Spherical melamine-formaldehyde resin (MFR) particles were synthesized using the condensation reaction of melamine and formaldehyde with PEG-2000 as an additive. After thermal treatment at 200°C and then sulfonation by chlorosulphuric acid, an MFR-supported strong acid catalyst (SMFR) was prepared with an acidity of 3.23 mmol g^-1. This new acid catalyst was evaluated in the reactions of esterification and acetalization, with the results indicating that this novel acid catalyst was highly efficient in the traditional acid-catalyzed reaction. Its high activity, stability and reusability give it great potential for “green” chem. processes.

A SO₃H-bearing nanofiber mat was synthesized and investigated as a novel heterogeneous acid catalyst. Preoxidated polyacrylonitrile nanofiber mat was prepared via electrospinning and heat treatment, and then reacted with chlorosulfuric acid to introduce the sulfonic groups. The nanofiber mat owned high acidity of 2.99 mmol/g. The preoxidation and sulfonation were examined by FT-IR spectroscopy, elemental anal. and X-ray diffraction spectroscopy (XRD). The fiber morphologies were characterized by SEM (SEM). The catalytic activities and reuse of the prepared nanofiber mat solid acid catalyst have been evaluated for the acetalization and esterification. The regular fiber mat structure could significantly facilitate the recovery and reuse of the catalyst. The excellent catalytic performance and easy recycling made the novel fiber mat solid acid hold great potential for the green chem. processes.

Du, Yijun published the artcilePreparation of a novel solid acid catalyst with Lewis and Bronsted acid sites and its application in acetalization, Safety of 1,4-Dioxaspiro[4.5]decane, the publication is Turkish Journal of Chemistry (2014), 38(1), 157-163, database is CAplus.

A novel melamine-formaldehyde resin (MFR) supported solid acid with Lewis and Bronsted acid sites was synthesized through the immobilization of acidic ionic liquid and cuprous ion on MFR. The SEM (SEM) characterization showed that addition of PEG-2000 in the synthesis of MFR could promote the formation of regular particles with diameters around 3.7 μm. The XRD pattern demonstrated that some cuprous ions were aggregated. The catalytic performance of this acid catalyst was evaluated by acetalization. The results showed that the catalytic activity of MFR with Bronsted acid could be improved by addition of Lewis acid. The solid acid was very efficient for the acetalization of carbonyl compounds and diols with moderate to excellent yields and there was no loss of catalytic activity even after being recycled for 6 runs.

Chandrasekhar, Sosale published the artcileChloral Hydrate as a Water Carrier for the Efficient Deprotection of Acetals, Dithioacetals, and Tetrahydropyranyl Ethers in Organic Solvents, SDS of cas: 177-10-6, the publication is Synthetic Communications (2014), 44(13), 1904-1913, database is CAplus.

The efficient deprotection of several acetals, dithioacetals, and tetrahydropyranyl (THP) ethers under ambient conditions, using chloral hydrate in hexane, is described. Excellent yields were realized for a wide range of both aliphatic and aromatic substrates. The method is characterized by mild conditions (room temperatures or below), simple workup, and the ready availability of chloral hydrate. High chemoselectivity was also observed in the deprotection, acetonides, esters, and amides being unaffected under the reaction conditions. Products were generally purified chromatog. and identified spectrally. These results constitute a novel addition to current methodol. involving a widely employed deprotection tactic in organic synthesis. It seems likely that the mechanism of the reaction involves adsorption of the substrate on the surface of the sparingly soluble chloral hydrate.

Li, Ruiyun published the artcileEfficient and reusable SBA-15-immobilized Bronsted acidic ionic liquid for the ketalization of cyclohexanone with glycol, Synthetic Route of 177-10-6, the publication is RSC Advances (2018), 8(13), 7179-7185, database is CAplus and MEDLINE.

Ketalization of cyclohexanone with glycol has been carried out using mol. sieve SBA-15 immobilized Bronsted acidic ionic liquid catalyst. The properties of the heterogeneous catalysts were characterized by elemental anal., Fourier transform IR spectra, SEM, thermogravimetry/differential scanning calorimetry, and N₂ adsorption-desorption. The results suggested that Bronsted acidic ionic liquid [BSmim][HSO₄] had been successfully immobilized on the surface of SBA-15 and the catalytic performance evaluation demonstrated that the catalyst BAIL@SBA-15 exhibited excellent catalytic activities in the ketalization of cyclohexanone with glycol. In addition, the effects of reaction temperature, catalyst loading, reaction time, and reactant molar ratio have also been investigated in detail, and a general reaction mechanism for the ketalization of cyclohexanone with glycol was given. The SBA-15 immobilized ionic liquid can be recovered easily and after reusing for 5 times in the ketalization reaction, the catalyst could still give satisfactory catalytic activity.

A completely regioselective and challenging gold(I)-catalyzed ring-opening of cyclic 1,3-dioxolanes and dioxanes by trimethylsilyl alkynes to set diol-derived propargyl trimethylsilyl bis-ethers is reported. This unprecedented and not trivial transformation does not operate with the catalytic methodologies recently reported for catalytic alkynylation of acyclic acetals/ketals, and is uniquely enabled by the application of a recently introduced synergistic gold(I)-silicon catalysis concept capable of producing simultaneously catalytic amounts of two key players, a silicon-based Lewis superacid and a nucleophilic gold acetylide.

Patel, Rajani published the artcileGas chromatography-mass spectrometry analysis of chemical components of two different stages of root part of moolak (Raphanus sativus Linn.), SDS of cas: 177-10-6, the publication is International Journal of Research in Ayurveda & Pharmacy (2021), 12(2), 11-14, database is CAplus.

Moolak or Radish (Raphanus sativus Linn.) is grown all over the world. Radish is eaten raw as salad due to its pungent flavor. Tender radish root is consumed with leafy vegetable and radish in its starting stage of bolting is consumed as stew. After late bolting stage, only new leaves produced in inflorescence axis and seeds are consumed as edible substance and mature seeds are used for medicinal purpose like Kushtha (Skin disease). Formulations of Moolak seed is already mentioned in Ayurvedic literatures. Here we are taking tender and early bolt stage of radish where tender is balmoolak and Bolt is vriddha moolak. This study shows the differences in chem. composition of two stages of moolak to know about their medicinal properties, because medicinal properties of herbs are due to phytoconstituents. GC-MS (Gas chromatog.-mass spectrometry) technique is used to identify bioactive compounds in methanolic extract of Raphanus sativus. Tender radish (balmoolak) has shown total 38 peaks and Bolt radish (vriddhamoolak) showed total 41 peaks of phytoconstituents. 15 compounds are common among both samples.
