  • Hexitol borate compositions as freeze conditioning agents for particulate solids
    Patent number: 4304798
    Abstract: Hexitol borate salt solutions in combination with polyols effectively reduce the strength of ice crystals formed therefrom to enable solid particles coated therewith to remain substantially free flowing at temperatures as low as -20.degree. C. Treatment of materials such as crushed coal, ore, stone and the like with compositions containing 5-60% by weight sorbitol borate salt and especially sodium sorbitol borate prior to freezing reduces the need for special handling to break up the frozen mass which occurs at temperatures below 0.degree. C. A particularly useful sprayable aqueous solution contains 40-60% by weight sodium sorbitol borate and 20-40% ethylene glycol.
