“…The decrease of dimers occurred in favor of trimers (trimer-1 and trimer-2) because trimers are formed from dimers by consecutive reactions. These results are in agreement with those reported in the literature [31,32]. Contrary to the selectivity of trimers, that of tetramers decreased with increasing temperature due to cracking reactions which occurred at higher temperatures.…”

Natural Kaolin Clay was calcined and treated by sulfuric acid. The resulting solid acid catalyst was characterized by FTIR, TGA, and X-ray powder diffraction (XRD) and tested for isobutene oligomerization in a gas phase. The characterization results showed that the acid treated clay underwent chemical and structural transformations. After acid treatment, the Si/Al ratio was increased, and the crystalline raw clay became amorphous. The effects of various parameters such as reaction temperature, reaction time and contact time on isobutene oligomerization were investigated. Catalytic tests showed that isobutene oligomerization led to dimers and trimers as major products. Tetramers were obtained as byproducts. At relatively high reaction temperatures and long contact times, the conversion was enhanced while the selectivity of dimers was decreased in favor of higher oligomers.

“…It was found that the carrier played a key role in the reaction route. Among these SILCs, silica supported chloroaluminate IL was highly efficient for this reaction . Although the procedure to prepare SILCs by incipient wetness impregnation is very simple and convenient, the ILs can sometimes destroy the pore structure of the supports and significant leaching of the IL was observed in the liquid‐phase reactions …”

Ionic liquids (ILs) have attracted much attention due to their unique properties and wide application potential in a variety of fields. The unusual properties of ILs provide numerous opportunities to design and prepare arious advanced materials, including highly efficient catalysts. In recent years, synthesis of different kinds of catalytic materials and their applications in chemical reactions have been studied extensively and have become a very interesting area. Herein, we present a review on the synthesis of catalytic materials using ILs as the media and/or functional components; the important and widely investigated topics are discussed, including mainly metal nanocatalysts/IL, functional IL/support, metals or metal oxides/IL/support, polymeric ILs (PILs) catalysts, and the performances of catalytic systems are highlighted. An outlook for this interesting area is also given at the end of the article.

“…Supported chloroaluminate ILs were used for the trimerization of isobutene in a feed contaning C 4 mixture. [70] Both the support and immobilization methodology were found to play a crucial role in the reaction. Catalysts obtained by mixing the IL with the silica support showed excellent oligomerization activity.…”
