摘要：
A process according to the present invention for producing a cyanohydrin compound flow-reacts a carbonyl compound with hydrogen cyanide in the presence of a catalyst, and can therefore reduce the residence time. This makes it possible to reduce the period of time over which the resulting cyanohydrin compound is exposed to an unreacted portion of the carbonyl compound. As a result, the resulting cyanohydrin compound can be prevented from reacting with the unreacted portion. This makes it possible to produce the cyanohydrin compound in good yield. That is, the process according to the present invention for producing a cyanohydrin compound produces a cyanohydrin compound in good yield from a carbonyl compound and hydrogen cyanide.
