摘要： Finely divided lime, at any degree of slaking, is introduced in a steady stream into an agitated reactor designed to produce pellets or aggregates. Concentrated acetic acid is simultaneously introduced in a steady stream at a rate equal to the chemical combining rate required to produce calcium magesium acetate. Water content of the reaction stream is critical; the mol ratio of water, including water of neutralization, to the calcium magnesium acetate product must fall in the range 3.3-7.0 in order to form the desired pellets and to avoid sticking, caking, and dust emanation from the reactor. Product pellets are drawn off in a stream from the reactor and dried for use as a non-polluting roadway and walkway deicer. Traction agent is optionally incorporated into the deicer pellets by introducing a steady stream of traction agent to the reactor simultaneous with raw materials introduction. Magnesium-to-calcium ratios greater than one are achieved by blending dolime with magnesium-rich ore.

摘要： Finely divided ore blends containing chemically active magnesium oxide and calcium oxide are physically combined with a critical amount of water prior to reaction with acetic acid. Intermediate products range in physical consistency from putty-like masses to viscous liquors, depending upon the relative fraction of magnesium oxide in the ore feed. Intermediate products freeze to form hydrates of magnesium calcium acetate, the freeze times being dependent upon a number of chemical and physical parameters. Product drying requirements range from minimal drying to none at all, depending upon the magnesium fraction in the products. Products are non-friable and have excellent crush strength, and are suitable for storage, shipping and application in chemical deicing as well as other end use applications where crude low-cost materials are called for.A unique situation centers around the composition corresponding to the magnesium mol fraction of 0.8. This material requires no drying and exhibits an extraordinary high crush strength. Additionally, as much as 75% by weight of traction agent (sand) can be successfully incorporated into this material without the aid of chemical binders.

摘要： Several novel means are presented of chemically combining calcium/magnesium acetate with calcium chloride to form a series of calcium magnesium acetate-chloride triple-salts. The low-cost processes are carried out using minimal proportions of water, and no co-products or by-products are formed. Products are optionally pelletized for use as roadway deicing agents. By adjusting the relative amount of chloride input, products can be tailored to adequately perform a given deicing or freezing-point depression task with a minimum of environmental pollution by chloride.All product variations are non-deliquescent.In the preferred embodiment, lime is reacted with concentrated acetic acid to form calcium/magnesium acetate. To the acetate is added an aqueous calcium chloride solution. The concentration of water in the reaction batch is critical to the attainment of complete chemical combination to form a flowable solid product.

摘要： A reduced pollutant-containing salt mixture and method of making same is provided wherein a salt mixture partially comprised of calcium acetate and partially comprised of at least one other pollutant salt is produced by mixing a pollutant salt-containing solution and a calcium acetate-containing solution and converting said mixture into a solid salt containing both the pollutant salt and the nonpollutant calcium acetate. A process option involves chemically reacting calcium chloride and calcium acetate in a calcium chloride-to-calcium acetate mole ratio in the range from 0 to 1 to produce a non-deliquescent salt. A further process option includes mixing either dry calcium chloride or dry sodium chloride with dry calcium acetate to obtain a reduced pollutant-containing salt mixture.

摘要： A process for the manufacture of calcium acetate pellets suitable for surface deicing, which comprises slow addition of water to dried calcium acetate or to calcium acetate freshly prepared from reaction of hydrated or unslaked lime with concentrated acetic acid, in an agitated vessel designed to produce pellets. Pellets are dried to a critical residual water level to avoid their embrittlement. The relative amount of water used in the pelletizing process is highly critical, and depends upon the source of calcium acetate as well as the amount of magnesium ion in the pellet formulation.

摘要： A process of reacting aqueous acetic acid and crushed raw limestone in such a way as to produce a mixture of calcium acetate, calcium acid-acetate, and unreacted raw limestone devoid of undesirable fine limestone. Such a product is useful in winter highway treatment, where the environmentally safe soluble acetates function to depress the freezing point of water, and the limestone acts as a roadway traction agent. When as much as 3 mols of acetic acid per mol of active calcium carbonate in limestone are used, all the limestone is consumed, with virtually 100% yield of calcium acid-acetate.
