Dicyclohexylamine, commonly abbreviated as DCHA (CAS 101-83-7), is a strongly basic secondary amine. It appears as a colorless to slightly yellowish liquid with a characteristic faint fishy or amine-like odor. Dicyclohexylamine (CAS 101-83-7) is an important chemical intermediate widely utilized in the production of corrosion inhibitors, rubber accelerators, and various specialty chemicals. Due to its unique alicyclic structure and strong alkalinity, DCHA is highly effective in neutralizing acidic components and forming stable salts in complex industrial formulations.

Corrosion Inhibitor and Metal Protection

This product is primarily utilized as an effective corrosion inhibitor in steam boiler systems, metalworking fluids, and anti-rust papers to protect ferrous metals from oxidation.

Rubber Vulcanization Accelerator Intermediate

It serves as a critical raw material for the synthesis of sulfenamide-type accelerators, which are essential in the tire and rubber industry for controlling the curing process.

Pesticide and Pharmaceutical Intermediate

DCHA is used as a building block in the production of herbicides and certain pharmaceutical compounds, often acting as a neutralizing agent or a reactive intermediate.

Textile Dyeing Auxiliary

In the textile industry, it is applied as a pH regulator and auxiliary agent to improve dye penetration and color fastness in synthetic fibers.

Standard industrial packaging options for Dicyclohexylamine include:

• 180kg or 200kg tight-head steel drums (Standard export packaging).

• 1000kg IBC tanks for streamlined bulk handling in manufacturing plants.

• ISO Tanks for large-volume international maritime transport (approx. 20-22 MT).

• Small-volume sample bottles available for laboratory and research evaluation.

Dicyclohexylamine should be stored in a cool, dry, and well-ventilated warehouse. It is sensitive to air and moisture, which can cause discoloration; therefore, containers must be kept tightly sealed and nitrogen-blanketed if possible. Keep away from heat, sparks, and open flames. It should be stored separately from strong acids and oxidizing agents to prevent hazardous chemical reactions.

Corrosion Inhibitor and Metal Protection

• Q1: How does Dicyclohexylamine function as a vapor-phase corrosion inhibitor (VCI)?

  A1: It has a relatively high vapor pressure, allowing it to evaporate and form a protective molecular film on metal surfaces, neutralizing acidic moisture in the air.

• Q2: Is DCHA suitable for copper or aluminum protection?

  A2: It is primarily designed for ferrous metals (iron and steel); for non-ferrous metals, specific additives are usually combined with DCHA to prevent potential staining.

• Q3: Can DCHA be used in closed-loop water systems?

  A3: Yes, it is an excellent pH booster and corrosion inhibitor for closed cooling and heating loops to prevent pipe pitting.

Rubber Vulcanization Accelerator Intermediate

• Q1: What type of accelerators are made from DCHA?

  A1: It is most commonly used to produce dicyclohexyl-2-benzothiazole sulfenamide (DCBS), a delayed-action accelerator favored in radial tire production.

• Q2: Does DCHA improve the storage stability of rubber compounds?

  A2: By serving as a precursor to delayed-action accelerators, it helps prevent "scorch" (premature vulcanization) during processing and storage.

• Q3: What is the benefit of DCBS over other sulfenamides?

  A3: It provides the longest scorch safety and excellent adhesion to steel cords, making it superior for heavy-duty industrial tires.
