Solid+liquid) phase diagrams were constructed for cyclohexanone+ o cresol
or m cresol
solid addition compounds form with the empirical formula: o CH 3C 6H 4OH·C 6H 10 O
m CH 3C 6H 4OH·C 6H 10 O
T mp of the compounds are 241 00 and 261 60 K
respectively.The eutectics are at x=0 397
T=232 54 K and x=0 794
T=210 26 K in x C 6H 10 O+(1- x)o CH 3C 6H 4OH. The eutectics are at x=0 244
T=244 75 K and x=0 927
T=219 19 K in x C 6H 10 O+(1- x)m CH 3C 6H 4OH.The solid phase transition temperature for C 6H 10 O is 220 24 K.Compound formation is attributed to hydrogen bonding between the carbonyl oxygen in cyclohexanone and hydroxyl hydrogens in phenol.
