title: Formation of odorous compounds from hydrogen sulphide and 2-butenal.
abstract: Strongly odorous compounds may be formed upon addition of hydrogen sulphide to unsaturated carbonyl compounds. The reaction between hydrogen sulphide and 2-butenal was studied, and the characteristics of the flavour, the structure and some of the physical chemical characteristics of the reaction products were determined. The influence of the pH on the type of components formed in dilute aqueous solution was investigated.
