Uses and synthesis of Tetrahydrofuran Liquid

Tetrahydrofuran Liquid, abbreviated as THF, is a heterocyclic organic compound that belongs to the group of ethers. It belongs to the class of ethers, and is the complete hydrogenation product of the aromatic compound furan.Tetrahydrofuran CAS 109-99-9 is one of the most powerful polar ethers, and is used as a moderately polar solvent in chemical reactions and extraction.
It is a colorless and volatile liquid at room temperature, and has an odor similar to that of ether.Tetrahydrofuran Raw Materials Soluble in Tetrahydrofuran Raw Materials is soluble in water, ethanol, ether, acetone, benzene and other organic solvents, known as "universal solvent".

Room temperature and water can be partially miscible, some of the unscrupulous reagent traders is to take advantage of this Tetrahydrofuran CAS 109-99-9 reagent to water profiteering. As THF has the tendency to form peroxide in storage, industrial products are usually added with antioxidant BHT. moisture content ≦ 0.2%. Low toxicity, low boiling point, good fluidity.

Applications / Functions of Tetrahydrofuran Liquid

Tetrahydrofuran Raw Materials, also known as monooxypentacyclic, oxetane, tetramethylene oxygen, is the intermediate of synthesizing pesticide phenylbutyl tin, in addition, it can be used directly in the production of synthetic fibers, synthetic resins, synthetic rubbers, and it is also the solvent of many polymerization materials, precision tapes, and electroplating industry, Tetrahydrofuran Liquid is also used in the production of hexanedinitrile, adipic acid and other chemicals. Tetrahydrofuran Liquid is also used in the production of hexanedinitrile, adipic acid, adipamide, butanedioic acid, butanediol, γ-butyrolactone, etc. In the pharmaceutical industry, it can be used in the production of cough, progesterone, Rifamycin and used as a pharmaceutical solvent.

Physicochemical Property of Tetrahydrofuran Liquid

Colorless transparent liquid with ether odor. Tetrahydrofuran Liquid is miscible with water, alcohols, ketones, benzene, esters, ethers and hydrocarbons.

Production methodprocess of Tetrahydrofuran Liquid

Tetrahydrofuran CAS 109-99-9 has the following five production processes.

(1)Furfural method

(2) Catalytic hydrogenation of maleic anhydride

(3) 1,4-butanediol dehydration cyclization method

(4) Dichlorobutene method

(5) Butadiene oxidation method

Industrial production was firstly used saccharaldehyde as raw material, and the mixture of saccharaldehyde and steam was passed into the reactor filled with zinc-chromium-manganese metal oxide (or palladium) catalyst, and the carbonyl group was taken off to form furan at 400-420 ℃; and then, using skeleton nickel as catalyst, the furan was hydrogenated at 80-120 ℃ to produce Tetrahydrofuran Raw Materials.

This method produces 1 ton of tetrahydrofuran and consumes about 3 tons of polysaccharide aldehyde. There are many production methods developed later, and the industrialized methods include the 1,4-butanediol catalytic dehydration cyclization method, which is called the Reppe method because butanediol is produced from acetylene and formaldehyde; and the production of Tetrahydrofuran Raw Materials by using 1,4-dichlorobutene, a by-product of the neoprene monomer chloroprene, which is called the dichlorobutene method; In recent years, catalytic hydrogenation of maleic anhydride has been developed.
