Methylthiourea Use and Manufacturing

Methods of Manufacturing

Under stirring, the methyl isothiocyanate was added dropwise to the concentrated ammonia water, after the addition, the excess ammonia was removed by heating. After the reaction mixture was decolorized by activated carbon, methyl thiourea crystals were precipitated by cooling. The yield is 74%-81%.

Uses

Used in organic synthesis.
