Definitions
- the present invention relates to a method for producing 2-hydroxy-4-methylthiobutanoic acid, which is useful as a feed additive or the like.
- an object of the present invention is to provide an efficient and inexpensive method for producing 2-hydroxy-4-methylthiobutanoic acid without a large amount of waste.
- the above reaction may be carried out without a solvent, but is preferably carried out in the presence of a solvent in order to make the reaction proceed smoothly.
- the solvent is not particularly limited as long as it is inert to the reaction, and examples thereof include aromatic hydrocarbons such as benzene, toluene, xylene, and ethylbenzene; pentane, hexane, heptane, and the like. Aliphatic hydrocarbons such as octane; cycloaliphatic hydrocarbons such as cyclohexane and methylcyclohexane; acetone, methanol and the like can be used. Of these, reaction Solvents that easily dissolve the solvent, such as methanol and acetate, are particularly used.
- methanol produced as a by-product in the third step is converted to methyl formate by a dehydrogenation reaction or a force ruponylation reaction with carbon monoxide or the like, and is used as a raw material component in the second step. I do.
