Oligoalkylnaphthenic (C<sub>6</sub>-C<sub>12</sub>) Oils Obtained in the Presence of Ti-Containing Ionic-Liquid Catalysts

引用

Green and Sustainable Chemistry 2013年第4期3卷 18-26页

作者： Akif Hamid Azizov Reyhan valy Aliyeva Khayala Haydar Asgerova The Y.H. Mamedaliyev Institute of Petrochemical Processes of Azerbaijan National Academy of Sciences Baku Azerbaijan

In this present paper, the result of C6-C12 α-olefins oligomerizaton in the presence of recyclable chloroaluminate type ionic-liquid catalysts and their combination with Ti-containing complexes is presented. By different methods of analysis the composition and structure of oligoalkylnaphtenic products obtained in the presence of ionic-liquid catalysts and Ti-containing modifiers have been studied.

引用

一带一路报道(中英文) 2022年第1期 19-19页

作者： valy Vetsaphong the Lao National Chamber of Commerce and Industry

The streamlined bullet train, or electric multiple unit (EMU)train for the China-Laos Railway, arrived at the newlybuilt Vientiane station on Oct 16. The outlook, especially the roof, is Lao style, and the decoration embodies Lao and Chinese cultures, conforms to the characteristics of the China-Laos Railway. The stations are nicely built.
