Compounds of the formula
or
wherein
n is 0 or 1;
R, and R2 are independently H, -OH, alkyl,
X is
or
; and
R3 is H, -OH, -COO- (alkyl), alkyl, or alkoxy, provided that the inhibitor has at least three rings, are effective inhibitors of the polymerization of vinylic monomers, particularly acrylic monomers. The inhibitors are easily, efficiently, and thoroughly removed from the solution with the monomer by contact with charcoal.

OH, where n=22-24, are disclosed. The methods may include reacting a wax having a transformable functional group and a curable compound in the presence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than 85° C., and solidifying the acrylate. The methods may thereby provide safe and cost effective methods for curable wax production at large scale.
