Effects of the molar ratio of ketone or aldehyde to dihydric alcs., H₃PW₆Mo₆O₄₀/MCM-41 catalyst dosage and reaction time on the yield of acetals and ketals were discussed. The results showed that the appropriate conditions were the molar ratio of ketone or aldehyde to dihydric alcs. 1:1.5, the mass ratio of the catalyst to the reactant 0.2% and reaction time 45 min. Under the conditions, the yield of acetals and ketals was 46.8%-88.5%.

The main components of a sample apple fragrance based on membrane-volatilizing craft were analyzed by gas chromatog.-mass spectrometry (GC-MS) methods and compared with that of based on evaporating fiber wick craft, a kind of liquid air fresheners. The volatilization experiment showed that the former craft could keep the perfume volatilization in a more stable and line-type state than the later one. The differences of their craft mainly results from the differences of their fragrance formula. As far as the membrane-volatilizing perfume formula was considered, the components with better membrane-volatilizing characteristics reached to 48.59%, and the rest composed of those with common membrane-volatilizing characteristics (40.95%) and stabilization agent (10%). But there was only 6.31% of the components belonged to good membrane-volatilizing characteristics for evaporating fiber wick craft. So, to develop a fragrance production based on the membrane-volatilizing craft, it was the key to select some components with better membrane volatility.

A practical method for the conversion of 1,2-disubstituted cyclopropanol derivatives obtained by a a Kulinkovich cyclopropanation into linear enones was developed. The approach features regioselective cleavage of the cyclopropane rings in EtOH at ambient temperature with inexpensive and readily available bis(acetylacetonate)cobalt [Co(acac)₂] as a catalyst and air as a reagent. The crude intermediate peroxides were directly reduced with Ph₃P to afford the corresponding β-hydroxy ketones, which, on mesylation and β-elimination performed in a one-pot manner, furnished the end products in good to excellent yields after only one chromatog. step at the end of the whole sequence. The synthesis of the target compounds was achieved using (1R,2R)-rel-2-[2-[[(1,1-dimethylethyl)dimethylsilyl]oxy]ethyl]-1-(methyl)cyclopropanol and related compounds as key reactants.

A convenient method for the deprotection of acetals and ketals was achieved using an imidazolium based protic ionic liquid as a catalyst in aqueous medium via the dual activation of dioxolane. The protocol is highly efficient towards the deprotection of acyclic and cyclic acetals, ketals, benzylidene acetals and tetrahydropyranyl (THP) ethers, giving excellent yields. Functional groups such as tert-Bu ester, tert-Bu di-Me silyl (TBDMS), N-tert-butyloxycarbonyl (N-Boc), and double bond, mesyl, nitro, and glycosidic linkage were tolerated under the benign reaction conditions. Selective deprotection of the 5,6-isopropylidene moiety in 1,2:5,6-di-O-isopropylidene hexose and 3,5-cyclohexylidene moiety in pentose derivatives proceeded smoothly without affecting the 1,2-protected group. The attractive features of this new protocol are the use of mild reaction conditions, tolerance of a wide range of functional groups, use of relatively non-toxic solvent systems and recyclability of the ionic liquid catalyst.

The catalysts of 12-tungstophosphoric acid/SBA-15 with different loading capacity were prepared by in-situ method. The structure and properties of the catalysts were characterized by means of FTIR spectroscopy, TEM, X-ray diffraction, ³¹PNMR and N₂ adsorption-desorption. The results showed that, when the loading capacity was within the lower range, the catalysts retained the long range order structure of the SBA-15 material. With the increase of loading capacity, the aperture and sp. surface area decreased with the increase of loading capacity. However, the structure of SBA-15 was destroyed in some degree when the loading capacity was up to 33.3%. The 12-tungstophosphoric acid highly dispersed in the hole of SBA-15 still kept the Keggin structure, and had certain chem. interaction with the surface hydroxy of SBA-15. The catalytic properties in the synthesis of fructone showed that HPW/SBA-15 catalyst had high catalytic activity and selectivity, and showed excellent reusability.

A series of 12-phosphotungstic acid (PW) and its cesium salt catalysts immobilized on various supports such as ultra-stable Y zeolite (USY), dealuminated USY (DUSY), SiO₂ and SBA-15 were prepared Their sp. surface area and acid strength were measured, and their catalytic performance was evaluated in the synthesis of fructone by acetalization of Et acetoacetate with ethylene glycol. The high catalytic activity was found over the prepared supported heteropoly compound catalysts in this reaction. However, for the supported PW catalysts, a severe leaching of heteropoly anions into water was observed, leading to their poor reusability. By contrast, the Cs salt of PW catalyst supported on DUSY exhibited very high catalytic activity with high water tolerance and reusability. The conversion of Et acetoacetate of 98.7% with the selectivity of fructone above 97% could be obtained over 30% Cs_2.5H_0.5 PW/DUSY under the optimal reaction conditions.
