3

sec-AMYL ACETATE
626-38-0

The vapour is heavier than air

The substance decomposes upon burning, producing toxic gases and vapours • Reacts violently with strong acids, strong oxidants, strong alkalis • Attacks many plastics

3

BUTYL ACETATE
123-86-4

3

tert-BUTYL ACETATE
540-88-5

3

CYCLOHEXYL ACETATE
622-45-7

Reacts with oxidants • Reacts on contact with water or humidity to release acetic acid causing in metallic containers a slow corrosion hazard

3

ETHYL ACETATE
141-78-6

The vapour is heavier than air and may travel along the ground; distant ignition possible

Heating may cause violent combustion or explosion • The substance decomposes under influence of UV light, bases, acids • Upon heating, toxic fumes are formed • The solution in water is a weak acid • Reacts with strong oxidants, bases or acids • Attacks many metals in presence of water • Attacks plastics

3

The vapour mixes well with air, explosive mixtures are easily formed

Reacts violently with strong oxidizers, causing fire and explosion hazard

ISOBUTYL ACETATE
110-19-0

Reacts with strong oxidants, nitrates, strong alkalis and strong acids, causing fire and explosion hazard

3

ISOPROPYL ACETATE
108-21-4

The vapour is heavier than air and may travel along the ground; distant ignition possible

The substance decomposes slowly on contact with steel when exposed to air producing acetic acid and ispropyl alcohol • Reacts violently with oxidizing materials • Attacks many plastics

3

1-METHOXY-2-PROPYLACETATE
108-65-6

Reacts with strong oxidants

110-49-6

The vapour is heavier than air

Reacts with strong oxidants causing fire and explosion hazard

3

METHYL ACETATE
79-20-9

The vapour is heavier than air and may travel along the ground; distant ignition possible, and may accumulate in low ceiling spaces causing deficiency of oxygen

The substance decomposes on heating under influence of air, bases, strong oxidants, water, UV-light, causing fire and explosion hazard • The substance is a strong reducing agent and reacts with oxidants • Attacks many metals in presence of water • Attacks plastics

3

PHENYL ACETATE
122-79-2

Reacts with oxidants

POTASSIUM ACETATE
127-08-2

Dust explosion possible if in powder or granular form, mixed with air

On combustion, forms potassium and carbon oxides • The substance decomposes on heating, on contact with strong acids produces acetic acid fumes • The solution in water is a medium strong base

PROPYL ACETATE
109-60-4

The gas mixes well with air, explosive mixtures are easily formed

The substance decomposes on burning producing irritating or poisonous gases • Can react vigorously with oxidizing materials • Attacks plastics

3

SODIUM ACETATE
127-09-3

Dust explosion possible if in powder or granular form, mixed with air

The substance decomposes on heating above 120°C or on contact with strong acids producing acetic acid • The solution in water is a medium strong base
