Titanium Anode for Succinic Acid Electrolysis

​​​​​​​Titanium Anode for Succinic Acid Electrolysis

In the electrochemical synthesis of succinic acid (butanedioic acid), the catalytic selectivity and stability of the anode play a decisive role in product yield and purity. Our Titanium Anode for Succinic Acid Electrolysis at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically for the electrochemical hydrogenation of maleic acid to succinic acid. It uses Grade 1 or Grade 2 pure titanium as the substrate, with a noble metal oxide catalytic coating on the surface. The coating maintains a stable oxygen evolution potential in acidic electrolytes containing maleic acid and its derivatives, while providing a favorable catalytic interface for the electrochemical conversion of organic molecules. During long-term operation, the anode minimizes the risk of metal ion dissolution, helping maintain the purity of both the electrolyte and the product, making it a reliable electrode solution for the industrial production of succinic acid via electrosynthesis.

Why Choose Our Titanium Anodes?

• Catalytic Selectivity for Organic Electrosynthesis
  The electrosynthesis of succinic acid involves the cathodic hydrogenation reduction of maleic acid, with the anode side primarily responsible for providing a stable oxygen evolution reaction to complete the current circuit. Our iridium-based coating maintains good oxygen evolution activity in acidic electrolytes containing organic substrates, while minimizing excessive oxidation of organic molecules. This helps avoid substrate consumption and product decomposition caused by anode side reactions, contributing to high current efficiency and product yield.
• Chemical Stability in Acidic Organic Media
  The electrolyte formed by maleic acid and its derivatives, together with auxiliary electrolytes such as sulfuric acid, is acidic and presents a continuous corrosion challenge to electrode materials. Our coating formulation is optimized to maintain a low corrosion rate and good structural integrity in such acidic organic media, making it suitable for long-cycle continuous industrial electrosynthesis processes.
• Material System Designed to Reduce Product Contamination Risk
  The titanium substrate and noble metal oxide coating form a chemically stable bond in organic acid electrolytes, minimizing the dissolution of metal ions into the electrolyte. For succinic acid products with high-purity requirements, the low risk of impurity introduction from the anode side is an important factor in maintaining final product quality.
• Customization Capability for Various Electrolyzer Configurations
  We can supply flat plate, perforated mesh, and perforated plate anodes, compatible with filter-press diaphragm cells, flow electrolyzers, and continuously stirred tank reactors. Based on your cell dimensions, electrode spacing, and fluid distribution requirements, anode profiles, open area ratios, and conductive connection methods can be customized.

Real-World Applications

• Organic Acid Electrosynthesis Process Development: Used in the R&D and pilot-scale development of new electrosynthesis processes for organic acids such as maleic acid, fumaric acid, and oxalic acid.
• Electrochemical Hydrogenation and Organic Transformation: Used in fine chemical electrosynthesis processes involving electrocatalytic hydrogenation or oxidative transformation of other organic molecules.

The ShenAo Advantage

17 A long time of Fabricating Excellence

Since 2008, we've specialized in valuable metal coated titanium anodes from our office in Baoji's "China Titanium Valley." Our develop bimetallic hazardous welding innovation and progressed coating forms provide items you can trust.

Customization for Your Correct Needs

Every generation line is diverse. We give custom fitted arrangements coordinating your particular current thickness necessities, electrolyte composition, and operational parameters. Whether you require little bunch testing or full-scale generation amounts, we convey on time.

Cost-Effective Lifecycle Management

When coating exhaustion happens, you do not dispose of the whole anode. Our proficient recoating benefit strips the ancient oxide layer, sandblasts the substrate, and reapplies new MMO coating. This expands resource life and decreases your add up to taken a toll of proprietorship considerably.

Frequently Asked Questions

Q: What type of coating is suitable for succinic acid electrolysis anodes?
A: The electrolyte for succinic acid electrosynthesis is typically acidic and contains organic substrates, with the anode primarily facilitating the oxygen evolution reaction. Iridium-based coatings demonstrate good oxygen evolution activity and chemical stability in such environments, while being less prone to catalyzing excessive oxidation of organic molecules. If your electrolyte contains chloride ions or uses a different electrolyte system, the coating formulation can be adjusted accordingly. We recommend providing specific process parameters so we can recommend the most suitable solution.

Q: How can I determine whether the anode coating is suitable for my existing electrolysis process?
A: The main factors to consider are electrolyte acidity, organic substrate concentration, operating temperature, and current density. You can provide your existing process parameters and electrolyte composition, and our engineers will assess the chemical compatibility and estimated service life of the coating. If necessary, small-sized samples can be provided for on-site coupon testing to verify performance under actual operating conditions.

Q: What should be noted during long-term operation of anodes in organic electrosynthesis?
A: In organic electrosynthesis, the anode surface may accumulate polymer films or adsorb intermediate products from organic side reactions, leading to a gradual reduction in active surface area and an increase in cell voltage. We recommend establishing regular cell voltage monitoring records and scheduling periodic online or offline chemical cleaning based on operating conditions to restore anode surface activity. The content of solid particulates and colloidal impurities in the electrolyte should also be controlled to avoid physical wear on the coating.

Q: How should anodes be handled when the coating reaches the end of its service life?
A: The titanium substrate remains stable in acidic organic electrolytes, and the old coating can be chemically stripped. Once the substrate passes inspection, it can be recoated to restore performance to new-anode levels. We offer a full-service process including incoming inspection of used anodes, coating stripping, substrate treatment, and recoating. This remanufacturing approach can yield meaningful long-term savings compared to purchasing entirely new anodes.
