Decomposes on warming. This produces toxic fumes of tetramethylsuccinonitrile (see ICSC 1121) and cyanide. May decompose explosively on shock, friction or concussion. May explode on heating. Reacts violently with alcohols, oxidants, ketones such as acetone, aldehydes and hydrocarbons such as heptane. This generates fire and explosion hazard.

Use as an initiator for the polymerization or copolymerization of vinyl acetate and acrylate. Can
also be used as a blowing agent.
The tissue was embedded with methyl acrylate using a catalyst. An initiator for high molecular
polymers. Rubber, plastic, foaming agent. Polyvinyl chloride plastic activator.
Production methods Acetone, hydrazine hydrate and sodium cyanide are used as raw materials:
The above condensation reaction temperature was 55 to 60 ° C, the reaction time was 5 hours,
and then the temperature was cooled to 25 to 30 ° C for 2 hours. When the temperature is
lowered to 10 ° C or lower, chlorine is started, and the reaction is carried out at a temperature of
20 ° C or lower.
The material ratio is: HCN: acetone: = 1L: 1.5036 kg: 0.415 kg.
The reaction is carried out by using acetone cyanohydrin and hydrazine hydrate, followed by
oxidation with liquid chlorine or oxidation with sodium hypochlorite using aminobutyronitrile.
Category flammable solid
Toxicity classification
Acute Toxicity Oral - Rat LDL0: 670 mg / kg; Oral - Mouse LD50: 700 mg / kg
Explosive hazard characteristic explosive oxidant; easy to oxidize, unstable, decomposed by heat,
and explodes with heptane, acetone
Flammable hazard characteristics encounter open flame, high temperature, oxidant flammable;
decomposition of combustible gas by heating; combustion produces toxic nitrogen oxides
Storage and transport characteristics The warehouse is ventilated and low temperature dry; it is
stored separately from the oxidant.
Extinguishing agent water, dry sand, carbon dioxide, foam, 1211 fire extinguishing agent.
Fire Hazard
Excerpt from ERG Guide 150 [Substances (Self-Reactive / Temperature Controlled)]:
Self-decomposition, self-polymerization, or self-ignition may be triggered by heat, chemical
reaction, friction or impact. Self-accelerating decomposition may occur if the specific control
temperature is not maintained. These materials are particularly sensitive to temperature rises.
Above a given "Control Temperature" they decompose or polymerize violently and may catch fire.
May be ignited by heat, sparks or flames. Those substances designated with a (P) may polymerize
explosively when heated or involved in a fire. Some may decompose explosively when heated or
involved in a fire. May burn violently. Decomposition or polymerization may be self-accelerating
and produce large amounts of gases. Vapors or dust may form explosive mixtures with air. (ERG,
2016)
Chemical Dangers
Decomposes on warming. This produces toxic fumes of tetramethylsuccinonitrile (see ICSC 1121)
and cyanide. May decompose explosively on shock, friction or concussion. May explode on
heating. Reacts violently with alcohols, oxidants, ketones such as acetone, aldehydes and
hydrocarbons such as heptane. This generates fire and explosion hazard.
