Organic Synthesis Catalyst Iron Chloride Hexahydrate CAS 10025-77-1 Solid Powder

Ferric Chloride Hexahydrate

The main differences between solid powder and liquid of hexahydrate ferric chloride

1. Physical form and composition

Solid powder: appearing as yellow brown crystals or blocks, easily deliquescent into a reddish brown liquid (requires sealed storage).

Liquid: It is a brown transparent solution, usually in the direct form of hexahydrate ferric chloride dissolved in water, and can be used without a dissolution step.

2. Production process and raw materials

Characteristic Solid Powder Liquid

The production process involves the reaction of hydrochloric acid with iron to produce a solution, which is then evaporated and crystallized to form hexahydrate crystals. These crystals can be directly prepared into the solution or dissolved in a solid, eliminating the need for crystallization steps and resulting in lower costs

Raw material control requires controlling moisture and temperature to form stable crystals. The main raw materials are water and high-purity ferric chloride to avoid impurities affecting solution stability

3. Transportation and Storage

Solid powder: requires moisture-proof sealed packaging (such as woven bags, iron drums), with high transportation costs and the need to avoid high temperature environments.

Liquid: Transported in plastic drums or tanks, due to its high moisture content and large volume, the transportation cost increases, but the storage safety is better than that of solids (reducing the risk of dust leakage).

4. Convenience of use and application scenarios

Solid powder: It needs to be dissolved before use. The dissolution process easily generates heat, and the operation is complex but the storage stability is high. It is suitable for remote areas or scenarios that require long-term stocking.

Liquid: No need to dissolve, add directly, saving operation time; Suitable for large-scale water treatment sites (such as sewage treatment plants) and chemical synthesis that requires rapid reactions.

5. Economic comparison

Cost: The unit price of liquid ferric chloride is usually more than 40% lower than that of solid (with the same concentration of active ingredients), but transportation costs may offset some cost advantages due to increased volume and weight.

Sludge treatment: After both treatments, the amount of sludge is relatively small, but the liquid can be more accurately controlled by adjusting the concentration, further reducing costs.

6. Performance Performance

Parameters Solid Powder Liquid

At the same concentration of flocculation efficiency, it is equivalent to a liquid and needs to be fully dissolved. Directly adding it can disperse faster and reduce the phenomenon of alum splashing

Applicable range: Suitable for pH 4-12, suitable for complex water quality of 47 and solid, but more convenient for adjusting the dosage concentration

Summary

The core differences between solid powder and liquid hexahydrate ferric chloride are reflected in their morphology, production process, transportation and storage, and ease of operation

Solid: suitable for long-distance transportation and long-term storage, but requires dissolution operation;

Liquid: Strong ready to use, suitable for high-frequency and large-scale scenarios, with significant cost advantages
