云南师范大学化学化工学院有机化学课件Chapter10 Alcohols and Phenols
Rotational reorientationtimes (TROT)were obtained for rhodamine B in a series of n-alcoholsand polyalcohols of varying viscositiesby a transient grating technique. The general trend of the Debye-Stoke...
A mesoporous MCM-41 molecular sieve material with a molar ratio of SiO2/Al2O3 = 70 and loaded with H3PO4 was used as a catalyst for the alkylation of toluene, using various alcohols, namely methanol, ...
A light-scattering sensor that incorporated zinc oxide (ZnO) nanoparticles was developed and characterized in this study. Evenly distributed nanostructured ZnO materials were formed on the sensing ele...
Primary and secondary alcohols were transformed in high yield to corresponding iodides by 4-chloro-3,5-dioxaphosphacyclohepta [2,1-a; 3,4-a'] dinaphthalene (BINOL-PCl) at room temperature. The tertiar...
Sugars and sugar-alcohols are demonstrated to be important constituents of the ambient aerosol water-soluble organic carbon fraction, and to be tracers for primary biological aerosol particles (PBAP)....
Aqueous Media Oxidation of Alcohols with Ammonium Persulfate     oxidation  lcohol  queous medi  mmonium persulfate       font style='font-size:12px;'> 2007/12/19
摘要 Oxidation of series of various primary and secondary alcohols to corresponding carbonyl compounds with ammonium persulfate in aqueous media was described. No over oxidation of primary alcohols to c...
In this review article, some of the challenging research areas related to the development of novel catalysts and catalytic processes for the chemical fixation of CO2 by converting it to alcohols and e...
专著信息 书名 ”Fourier transform NIR study of liquid diffusion processes in Nylon 11 films: Comparison of water with alcohols” 语种 英文 撰写或编译 作者 Peiyi Wu,H. W. Siesler 第一作者单位 出版社 CHEMISTRY OF MATERIALS 15 (14)...
Alcohols and phenols were tetrahydropyranylated in the presence of 2,4,6-trichloro[1,3,5]triazine in good to excellent yields in acetonitrile.
Alkyl isocyanates are prepared in good to excellent yields by treatment of alcohols, thiols, and trimethylsilyl ethers with 2,4,6-trichloro[1,3,5] triazine/n-Bu4NOCN in acetonitrile. This method is hi...
In cyclohexane, thirteen examples of primary and secondary aliphatic alcohols were easily converted to the corresponding acetate derivatives within a short time, ranging from 5 min to 2.5 h, and in go...
A new efficient and cost-effective method for the preparation of 1,2-amino alcohols is described. The reactions of amino acids with NaBH4 in the presence of NiCl2 or MoO3 in water give 1,2-amino alcoh...
The large amount of water in the interlamellar space of alkylammonium montmorillonites in aqueous solutions is not fixed by intercalated hexanol or octanol. The hydration of the NH3+-group and the fil...
The reaction of 2-methyl pent-2-ene with primary alcohols (C1-C18) at 95°C over an Al-montmorillonite gave yields of 20–90% of ethers of the type R-O-C(CH3)2C3H7. Lower yields were produced if seconda...
