Embodiment

[0091] For deicing compositions for use on airport runways and other surfaces requiring deicing, the desirable properties of the compositions are well known. The properties include good ice melting performance, low impact on structural components including aircraft alloys, steel and concrete, and low BOD to minimize environmental impact. The data presented above clearly show that succinate-based deicer formulations can significantly reduce the impact on structural components such as aircraft alloys, steel and concrete and on the environment.

[0092]The freezing point of a deicer solution is the primary indicator of deicer performance. It is also an important characteristic of heat transfer fluids since they are often formulated for use in cold regions. Freezing point can be determined at 50% and 25%. In the runway deicer industry, due to dilution of the deicer upon application and for ease of measurement, it is measured at 25%, ie a 50% commercial solution is diluted to 25%...

Abstract

A composition for deicing or for the preparation of a heat transfer fluid is provided. The composition comprises a mixture of at least two carboxylic acid salts having a t / c ratio of 2 or lower, including a dicarboxylic salt and a monocarboxylic salt, said dicarboxylic salt being present in the mixture in an amount of at least 50 wt % of the weight of the mixture, on a dry basis. More particularly, said mixture is including a succinate and a formate, wherein the succinate is in an amount of at least 50 wt%, on a dry basis. Also provided is a method for deicing a surface or preventing the accumulation of ice, snow or a mixture thereof on a surface, comprising a step of applying on a surface covered by ice, snow or a mixture thereof, or susceptible of being covered by ice, snow or a mixture thereof, the above composition. The composition is also useful for the preparation of a heat transfer fluid coolant to be used in a heat transfer system comprising a heat transfer fluid provided with a cooling system.

Description

technical field [0001] The present invention relates to compositions and methods of using said compositions in various applications such as residential and commercial deicing applications or in the preparation of heat transfer fluids. The invention also relates to the use of the heat transfer fluid thus obtained. Optionally, the invention is also characterized in that the composition is obtainable at least in part from a carboxylate-containing fermentation broth. Background technique [0002] Chemical deicing is used daily in winter to maintain safer conditions on sidewalks, roads, highways and airports. Numerous materials and compositions currently exist for such deicing applications. But the materials currently in use suffer from a number of drawbacks, including their corrosiveness and their impact on the environment. [0003] Acetates and formates such as potassium salts are currently used in airport runway deicing applications 1，2 . However, there is evidence that e...
