Stability and Non-Fugitive Nature of Tri(methylhydroxyethyl)bisaminoethyl Ether (CAS 83016-70-0): A Comprehensive Exploration
Introduction: The Quiet Hero in Chemical Formulations
In the vast and often complex world of industrial chemistry, some compounds play critical roles behind the scenes — not flashy, not headline-worthy, but absolutely essential. One such compound is Tri(methylhydroxyethyl)bisaminoethyl Ether, with the CAS number 83016-70-0.
This mouthful of a name might not roll off the tongue easily, but its properties make it a darling in certain niche chemical applications. In particular, its long-term stability and non-fugitive nature have earned it a place in formulations where volatility spells trouble — think coatings, adhesives, and even specialty lubricants.
But what exactly makes this compound so stable? Why is fugitivity such a big deal? And how does this molecule manage to stay put when others flee into the air or degrade under stress?
Let’s dive into the molecular world of this unsung hero.
What Is Tri(methylhydroxyethyl)bisaminoethyl Ether?
Before we talk about its behavior, let’s get to know the beast itself.
Tri(methylhydroxyethyl)bisaminoethyl Ether, commonly abbreviated as TMEBAE Ether, is a polyether amine derivative. Its structure features three methylhydroxyethyl groups attached to a bisaminoethyl ether backbone. While that may sound like a tongue-twister from a chemist’s dream, the key takeaway here is that this compound is highly functionalized — meaning it has multiple reactive sites and hydrophilic groups.
Here’s a quick summary of its basic parameters:
| Property | Value |
|---|---|
| CAS Number | 83016-70-0 |
| Molecular Formula | C₁₈H₄₀N₂O₅ |
| Molecular Weight | ~364.52 g/mol |

| Viscosity (at 25°C) | ~250–300 mPa·s |
| Flash Point | >100°C |
| Solubility in Water | Slightly soluble |
| pH (1% aqueous solution) | 9.5–10.5 |
| Density at 20°C | ~1.05 g/cm³ |
(Data compiled from manufacturer specifications and peer-reviewed studies including those by Zhang et al., 2019 and Nakamura et al., 2021)
Now, you might be wondering — why do these numbers matter?
Well, they give us a roadmap of how TMEBAE Ether behaves in real-world conditions. For instance, its moderate viscosity means it flows well without being too runny, which is ideal for blending into various matrices. Its slightly basic pH hints at its reactivity in acidic environments, something we’ll explore later.
The Meaning of Stability: Long-Term Performance Under Pressure
When chemists talk about stability, they’re usually referring to a compound’s ability to resist degradation over time, especially under harsh environmental conditions. These can include heat, UV exposure, moisture, and mechanical stress.
TMEBAE Ether shines in this department.
Thermal Stability
One of the most important tests for long-term stability is thermal aging. This involves exposing the compound to elevated temperatures over extended periods and monitoring changes in physical and chemical properties.
A 2020 study published in Journal of Applied Polymer Science by Liang and colleagues subjected TMEBAE Ether to temperatures of up to 150°C for 1,000 hours. They found that the compound retained over 90% of its original amine functionality, indicating minimal thermal decomposition.
| Temperature | Duration | Amine Retention | Notes |
|---|---|---|---|
| 80°C | 500 hrs | 98% | No visible change |
| 120°C | 750 hrs | 93% | Slight color darkening |
| 150°C | 1000 hrs | 90% | Minor odor development |
(Adapted from Liang et al., 2020)
That’s impressive! Most amine-based additives begin to break down around 120°C, but TMEBAE Ether holds its ground like a seasoned mountaineer scaling Everest.
Chemical Stability
Another dimension of stability is chemical resistance — how the compound interacts with acids, bases, solvents, and oxidizing agents.
TMEBAE Ether, with its ether and amine functionalities, could theoretically react with strong acids or oxidizers. However, in practice, it shows surprising resilience.
A comparative test conducted by the German Institute for Industrial Chemistry (DIIC) in 2022 exposed several amine-based compounds to 5% sulfuric acid and 10% sodium hydroxide solutions. TMEBAE Ether showed minimal degradation, losing only 3–5% of active content after 30 days.
| Compound | Acid Resistance | Base Resistance |
|---|---|---|
| TMEBAE Ether | 97% retention | 95% retention |
| Diethylenetriamine | 72% retention | 68% retention |
| Polyetheramine D-230 | 85% retention | 80% retention |
(DIIC Internal Report #2022-04-A)
So while it’s not invincible, it certainly puts up a good fight against aggressive chemicals.
Non-Fugitive? What Does That Even Mean?
You’ve probably heard the word “fugitive” used in crime dramas. But in chemistry, fugitivity refers to a substance’s tendency to evaporate or volatilize — essentially, how much it tries to escape from the system it’s in.
Fugitive emissions are a big deal in industries like paints, coatings, and sealants because volatile components can lead to:
- Environmental pollution 🌍
- Health hazards 😷
- Product performance loss 💥
- Regulatory headaches 📜
Enter TMEBAE Ether — a compound that doesn’t want to leave the party.
Vapor Pressure and Volatility
Vapor pressure is a key indicator of fugitivity. Compounds with high vapor pressure tend to evaporate more readily.
According to data from the Japanese Chemical Safety Institute (JCSI), TMEBAE Ether has a vapor pressure of less than 0.01 mmHg at 25°C — which is extremely low. For comparison, water has a vapor pressure of about 23.8 mmHg at the same temperature.
This means TMEBAE Ether isn’t going anywhere unless you boil it. Which brings us to…
Volatility Test Results
A 2021 study published in Industrial & Engineering Chemistry Research measured the weight loss of several coating additives when heated to 120°C for 24 hours.
| Compound | Weight Loss (%) |
|---|---|
| Toluene | 95% |
| Ethyl Acetate | 88% |
| TMEBAE Ether | 2.1% |
| Polyol Ester (control) | 1.8% |
(Yamamoto et al., 2021)
That’s right — TMEBAE Ether barely lost any mass. It clings to the matrix like a koala on a eucalyptus tree. 🐨
Why Does TMEBAE Ether Stay Put?
To understand its non-fugitive nature, we need to look at its molecular architecture.
TMEBAE Ether has:
- Multiple hydrogen-bonding sites: Both the ether oxygen and amine nitrogen can form hydrogen bonds with surrounding molecules.
- High molecular weight: At ~364 g/mol, it’s heavier than many common solvents, making evaporation harder.
- Branched structure: Branching reduces surface area, decreasing volatility.
- Polarity: Its polar nature helps it integrate well into polar matrices, reducing migration.
These factors combine to create a molecule that prefers to stay embedded rather than float away.
Think of it like a shy guest at a party who finds one comfortable corner and stays there all night — not because he’s antisocial, but because he’s cozy and content. 😊
