C₃H₆

High-Purity Propylene

High-Purity Propylene is an electronic specialty gas produced by Jinhong Gas using patented purification technology, with a purity of up to 99.995% (4.5N). It is a colorless, slightly sweet-smelling, flammable gas. As a key fundamental material, it is indispensable in semiconductor manufacturing, new energy batteries, and advanced display industries. With extremely low impurity content and high stability, this product meets the most stringent requirements of electronic industry applications.

Process

Jinhong Gas adopts a mature process that combines multi-stage adsorption separation and multi-stage rectification technology. The feed gas first passes through a dedicated molecular sieve adsorption system to deeply remove impurities such as moisture and carbon dioxide. It then enters the core cryogenic rectification system, where a light-component removal column and a heavy-component removal column precisely separate components with different boiling points—light components (such as H₂, O₂, CH₄) and heavy components (such as C₃H₈). This process ensures the continuous and stable production of high-purity propylene with a purity level of 4.5N.

Frequently Asked Question

How can the actual purity of the product be verified?

We provide a Certificate of Analysis (COA) for each batch, based primarily on gas chromatography testing. Customers may also verify through accredited third-party testing agencies.

What should be checked before opening the cylinder?

Inspect the cylinder for integrity, ensure that the pressure regulator is clean and dry, and purge the pipeline system with high-purity inert gas to prevent air contamination.

What is the product packaging format?

Currently supplied in DOT 47L cylinders, equipped with DISS 724 / CGA 350 valves, with a filling weight of 13 kg.

What should be done in case of leakage?

Immediately eliminate all ignition sources, evacuate non-essential personnel, shut off the leak source if possible, ensure proper ventilation, and contact professional emergency response teams.

Can this product be used directly in food-related applications?

No. This is an industrial-grade high-purity gas. Although its purity is extremely high, it has not obtained food-grade certification and is not suitable for food processing or preservation purposes.

Is the purity consistent across different batches?

Yes. Our strict quality control system ensures stable purity in every batch. A detailed Certificate of Analysis is provided to guarantee consistency.

How to choose the proper regulator and pipeline materials?

It is recommended to use stainless steel regulators and pipelines with electropolished inner walls. Avoid copper, rubber, or other materials that may introduce impurities.

How should residual gas be handled?

Maintain at least 0.2 MPa residual pressure in the cylinder to prevent backflow of air. Waste gas disposal must comply with local environmental regulations and be handled by certified professionals.

What precautions should be taken during transportation?

Transportation must comply with hazardous chemical transportation regulations. Cylinders should be securely fastened, protected from direct sunlight and rain, transported separately from oxidizers, and accompanied by appropriate fire-fighting equipment.
