An, Shunyong published the artcileSynthesis optimization and kinetics for ketalization of cyclohexanone with ethylene glycol in a zeolite membrane reactor, HPLC of Formula: 177-10-6, the publication is Shiyou Xuebao, Shiyou Jiagong (2014), 30(3), 527-535, database is CAplus.

Ketalization of cyclohexanone with ethylene glycol was investigated in a pervaporation (PV) membrane reactor by using high-flux zeolite T membrane and zeolite H-β catalyst. A kinetic model was built for the PV-aided ketalization based on the assumption of second-order reaction, and the exptl. data were compared with the model predictions. The molar ratio of cyclohexanone to ethylene glycol and catalyst amount for the reaction occurring in membrane reactor were optimized, meanwhile, the reusability of zeolite T membrane and the solid catalyst in the ketalization were investigated. The conversion of cyclohexanone increased from 64.3% to almost completion due to water removal from the reaction system by the aid of PV process. The reaction could be carried out under the close theor. ratios of reagents, so that the reaction atom economy was enhanced. Zeolite T membrane was stable in reaction mixture and showed a good reusability for the reaction.

Chen, Wan-Ting published the artcileCo-liquefaction of swine manure and mixed-culture algal biomass from a wastewater treatment system to produce bio-crude oil, Synthetic Route of 177-10-6, the publication is Applied Energy (2014), 209-216, database is CAplus.

This study explored the feasibility of combining two types of feedstocks, swine manure (SW) and mixed-culture algae (AW) from wastewater treatment systems, for bio-crude oil production via hydrothermal liquefaction. The effect of feedstock combination ratios on the bio-crude oil yields and qualities were investigated. SW to AW ratios (dry weight basis) were 1:3, 1:1 and 3:1 with a total solids content of 25%. Pure SW and AW were also hydrothermally converted at the same reaction condition for comparison. By combining 75% SW with 25% AW, the highest bio-crude oil yield was achieved (35.7% based on dry matter). By mixing 25% SW with 75% AW, the highest heating value (27.5 MJ/kg) was obtained. GC-MS spectra and thermal gravimetric anal. of bio-crude oils revealed that both light oils and heavy crude were produced, averaging 25% and 20% of the bio-crude oil, resp. Anal. of energy consumption ratios indicated that co-liquefaction of AW and SW is energetically feasible and could be an economically competitive system for bio-crude oil production

Dai, Liming published the artcileEnhanced ketalization activity of cyclohexanone and ethanediol over immobilized ionic liquid in mesoporous materials, Computed Properties of 177-10-6, the publication is Korean Journal of Chemical Engineering (2017), 34(5), 1358-1365, database is CAplus.

Three different mesoporous mol. sieves, including MCM-41, MCM-48, and SBA-15, were synthesized by hydrothermal process and characterized by XRD, BET and TEM. The chlorine-aluminate acidic ionic liquid of 1-butyl-3-methylimidazolium chloride-aluminum chloride ([Bmim]Cl-AlCl₃, denoted as Al-ILs) was prepared by two-step method. The immobilized ionic liquid (SBA-15/Al-ILs, MCM-41/Al-ILs, MCM-48/Al-ILs) was prepared through impregnating Al-ILs. The structures of composite catalysts were characterized by XRD, BET, FT-IR, TEM and XPS. The amounts of aluminum present in the resulting composite catalysts were detected by ICP-AES to calculate the amount of AL-ILs impregnated. The ketalization between cyclohexanone and ethanediol was used as the model reaction to test the catalytic activities of the composite catalysts. The effects of molar ratio of the reactants, reaction time, the catalyst dose, as well as the addition of cyclohexane were discussed in detail. Also, catalytic activities of three catalysts with different pore sizes were compared. Under comparable conditions, the SBA-15/Al-ILs composite catalyst exhibited much high catalytic activity and gave a maximum yield that was ca. 85.1%.

Xie, Yingjie published the artcileB-SBA-16 encaged functional tungstosilicic acid type ionic liquids to catalyze the ketal reaction, Product Details of C8H14O2, the publication is Dalton Transactions (2019), 48(45), 17106-17116, database is CAplus and MEDLINE.

There is special significance to composite catalysts using SBA-16 nano-cages as carriers in the acid catalysis field. A method for embedding boron atoms onto SBA-16 to increase acidic sites and enhance the acidity of the nano-cages was described. The tungstosilicic acid type ionic liquid (SWIL) was encaged into B-SBA-16 acidic nano-cages to obtain various composite catalysts. The acidic nano-cages and composite catalysts were characterized by FT-IR, TG/DSC, SAXD, BET, SEM, TEM, XPS and ¹H NMR analyses. Research confirmed that boron was embedded onto the SBA-16 nano-cages in varying proportions and the obtained B-SBA-16 acidic nano-cages still maintained a high degree of pore ordering. The SWIL was successfully encapsulated into the acidic nano-cages via the immersion method. The cage-encapsulated tungstosilicic acid type ionic liquid catalysts SWIL/B(n)-SBA-16 were applied to catalyze the ketal reaction of cyclohexanone (CYC) with ethylene glycol (EG). The results showed that the conversion of CYC could reach 92.01% along with the yield of cyclohexanone ethylene glycol ketal (CGK) of 83.87% under ideal conditions. The CYC conversion was still nearly 86.86% and the CGK yield was 69.50% even after 8 times of continuous reuse.

Li, Zhang-Min published the artcileMOR zeolite supported Bronsted acidic ionic liquid: an efficient and recyclable heterogeneous catalyst for ketalization, Quality Control of 177-10-6, the publication is RSC Advances (2014), 4(24), 12160-12167, database is CAplus.

In order to widen the application of ionic liquids as efficient and renewable heterogeneous catalysts, supported ionic liquids (SILs) have received considerable attention. A novel heterogeneous catalyst MOR zeolite supported Bronsted acidic ionic liquid (BAIL@MOR) was therefore prepared, characterized and applied in the ketalization reaction. The influences of reaction temperature, time, and catalyst loading have also been investigated in detail. Combined characterization results of XRD, FT-IR, SEM, TG-DTG and N₂ adsorption-desorption suggested that the BAIL [CPES-BSIM][HSO₄] was successfully immobilized on the surface of MOR zeolite by covalent bonds. Moreover, the catalytic performance tests demonstrated that the catalyst BAIL@MOR exhibited excellent catalytic activities in the ketalization of cyclohexanone with glycol, 1,2-propylene glycol and 1,3-butylene glycol under mild reaction conditions, as comparable with the homogeneous catalysis of the precursors [BSmim][HSO₄] and H₂SO₄. In addition, the catalyst BAIL@MOR was also found to be reusable five times without a significant loss of its catalytic activity. Thus, the heterogeneous catalyst BAIL@MOR can act as a promising candidate for the ketalization reaction.

Compound 1 has a stable 3D organic-inorganic hybrid framework. It was used as a catalyst for carbonyl-protection. The synthesis of cyclohexanone ethylene ketal was performed as an example to investigate some influence factors on the yield, such as catalyst loading, molar ratio of reactants and reaction time. The optimal conditions are: the molar ratio of catalyst (based on Mo) to ketone is 1:300, the molar ratio of ketone to alc. is 1:1.4, and reaction time is 2.5 h. The catalytic activity of compound 1 for the synthesis of four other ketals was evaluated. The results show that compound 1 is a better catalyst for the synthesis of cyclohexanone ethylene ketal.
