Pmn P-12-0284) United States Premanufacture Notification Environmental Protection Agency Number: P-12-0282-0284 Office of Chemical Safety and Pollution Prevention TSCA NEW CHEMICALS REVIEW PROGRAM STANDARD REVIEW RISK ASSESSMENT ON MEDIUM-CHAIN CHLORINATED PARAFFINS (PMN P-12-0282, P-12-0283) AND LONG-CHAIN CHLORINATED PARAFFINS (PMN P-12-0284) This assessment was conducted under EPA’s TSCA Section 5 New Chemicals Program. EPA is assessing Medium-chain Chlorinated Paraffin (MCCP) and Long-Chain Chlorinated Paraffin (LCCP) chemicals as part of its New Chemicals Review program. As with all Premanufacture Notice (PMN) submissions, EPA followed the approaches, methods and statutory provisions of TSCA section 5 for the chlorinated paraffin PMNs assessments. 1 CONCLUSIONS Based on its assessment of the available hazard and exposure information on P-12-0282, P-12- 0283, and P-12-0284, EPA/OPPT concludes the following pertaining to the manufacturing, processing and use1 of these PMN substances: 1. Occupational Exposures: given the assumptions, data and scenarios evaluated in this assessment, there were low risks found for workers from either dermal or inhalation exposures. 2. General Population Exposures (from environmental releases): given the assumptions, data and scenarios evaluated in this assessment, there were low risks found to humans from environmental releases via exposure to drinking water or fish ingestion. 3. Environmental Assessment: a. Using estimated environmental concentrations, the PMN substances may present an unreasonable risk following acute and chronic exposures to aquatic organisms. i. The two exceptions are the low-end estimates for aquatic concentrations for water releases from plastic converting use and commercial use of solvents, paints and adhesives (for the MCCP PMN P-12-0283) b. Using available measured concentrations of MCCP and LCCP congener groups in the environment as supporting information, the PMN substances: i. Are expected to partition to sediment and may partition to soil through land application of biosolids, and ii. May be released to the environment at levels at or above estimated concentrations of MCCP and LCCP congener groups that may present an unreasonable risk following acute and chronic exposures to aquatic organisms. 4. PBT Assessment: The PMN substances may be very persistent and very bioaccumulative. 1 The two MCCP PMNs (P-12-0282 and 0283) have six different uses, but the three major uses are: as an additive to plastics as a flame retardant and as a secondary plasticizer [43% of total production volume] and as an additive to rubber as a flame retardant and plasticizer [24%], and as an extreme pressure additive to lubricants [30%]. The LCCP PMN (P-12-0284) is used exclusively as an extreme pressure additive to metalworking fluids. 2 TABLE OF CONTENTS TABLE OF CONTENTS

Preparation of graphite oxide (GO) Graphite oxide was prepared from natural graphite (Jinglong Co., Beijing, China) according to 1 a modified Hummers method : 120 mL 98 wt% H2SO4 was poured into a beaker containing a mixture of 5 g natural graphite and 2.5 g NaNO3, and then the mixture was stirred in an ice bath for 30 min. 15 g KMnO4 was added slowly into the mixture, which was allowed to react for 2 h at a temperature no more than 20°C. Then, the temperature was risen to 35°C, and the reaction was performed for another 2 h. After that, the reactant mixture was poured slowly into 360 mL distilled water under violent stirring condition so as to control the temperature no more than 90°C, followed by further reaction at 75°C for 1 h.

    BATCH: je1a04 USER: jeh69 DIV: @xyv04/data1/CLS_pj/GRP_je/JOB_i01/DIV_je0301747 DATE: October 17, 2003 1 Vapor Pressures and Vaporization Enthalpies of the n-Alkanes from 2 C21 to C30 at T ) 298.15 K by Correlation Gas Chromatography 3 James S. Chickos* and William Hanshaw 4 Department of Chemistry and Biochemistry, University of MissourisSt. Louis, St. Louis, Missouri 63121 5 6 The temperature dependence of gas chromatographic retention times for n-heptadecane to n-triacontane 7 is reported. These data are used to evaluate the vaporization enthalpies of these compounds at T ) 298.15 8 K, and a protocol is described that provides vapor pressures of these n-alkanes from T ) 298.15 to 575 9 K. The vapor pressure and vaporization enthalpy results obtained are compared with existing literature 10 data where possible and found to be internally consistent. Sublimation enthalpies for n-C17 to n-C30 are 11 calculated by combining vaporization enthalpies with fusion enthalpies and are compared when possible 12 to direct measurements. 13 14 Introduction 15 The n-alkanes serve as excellent standards for the 16 measurement of vaporization enthalpies of hydrocarbons.1,2 17 Recently, the vaporization enthalpies of the n-alkanes 18 reported in the literature were examined and experimental 19 values were selected on the basis of how well their 20 vaporization enthalpies correlated with their enthalpies of 21 transfer from solution to the gas phase as measured by gas 22 chromatography.3 A plot of the vaporization enthalpies of 23 the n-alkanes as a function of the number of carbon atoms 24 is given in Figure 1.
