Industrial grade Copper (II) Chloride Dihydrate purity can reach over 98.0%, electronic grade product purity ≥ 99.9%, metal impurity content < 50 ppm, anionic impurity < 100 ppm, which can avoid the interference of impurities on the quality of electroplating layer and the selectivity of catalytic reaction, and ensure the consistency of end product performance.
This compound dissolves quickly, completely dissolving in room temperature water within 2 minutes, with uniform and stable dissolution and no violent exothermic reaction during the dissolution process.
It can be used as a catalyst, oxidant and other functions to meet the needs of different industries.
Copper (II) Chloride Dihydrate is the core salt in acidic copper chloride electroplating processes. It is used to prepare copper plating layers for electronic components, hardware accessories, and automotive parts. It is widely used in through-hole electroplating of PCBs and connector terminal electroplating, improving the corrosion resistance of the plating layer by more than 30% to meet the long-term use requirements of electronic equipment.
As a highly efficient catalyst, Cl₂CuH₂O is used for the chlorination reaction of aromatic compounds (such as the preparation of 2-chlorotoluene and p-chlorobenzaldehyde). The catalytic efficiency is 25%-35% higher than that of traditional catalysts, the yield of target products can reach more than 88%, and the by-product formation rate can be reduced.
Electronic-grade Copper (II) Chloride Dihydrate is used to prepare copper-based conductive pastes. Its low impurity characteristics ensure that the resistivity of the conductive paste is <1.5×10⁻⁶ Ω・cm. In the preparation of nanomaterials, it is used as a copper source to prepare copper oxide nanoparticles and copper-based MOF materials through hydrothermal synthesis, which are applied in the fields of sensors and supercapacitors.
Copper (II) Chloride Dihydrate is hygroscopic and must be sealed in double-layer packaging (inner polyethylene vacuum bag + outer corrosion-resistant plastic drum). Store in a dry and ventilated warehouse below 25°C and relative humidity <55%, away from water sources, humid environments and alkaline substances (such as sodium hydroxide and ammonia), and avoid direct sunlight.
It is strictly forbidden to store or transport this product with strong alkalis, active metals, reducing agents, or flammable organic substances. Otherwise, chemical reactions may occur (such as displacement reactions that produce copper or neutralisation reactions that release heat), leading to container damage or safety hazards. Also, avoid storing this product in the same warehouse as food, feed, or pharmaceutical products to prevent contamination.
Ingestion can irritate the gastrointestinal mucosa, causing symptoms such as nausea, vomiting, abdominal pain, and diarrhoea. Excessive intake of Cu²+ may also damage liver function. Do not induce vomiting (to avoid corroding the oesophagus). Immediately drink plenty of milk or egg whites (to absorb copper ions) and quickly take the patient to the hospital for gastric lavage and symptomatic treatment.
Containers and tools that come into contact with the product must be made of corrosion-resistant materials (such as plastic and glass), and containers made of reactive metals such as iron and aluminum should be avoided; if the reaction system involves aqueous solutions, the pH value must be controlled, and it should be avoided to add them at the same time as strong reducing agents to prevent dangerous reactions; the equipment must be cleaned in time after operation to avoid residual crystals from deliquescing and corroding.
1. Is Copper(II) Chloride Dihydrate toxic? What are the safety limits?
It has moderate toxicity. The concentration of copper dust in the workshop should be <1 mg/m³, and the residue in water after treatment should be ≤1.0 mg/L.
2. How to prevent deliquescence and clumping during storage?
Keep it tightly sealed and store it in a dry environment with humidity <55%, using silica gel desiccant.
