Abstract

The present study reports a differential scanning calorimetry (DSC) study of the amino acids sarcosine [CAS Registry No. 107-97-1], α-alanine (dl) [CAS Registry No. 302-72-7], β-alanine [CAS Registry No. 107-95-9], N -benzyl-α-alanine (dl) [CAS Registry No. 40297-69-6], and N -benzyl-β-alanine [CAS Registry No. 5426-62-0] in the temperature interval from T = 268 K to their respective melting/decomposition temperatures. Temperatures and heat capacities as a function of temperature of all solids and the enthalpies and entropies of fusion of two of the amino acids, sarcosine and N -benzyl-β-alanine, are reported.
