Chemical Properties
clear liquid
Occurrence
Reported found in cognac, white wine and red wine.
Uses
2,6-Dimethyl-4-heptanol may be used in the preparation of the protected β-hydroxybutyrates. It may also be used as a hydrogen donor during the dynamic kinetic resolution (DKR) of various diols, monoprotected diols and the protected hydroxy aldehydes.
Uses
Diisobutylcarbinol is used as a fragrance ingredient.
Definition
ChEBI: Diisobutylcarbinol is a secondary alcohol.
Preparation
By catalytic hydrogenation of diisobutyl ketone
Aroma threshold values
Detection: 1.3 ppm
General Description
A colorless liquid. Flash point 162°F. Less dense than water and insoluble in water. Vapors heavier than air.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Diisobutylcarbinol is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
Health Hazard
None expected
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Chemical Reactivity
Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Safety Profile
Moderately toxic by
ingestion and intraperitoneal routes. Mddly
toxic by skin contact. A powerful systemic
irritant by inhalation. A skin and eye irritant.
Can cause central nervous system and liver
damage when ingested. Combustible when
exposed to heat or flame; can react with
oxidizing materials. To fight fire, use alcohol
foam, foam, CO2, dry chemical. When
heated to decomposition it emits acrid
smoke and fumes.
Toxics Screening Level
The initial threshold screening level (ITSL) for 2,6-dimethyl-4-heptanol is 30 μg/m3 annual averaging time.
