Melting Point was determined using a Biichi B-545 Melting Point Apparatus. A glass. melting point capillary was filled to a height of about 1.5 cm with the test substance, packing it down with a stainless steel rod. The instrument was set for 20C/min heating rate in order to determine the approximate melting point (56C), as determined by the instrument's automatic melting point detection (based on optical transmission).
