Properties and stability

Avoid contact with acids and oxides.

Storage method

1. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep container tightly sealed. should be kept away from oxidizer, do not store together.

2. Equip with corresponding varieties and quantities of fire-fighting equipment. The storage area should be equipped with emergency spill treatment equipment and suitable containment materials.

Synthesis method

1. Obtained from the reaction of methyl ethyl ketone and hydroxylamine hydrochloride. It can also be reacted with hydroxylamine sulfate. 2. It is prepared by reacting methyl ethyl ketone, ammonium hydronitride and sulfuric acid as raw materials. The reaction formula is as follows:

Purpose

1. Mainly used as anti-skinning agent and silicone curing agent for alkyd resin coatings. This product is used as an antioxidant to prevent skin formation and is more effective than butyraldehyde oxime and cyclohexanone oxime. 2.Used as deoxidizer in boiler water system. Used as anti-skinning agent and silicone curing agent for alkyd resin coatings.
