FAQs

What is propionic anhydride?

Propionic anhydride is a colorless liquid with a pungent odor, molecular formula C6H10O3, also called propanoic anhydride, propanoic acid anhydride or methylacetic anhydride. It is a simple carboxylic acid anhydride, widely used as a reagent in organic synthesis, in the manufacture of cellulose derivatives, as a dehydrating agent in some sulfonations and nitrations, as an acylating agent, as a raw material for the manufacture of dyes, pharmaceutical products, agrochemicals, fragrances, etc. It is soluble in ethanol, methanol, chloroform, ethyl ether, isopropanol, etc. It decomposes in contact with water forming propionic acid.

What is propionic anhydride used for?

Propionic anhydride is used in organic synthesis as an esterifying agent in acylation reactions, e.g. for the manufacture of cellulose esters, perfumes, oils, synthetic resins, rubber accelerators, dyes, dye intermediates, pharmaceutical intermediates, agrochemicals, etc. It is also used as a dehydrating agent in some sulfonations and nitrations.

What are the applications of propionic anhydride?

Propionic anhydride is used in organic synthesis as an esterifying agent in acylation reactions, e.g. for the manufacture of cellulose esters, perfumes, oils, synthetic resins, rubber accelerators, dyes, dye intermediates, pharmaceutical intermediates, agrochemicals, etc. It is also used as a dehydrating agent in some sulfonations and nitrations.

What is the CAS number of propionic anhydride?

The CAS number of propionic anhydride is 123-62-6.

What is the difference between propionic anhydride and propanoic anhydride?

. None, they are two different ways of naming the same compound.

What is the difference between propionic anhydride and propionic acid anhydride?

. None, they are two different ways of naming the same compound.

What is the melting point of propionic anhydride?

The melting (freezing) point of propionic anhydride is -42 °C.

What is the boiling point of propionic anhydride?

The boiling point of propionic anhydride is 167 °C.

What is the solubility of propionic anhydride?

Propionic anhydride is soluble in most organic solvents such as ethanol, methanol, chloroform, ethyl ether, isopropanol, etc.; however, in contact with water it slowly hydrolyzes and decomposes to form propionic acid.

What is the density of propionic anhydride?

The density of propionic anhydride is 1.012 g/mL at 20 °C.

What are the safety precautions for propionic anhydride?

The indications according to the CLP (Classification, Labeling and Packaging) Regulation are: H314; P280, P303+P361+P353, P305+P351+P338, P310, P321, P405, P501. The symbol or pictogram according to GHS (Globally Harmonized System of Classification and Labelling of Chemicals) is: GHS05. Propionic anhydride is for professional use only.
