CONT

If you see a chemical compound with the "ol" as a suffix its an alcohol. You can have a low molecular weight alcohol like methanol (CH3OH) or a high molecular weight alcohol like glycerol (CH2OH·CHOH·CH2OH). What they all have in common is what chemists call a functional group - in this case it's the OH group - called a hydroxyl group. The number of hydroxyl groups determine whether it's an alcohol or a polyol (containing more than one hydroxyl groups). The most common ones are what chemists call the lower alcohols. In order of increasing molecular weight they are: - Methanol. ... Ethanol. ... Pure, (undenatured) alcohol .... SDA [which] is the most important commercial from of ethanol. ... Industrial alcohol. ... CDA [which] is completely denatured alcohol .... Propanol. ... Butanol.

CONT

The physical properties of alcohols are influenced by the OH group. The lower alcohols are liquids, miscible with water and other hydrogen bonded liquids.

CONT

The lower alcohols, e.g. methanol, ethanol, are water-like liquids. They dissolve well in water, less well in other solvents.

DEF

higher alcohols: Monohydric alcohols with more than two carbon atoms which occur in small amounts in fermented and distilled liquors.

OBS

Higher alcohols [include] propyl, isopropyl, butyl, isobutyl, amyl, isoamyl, hexyl, heptyl, octyl, nonyl, and decyl alcohols.

CONT

Alcohol's are important solvents in finishing. If you see a chemical compound with the "ol" as a suffix its an alcohol. You can have a low molecular weight alcohol like methanol (CH3OH) or a high molecular weight alcohol like glycerol (CH2OH·CHOH·CH2OH). What they all have in common is what chemists call a functional group - in this case it's the OH group - called a hydroxyl group. The number of hydroxyl groups determine whether it's an alcohol or a polyol (containing more than one hydroxyl groups). The most common ones are what chemists call the lower alcohols.

CONT

The principle use [of ethylene oxide] is in the manufacture of ethylene glycol and higher alcohols which find important applications in automotive antifreeze, explosives, cellophane, polyester resins, synthetic fibers and rubbers, and hydraulic fluids. The higher alcohols such as di- and tri- are used as plasticizers, humectants, lubricants, and solvents.

Key term(s)
  • higher alcohols
  • high alcohols
  • superior alcohols

French

Domaine(s)
  • Éléments et composés chimiques
  • Distillerie (Alimentation)
DEF

Expression qui désigne les alcools propyliques, butyliques et amyliques apparaissant dans la fermentation alcoolique.

CONT

Alcools supérieurs. On les nomme ainsi car leur chaîne moléculaire est plus longue que celle de l'éthanol. Dans cette famille on trouve : le propanol, le méthyle 2 propanol 1, le butanol 1 et 2, le méthyle 2 et 3 butanol 1. Bien que produit en faible quantité (500 mg) lors de la fermentation alcoolique, ils contribuent, sous forme libre ou estérifiée, à l'identité et à la complexité des vins.

CONT

Corps résultants de matières azotées. [Ce] sont des alcools supérieurs (nombre d'atomes de carbones supérieur à 2). Composants essentiels de l'arôme secondaire (surtout avec les alcools dont le nombre de carbone est supérieur à 10).

Key term(s)
  • alcools supérieurs
  • alcools de masse moléculaire relative élevée
  • alcool de masse moléculaire élevée
  • alcools de masse moléculaire élevée
