What is Trifluoroacetic anhydride?
- Clear, colorless liquid
- Trifluoroacetic anhydride is a strong dehydrating agent with a wide range of chemical reactivity. It is used as a solvent, catalyst, dehydration condensing agent and retaining agent in the synthesis of a variety of polymers and fine chemicals. It is widely used in dyes, photosensitive materials, and liquid crystals. Display materials, aerospace science and technology, pesticides, medicine, polymer materials, etc., improve the speed of polymerization reaction and the yield of products, and be used as derivative chemical reagents in gas chromatography and high performance liquid chromatography to treat toxic metabolites in meat, fruits and vegetables. The detection of bacterin has very good development and application prospects.
- Trifluoroacetic anhydride is a colorless and transparent liquid, m.p.-63.5℃, b.p.39.15℃, relative density 1.4980, soluble in water, irritating and volatile.
- React with carboxylic acid
Trifluoroacetic anhydride can react with carboxylic acid to generate activated acid anhydride, which greatly improves the electrophilic properties of carboxylic acid. For example, the activated anhydride produced by the reaction of trifluoroacetic acid and benzoic acid undergoes Friedel-Crafts acylation with methoxybenzene, and the yield is as high as 98%. - In the presence of a weak base, trifluoroacetic anhydride can be used as a dehydrating agent to dehydrate amides, oximes, hydroxy ketones or hydroxy acid esters to produce corresponding nitriles and unsaturated ketones or carboxylic acid esters; Glycols and ortho-hydroxy acid derivatives are oxidized to ortho-diketones. Commonly used weak bases are triethylamine, pyridine, 2,6-lutidine and so on.
Trifluoroacetic anhydride Uses
- Trifluoroacetic anhydride used as analytical reagents, solvents, catalysts, dehydration condensing agent, protection agent of trifluoroacetylation of carboxyl and amino; used as Intermediate of fluorine fine chemicals, pharmaceutical, agrochemical.
- Trifluoroacetic anhydride is an intermediate of Tetranil.
- Trifluoroacetic anhydride is used as analytical reagents, solvents, catalysts, dehydration condensing agents and protective agents during trifluoroacetylation of hydroxyl and amino groups
- Trifluoroacetic anhydride is used as a pesticide intermediate.
- Trifluoroacetic anhydride is used in the esterification reaction in organic synthesis. It can also be used as a solvent, analytical reagent, catalyst and dehydration condensation agent.
- Trifluoroacetic anhydride is used as analytical reagent, solvent, catalyst, dehydrating condensation agent, protective agent for carboxyl and amino trifluoroacetylation; raw material for preparing organic fluorine fine chemicals, medicines, and pesticides.
- Trifluoroacetic anhydride is used as an analytical reagent, solvent, catalyst, dehydration condensation agent, and protective agent for trifluoroacetylation of hydroxyl and amino groups.
- Trifluoroacetic anhydride is used as analytical reagent, solvent, catalyst, nitration reaction accelerator, dehydration condensing agent, protective agent for hydroxyl and amino trifluoroacetylation, and organic synthesis. Analyze biologically active compounds in Chemicalbook by gas chromatography. Protective agent for primary and secondary amines. It is also used for the oxidation of aldehydes into acids, esters and amines. Derivative grades are used to protect primary and secondary amines. Derivatives are more volatile.
Application of Trifluoroacetic anhydride
CN202010981521.5 discloses a preparation method of thioglycolic anhydride, comprising the following steps: vaporization of trifluoroacetic anhydride: vaporizing trifluoroacetic anhydride in a vaporization device, and waiting for use; synthesis of thioglycolic anhydride: After preheating the internal temperature of the suspended gas-solid reaction device to 45-65 °C, the vaporized trifluoroacetic anhydride is passed into the suspended gas-solid reaction device, and the sulfite is intermittently added from the top of the suspended gas-solid reaction device. Diacetic acid, after 2 hours of reaction, stop feeding vaporized trifluoroacetic anhydride from the air inlet, stop heating, and export the obtained solid product from the discharge port;
Purification of thioglycolic anhydride: The solid product was washed with refrigerated anhydrous petroleum ether and anhydrous ether, respectively, to obtain pure thioglycolic anhydride. The thioglycolic anhydride synthesized by the invention has high purity and high yield, and the erdosteine prepared by reacting it with homocysteine thiolactone hydrochloride as a raw material has high yield.
CN201310281976.6 discloses a method for improving the water resistance of starch plastics. It belongs to the high value-added utilization of renewable biomass resources.
In this method, trifluoroacetic anhydride is added to starch as an internal plasticizer, and the starch and trifluoroacetic anhydride undergo an esterification reaction to generate an ester group. Further, it is extruded through a twin-screw extruder to obtain a starch plastic plasticized in trifluoroacetic anhydride. Trifluoroacetic anhydride contains fluorine atoms, and fluorine atoms have relatively low surface energy. Therefore, the use of acid anhydride groups in trifluoroacetic anhydride to graft fluorine atoms to the surface of starch molecules can improve the water resistance of starch plastics.
