What are the differences between polyethylene oxide and polyethylene glycol?
Polyethylene oxide and polyethylene glycol are both polymers made of repeating ethylene glycol units. The main difference between them is their molecular weight. Polyethylene oxide has a lower molecular weight and is a liquid at room temperature, while polyethylene glycol has a higher molecular weight and is a solid or semi-solid at room temperature. Additionally, polyethylene glycol is commonly used in pharmaceuticals and cosmetics, while polyethylene oxide is used in industrial applications.
What is the weight of glycol?
The weight of glycol will depend on the quantity!
What is the molecular formula of ethylene glycol if mass is 62amu?
The molecular formula of ethylene glycol is C2H6O2. Given that the molar mass of ethylene glycol is 62 amu, it confirms that the molecular formula is correct, as the sum of the atomic masses of carbon (C), hydrogen (H), and oxygen (O) in one molecule of ethylene glycol equals 62 amu.
Is PEG soluble in Tetrahydrofuran?
Polyethylene glycol (PEG) is generally soluble in tetrahydrofuran (THF). THF is a polar aprotic solvent, and PEG, being a polar compound, can dissolve in it. However, the solubility can depend on the molecular weight of PEG; lower molecular weight PEGs tend to be more soluble in THF compared to higher molecular weight variants.
Is polyethylene glycol used in auto antifreeze?
Yes, polyethylene glycol is commonly used as a base ingredient in automotive antifreeze and coolant products due to its ability to lower the freezing point of water and prevent engine coolant from freezing in cold temperatures.
Di glycol amine molecular formula?
Diglycolamine has a molecular formula of C4H11NO2. This means it has 4 carbon atoms, 11 hydrogen atoms, a single nitrogen atom, and two oxygen atoms.
How long will a bear live after ethylene glycol poisoning?
Ehtylene glycol is the primary ingredient of antifreeze and hydraulic brake fluit. Survival and the time depends on the amount of ethylene glycol and the weight of the bear. 120ml might kill an average sized man. Based on that about 240ml might kill a bear. Death might occur in roughly 12-36h.
In which solvent poly ethylene glycol dissolves?
It depends on both the molecular weight and the geometry of the particular polymer. Low molecular weight PEG's are generally water-miscible liquids, high MW ones are waxes insoluble in pretty much any common solvent.
What type of antifreeze for 2006 Chevrolt Impala?
The GM brand name is "DEXCOOL". This is the orange colored extended life coolant. All anti-freeze makers make this type of coolant. The older green coolant is ehtylene glycol based, then Dexcool is not. - TechJK -----------------------------------------
Why is glycerol heavier than ethylene glycol?
Glycerol is heavier than ethylene glycol because it has a higher molecular weight and more hydroxyl groups, which contribute to its increased density. This increased density results in a higher mass per unit volume compared to ethylene glycol.
How much does a liter of propylene glycol weigh?
The weight of a liter of propylene glycol is approximately 1.036 kilograms.
Is c2h6o2 Ionic or molecular?
C2H6O2, which is ethylene glycol, is a molecular compound. It consists of covalent bonds between the carbon, hydrogen, and oxygen atoms.
