Definition of truxillic acid
1
: any of several crystalline stereoisomeric cyclic dicarboxylic acids (C6H5)2C4H4(COOH)2 that yield cinnamic acid on distillation; 2,4-diphenyl-cyclobutane-1,3-dicarboxylic acid: such as
a
: an acid obtained from alpha-truxilline by hydrolysis or from cinnamic acid by irradiation — called also
alpha-truxillic acid
b
: an acid obtained from alpha-truxillic acid by heating with acetic anhydride and sodium acetate and convertible again into the alpha isomer by stronger heating — called also
gamma-truxillic acid
c
: an acid obtained from the potassium salt of alpha-truxillic acid by fusion with potassium hydroxide — called also
epsilon-truxillic acid
2
: truxinic acid
