No. 14/360,163, filed, May 22, 2014 and entitled “ENVIRONMENTALLY-FRIENDLY IMPROVED DEICER COMPOSITIONS”, which is a '371 of PCT Patent Application Serial No. PCT/US2012/067957, filed Dec. 5, 2012, and entitled “ENVIRONMENTALLY-FRIENDLY IMPROVED DEICER COMPOSITIONS”, which claims priority to U.S. Provisional Application Ser. No. 61/576,545, filed Dec. 16, 2011 and entitled “ENVIRONMENTALLY-FRIENDLY IMPROVED DEICER COMPOSITIONS”, which applications are hereby incorporated by reference herein in their entirety.

FIELD

The present application relates generally to environmentally-friendly deicing compositions with reduced corrosiveness that provide a reduced biochemical oxygen demand, comprising a liquid deicing agent and additives that provide reduced corrosiveness. Aspects of the disclosure are particularly directed to the use of the composition as a deicer, an anti-icer, or a pre-wetting agent.

BACKGROUND

This application relates to deicer compositions with a reduced environmental impact. More particularly, the application relates to deicer compositions with reduced corrosiveness and biochemical oxygen demand that can be used as a liquid deicer, a pre-wetting agent when mixed with a deicing salt to form a pre-wetted deicer, or an anti-icer.
There is an ever present challenge to develop deicer formulations which are more effective and at the same time have a reduced impact on both the natural environment and infrastructure. In particular, there is a strong desire to find deicer compositions that have reduced biochemical oxygen demand (BOD) on water systems. Varieties of additives for deicers are currently used but have limitations. For instance, inorganic compounds such as phosphate and chromate based corrosion inhibitors are used. However, these compounds have undesirable environmental impact. Hexavalent chromium compounds are genotoxic carcinogens. Phosphates can contribute to eutrophication of lakes and streams. Others have developed deciers that have used organic compounds as additives. Examples include desugared beet molasses (U.S. Pat. No. 7,473,379), honey (U.S. Pat. No. 6,616,739), low molecular weight carbohydrates (U.S. Pat. No. 6,299,793), and molasses (U.S. Pat. No. 6,596,188). However, organic additives are not without their own potential for detrimental environmental impact. In particular, the types of organic additives commonly used in deicers are usually readily biodegradable, resulting in the potential for increased biochemical oxygen demand (BOD) when these additives get into natural waters. Increased BOD can impair the living ecosystem in natural waters, resulting in death of fish and other aquatic organisms if BOD is sufficiently high. Thus, it is desirable to identify additive systems for deicers that have reduced BOD.
Deicer compositions can include a liquid deicing agent combined with at least one corrosion inhibiting additive and at least one viscosifying additive. The deicing composition can be used in a variety of ways, including alone as an anti-icer or deicer, or as a pre-wetting agent to combine with a solid deicing agent to form a pre-wetted deicer. When used as anti-icers they are applied directly to a surface prior to a snow storm or ice event. They serve to interrupt the boundary layer of snow between the surface and the accumulated snow pack, thereby preventing the snow from bonding to the surface and facilitating its removal by snow plows. The deicer composition can also be used as a deicer to melt snow or ice that has already accumulated on a surface. The deicer composition can also be used as a pre-wetting agent having a liquid deicing agent either alone or with additives that are added to or blended with a solid deicing agent to yield a pre-wetted deicer. The solid deicing agent can include compounds such as urea or a sodium, potassium, magnesium, calcium or ammonium salt of chloride, carbonate, lactate, succinate, acetate, propionate, formate, or combinations thereof. Examples include, but are not limited to, sodium chloride, magnesium chloride, calcium chloride, potassium chloride, potassium carbonate, urea, sodium acetate, potassium acetate, ammonium acetate, calcium magnesium acetate, sodium formate, potassium formate, potassium lactate, sodium lactate, sodium succinate, potassium succinate or combinations thereof. The pre-wetting agent can be sprayed onto the solid deicing agent or preferably it is pre-blended with the solid deicing agent. This allows those applying the deicer compositions to the road to use the same standard equipment and trucks that used when applying dry salts to the road.
The present invention allows for a reduced environmental impact while still providing an effective deicer composition. Surprisingly, it has been found that certain combinations of additives can provide effective corrosion inhibition at reduced BOD levels, such as when utilizing a corrosion inhibiting additive such as gluconate with a viscosifying additive such as xanthan gum in chloride deicers, which provides corrosion protection at even lower BOD levels than is possible with either additive by itself or compared to other additives.

SUMMARY

The present disclosure relates to a deicer composition comprising a liquid deicing agent and additives to inhibit corrosion. The deicer composition can include a combination of additives, such as a viscosifying additive such as xanthan gum and a corrosion inhibiting additive such as sodium gluconate, together with a liquid deicing agent comprising an aqueous solution of a deicing salt including a chloride salt such as sodium chloride, potassium chloride, magnesium chloride, calcium chloride, or combinations thereof, or the liquid deicing agent can be liquid bittern. Other performance enhancers can be added to the deicer composition, such as radiation absorbers. The deicer combination can be used as an anti-icer which can be applied before a snow or ice event, a deicer which can be applied during or after a snow or ice event, or can be used as a pre-wetting agent applied to a solid deicing agent to form a pre-wetted deicer.
One embodiment is directed toward a deicer composition comprising a liquid deicing agent, a corrosion inhibiting additive, and a viscosifying additive, where the liquid deicing agent comprises an aqueous solution of a deicing salt, where the corrosion inhibiting additive comprises gluconic acid, saccharic acid, gluconate salts, saccharate salts or combinations thereof, and the viscosifying agent comprises xanthan gum, cellulose gum, polyvinyl pyrrolidone, acrylic acid polymers, cross linked acrylic polymers, polyether polyols, sodium carboxymethyl cellulose, hydroxyethyl cellulose, carboxymethyl hydroxypropyl guar, hydroxypropyl guar, polyanionic cellulose, pregelatinized crosslinked starch such as hydroxypropyl distarch phosphate and distarch phosphate, scleroglucan, pectin or combinations thereof. In one embodiment, deicing salts can include sodium chloride, magnesium chloride, calcium chloride, potassium chloride, or combinations of these salts. The liquid deicing agent can also be comprised of liquid bittern, which is a product derived from sea salt production, and is the liquid remaining after sodium chloride is removed from the sea water. In one embodiment, the corrosion inhibiting additive is sodium gluconate and the viscosifying additive is xanthan gum.
The deicer composition can further comprise a solid deicing agent, such as sodium chloride, magnesium chloride, magnesium chloride hydrate, calcium chloride, calcium chloride hydrate, potassium chloride, urea, potassium acetate, sodium acetate, calcium magnesium acetate, sodium formate, potassium formate, or combinations thereof. As used herein, the terms “magnesium chloride hydrate” and “calcium chloride hydrate” refer to solid hydrated magnesium chloride and calcium chloride, respectively. The amount of hydration can vary from monohydrate to hexahydrate or higher. In this embodiment, the liquid deicing agent and additives form a pre-wetting agent that is mixed with the solid deicing agent to form a pre-wetted deicer. The most common solid deicing agent is sodium chloride, which is often mined as rock salt. In another embodiment, the deicer composition further comprises a radiation absorber.

EXAMPLES

Aspects of certain methods in accordance with aspects of the invention are illustrated in the following examples.

Example 1

Corrosion tests were run according to the following procedure: the test coupons used are ASTM F 436, Type 1 flat steel washers with approximate dimensions 1.38 in. outer diameter, 0.56 in. inner diameter, and 0.11 in. thick with a density of approximately 7.85 grams per cubic centimeter and a Rockwell Hardness of C 38-45. Coupons are wiped with hexane to remove grease and oil and then acetone rinsed. The coupons are removed from the acetone, allowed to air dry and then weighed to the nearest 0.1 mg.
The liquid deicer formulations are diluted 50/50 with deionized water, and approximately 360 grams of each diluted deicer solution is put into a 500 milliliter Erlenmeyer flask. Each flask is equipped with a rubber stopper that has been drilled to allow a line to run through it. Three coupons are mounted in a plastic holder that is suspended inside the flask through the stopper hole. A timed device raises and lowers the test coupons so that they are completely immersed in the test solutions for 10 minutes and then raised so they are suspended within the flask and above the test solution for 50 minutes. This cycle is repeated for 68-72 hours, depending on the test. Tests are conducted at room temperature. At the end of the exposure period the coupons are removed from the test solutions and scrubbed with a nylon brush under running water to remove coarse corrosion products. They are then immersed in a cleaning solution of approximately 3.8% hydrochloric acid and 0.1% Rodine 213 in warm tap water for approximately 20 minutes. The coupons are then removed, scrubbed again with a nylon brush under running water, immersed in an acetone bath and allowed to air dry. The coupons are then re-weighed to the nearest 0.1 mg. Fresh coupons that have not been exposed to the test solutions are also taken through the same cleaning procedure to determine the weight loss due to the cleaning process. The weight loss due to cleaning is subtracted from the total weight loss of the test coupons to determine the actual corrosion weight loss. A corrosion rate in mils per year is calculated from the measured coupon weight loss using the formula: mils per year=(weight loss of coupons in milligrams×534)/(coupon area in square cm×test exposure time in hours×density of coupons).

TABLE 1

Corrosion Rates and BOD of Deicer Compositions on Mild Steel

		% Na		Corrosion Rate
% MgCl₂	% Xanthan Gum	Gluconate	BOD (ppm)	(mils per year)

26.0	0	0	0	12.9
26.0	0	0.6	3,042	6.2
26.0	0.6	0.15	1,961	5.6
26.0	0.6	0	1,200	8.1

BOD values in Table 1 are calculated assuming a BOD of 507,000 ppm for sodium gluconate and a BOD of 200,000 ppm for xanthan gum. The data in Table 1 show that combining xanthan gum and sodium gluconate makes it possible to achieve corrosion inhibition levels at lower BOD levels than by using sodium gluconate as the lone corrosion inhibiting additive. Similarly, only using an additive such as xanthan gum does not provide sufficient corrosion protection. Surprisingly, by using sodium gluconate and xanthan gum together in a liquid magnesium chloride deicer it is possible to maximize corrosion inhibition and at the same time minimize the BOD impact on waterways. This combination of a corrosion inhibiting additive and a viscosifying additive provides corrosion protection for deicer handling equipment while at the same time providing a reduced environmental impact on waterways, aquatic ecosystems and aquatic organisms by reducing the impact from BOD.
The particular embodiments disclosed above are illustrative only, as the present disclosure can be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. Furthermore, no limitations are intended to the details of construction or design herein shown, other than as described in the claims below. It is therefore evident that the particular embodiments disclosed above can be altered or modified and all such variations are considered within the scope and spirit of the present disclosure.
