How do you make acetic anhydride?
Acetic anhydride can by prepared by the dehydration of acetic acid at 800°C. Alternatively, the reaction between the acid chloride and a salt of acetic acid (e.g. sodium acetate) yields acetic anhydride and a salt.
What is the melting point of acetic anhydride?
-73.1 °C
Is acetic anhydride a Lachrymator?
Besides being reactive, it is also characterized as a combustible compound. This simply means that, under specific conditions, acetic anhydride can become ignitable and create a fire hazard. This compound is a lachrymator, which means it hurts your eyes and makes them water. It is also toxic if ingested.
What are the uses of acetic anhydride?
The largest volume use for acetic anhydride is as a raw material for cellulose acetate fibers and plastics. It is widely used as an acetylating agent or in chemical synthesis. Acetic anhydride is also a key raw material for aspirin, acetaminophen and other pharmaceuticals manufacturing.
How do you dispose of acetic anhydride?
11). Contact a licensed professional waste disposal service to dispose of this material. Burn in a chemical incinerator equipped with an afterburner and scrubber but exert extra care in igniting as this material is highly flammable. Product or containers must not be disposed together with household garbage.
What is the mass of acetic anhydride?
102.09 g/mol
Why is acetic anhydride used instead of acetic acid?
Acetyl chloride and acetic anhydride are often used instead of acetic acid because they are more reactive and give better yields of product.
