MONOHYDRIC [5 records]

Record 1 2023-05-16

English

Subject field(s)
  • Analytical Chemistry
  • Soil Science
DEF

total concentration (for organics): The concentration derived by applying an analytical technique that cannot distinguish between similar [organic] compounds.

OBS

Such a technique would be one that, in the case of phenols for example, cannot distinguish, between monohydric, dihydric and trihydric compounds.

OBS

The term "total" may be misleading. For example, not all phenols may be detected by the method, and different methods may give different results.

OBS

total concentration for organics: The term "total concentration (for organics)" has been standardized by the International Organization for Standardization (ISO).

French

Domaine(s)
  • Chimie analytique
  • Science du sol
DEF

concentration totale (pour les matières organiques) : Concentration obtenue en appliquant une méthode analytique ne pouvant faire la distinction entre des composés [organiques] similaires.

OBS

Il s'agirait d'une méthode analytique ne pouvant pas faire par exemple, dans le cas des phénols, la distinction entre entre les composés monohydriques, dihydriques et trihydriques.

OBS

Le terme «total» peut être trompeur. Par exemple, la méthode employée ne permet pas de détecter tous les phénols, et différentes méthodes peuvent donner des résultats différents.

OBS

concentration totale pour les matières organiques : Le terme «concentration totale (pour les matières organiques)» a été normalisé par l'Organisation internationale de normalisation (ISO).

Record 2 2003-02-06

English

Subject field(s)
  • Chemical Elements and Compounds
  • Distilling Industries (Food Ind.)
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)

  • high alcohols
  • superior alcohols

Domaine(s)

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

Record 5 2001-01-10

English

Subject field(s)
  • Chemical Elements and Compounds
CONT

In reference to monohydric alcohols, amines, and a few related compounds, this term [primary], together with secondary and tertiary, describes the molecular structure of isomeric or chemically similar individuals. Monohydric alcohols are based on the methanol group,-C-OH, in which three of the bonds [up, down and left side] of the methanol carbon may be attached either to hydrogen atoms or to alkyl groups.... A secondary alcohol has two alkyl groups and one hydrogen.... The three types can be readily identified by the number of hydrogen atoms attached to the central(methanol) carbon atom : if it is 2 or more, the alcohol is primary; if 1, it is secondary; and if zero, it is tertiary. For example, CH3CH2OH; is primary;(CH3) CHOH; is secondary;(CH3) 3COH is tertiary.

French

Domaine(s)
  • Éléments et composés chimiques
DEF

Nom générique des alcools renfermant le groupement bivalent -CHOH-.

CONT

On distingue trois classes d'alcools, selon le nombre d'atomes d'hydrogènes attachés à l'atome de carbone porteur du groupe OH : les alcools tertiaires R3COH, les alcools secondaires R2CHOH et les alcools primaires RCH2OH (auxquels se rattache le méthanol CH3OH).
