Abstract

PROBLEM TO BE SOLVED: To provide a deicer composition which causes little corrosion of structures such as roads, etc., and vehicles, gives little damage on the environment and exerts an excellent deicing effect, and its preparation process. SOLUTION: The deicer composition containing a double salt comprising an acetate, a carbonate and a formate does not cause corrosion nor environmental damage. The deicer composition is prepared either by neutralizing a base and the corresponding organic acid and subsequently drying and grinding the obtained organic salt (double salt), or by physically grinding and mixing each organic salt to yield a powdery double salt, granulating this using a binder and drying and processing this into a desired particle size.

For smooth traffic flow, snow or ice on the road surface must be treated quickly and effectively.For this reason, calcium chloride is used as a melting agent in South Korea and sodium chloride as in the United States and Japan. Mainly used. These chloride-based ice melting agents are inexpensive and have excellent ice melting ability, but contain chloride ions that promote corrosion of metals. As a result, sustained use of chloride-based deicing agents promotes corrosion of bridges and road structures and shortens their life, resulting in significant cost losses. Further, the chloride-based ice melting agent also has an adverse effect on the surrounding environment, and may cause yellowing or death of plant leaves.

が非常に大きいため生分解性がよくない。At present, non-chloride ice melting agents such as urea and propylene glycol are used for special situations such as airplanes and airport runways. Although urea is less corrosive, it can effectively melt ice only at -4 ° C or higher, and has a low freezing point lowering capacity per unit weight. When doing so, it causes yellowing of the leaves of the plant. Propylene glycol is non-corrosive and low toxic, but has lubricity to reduce slip resistance and biochemical oxygen demand (BOD)
Is so large that biodegradability is not good.

系融氷剤を開発する方法の二つに大別される。Therefore, an alternative melting agent which has good biodegradability even at a relatively low temperature, has low corrosiveness, has no adverse effect on concrete and the environment, and has an ice melting ability equal to or better than that of chloride-based ones. It is desired to develop. Alternative ice melting agents are developed by adding a rust inhibitor to prevent corrosion to chloride ice melting agents such as calcium chloride and sodium chloride, and by using non-chloride ice melting agents that do not contain chloride ions. Can be broadly divided into two methods.

As shown in U.S. Pat.No. 4,613,450, U.S. Pat.No. 5,553,931 and U.S. Pat.No. 5,595,679, a small amount of an amine phosphate, a fluorine phosphate, a rare earth metal salt, an alkali metal silicate or These mixtures are added for use. It is said that the rust preventive effect of such a melting agent containing a rust preventive depends on the content of the rust preventive, the temperature and the amount of oxygen. Moreover, many problems have been pointed out with respect to the rust prevention effect. That is, there is a report that the rust preventive reacts with concrete and is fixed, and cannot penetrate into the concrete, so that it does not play a role in preventing corrosion of reinforcing steel. It has also been reported that even if it has a rust preventive effect, it is inferior to non-chloride organic acid salts.

There are acetates such as potassium acetate and sodium formate. CMA was developed intensively in the United States,
Although it has the advantage of being environmentally friendly and having low corrosiveness, it has a problem that it is hydrolyzed and generates acetic acid vapor which is harmful to the human body even when the density is low and the pH is 9 or more. However, the melting point is lower than that of sodium chloride as well as calcium chloride, and the price is expensive.

It can represent a number of disadvantages, such as the occurrence of phenomena. Such CMA is made from acetic acid and dolomite (U.S. Pat. No. 4,643,467), but due to the high cost of acetic acid, U.S. Pat.
There has been an ongoing effort to obtain acetic acid as a raw material from cheese whey and biomass through fermentation and reaction with alkali under high temperature and pressure as disclosed in 97/40119.

されている。However, since the organic acids produced by such a method include not only acetic acid but also various organic acids having a higher molecular weight, there is a problem that the melting ability of the ice melting agent is reduced as a result. . Potassium acetate, like CMA, has disadvantages such as low density and flour, which is hydrolyzed to produce acetic acid. However, since its eutectic point is extremely low, it is effective even at a low temperature of about -26 ° C. , Mainly used in liquid form.

Sodium formate is a promising alternative ice melting agent that has less powder flying problem like CMA, has low corrosiveness and does not induce concrete rupture. However, this also has the disadvantage that, similarly to sodium chloride, it absorbs heat upon melting, has a lower melting ability than sodium chloride, and is much more expensive than sodium chloride.
