M. Barrio et al., PLASTIC MOLECULAR ALLOYS - THE BINARY-SYSTEM TRIS(HYDROXIMETHYL)AMINOMETHANE 2-AMINO-2-METHYL-1,3-PROPANEDIOL, Journal de chimie physique et de physico-chimie biologique, 91(2), 1994, pp. 189-202
The binary phase diagram of two plastic crystals, tris (hydroxymethyl)
aminomethane (TRIS) and 2-amino 2-methyl 1,3-propanediol (AMP) has be
en determined by means of thermal analysis and X-ray powder diffractio
n, between room temperature and 450 K (liquid state). In the plastic p
hase complete miscibility is observed, i.e. molecular alloys can be fo
rmed at any mole fraction. From this result it is concluded that the A
MP cubic phase has the same space group as TRIS (lm3m).
