Similar observations were made by Emery and Wright, who state: “An accurate determination of the melting temperature in this way (the rate of heating was such as to give a rise in temperature of about 1° per minute) is rendered difficult by the fact that ‘aspirin’ decomposes on heating, as evidenced in the depression of the melting temperature of the pure substance of about 1° for every five minutes’ heating just below its melting temperature.”
