Product Description

Perfluorotriethylamine (PFTA)

CAS No.: 359-70-6

English Name: Perfluorotriethylamine / Tris(pentafluoroethyl)amine

Alias: Pentadecafluorotriethylamine

Molecular Formula: $\mathbf{C_6F_{15}N}$,Molecular Weight: 371.05

1. Basic Physical Properties (25 °C)

Appearance: Colorless, odorless transparent liquid
Density: 1.736 g/mL
Boiling Point: 68～69 °C (at atmospheric pressure)
Melting Point: −116.95 °C
Refractive Index $n_{D}^{20}$: 1.262
Solubility: Insoluble in water; poorly miscible with most organic solvents (typical fluorous biphasic characteristic)
Key Features: Non-flammable, ultra-low viscosity, low surface tension, excellent electrical insulation

2. Chemical Properties

High chemical inertness

Resistant to strong acids, strong alkalis, strong oxidants and reducing agents; non-corrosive to metals and most engineering plastics and rubbers at ambient temperature.
Perfluorinated tertiary amine structure

All C–H bonds are replaced by C–F bonds, featuring good thermal stability. The thermal limit is generally below 250 °C; slow decomposition occurs under extreme high temperature with release of fluorine-containing pyrolysis products.
Classified as a fluorous biphasic solvent, applicable for biphasic separation reaction systems.

3. Main Industrial Applications

Fluorinated fluid for electronics & semiconductors

Leak detection fluid for precision components, temperature control medium for wafer testing, cleaning agent for electronic parts.
Immersion liquid cooling / phase-change cooling medium

Low-boiling phase-change heat transfer fluid for servers, power devices and inverters.
Dielectric insulating liquid

Insulating coolant for high-voltage electrical equipment and aerospace devices.
Special inert solvent

Medium for fluorochemical synthesis and treatment of highly corrosive reagents.
Instrument isolating fluid, corrosion-resistant transmission fluid, precision leak testing medium.

Reference product: 3M FC-75 (Perfluorotributylamine). PFTA has a lower boiling point and is more suitable for medium-low temperature phase-change cooling.

4. Safety & Health (MSDS Highlights)

⚠️ Low toxicity, but not completely harmless

GHS Classification: Irritant (Xi)

H315 (Skin irritation), H319 (Serious eye irritation), H335 (May cause respiratory irritation)
Direct liquid contact degreases skin and may lead to dryness and erythema.
Inhalation of vapor may cause throat discomfort; Do not ingest.
Hazardous decomposition under combustion / high temperature: Produces highly toxic and corrosive fumes such as hydrogen fluoride (HF) and carbonyl fluoride.
6. Brief Comparison with Similar Fluorinated Liquids
- Perfluorotriethylamine (PFTA): bp ≈ 69 °C, widely used for low-boiling phase-change liquid cooling
- Perfluorotributylamine (FC-75): bp ≈ 102 °C, mainly used for leak detection and cleaning
- Novec series (hydrofluoroethers): Contains hydrogen, not perfluoroamine, differing in polarity and compatibility
