WINTER - 236-2B cs 2070/CS 2151 THERMAL ANALYSIS Date: July 29, 1981 Reference: Commercial Chemicals Analytical Request #16565 Introduction: - A light yellow liquid labeled CS-2151 and a light yellow solid labeled CS-2070 were received from V. Pothapragada 18 November 1980. The CS-2070 was reported to be the dried solid from CS-2151 which 1s 25% solids 1n water. The samples were submitted for PMN characterization. CS-2070 was subjected to thermal analysis and the melting point determined. Experimental : CS-2070 was submitted to Central Research analytical for TGA. The sample was heated 1n air at l0C/m1n. The request # was TA-2497. The melting point of CS-2070 was determined by CIPAC Method #MP2 employ ing a Thomas Hoover Uni-Melt apparatus. Results: A copy of the thermal analysis attached Indicates only 5% wt. loss by 280C and stable to 200C. The 50% weight loss occurs at about 370C. TGA Curve attached. The melting point range Indicates liquid first at 75C and complete melt. at. 145C- The sample appears waxy at room temprature. The sample was soft through the melting range and appeared like a gel. Benzoic acid melted at 122C. LDW/hc Attachment
