Description of key information

In the key study (CRC Handbook, 2002) the melting point of Trimethylolpropan is cited to be 58 °C. This value lies in the temperature range of 57 - 59 °C as reported in several supporting studies (CRC Handbook, 2002; Römpp, 2009;

Werle et al., 2008; Verschueren, 1996; Kirk-Othmer, 1991).
