Measuring the Purity of Mono Ethylene Glycol (MEG)

If you’re running a business and need to order purest quality Mono Ethylene Glycol (MEG) for the production of polyester fibers and resins, for moisture removal from natural gas and air systems, etc. reasons, you just found the right blog.

Before we go into deeper discussion, let’s find out what exactly MEG is and why its purity matters so much. 

In simple words, MEG or Mono Ethylene Glycol is a colorless, odorless liquid with a sweet taste. This organic compound(chemical formula C2H6O2) is like a silent guardian, playing crucial roles in various applications.

Measuring the Purity of Mono Ethylene Glycol (MEG)

First things first, MEG is the secret ingredient in antifreeze, doing the magic of lowering the freezing point of water. This means no more worries about engines or pipelines freezing up – MEG’s got it covered.

But wait, there’s more. MEG is a bit of a moisture magnet, with high hygroscopic properties. It can remove moisture from natural gas and air systems, keeping things dry and running smoothly.

Now, here’s where MEG steps into the spotlight – polyester production. It’s the MVP in creating those cozy polyester fibers, films, and resins. 

And here’s the best part – MEG is a versatile chemical intermediary, and that’s why Mono Ethylene Glycol uses are enormous. 

However, whatever the purpose is, measuring the purity of MEG is very crucial for the best outcome. 

Checking out the MEG Purity Checklist

But how do you make sure your MEG is top-notch? Let’s break it down 

Appearance – First things first – give your MEG a good look. It should be crystal clear, just like water. If it looks funky, that’s a red flag waving at you.

Purity – Now, purity is the VIP here. It should be at least 99.0%, but guess what? Make sure the Mono Ethylene Glycol supplier offers you MEG 99.9%. The best MEG manufacturers make use of ASTM E202 standard – it’s like the purity report card for MEG.

Diethylene Glycol and Other Glycols – Keep an eye out for diethylene glycol and other glycols – they’re the unwanted party crashers. There should not be more than 0.5% for diethylene glycol and 0.1% for the other glycols. ASTM E202 is the superhero standard keeping them in check.

Refractive Index and Specific Gravity – The refractive index should be at 25ºC and the specific gravity at 20ºC. Top manufacturers mostly aim for 1.431 and 1.1155, respectively. They may use ASTM D891 and D203 standards to help them measure these.

Color – Let’s talk colors – but not in an artsy way. This is measured in Pt-Co units, and there should be a maximum of 15. A sleek 5.0. 

Acidity (as acetic acid) – Now it’s time for some acidity talk. Top MEG manufacturers measure it as a percentage, and there is a maximum of 0.005%. Following the ASTM D1613 standard makes it clear that the MEG is acid-free.

Distillation Range – Things heat up with the distillation range – it’s when MEG goes from liquid to vapor. The range is 195-198°C.

Ash and Water Content – Lastly, let’s there is ash and water content. There should be 0.0045% for ash and 0.3% for water. ASTM E347 and E203 are the standards that manufacturers follow to meet the purity level.
