Abstract
In an improved ice melter comprising an alpha-methyl glucoside and method of making same, an ice melter, as disclosed in U.S. Pat. No. 4,960,531 is further improved in respect to providing improved melting capabilities by providing a substantially uniform coating of alpha methyl glucoside-urea mixture the potassium chloride substrate of a potassium chloride and sodium chloride salt mixture or providing a substantially uniform coating of alpha methyl glucoside-urea mixture to both potassium and sodium chloride salt mixture. The improved invention also includes the method of making the composition which includes the steps for example, of PA1 (1) heating a solution of alpha-methyl glucoside; PA1 (2) adding urea to the heated alpha-methyl glucoside; PA1 (3) heating methyl glucoside and urea mixture; PA1 (4) applying the heated alpha methyl-glucoside and urea mixture to potassium chloride; and PA1 (5) adding sodium chloride to the potassium chloride.
