FAQ - Technical & Supply Chain
-
Q:
Is 2-tert-Butoxyethanol the same as 2-Butoxyethanol?
A: No. 2-tert-Butoxyethanol, also called Ethylene Glycol Mono-tert-Butyl Ether or ETB, is CAS 7580-85-0 with formula C6H14O2. 2-Butoxyethanol or Butyl Glycol is CAS 111-76-2 and has a different structure and regulatory profile. Confirm the tert-butyl identity and CAS number in the purchase specification. -
Q:
Which specifications should be compared for industrial ETB?
A: Confirm ETB assay by the stated chromatographic method, di-tert-butyl ether or other organic impurities, water, color, acidity where reported, sulfur and density or distillation data. The quotation and batch analysis should use the same methods because nominal purity is not a complete specification. -
Q:
What is 2-tert-Butoxyethanol used for?
A: ETB is evaluated as a high-boiling oxygenated solvent or chemical intermediate in coatings, water-based latex coalescing, cleaning and process applications. It is also considered for wetting, plasticizing or synthesis uses where its water miscibility, boiling point near 152 deg C and flammable-liquid profile are suitable. -
Q:
What are the key physical properties of 2-tert-Butoxyethanol?
A: ETB is a colorless, water-miscible liquid with formula C6H14O2 and molar mass about 118.17 g/mol. Common sources list density near 0.90 g/cm3, boiling point around 152 C, flash point about 47-55 C and refractive index near 1.416-1.42, so it should be treated as a flammable liquid. -
Q:
How should ETB be stored and handled?
A: Store in a cool, well-ventilated area in tightly closed, grounded containers or tanks away from heat, sparks, open flames and strong oxidizers. Use vapor controls during transfer, avoid static accumulation and follow the current safety information for PPE, spill and emergency response.
