For automotive engineers, AC technicians, and chemical procurement specialists, understanding the precise technical specifications of HFO-1234yf (R-1234yf) is paramount. This knowledge ensures correct application, safe handling, and optimal performance in modern vehicle air conditioning systems. As a leading HFO-1234yf manufacturer in China, we provide this detailed overview to support your purchasing and application decisions.

Chemical Identity and Composition

Chemical Name: 2,3,3,3-Tetrafluoro-1-propene
Molecular Formula: C₃H₂F₄ (or CF₃CF=CH₂)
Molecular Weight: 114.04 g/mol
CAS Number: 811-97-2

Physical Properties of HFO-1234yf

Understanding the physical properties is key to handling and using R-1234yf effectively. When you buy HFO-1234yf, these specifications are vital:

• Appearance: Colorless and clear gas/liquid.
• Odor: Odorless in its pure state.
• Boiling Point: -29 °C at 1 atm. This low boiling point is characteristic of refrigerants used in AC systems.
• Melting Point: -152 °C.
• Critical Temperature: 94.7 °C.
• Critical Pressure: 33.82 bar.
• Vapor Pressure (at 21.1 °C): 0.6067 kPa.
• Liquid Density (at 25 °C): 1.094 g/cm³. This indicates its density when in liquid form.
• Vapor Density (at 25 °C, Air=1): Approximately 3.93.

Environmental and Safety Data

These parameters are critical for regulatory compliance and safe usage:

• Ozone Depletion Potential (ODP): 0. This means R-1234yf does not harm the ozone layer.
• Global Warming Potential (GWP) (100yr): <1. This extremely low GWP is its primary advantage over R-134a, making it an environmentally sustainable choice.
• ASHRAE Safety Group Classification: A2L. This classification indicates it is mildly flammable, requiring specific safety measures during handling and servicing.

Purity and Quality Standards

For optimal performance and to avoid damage to AC systems, high purity is essential. Our products typically specify:

• Purity: ≥99.9%
• Moisture: ≤10 mg/kg
• Acidity (as HCl): ≤1.0 mg/kg
• Residue after evaporation: ≤100 mg/kg
