2-(Hydroxymethyl)octadecanoic acid → 2-Methylideneoctadecanoic acid

Participants

Reaction Steps

A 16.3 g sample of α-hydroxymethylstearic acid (0.0542 mole) and 6 drops of phosphoric acid (85%) are placed in a distillation flask and the mixture heated to 245°-255° C. in an oil bath under vacuum. The product, 2-hexadecyl acrylic acid, which distills over at 165°-175° C. at 0.1 mm (7.0 g) (43%), is recrystallized from acetone, m.p. 59°-63° C.
