- (a) recovering an industrial waste stream comprising a water soluble hydroxycarboxylic acid;
- and
- (b) reacting at least a portion of said water soluble hydroxycarboxylic acid to form anionic hydroxycarboxylic acid salts.
A method for deicing and/or anti-icing a surface, said method comprising:
- applying to said surface a composition comprising:
- (a) a deicing and/or anti-icing agent comprising at least about 15 weight percent of a hydrocarbyl aldoside and
- (b) water.
A de-icing and/or anti-icing agent composition comprising:
- (a) a hydroxycarboxylic acid salt,
- (b) a hydrocarbyl aldoside and
- (c) water.
A de-icing and/or anti-icing agent composition comprising:
- (a) a hydrocarbyl aldoside,
- (b) a hydroxycarboxylic acid ester, and
- (c) water.
