Description

General description

Diacetin is a volatile acetylated glycerol used as a flavoring agent in e-cigarettes. It is also found in floral oil secreting plants, where it is reported to act as a signal for oil-collecting bees to locate these plants, thus playing a key role in pollination.

Application

• Organ-specific volatiles from Sonoran desert Krameria flowers as potential signals for oil-collecting bees.: This study identifies specific volatile compounds, including Diacetin, emitted by Krameria flowers. These volatiles act as signals for oil-collecting bees, suggesting a specialized ecological interaction (Balbuena et al., 2024, Phytochemistry).


• Techno-Economic Assessment and Sensitivity Analysis of Glycerol Valorization to Biofuel Additives via Esterification.: This paper examines the economic viability of producing biofuel additives, including Diacetin, through the esterification of glycerol, highlighting the process′s potential for cost-effective biofuel production (Pandit et al., 2023, Industrial & Engineering Chemistry Research).
