Ethylene glycol poisoning; Other names: Ethylene glycol toxicity, ethylene glycol overdose: Ethylene glycol: Specialty: Emergency medicine: Symptoms: Early: intoxication, vomiting, abdominal pain [1] Later: decreased level of consciousness, headache, seizures [1] Complications: Kidney failure, brain damage [1] Causes: Drinking ethylene glycol ...
Here, ethylene oxide is obtained as the overhead product, whereas the bottom product obtained is known as the glycol bleed. When ethylene oxide is scrubbed from the recycle gas with an aqueous solution, ethylene glycols (viz. mono-ethylene glycol, di-ethylene glycol and other poly-ethylene glycols) get unavoidably produced.
Polymerization of ethylene oxide is an exothermic process. Overheating or contaminating ethylene oxide with catalysts, such as alkalis or metal oxides, can lead to runaway polymerization, which can end in an explosion after a few hours. Polyethylene oxide, or high-molecular-weight polyethylene glycol, is synthesized by suspension polymerization.
Ethylene glycol is produced from ethylene (ethene), via the intermediate ethylene oxide. Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation. C 2 H 4 O + H 2 O → HO−CH 2 CH 2 −OH. This reaction can be catalyzed by either acids or bases, or can occur at neutral pH under elevated temperatures. The ...
The resulting product is two ethylene glycol molecules joined by an ether bond. [5] "Diethylene glycol is derived as a co-product with ethylene glycol (MEG) and triethylene glycol. The industry generally operates to maximize MEG production. Ethylene glycol is by far the largest volume of the glycol products in a variety of applications.
It is prepared by reacting 35 moles of ethylene oxide with each mole of castor oil. The resulting product is a mixture (CAS number 61791-12-6): the major component is the material in which the hydroxyl groups of the castor oil triglyceride have been ethoxylated with ethylene oxide to form polyethylene glycol ethers.
[81]: 162 As of 2014 the long-term effects of inhaled propylene glycol [228] [202] and glycerin were unknown. [224] Exposure to propylene glycol may cause eye and respiratory tract irritation. [ 15 ] Heated and aerosolized propylene glycol can turn into propylene oxide , which the International Agency for Research on Cancer (IARC) labels a ...
Macrogol 4000, pharmaceutical quality. Macrogol 3350, often in combination with electrolytes, is used for short-term relief of constipation as well as for long-term use in constipation of various causes, including in multiple sclerosis and Parkinson's disease patients (an often-overlooked non-motor symptom) as well as constipation caused by pharmaceutical drugs such as opioids and ...
