Отримання й хімія
Спосіб отримання
Hexyl cinnamaldehyde is typically produced via crossed-aldol condensation of octanal and benzaldehyde. The temperature of the condensation is not critical and is in practice often between 50° and 100° C, preferably between 75° and 95° C, in particular between 80° and 90° C. With pyrrolidine as catalyst, relatively little alpha-hexyldecenal, the aldol condensation product of octanal, is formed. Alpha-hexyldecenal cannot easily be separated from hexylcinnamaldehyde by distillation and impairs the quality of the odour. In one example of the patent, the organic phase was distilled under reduced pressure, and redistillation of the main fraction under reduced pressure gave hexylcinnamaldehyde of olfactory quality with a purity above 99%.
