2synthesis methods

Product Name:1-hydrazino-3-(methylthio)propan-2-ol
CAS Number:14359-97-8
Molecular formula:C4H12N2OS
Molecular Weight:136.22

Add 226.25g hydrazine hydrate to 1000ml reaction flask, heat to 90℃, and add 104.17g of glycidyl ether under stirring. The temperature of the reaction system was controlled at 90℃, and then the excess hydrazine hydrate was concentrated under reduced pressure to obtain 120.10g thick colorless liquid. The purity of the gas phase was 96.8%, namely 1-hydrazino-3-(methylthio)propan-2-ol, and the yield was 88.30%.

Reaction Conditions:

with hydrazine hydrate at 90; for 1 h;

Steps:

3 Example 3Preparation of 3-methylthio-2-hydroxy-propyl hydrazine:

In a 1000ml reaction flask,Hydrazine hydrate 226.25g,Heat to 90°C,104.17 g of glycidyl sulfide prepared in Example 1 was added dropwise with stirring.Control the acceleration,The temperature of the reaction system is controlled at 90 °C.After the addition of insulation 1.0h,Excess hydrazine hydrate was concentrated under reduced pressure to obtain 120.10 g of a viscous colorless liquid.The purity of the gas phase was 96.8%, ie, 3-methylthio-2-hydroxy-propyl hydrazine, and the yield was 88.30%.
