The invention relates to a process for producing 3,3,3-trifluoro-2-hydroxypropionic acid. This process includes the step of (a) bringing a 1,1-dihalogeno-3,3,3-trifluoroacetone into contact with a basic aqueous solution. The obtained 3,3,3-trifluoro-2-hydroxypropionic acid may be reacted with a C

lower alcohol under an acidic condition, thereby producing a 3,3,3-trifluoro-2-hydroxypropionate. This propionate may be reacted with a hydride reducing agent (e.g., sodium borohydride), thereby producing 3,3,3-trifluoro-2-hydroxypropanol. These products (i.e., 3,3,3-trifluoro-2-hydroxypropionic acid and its derivatives) are important intermediates for medicines and liquid crystals.
