You can buy tetrahydrofuran (commonly known as THF) from Our online chemical store in 2.5L and 25L containers. This product is sold with over 99% purity and less than 0.05% water.

What is the difference between furan and tetrahydrofuran?

What about the « -furan » part of the THF name?which tells us that it is a derivative, or cousin, its parent molecule furan. THF differs only in that the double bond has been removed and replaced by four hydrogen atoms.

How to get rid of THF?

Tetrahydrofuran is a waste chemical stream component that can be disposed of in the following ways Controlled Incineration. In controlled waste containing peroxides, perforate the waste container from a safe distance and perform open burning.

Is tetrahydrofuran safe?

* Tetrahydrofuran can cause headache, nausea and dizziness. Very high exposures can cause unconsciousness and death. * Tetrahydrofuran may damage the liver and kidneys. *Tetrahydrofuran is a flammable liquid and dangerous fire hazard.

Is tetrahydrofuran toxic?

acute toxicity Low to moderate THF for all routes. Direct contact may cause irreversible corrosive damage to the eyes. However, THF is neither a skin irritant nor a sensitizer. In vitro and in vivo studies have shown that THF is not mutagenic.

Will tetrahydrofuran react with sodium?

as expected, Sodium metal is able to react with disulfides in THF Because the sodium ions formed due to the conversion of disulfides to thiolate anions can be better stabilized by coordination with THF molecules.

Who discovered tetrahydrofuran?

In 1956, WW Gilbert and BW Howk of DuPont Obtained a patent for the catalytic hydrogenation of maleic anhydride to produce THF. DuPont later applied for a patent on a process for hydrogenating furan to THF. Today, the predominant THF manufacturing process is the acid-catalyzed dehydration of 1,4-butanediol.

Is tetrahydrofuran volatile?

It is part of a group of glycol ethers low volatility and strong coupling properties. It is miscible with water and has surface tension properties, so it can be used in household and industrial cleaners.

What does tetrahydrofuran taste like?

Among other common laboratory solvents, THF has rather pungent ethereal smell – It’s not something you’re lining up for anyway, the ether itself will fill your nose in a blazingly fast and thorough fashion. Somehow, there was rarely a faint ethereal smell in the air—either nothing or a suffocating layer.

Why is THF used in Grignard?

Diethyl ether or THF is essential for the formation of Grignard reagents. The lone pair of electrons from the two ether molecules forms a complex with magnesium in the Grignard reagent (as shown in the figure below).this complex Helps stabilize organometallics and improve their reactivity.
