The present invention relates to a method for preparing 3-methylthiopropionaldehyde by reacting methyl mercaptan with acrolein, in which deviations in the stoichiometry of methyl mercaptan to acrolein in the reaction to give 3-methylthiopropionaldehyde are compensated for by supplying or by forming 1,3-bis(methylthio)-1-propanol, and also to the use of 1,3-bis(methylthio)-1-propanol as a storage form of methyl mercaptan and/or 3-methylthiopropionaldehyde.

Method for preparing 3-methylthiopropionaldehyde

A compound, which is 1-(1,3-bis(methylthio)propoxy)-3-(methylthio)propan-1-ol, a composition containing the compound, a method for the preparation thereof, a method for preparing 3-methylthiopropionaldehyde by reacting 1-(1,3-bis(methylthio)propoxy)-3-(methylthio)propan-1-ol with acrolein, and also to the use of 1-(1,3-bis(methylthio)propoxy)-3-(methylthio)propan-1-ol or compositions containing the compound for the storage and/or transport of 3-methylthiopropionaldehyde and/or methyl mercaptan.
