1. Process route

The continuous chlorination method uses acetic acid and liquid chlorine as raw materials, acetic anhydride and sulfuric acid as catalysts, and obtains chloroacetic acid through processes such as acetic acid chlorination, hydrogenation, distillation, and slicing.

2. Process flow

Chlorination process → Hydrogenation reduction process → Distillation process → Tail gas absorption process → Alkali washing and neutralization process → Slicing and packaging process → Public works process

3. Technical advantages

The chloroacetic acid process package of Shandong Catech Technology Co., Ltd. is independently developed and adopts the acetic anhydride catalytic chlorination continuous process, which can obtain products with higher purity and save energy. In recent years, we have successively completed multiple sets of continuous chloroacetic acid production plants in China, with rich experience in chloroacetic acid plant design and start-up guidance, and have won praise from industry customers.

4. Downstream direction

Measure zinc, calcium, silicon, and titanium. Synthesize caffeine, adrenaline, aminoacetic acid, and naphthylacetic acid. Manufacturing various dyes. Rust remover. Used for pesticide production and as an intermediate in organic synthesis. Used as an acidifier for starch adhesives. It is also an intermediate in dyes, pharmaceuticals, pesticides, synthetic resins, and other organic synthetic materials. Used in the dye industry to produce indigo dyes. Chloroacetic acid is also an important carboxymethylating agent used in the preparation of sodium carboxymethyl cellulose, ethylenediaminetetraacetic acid, etc. It is also used as a flotation agent for non-ferrous metals and a chromatographic analysis reagent.
