Stearic Acid
The aniline point of kerosene is 60-69 oC.
A degree is about 69 nautical miles, so 690.
Of course, unless you feel hot which probably means you should wear something cooler.
The Earth is not a perfect sphere, and the WGS84 system that we use for degree confluences includes a mathematical model (GRS80) of the Earth as an ellipsoid. Using established GRS80 constants, and the Vincenty Algorithm (PDF document), the distance between degrees of latitude (lines that run east-west) varies from 110.57km (68.71mi) at the equator (0 degrees latitude) to 111.69km (69.40mi) between 89 degrees latitude and the poles. For the purposes of the project, we don't take these variations in the distance between degrees of latitude into account when categorizing degree confluences. Using the same calculation methods, the distance between degrees of longitude (lines that run north-south) varies between 111.32km (69.17mi) at the equator (0 degrees latitude) to 1.95km (1.21mi) at 89 degrees latitude, one degree from the north or south pole. Because the lines of longitude meet at the poles, the distance between degrees of longitude at the poles is zero.
A degree of Latitude is 69 miles or 110kms
The melting point of pure stearic acid is around 69-72°C.
Biphenyl (C6H5)2 has a melting point of 69.2 degrees Celsius
Glacial (pure) stearic acid has a melting/freezing point of 69.6 degrees Celsius or 157 degrees Fahrenheit at 100 kPa. An experiment today showed that stearic acid becomes a solid at 51 degrees Celsius. It stops becoming a fully liquid at 54 degrees Celsius; it becomes a mix of sold and liquid.
Yes, stearic acid has a high melting point of around 69-71 degrees Celsius. It is a saturated fatty acid that forms a solid white waxy substance at room temperature.

Well, friend, diphenylmethane is a liquid at room temperature. It has a melting point of around -25 degrees Celsius, so it stays in its liquid form when the room is nice and cozy. Just like how we let our creativity flow freely, diphenylmethane does the same by staying in its liquid state at room temperature.
The melting point of a mixture of 50% 2-naphthol and 50% benzoic acid will depend on the exact proportion of each compound present and any potential interactions between them. However, the melting points of the individual compounds are approximately 122°C for 2-naphthol and 122-123°C for benzoic acid.
