Disproportionation and Transalkylation of Alkylbenzenes Over Zeolite Catalysts
Applied Catalysis A: General 181 (1999) 355±398 Disproportionation and transalkylation of alkylbenzenes over zeolite catalysts Tseng-Chang Tsaia, Shang-Bin Liub, Ikai Wangc,* aRe®ning and Manufacturing Research Center, Chinese Petroleum Corporation, Chiayi 600, Taiwan bInstitute of Atomic and Molecular Sciences, Academia Sinica, PO Box 23-166, Taipei 106, Taiwan cDepartment of Chemical Engineering, National Tsing-Hua University, Hsinchu 300, Taiwan Received 13 June 1998; received in revised form 3 October 1998; accepted 5 November 1998 Abstract Disproportionation and transalkylation are important processes for the interconversion of mono-, di-, and tri-alkylbenzenes. In this review, we discuss the recent advances in process technology with special focus on improvements of para-isomer selectivity and catalyst stability. Extensive patent search and discussion on technology development are presented. The key criteria for process development are identi®ed. The working principles of para-isomer selectivity improvements involve the reduction of diffusivity and the inactivation of external surface. In conjunction with the fundamental research, various practical modi®cation aspects particularly the pre-coking and the silica deposition techniques, are extensively reviewed. The impact of para-isomer selective technology on process economics and product recovery strategy is discussed. Furthermore, perspective trends in related research and development are provided. # 1999 Elsevier Science B.V. All rights reserved. Keywords: Disproportionation; Transalkylation; -
Ethylene Glycol
Ethylene glycol Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic Ethylene glycol compound with the formula (CH2OH)2. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, sweet-tasting, viscous liquid.

FOREWORD The Superfund Amendments and Reauthorization Act of 1986 (Public Law 99-499) extended and amended the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCI.A or Superfund). This public law (also known as SARA) directed the Agency for Toxic Substances and Disease Registry (ATSDR) to prepare toxicological profiles for hazardous substances which are most commonly found at facilities on the CERCI.A National Priorities List and which pose the most significant potential threat to human health, as determined by ATSDR and the Environmental Protection Agency (EPA). The list of the 100 most significant hazardous substances was published in the Federal Register on Ap r il 17, 1987. Section 110 (3) of SARA directs the Administrator of ATSDR to prepare a toxicological profile for each substance on the list. Each profile must include the following content: "(A) An examination, summary, and interpretation of available toxicological information and epidemiologic evaluations on a hazardous substance in order to ascertain the levels of significant human exposure for the substance and the associated acute, subacute , and chronic health effects.
