Abstract
An object is to provide a method of producing a carboxylic acid fluoride at an increased product yield in a reaction system without forming HCl as a by-product, in other words, without forming a complex between HCl and a carboxylic acid fluoride as a product. The method comprising reacting a carboxylic acid chloride with a metal fluoride. In this production method, the carboxylic acid is a carboxylic acid having a carbon number of 1 to 7, the carboxylic acid is a carboxylic acid substituted with fluorine, or the carboxylic acid is trifluoroacetic acid.
Claims10
A method of producing a carboxylic acid fluoride, comprising reacting a carboxylic acid chloride with a metal fluoride,
- wherein the carboxylic acid chloride is allowed to flow as a gas through pellets and/or powders comprising the metal fluoride filled in a reactor to conduct the reacting,
- wherein the carboxylic acid chloride is derived from a carboxylic acid selected from the group consisting of formic acid, acetic acid, propanoic acid, n-butanoic acid, isobutanoic acid, n-pentanoic acid, isopentanoic acid, neopentanoic acid, n-hexanoic acid, isohexanoic acid, neohexanoic acid, n-heptanoic acid, isoheptanoic acid, neoheptanoic acid, and combinations thereof,
- wherein at least one hydrogen atom on the carboxylic acid may be replaced by fluorine, and
- wherein the metal fluoride is selected from the group consisting of at least one lithium fluoride, sodium fluoride, cesium fluoride, potassium fluoride, magnesium fluoride, calcium fluoride, barium fluoride, chromium fluoride, molybdenum fluoride, manganese fluoride, iron fluoride, cobalt fluoride, copper fluoride, nickel fluoride, zinc fluoride, silver fluoride, or combinations thereof.
