Properties and stability

Avoid withStrong oxidants, acidsContact.

Storage method

Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. They should be stored separately from oxidants, acids, etc., and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

It is obtained by the addition of ethylene oxide and hydrazine hydrate. 40% of hydrazine hydrate and ethylene oxide in 65-75After the reaction, concentrate under reduced pressure to obtain 2-Hydroxyethylhydrazine. Some reaction examples control the temperature at 40 below, the yield is 60-64%.

Purpose

Used as organic synthesis intermediates, fuel oil stabilizers, and plant growth regulators. It is used as an intermediate raw material for the synthesis of furazolidone, and can also be used as a plant growth regulator, a stabilizer for polyurethane and polyacrylonitrile, and an oil well corrosion inhibitor.
