For purposes of comparison, the respective reactions of perfluoro-2-methyl-oxolane (la), perfluoro-2-n-butyloxolane (7a), and perfluoro-2, 5-dimethyloxolane (8a) with AlCl3 were also conducted. An increasingly higher reaction temperature was needed for the reaction of A with AlCl3 to give B...
Reactions of ortho- and meta-xylenes with tert.-butyl chloride in presence of anhydrous AlCl3 as catalyst have been studied. Effects of variation of temperatue, molar ratio of xylene to tert.-butyl chloride, amount of catalyst and reaction time on the reactions have been investigated.关键词: ...

catalysts that support the various applications. These generally include Lewis acids (AlCl3, FeCL3) or protic Brønsted acids (HF, H2SO4,etc.), as well as solid lattice structures, such as acidic cation exchange resins, anhydrous acid-exchanged zeolites and carbon based materials, such as ...
(2\'-hydroxy-3\'-chloroacetyl-5\'-methylphenyl)benzotriazole(HCAMPBZ)was synthesized from 2-(2\'-hydroxy-5\'-methylphenyl)benoztriazole(UV-P)and chloroacetyl chloride by esterification and Fries rearrangement reaction with presence of nitrobenzene as solvent and anhydrous aluminium chloride as ...
the highest graft ratio reaches up to 29%,but when mass fraction of anhydrous AlCl3 is over 3%,the graft ratio declines,PVC begins degradation and produces olefinic bonds.Research results demonstrate that microwave irradiation is an effective way of realizing Friedel-Crafts reaction grafting of ...
1,2-Aceanthrylenedione was synthesized through the acylation reaction of anthracene and oxalyl chloride catalyzed by anhydrous AlCl3. 研究了以高活性Lewis酸无水三氯化铝(AlCl3)为催化剂,蒽和草酰氯为反应物合成1,2-蒽乙二酮的酰基化反应。 2. 2-(4'-methylbenzoyl) benzoic acid (MBBA) was synthesized...
