Synthesis of 4-hydroxybenzyl alcohol

Preparation of 4-hydroxybenzyl alcohol

Alternative Names: 4-hydroxybenzyl alcohol; 4-(Hydroxymethyl)phenol; 623-05-2; P-Hydroxybenzyl alcohol; P-Methylolphenol; 4-Methylolphenol;

30 g of phenol are dissolved in 150 ml (a slight excess) of 10% sodium hydroxide; 35 g (excess) of 40% formaldehyde solution are added, and the whole allowed to remain at room temperature for 6 days. Then it is neutralized with hydrochloric acid, extracted repeatedly with ether, and the latter removed on a water bath. If necessary, the residue is steam distilled to remove unchange phenol, and the obtained mixture of ortho and para benzyl alcohols is shaken with cold benzene until nothing further dissolves. The ortho compound, which is much the more soluble, is thus separated from the para-isomer. Yield including both compods, 80% theoretical (32 g). o-Hydroxybenzyl alcohol (saligen) forms colorless crystals; m.p 82° C; the p-hydroxybenzyl alcohol (4-hydroxybenzyl alcohol) melts at 112° C.
