WebIn addition, melting points were obtained with the product mixed with meso-hydrobenzoin. The temperature range was 135.0-136.0℃ and 135.0-137.5℃. Although the recorded melting point values fall into the racemic range, but the results still indicate that the product is a meso-hydrobenzoin. WebMelting point of hydrobenzoin. For the case of (S,S) or (R,R) form, the melting point is 146-150 ℃ and the melting point of meso form is 137-139 ℃. 3 Melting point of racemic mixture is 120-125 ℃. 4 The measured melting point is 137.5 ℃, thus the product is expected to be meso compound.
