1、 Clarify experimental requirements and reaction conditions

1. Pressure and temperature range

High pressure reactions require the selection of pressure resistant titanium reactors, with a design pressure that should be 20% to 30% higher than the experimental pressure.

The all titanium structure is suitable for small and medium-sized containers with temperatures ≤ 250 ℃ and pressures ≤ 0.5MPa. In high-temperature and high-pressure scenarios, composite titanium or titanium lining design should be considered.

2. Corrosive medium

Titanium material is resistant to chloride corrosion, but strong oxidizing media should be avoided.

The composite titanium reactor is suitable for most chemical environments due to its high cost-effectiveness and balanced corrosion resistance.

2、 Material and Structure Selection

1. Material type

Pure titanium reactor: Good corrosion resistance, but high cost, suitable for high-purity or special environments.

Composite titanium reactor: Balancing performance and cost, widely used in fields such as petrochemicals and pharmaceuticals.

Titanium lined reactor: lined with a titanium layer, suitable for large-scale equipment or scenarios that require cost reduction.

2. Structural Design

The thickness of the shell should be ≥ 2mm to ensure welding process and transportation safety.

It is recommended to choose magnetic drive for the mixing system to avoid the risk of mechanical seal leakage.

3、 Safety and temperature control configuration

1. Safety device

It is necessary to equip with over temperature and over pressure alarm, automatic pressure relief valve, and explosion-proof membrane. The high-pressure reactor should have pressure interlock function.

The electrical part must comply with explosion-proof standards.

2. Temperature control system

High temperature reactions require electric heating sleeves or circulation of thermal oil, while low-temperature reactions require confirmation of the low-temperature resistance of the sealing material.

The recommended temperature control accuracy is ± 1 ℃ to ensure experimental reproducibility.

4、 Operation and maintenance considerations

1. Convenience of operation

Priority should be given to designs with quick loading interfaces and openable kettle covers for easy feeding and cleaning.

Continuous sampling requires the configuration of a sampling valve to avoid frequent lid opening.

2. After sales service

Choose brands that offer a warranty of at least 1 year to ensure that critical components are easily replaceable.

5、 Typical application scenarios

Petrochemical industry: reactions such as sulfurization, nitration, hydrogenation, etc., composite titanium reaction kettle is recommended.

Medicine/Food: When high cleanliness is required, pure titanium or titanium lined reaction vessels can be selected.

Aerospace: The high strength and lightweight properties of titanium are suitable for the synthesis of special materials.
