Acetophenone glycerol ketal

Acetophenone Glycerol Ketal (CAS: 4361-60-8) is a 1,3-dioxolane derivative constructed via the condensation of acetophenone and glycerol. Its molecular structure incorporates a stable ketal ring and active hydroxyl functional groups, exhibiting superior chemical stability and a gentle sensory profile.

Within high-end pharmaceutical and personal care supply chains, this product is extensively employed as a specialized fixative and modifier for premium fragrances. It effectively prolongs aroma longevity and imparts distinct rose and honey base notes to formulations. Furthermore, as a critical protecting group building block in chiral drug synthesis, it holds significant application value in the specialty chemicals sector.

Product specifications feature an assay ≥ 99.0% (GC), appearing as a colorless to pale yellow transparent oily liquid. Conventional ketal products on the market typically rely on traditional large-batch production processes. Due to prolonged heat exposure and uneven mass transfer efficiency, these methods are prone to thermal degradation side reactions of glycerol, generating acrolein-type impurities with pungent odors. This results in common quality defects such as product yellowing, suboptimal sensory purity, and batch-to-batch impurity fluctuations.

Through fundamental process re-engineering, we have adopted a design philosophy combining ultra-short heat history control with an instantaneous vacuum stripping system. By precisely controlling material residence time in high-temperature zones, we kinetically suppress byproduct formation pathways. Coupled with efficient deep pressure differential dynamic equilibrium intervention technology, we achieve deep conversion at the reaction level and real-time impurity removal.
