2,4,6-Octatrienal synthesis

12synthesis methods
-

Yield:-

Reaction Conditions:

sulfuric acid in water; pH=~ 3.8 at 20 - 25; for 12 - 72 h;Conversion of starting material;light protected;

Steps:

1; 3
4 ml of aqueous salt solutions (see tables) continuously stirred and protected from light.Reactant concentration: Acetaldehyde: 0. 1 - 0.5 M; acetone: 0.5 - 1 M. Temperature = 25 C (room T) or 35 C.The degree of conversion of the reaction was determined by measuring the consumption of reactant, for acetone, and the formation of the products, for acetaldehyde by UV-visible absorption: acetone monitored at 269 nm, acetaldehyde product (2,4,6-octatrienal) monitored at 320 and 350 nm.
