∙ 15y ago
Glycerol can be contaminated with diethylene glycol if proper quality control measures are not followed during the production process. Diethylene glycol may be added unintentionally or as a result of cross-contamination if equipment is not properly cleaned between manufacturing different products. Diligent quality assurance practices are necessary to prevent contamination of glycerol with diethylene glycol.

What is the best solvent for glycerol?
The best solvent for glycerol is water because glycerol has high solubility in water. Other solvents that can be used include ethanol and propylene glycol.
What one what alcohols could be the alcohol portion of a wax ethylene glycol glycerol 1-triacontanol or none?
Ethylene glycol and glycerol are commonly used as alcohols in waxes. Triacontanol is not typically used in waxes but is used as a plant growth stimulant.
What is the alcohol in antifreeze called?
The most basic / simplest is Methanol Useful alternative #1 is Ethylene Glycol Useful alternative #2 is Propylene Glycol There are also non-glycol, "Organic Acid Technology" (OAT) antifreezes used in some automotive applications.
Best jet fuel freezing point depressant?
One effective jet fuel freezing point depressant is Diethylene glycol monomethyl ether (DiEGME). It is commonly used in aircraft fuels to lower the pour point and prevent freezing at high altitudes. Other additives such as ethylene glycol and methanol can also be used as freezing point depressants for jet fuel.
What is a Colourless viscous liquid a by-product of soap and used to make antifreeze?
Propylene glycol is a colorless viscous liquid that is a common by-product of soap production and is utilized in the manufacturing of antifreeze due to its ability to lower the freezing point of water.
What is the concentration of diethylene glycol allowed in toothpastes?
zero
What is Diethylene Glycol Monobutyl Ether?
Diethylene Glycol Monobutyl Ether is a solvent that is commonly used in various industries such as coatings, inks, and cleaners. It is known for its ability to dissolve a wide range of substances and is also used as a coupling agent in different formulations.
What is the best solvent for glycerol?
The best solvent for glycerol is water because glycerol has high solubility in water. Other solvents that can be used include ethanol and propylene glycol.
What structural feature makes glycerol a polar molecule?
The OH's in glycerol are what make it polor. They lead to the formation of a dipole. As they do in Alcohol and Glycol.
Di glycol amine molecular formula?
The molecular formula for diethylene glycol amine is C6H15NO2.
What one what alcohols could be the alcohol portion of a wax ethylene glycol glycerol 1-triacontanol or none?
Ethylene glycol and glycerol are commonly used as alcohols in waxes. Triacontanol is not typically used in waxes but is used as a plant growth stimulant.
What were some major problems caused by not testing drugs?
The sulfa drug in diethylene glycol, now the main ingredient in radiator antifreeze was used and people died from kidney failure.
Is Di-ethylene glycol a Multihydricalcohol?
No, diethylene glycol is not a multihydric alcohol. It is a diol, specifically an organic compound with two hydroxyl (alcohol) groups. Multihydric alcohols have more than two hydroxyl groups.
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.
Anhydride with ethylene glycol versus phthalic anhydride with glycerol?
Anhydride with ethylene glycol forms an ester, while phthalic anhydride with glycerol forms a polyester. The reaction with ethylene glycol typically involves the formation of a monomeric ester, while the phthalic anhydride with glycerol reaction leads to the formation of a polymeric structure due to the presence of multiple reactive sites on glycerol.
How it is possible Diethylene glycol boiling point is 245 while its auto ignition temp is 225 deg and how it is safe during its distillation as its auto ignition temp is lower than its boiling?
yes its possible
What are types of cryoprotectant?
1. DMSO 2. Ethylene glycol 3. Glycerol 4. 2-Methyl-2,4-pentanediol 5. Propylene glycol 6. Sucrose 7. Methylcellosolve 8. Dimethylformamide
