glycerol    音标拼音: [gl'ɪsɚ,ol]
n. 甘油;丙三醇

甘油;丙三醇

glycerol
n 1: a sweet syrupy trihydroxy alcohol obtained by
saponification of fats and oils [synonym: {glycerol},
{glycerin}, {glycerine}]

Glycerin \Glyc"er*in\, Glycerine \Glyc"er*ine\, n. [F.
glyc['e]rine, fr. Gr. glykero`s, glyky`s, sweet. Cf.
{Glucose}, {Licorice}.] (Chem.)
An oily, viscous liquid, {C3H5(OH)3}, colorless and odorless,
and with a hot, sweetish taste, existing in the natural fats
and oils as the base, combined with various acids, as oleic,
margaric, stearic, and palmitic. It may be obtained by
saponification of fats and oils. It is a triatomic alcohol,
and hence is also called {glycerol}. See Note under
{Gelatin}.
[1913 Webster]

Note: It is obtained from fats by saponification, or, on a
large scale, by the action of superheated steam. It is
used as an ointment, as a solvent and vehicle for
medicines, and as an adulterant in wine, beer, etc.
[1913 Webster]


Glycerol \Glyc"er*ol\, n. (Chem.)
Same as {Glycerin}.
[1913 Webster]

  • is there any difference between glycerin and glycerol?
    In laboratory setting, is there a difference between glycerin and glycerol? There are some conflicting info on this topic
  • What is the pH of 1M Glycerol? - Chemistry Stack Exchange
    If the pKa of Glycerol is 14 15 How do you calculate the pH for it? I assume that the Henderson-Hasselbalch derivative that works for weak acids and bases is not applicable here
  • Can we predict the IMF strength of Acetone vs Glycerol?
    0 I was recently assigned a lab where I was to observe several properties of the chemicals Acetone and Glycerol then use my observations to predict their overall Intermolecular Force strength The properties I observed were: Surface Tension: Here, I found that Acetone had a much higher surface tension than Glycerol
  • inorganic chemistry - Hydrogen peroxide and glycerol combination . . .
    Is the mixing of store-grade hydrogen peroxide 3% and glycerol in the ratio of 1:2 (V V) at room temperature affecting the decomposition rate of hydrogen peroxide?
  • why is glycerol-3-phosphate not called glyceryl-3-phosphate?
    In the case of glycerol-3-phosphate, a component of phosphoglycerides, a major pathway involves the conversion of glycerol (generated from the hydrolysis of triglycerides) to glycerol-3-phosphate via the enzyme glycerol kinase So the emphasis here is that it is simply a glycerol molecule that has been phosphorylated
  • H-NMR Equivalent Protons and Coupling of Glycerol
    This might be confusing since both ends of the molecule are the same The difference is that the alcohol points to only one side of the molecule So, while the hydrogen atoms on carbons 1 and 3 on paper have the same environment, they are not chemically equivalent when looking at the whole molecule Concerning your second question: The chemical shift of protons on heteroatoms such as Oxygen
  • light - How can glycerol make glass objects disappear? - Chemistry . . .
    There's a famous experiment that uses glycerol (glycerin) to make glass objects 'disappear' A glass object becomes nearly invisible when filled with glycerol and immersed in a container of the same substance
  • synthesis - What is this brown liquid that I got when I boiled glycerol . . .
    I boiled a solution of glycerol and water at about 160 degree Celsius and got a brown liquid much less in volume (boiled off the entire water I think; also not so sure about the accurate temperature)
  • Explain the mechanism of glycerol solubility in ether. ?
    Water and glycerol are completely miscible - no insolubility at all According to the CRC Handbook, glycerol and diethyl ether are immiscible Of course, water and ether are also immiscible, but there is some slight solubility, so you might expect similar solubility between ether and glycerol
  • The Chemistry behind creating Polylactic Acid (PLA)
    The glycerol also helps to keep the starch stretched out by stabilizing it with hydrogen bonding Plasticizers (as the name would indicate) are additives that increase the plasticity of a plastic and make it more durable or flexible
