2-Hexenal, 2-propyl-, also known as 2-hexenal, 2-propyl-, is an organic compound with the chemical formula C9H16O. It is a colorless to pale yellow liquid with a strong, green, and herbaceous odor. This aldehyde is a member of the alkenal family and is characterized by the presence of a carbon-carbon double bond and an aldehyde functional group. It is commonly used as a flavoring agent and fragrance compound in the food and perfume industries, providing a fresh, green, and leafy scent. 2-Hexenal, 2-propyl- can be synthesized through various chemical reactions, such as the oxidation of 2-propyl-1-hexanol or the condensation of propionaldehyde with 2-butenal. Due to its reactive nature, it is sensitive to light, heat, and air exposure, and should be stored under controlled conditions to maintain its stability and quality.

688-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 688-83-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 688-83:
(5*6)+(4*8)+(3*8)+(2*8)+(1*3)=105
105 % 10 = 5
So 688-83-5 is a valid CAS Registry Number.

Method for Carrying Out Multiphase Aldol Condensation Reactions to Give Mixed a, beta-Unsaturated Aldehydes

-

Paragraph 0058-0061, (2014/02/15)

The invention relates to a continuous method for carrying out a multiphase aldol condensation reaction to obtain mixed α, β-unsaturated aldehydes by reacting a mixture of two aliphatic aldehydes having different numbers of carbon atoms, i.e. 2 to 5, in the molecule in a vertical tubular reactor in a concurrent flow in the presence of an aqueous solution of a basically reacting compound. In said method, the aldehyde mixture is dispersed in the aqueous phase in the form of drops, and the aqueous solution of the basically reacting compound flows through the tubular reactor as a continuous phase in laminar conditions.
