3,5,5-TRIMETHYLHEXANAL Usage And Synthesis

Chemical Properties

3,5,5-Trimethylhexanal has an aldehydic odor.

Uses

3,5,5-Trimethylhexanal was used in preparation of gem-dithiols via reaction with hydrogen sulfide.

Uses

3,5,5-Trimethylhexanal has been suggested for use in perfume compositions as a very powerful masking agent. In extreme dilution, its odor is generally considered pleasant, but the opinion is not unanimous. It has found extensive use as the main active ingredient in various types of masking odors, room fresheners, deodorizers, etc. It is relatively stable against oxidation and polymerization, but it will produce intensely yellow colored condensation products with Anthranilates, darker with Quinolines or Indoles. However, it is rarely used in connection with those materials, more often with alifatic aldehydes, Monoterpenes, Pine fragrance materials, etc.

Definition

ChEBI: 3,5,5-Trimethylhexanal is a fatty aldehyde.

Preparation

From diisobutylene via the oxo reaction.

Flammability and Explosibility

Flammable
