Introduction

Tetramethylguanidine (TMG), as an efficient and multifunctional chemical, has shown great application potential in many fields such as organic synthesis, medicinal chemistry, and fine chemicals. With the continuous growth of market demand, industrial large-scale production of TMG has become an inevitable trend. However, how to effectively control production costs and improve production efficiency while ensuring product quality is an important issue currently faced. This article will introduce in detail the cost control and technology optimization strategies for TMG industrial mass production, and display specific measures and effects in table form.

Basic properties of tetramethylguanidine

• Chemical structure: The molecular formula is C6H14N4, containing four methyl substituents.
• Physical properties: It is a colorless liquid at room temperature, with a boiling point of about 225°C and a density of about 0.97 g/cm³. It has good water solubility and organic solvent solubility.
• Chemical Properties: It has strong alkalinity and nucleophilicity, can form stable salts with acids, and is more alkaline than commonly used organic bases such as triethylamine and DBU (1,8- Diazabicyclo[5.4.0]undec-7-ene).

Cost control strategy

1. Raw material procurement

• Centralized Procurement: Through centralized procurement, the procurement cost of raw materials can be reduced. Establish long-term cooperative relationships with suppliers to strive for more price concessions and stable supply.
• Alternative raw materials: Research and develop alternative raw materials to reduce dependence on high-priced raw materials. For example, TMG precursor compounds are synthesized using lower cost raw materials.

2. Production process optimization

• Optimization of reaction conditions: By optimizing reaction conditions, such as temperature, pressure and catalyst selection, the conversion rate and selectivity of the reaction can be improved and the formation of by-products can be reduced.
• Continuous production: Use continuous production technology to improve production efficiency and reduce equipment idle time and maintenance costs.
• Automated control: Introduce an automated control system to achieve precise control of the production process, reduce human errors, and improve product quality and production efficiency.

3. Energy Management

• Energy-saving technology: Use energy-saving technology and equipment, such as efficient heat exchangers and energy-saving motors, to reduce energy consumption.
• Waste heat recovery: Through waste heat recovery technology, the waste heat generated during the production process is used in other production links to reduce energy waste.
• Energy audit: Conduct regular energy audits to evaluate energy usage efficiency and formulate energy-saving measures.

4. Waste disposal

• Waste reduction: Reduce waste generation by optimizing production processes. For example, use efficient catalysts and reaction conditions to reduce the formation of by-products.
• Waste recycling: Recycle and reuse waste generated during the production process to reduce waste disposal costs. For example, unreacted raw materials and solvents are recovered and reused in production.
• Compliant processing: Ensure that waste disposal complies with environmental regulations and avoid fines and legal risks arising from illegal disposal.

Technical optimization strategy

1. Catalyst optimization

• High-efficiency catalysts: Develop and use efficient catalysts to improve the conversion rate and selectivity of the reaction and reduce the amount of catalyst.
• Catalyst Recycling: Research catalyst recovery and regeneration technology to extend the service life of the catalyst and reduce the cost of the catalyst.

2. Reactor design

• High-efficiency reactor: Design and use efficient reactors to improve reaction efficiency and production efficiency. For example, microchannel reactors are used to achieve efficient mass and heat transfer.
• Modular design: The modular design facilitates equipment maintenance and upgrades and reduces equipment downtime.

3. Process optimization

• Process integration: Through process integration, intermediate steps are reduced and overall production efficiency is improved. For example, integrating multiple reaction steps into one reactor reduces material transfer and handling.
• Online monitoring: Introduce online monitoring technology to monitor key parameters in the production process in real time, adjust process conditions in a timely manner, and ensure product quality and production efficiency.

4. Environmental protection

• Cleaner Production: Use cleaner production technology to reduce pollutant emissions. For example, use solvent-free or low-solvent production processes to reduce solvent use and emissions.
• Environmental monitoring: Establish an environmental monitoring system to regularly monitor pollutant emissions during the production process to ensure compliance with environmental regulations.
