CAS No. 7580-85-0 Ethylene Glycol Mono-Tert-Butyl Ether/Etb/Ethylene Glycol Tertiary Butyl Ether 

Short Description:

Ethylene glycol butyl ether (EGBE) is an ethylene oxide-based glycol ether solvent commonly used in the coatings industry. Its relative evaporation rate with respect to n-butyl acetate has been reported to be 0.07. Its toxicity has been assessed.The effect of EGBE as a thickening solvent during acrylic latex synthesis has been investigated.2-Butoxyethanol is a glycol ether with modest surfactant properties, which can also be used as a mutual solvent.

Storage Precautions

2-Butoxyethanol is commonly produced for the oil industry because of its surfactant properties.

In the petroleum industry, 2-butoxyethanol is a component of fracturing fluids, drilling stabilizers, and oil slick dispersants for both water-based and oil-based hydraulic fracturing.[clarification needed] When liquid is pumped into the well, the fracturing fluids are pumped under extreme pressure, so 2-butoxyethanol is used to stabilize them by lowering the surface tension.As a surfactant, 2-butoxyethanol absorbs at the oil-water interface of the fracture.The compound is also used to facilitate the release of the gas by preventing congealing.It is also used as a crude oil–water coupling solvent for more general oil well workovers.

2-Butoxyethanol most commonly enters the human body system through dermal absorption, inhalation, or oral consumption of the chemical.The ACGIH threshold limit value (TLV) for worker exposure is 20 ppm, which is well above the odor detection threshold of 0.4 ppm. Blood or urine concentrations of 2-butoxyethanol or the metabolite 2-butoxyacetic acid may be measured using chromatographic techniques. A biological exposure index of 200 mg 2-butoxyacetic acid per g creatinine has been established in an end-of-shift urine specimen for U.S. employees.2-Butoxyethanol and its metabolites fall to undetectable levels in urine after about 30 hours in men.

Advantage

Product quality, sufficient quantity, effective delivery, high quality of service It has an advantage over a similar amine, ethanolamine, in that a higher concentration may be used for the same corrosion potential. This allows refiners to scrub hydrogen sulfide at a lower circulating amine rate with less overall energy usage.
