Abstract: A novel chloride salt based de-icing composition comprising a corrosion inhibitor of a de-sugared sugar beet molasses. The corrosion inhibited de-icing compound comprises from 5 to 25 percent by weight of de-sugared molasses compared with the weight percent of the chloride salt in the de-icing composition.

Abstract: Novel magnesium hydroxide having a fine, plate-like crystalline structure, a median particle size of up to about 1 micron and a particle size distribution in which about 90% of said magnesium hydroxide particles are less than about 3.5 microns is prepared by a flash precipitation process in which less than or greater than an equivalent amount of alkaline material is reacted with a magnesium salt in a concentrated aqueous mixture thereof. Ultrasonic mixing means is used to combine heated aqueous streams of an alkaline material and a magnesium containing solution followed by a post heat treatment. The magnesium hydroxide is especially useful in providing flame retardancy in admixture with thermoplastic resins.
