Propionic anhydride is used as a esterifying reagent and as a reagent in organic synthesis. Notes. Store in cool place. Keep container tightly closed in a dry and
30 Jul 2019 I'm preparing to buy all the reagents necessary, and I had a question regarding the storage of propionic anhydride. The protocol calls for storing
it is an colorless acid anhydride that is widely used as a reagent in organic synthesis. Air & Water Reactions Decomposes exothermically in water to form a corrosive solution of propionic acid [Merck, 11th ed. 1989]. Synonyms : Propanoic anhydride Formula : C6H10O3 Molecular weight : 130,14 g/mol CAS-No.
It is soluble in alcohol, ether, chloroform, and alkalies, but decomposes in water. Propionic anhydride is a colorless liquid with a pungent odor, used chiefly as an acylating agent, e.g. as a raw material for dyes, pharmaceuticals, agrochemicals and fragrance chemicals. Propionic anhydride is also used for the production of cellulose acetate propionate. Propionic anhydride Compound with free spectra: 22 NMR, 9 FTIR, 1 Raman, 2 Near IR, and 7 MS. SpectraBase Compound ID: Iyj5Gr3jMSb: InChI: Due to the very short half-life (4 minutes) in aqueous media, propionic acid is a valid read-across substance for propionic anhydride, as it is the primary hydrolysis product. In vitro Gene Mutation.

Propanoic anhydride can also be obtained by dehydration of dry propionic acid using ethenone. Propionic anhydride was allowed to react with lauric acid in molten imidazole for 2 h at 100 °C. In the 1 H‐NMR spectrum, lauric acid can still be detected based on the signals at 2.34 and 1.66 ppm, which can be assigned to the methylene groups in α‐ and β‐position to the carbonyl group (Figure 8).

Propionic anhydride can be used as an acylating agent for the lipase-catalyzed esterification of alcohols. Recent studies indicate that the particle boards manufactured from wood chips modified with propionic anhydride show enhanced dimensional stability.

607-010-00-X Propionic Anhydride (DEA List I Chemical), also known as Propanoic anhydride, is a widely used reagent in organic synthesis. Ungraded products supplied by Spectrum are indicative of a grade suitable for general industrial use or research purposes and typically are not suitable for human consumption or therapeutic use. PROPIONIC ANHYDRIDE reacts exothermically with water. The reactions are sometimes slow, but can become violent when local heating accelerates their rate. Acids accelerate the reaction with water.
Propionic anhydride EC Number: 204-638-2 EC Name: Propionic anhydride CAS Number: 123-62-6 Molecular formula: C6H10O3 IUPAC Name: propanoyl propanoate . Type of Substance Due to the very short half-life (4 minutes) in aqueous media, propionic acid is a valid read-across substance for propionic anhydride, as it is the primary hydrolysis product. In a primary dermal irritation study, 2-4 Vienna White rabbits were dermally exposed to 1 ml of undiluted propionic acid (> 99 % pure), applied under occlusion to the shaved skin (2.5 x 2.5 cm) for 1, 5 and 15 min. No definitive skin sensitization studies have been conducted for propionic acid.
