Separation of diisopropylnaphthalene isomers

Identification of suspected hazardous chemical contaminants in recycled pastry packaging

“…In this regard, diisopropylnaphtalenes posed a challenge to the experiment, since up to 10 diisopropylnaphthalenes can theoretically be obtained during synthesis; therefore separation is a crucial issue for the selective identification of each one. (Bouvier et al, 2009). However, separation of all DiPN isomers is neither within the scope of this study nor within the abilities of routine benchtop GC-MS instruments.…”

Comments on “Shape-selective diisopropylation of naphthalene in H-mordenite: Myth or reality?”

“…The experimental treatment of this complex reaction system stirred much controversy in recent years, especially because of the ambiguity in the analysis of the reacting mixture [2]. A continuous improvement in the analytical method changed or at least modified the interpretation of the experimental findings [3]. In the paper, being commented the analytical technique was superb; thus, no one has any reason to doubt the validity of the experimental results obtained.…”

Synthesis of modified catalyst and stabilization of CuO/NH4‐ZSM‐5 for conversion of methanol to gasoline

“…Since then, many actions have been taken to improve this process and many parameters have been improved in this process. These modifications were performed in reactor design, feedstock conditions and catalyst modification using metal oxide such as copper oxide . The main aim of the present investigation is to study the effect of CuO loading on NH 4 ‐ZSM‐5 support for conversion of methanol to gasoline range hydrocarbons.…”

“…These modifications were performed in reactor design, feedstock conditions and catalyst modification using metal oxide such as copper oxide. [17][18][19][20][21][22][23][24][25] The main aim of the present investigation is to study the effect of CuO loading on NH 4 -ZSM-5 support for conversion of methanol to gasoline range hydrocarbons. A series of CuO/ NH 4 -ZSM-5 catalysts were prepared, characterized, and experimented for their performance on methanol conversion and hydrocarbon yield.…”
