    ALPHABETICAL INDEX OF SUBSTANCES AND ARTICLES - 355 - NOTES TO THE INDEX 1. This index is an alphabetical list of the substances and articles which are listed in numerical order in the Dangerous Goods List in Chapter 3.2. 2. For the purpose of determining the alphabetical order the following information has been ignored even when it forms part of the proper shipping name: numbers; Greek letters; the abbreviations “sec” and “tert”; and the letters “N” (nitrogen), “n” (normal), “o” (ortho) “m” (meta), “p” (para) and “N.O.S.” (not otherwise specified). 3. The name of a substance or article in block capital letters indicates a proper shipping name. 4. The name of a substance or article in block capital letters followed by the word “see” indicates an alternative proper shipping name or part of a proper shipping name (except for PCBs). 5. An entry in lower case letters followed by the word “see” indicates that the entry is not a proper shipping name; it is a synonym. 6. Where an entry is partly in block capital letters and partly in lower case letters, the latter part is considered not to be part of the proper shipping name. 7. A proper shipping name may be used in the singular or plural, as appropriate, for the purposes of documentation and package marking. - 356 - INDEX Name and description Class UN No. Name and description Class UN No. Accumulators, electric, see 4.3 3292 Acid mixture, nitrating acid, see 8 1796 8 2794 8 2795 Acid mixture, spent, nitrating acid, see 8 1826 8 2800 8 3028 Acraldehyde, inhibited, see 6.1 1092 ACETAL 3 1088

August 2009 Table 4 is an alphabetical listing of the chemicals in the PAC data set. It provides Chemical Abstract Service Registry Numbers (CASRNs)1, PAC values, and technical information on the source of the PAC values. Table 4 presents all values for TEEL-0, PAC-1, PAC-2, and PAC-3 in mg/m3. The conversion of ppm to mg/m3 is calculated assuming 25 ºC and 760 mm Hg. The columns presented in Table 4 provide the following information: Heading Definition No. The ordered numbering of the chemicals as they appear in this alphabetical listing. Chemical Name The chemical name given to the PAC Development Team. CASRN The Chemical Abstract Service Registry Number for this chemical. TEEL-0 This is the threshold concentration below which most people will experience no adverse health effects. This PAC is always based on TEEL-0 because AEGL-0 or ERPG-0 values do not exist. PAC-1 Based on the applicable AEGL-1, ERPG-1, or TEEL-1 value. PAC-2 Based on the applicable AEGL-2, ERPG-2, or TEEL-2 value. PAC-3 Based on the applicable AEGL-3, ERPG-3, or TEEL-3 value. Source of PACs: Technical comments provided by the PAC development team that TEEL-0, PAC-1, indicate the source of the data used to derive PAC values. Future efforts PAC-2, PAC-3 are directed at reviewing, revising, and enhancing this information.

Box 3503, 11120 Belgrade, Serbia and Montenegro (e-mail: [email protected]) (Received 14 May, revised 26 July 2004) Abstract: Rate constants for the reaction of diazodiphenylmethane with isomeric pyridine carboxylic acids were determined in chosen protic and aprotic solvents at 30 °C, using the well known UV spectrophotometric method. The values of the rate constants of the investigated acids in protic solvents were higher than those in aprotic solvents. The second order rate constants were correlated with solvent pa- rameters using the Kamlet-Taft solvatochromic equation in the form: log k =logk0 + sp*+aa + bb. The correlation of the obtained kinetic data were performed by means of multiple linear regression analysis taking appropriate solvent parameters. The signs of the equation coefficients were in agreement with the postulated reaction mechanism. The mode of the influence of the solvent on the reaction rate in all the investigated acids are discussed on the basis of the correlation results. Keywords: pyridine carboxylic acids, diazodiphenylmethane, rate constants, solvent parameters, protic and aprotic solvents. INTRODUCTION The relationship between the structure of carboxylic acids and their reactivity with diazodiphenylmethane (DDM) has been studied by many authors,1,2 with particular regard to the influence of the solvent.

PS synthesis was carried out by a phosphite-triester approach, using 2-cyanoethyI- N,N,N' ,N' -tetraisopropylphosphorodiamidite (phosphoramiditate) as the phosphorylating agent, for the formation of phosphate linkage between serine and diacylglycerol. 1,2- Diacylglycerol, obtained from PC hydrolysis by phospholipase C, was coupled with N-t-BOC- L-serine benzhydryl ester phosphoramidite with tetrazole as catalyst.
