Abstract
A process according to the present invention for producing a cyanohydrin compound is a process for producing a cyanohydrin compound by performing a reaction between a carbonyl compound such as an aldehyde compound and hydrogen cyanide in the presence of a catalyst, a content of the carbonyl compound in a reaction system being not more than 50 mol % with respect to the cyanohydrin compound. Thus provided is a process for producing a cyanohydrin compound in good yield from an aldehyde compound and hydrogen cyanide.
Claims7
A process for producing a cyanohydrin compound by performing a reaction between a carbonyl compound and hydrogen cyanide in the presence of a catalyst through a batch process,
- the process comprising the step of controlling a content of the carbonyl compound in a reaction system to not more than 50 mol % with respect to the cyanohydrin compound,
- the reaction between the hydrogen cyanide and the carbonyl compound being performed by either simultaneously or separately supplying the hydrogen cyanide and the carbonyl compound into a reactor vessel.
