Methods to prepare lactic acid from acetaldehyde
A fairly simple two step synthesis involves nucleophilic addition of $\ce{HCN}$ to the carbonyl group and then aqueous hydrolysis of the nitrile to yield the carboxylic acid product.

Acetylene + $\ce{HCN-Ba(CN)2}$ → vinyl cyanide
Vinyl cyanide - hydrolysis → acetaldehyde cyanohydrin
Acetaldehyde cyanohydrin - dil HCl → lactic acid
