glycerol    音標拼音: [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?
    glycerols are the triol compound used for many purposes in pure or mixed form , but glycerine is the commercial name of glycerol, which is not pure ,which contain mostly 95% of glycerol , it can't be used when pure glycerol is required
  • Will glycerol and citric acid react? If yes, under what conditions?
    Polyesters of glycerol and citric acid were studied with differential scanning calorimetry and thermal gravimetric analysis The polyesters were found to be thermally stable (up to 313°C) A noble application of glycerol + citric acid esters or citroglycerides is in the making of a biodegradable thermoset polymers 1 Source 1
  • Why is the IUPAC name of glycerol expressed in the way that it is?
    Glucose, glycogen, and glycerin (another name for glycerol) have the same etymology Trihydroxypropane makes sense as a common name because there are only 3 locations for the hydroxyl groups on the 3 carbon chain, so the name is basically unambiguous - multiple hydroxyl groups on the same carbon are not stable (see geminal diols)
  • What is the pH of 1M Glycerol? - Chemistry Stack Exchange
    The answer is approximately 6 88 Therefore a $1\ M$ solution of glycerol in water will be ever so slightly acidic (considering that the hydroxyls are much weaker bases than acids, i e that the equilibrium constant for the reaction $\ce{C3H7O2OH + H2O <=> C3H7O2O^- + H3O^+}$ is much larger than the constant for $\ce{C3H7O2OH + H2O <=> C3H7O2OH2^+ + OH^-}$, which may or may not be true
  • inorganic chemistry - Hydrogen peroxide and glycerol combination . . .
    Hydrogen peroxide oxidizes glycerol to various reagents A possible reaction pathway can be depicted as follows (Ref 1): This reaction is catalyzed by transition metals and other substances (Ref 1-3)
  • Is glycerol glycerin soluble in ethanol? - Chemistry Stack Exchange
    As LDC3 indicated above here it states that "Glycerol is completely soluble in water and alcohol " So, this is correct, as also indicated here Now, for the reason this happens it is most likely because of its 3 hydroxyl groups ($-OH$) and the fact that it is a polar molecule
  • synthesis - What is this brown liquid that I got when I boiled glycerol . . .
    If i had to guess I'd say that at 160 C you've managed to completely obliterate any complicated organic structures and what's left is glycerol, charcoaled bits of any organic impurities that you happened to have in the starting material and possibly some acrolein which is a common product of dehydration of glycerol (you can recognize it by it's
  • 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
  • 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 Changing the amount of glycerol in the recipe can have a big effect on the strength of the plastic film you make
  • Electrolysis of calcium hydroxide in glycerol [closed]
    Calcium hydroxide is probably slightly soluble in glycerine due to tight chelation of Ca++ ion by the three hydroxyls of (probably 2) glycerine(s)
