In the intricate world of chemical trading, precision and quality matter most. And, when it comes to evaluating the quality of Diethylene Glycol (DEG). you need to pay meticulous attention.
Whether you are an experienced and knowledgeable chemical trader, factory owner or procurement or supply chain manager, you know well the significance of procuring the finest materials to uphold your company’s reputation and maintain a competitive edge.
Today’s blog covers DEG or Diethylene Glycol. You get to know about this versatile organic compound, its uses and how to check the quality of DEG.
DEG at a quick glance
DEG has the chemical formula C4H10O3. It is a colorless, virtually odorless and hygroscopic liquid and it has a mildly sweet taste. The interesting fact is- the properties of DEG are similar to Monoethylene Glycol (MEG). However, DEG boasts a higher boiling point, viscosity and specific gravity. The benefit of using DEG is – it is a valuable choice for various applications.
Let’s know about the various applications of DEG
Textile – DEG is highly used in the textile industry. It is used as a solvent to help those vibrant dyes really pop, and it even lends a hand in creating polyester fibers.
Pharmaceutics – In the world of medicine, DEG plays the role of a trusty carrier. Meaning it helps to deliver those life-saving drugs and formulations.
Plasticizer – You know how some plastics can be a bit stiff and brittle? Well, DEG acts as a plasticizer. Meaning, it gives them a little extra flexibility and durability.
Cosmetic – DEG isn’t just for industrial use. It’s also used in the cosmetic world. It is used in skin creams and lotions to keep skin feeling silky smooth.
Automotive – Vehicles would not be complete without a little DEG action. In other words, DEG here acts as an ingredient in antifreeze that keeps your engine running cool.
How to check the quality of DEG
When it comes to assessing the quality of DEG, there are a bunch of tests to run.
Appearance – First up, we’ve got the appearance test. DEG should be a clear liquid, just like water. So if it’s looking a little cloudy or funky, that’s a red flag right there.
Color – Color is another important factor. DEG should be essentially colorless, with a maximum color value of 15 on the Pt-Co scale. In simpler terms, if it’s starting to look a little yellow or discolored, it might not be good to go with.
MEG and TEG – For MEG, it should be less than 0.2%, and for TEG, less than 0.5%. Too much of these, and they could mess with your end product.
Gravity – Next, we check the specific gravity at 20°C. This term just means how dense the liquid is compared to water. For DEG, we’re looking for a reading between 1.1175 and 1.1195.
Assay – Now, let’s talk about the assay – this is basically a measure of how pure the DEG is. You should always look for DEG with a minimum of 99.5% purity.
Acidity – Acidity is a biggie, too. You need to make sure the acidity level (measured as acetic acid) is no more than 50 parts per million (ppm). Anything higher, and you might have a problem on your hands.
Water – Finally, you need to check the water content. DEG shouldn’t have more than 0.2% water, or it could cause some issues down the line.
