The Table of Contents on the previous page has been set up to aid the user in quickly locating information on a particular topic. Main topics with an * next to the name denote that this section contains a more detailed table of contents to further aid the user in locating specific help within that section. EVERYONE: It is strongly suggested you use the QUICK START section to properly install the program and its independent supporting programs. More detailed step by step installation instructions are located in Section 3.1 should the user require them. The program has some ―quarks‖ which are explained in the FAQ section. Reviewing theses two sections will save the user much time and frustration. It is critical that all users understand the objectives and limitations of the program and how these might relate to your specific site objectives and goals. This information is presented in the introduction section of this guide (pages 11 through 14). The user, both experienced and inexperienced, will also benefit from reviewing the programs block flow diagram located in section 2. Sections 2.1 gives a one page overview of the entire program flow with links to four one page sub-routine block flow charts. Section 2.6 presents the entire program block flow with one to 2 sentence explanations of each block After that, even the user knowledgeable in process safety evaluations, will benefit from reading the STRATEGY section. Each strategy sub-section is a detailed how-to guide for the key program inputs. Look for the following icons that call out helpful suggestions or common mistakes Copyright © 2012 AIChE P a g e | 3 RMT Help Guide v1.0 January 2012 PROCESS SAFETY NOVICES: For those new to process safety evaluation, the STEP BY STEP INSTRUCTIONS in section 3 are laid out such that the user is taken through the program screen by screen with detailed information on the data required for each screen and how to obtain it. Finally the WORKED EXAMPLES sections present detailed examples with screen by screen instructions from data entry through evaluation and report generation. The novice would be well advised to make full use of this section to practice process hazard evaluation.

  • Efficient Asymmetric Addition of Diethylzinc to Ketones Using Tartaric Acid Derivative As Chiral Ligand
    General Papers ARKIVOC 2008 (ii) 25-32 Efficient asymmetric addition of diethylzinc to ketones using tartaric acid derivative as chiral ligand Ailing Hui,a Jintang Zhang,b Huayin Sun,b and Zhiyong Wangb* aEngineering Research Center of Bio-process (Hefei University of Techonology), Ministry of Education, 193 Tunxi Road, Hefei, Anhui 230009, PRC bDepartment of Chemistry, University of Science & Technology of China, 96 Jinzhai Road, Hefei, Anhui 230026, PRC E-mail: [email protected] Abstract A new chiral ligand derived from natural tartaric acid was synthesized and was applied to the asymmetric addition of diethylzinc to aldehyde and ketones. Moderate to good enantioselectivities were obtained in the asymmetric addition of diethylzinc to ketones with 10% mol catalyst loading at room temperature. Keywords: Tartaric acid, asymmetric addition, diethylzinc, aldehyde, ketone Introduction Chiral alcohols are ubiquitous in the structure of natural products and drug compounds, and are also important precursors for many other functional organic molecules. One of the most useful methods for the asymmetric preparation of sec-alcohols and tert-alcohols is the enantioselective addition of dialkylzinc reagents to carbonyl compounds with chiral ligands 1. Recent studies 2 showed the ligands with C2-symmetrical axes could catalyze dialkylzinc to aldehydes or ketones 3. Taking the advantage of the chirality of L-tartaric acid, we4 designed and synthesized a series of ligands with C2-symmetric axe, two of them were successfully applied to the asymmetric addition of diethylzinc to ketones. Recently, another new chiral ligands derived from L-tartaric acid were synthesized, as showed in Scheme 1. Furthermore, these ligands were employed as promoters in the addition of diethylzinc to aldehyde and ketones.
