Abstract
This study concerns thermodynamic and kinetic regularities of benzene alkylation with propylene and diisopropylbenzene transalkylation by investigating reaction mechanism. For each step, thermodynamic parameters, such as pre - exponential factor and activation energy were determined. Ab initio approach was used for this purpose. Also effects of solvation and ions formation were taken into account. Finally, comparative analysis of two processes was made.
1. Introduction
1.1 Background
Cumene is an important raw material in petrochemistry to obtain phenol and its co - product – acetone . Usually cumene is produced at the same facility that manufactures phenol. Its synthesis is based on the alkylation of benzene with propylene using a с id catalysts. The main technology now used for cumene producing is a process catalyzed by phosphoric acid loaded on ceyssatite patented by the Universal Oil Products Company (UOP Co.). AlCl3 is also chosen as the catalyst. However, such materials usually introduce various problems such as corrosion, harmful effects on the environment . Some processers used BF3, but it had controlling difficulties in comparison with AlCl, and the BF3 process requires higher temperature and pressure to operate. Since 1965, acid zeolite is of great interest for cumene manufacture, but only recently it has been commercialized by Dow, Mobil, CD Tech, UOP and Enichem. Despite that, zeolite catalysts were widely used because of their safety, easy deactivation by coking, short regeneration cycle, and hard reaction condition became problems. A new type of catalyst for this process – ionic liquids – was developed, but is not commercialized . In spite of new catalysts emergence, process with aluminum chloride stays actual for many cumene producers. It is necessary to increase cumene production, because nowadays demand for cumene rose up to 12 million tons in 2011 and keeps growing.
1 .2 Reaction
The alkylation reaction of benzene with propylene is carried out in the presence of Lewis acids. It is known that alkylation occurs through activation of the olefin by catalyst, and then activated complex react s with benzene and alkylbenzenes.

Conference Alert & Call for Papers: Asian Downstream Week

“Do unto those downstream as you would have those upstream do unto you.” -- Wendell Berry (born August 5, 1934), American novelist, poet, environmental activist, cultural critic, and farmer

A recent email alert describes a new and improved version of an old favorite.  To quote the news release …
///////
Asian Downstream Week 2015 (http://www.downstream-asia.com/) (previously known as Downstream Asia) is expanding. In addition to the established Refining & Petrochemical Asia, 2 new conferences are now incorporated: 
    Petrochem & Refining Operational Excellence Asia
    Petrochem SCM & Logistics Asia
///////

Conference organizers invite you to submit abstracts for the event, scheduled for Singapore from 28 -29 October 2015 as part of Singapore International Energy Week (SIEW), hosted by Singapore Energy Market Authority (EMA).

SIEW, incidentally, is an annual conference concerned with energy issues in the broader sense.  Its concerns include all potential forms of energy, from nuclear to biological and everything in between.

As described on its Web …

///////
The Singapore International Energy Week (SIEW) is an annual week-long platform for energy professionals, policymakers and commentators to discuss and share best practices and solutions within the global energy space.
SIEW aims to facilitate the exchange of ideas and discussions on pertinent energy-related issues, while simultaneously meeting the strategic objectives of Singapore's commitment to becoming a global leading energy hub and "living lab". At the same time, opportunities are set up for networking and deal-making among energy companies converging on the event, as well as to provide a platform to showcase innovative products and solutions in the energy marketplace.

Conference Alert: Aqueous Corrosion


“When it's three o'clock in New York, it's still 1938 in London.” -- Bette Midler (American Singer and Actress, b.1945)

Gordon Research Seminars (GRS) cover a broad range of technology topics.  One of them is on Aqueous Corrosion, scheduled at Colby-Sawyer College, New London, New Hampshire (USA), July 10-15, 2016 (http://www.grc.org/programs.aspx?id=12283). The GRS Web describes the 2014 Aqueous Corrosion Seminar as follows …

///////
2014 Aqueous Corrosion GRC
The main objectives of corrosion science and engineering are to reduce the risk to society from corrosion, improve the sustainability of engineered systems, and assist in the conservation of our cultural heritage. The need to understand and reduce corrosion is more urgent than ever due to aging of systems important to maintaining the modern society and the rapid expansion of industrial infrastructure in the developing countries. Corrosion science and engineering are highly interdisciplinary, requiring tools and techniques developed in other fields such as surface science, materials science, mechanics, electrochemistry, biochemistry, etc. The availability of improved tools in other related fields has enabled us to gain better insights into corrosion processes. However, there is an increasing need to integrate this knowledge for predicting corrosion risk.

The 2014 Aqueous Corrosion GRC will contain talks from leading researchers on multi-scale modeling techniques to predict corrosion, in-situ analytical techniques to understand fundamental corrosion processes, mechanisms of localized corrosion and environmentally assisted cracking, and microbiological processes at the electrochemical interface. The conference will conclude by discussing the major theme of the conference: assessing and reducing corrosion risk. An important goal of this GRC is to bring about a dialog between academic, government, and industrial researchers. The conference intends to have presentations in the traditional GRC format (i.e. 40 minute talk plus 20 minute discussion). Informal discussions and poster sessions in the evenings will complement these interactions.
https://www.grc.org/programs.aspx?id=12282

TIP: Bookmark the GRS site and visit it once or twice a year.  Most of the conferences will not interest you, but the occasional one will be spot on.
