Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH 2) 4 O. The compound is classified as heterocyclic compound , specifically a cyclic ether . It is a colorless, water- miscible organic liquid with low viscosity .
2,2,5,5-tetramethyltetrahydrofuran (TMTHF) or 2,2,5,5-tetramethyloxolane (TMO) is a heterocyclic compound with the formula C 8 H 16 O, or (CH 3) 2 (C(CH 2) 2 OC)(CH 3) 2.It can be seen as derivative of tetrahydrofuran (oxolane) with four methyl groups replacing four hydrogen atoms on each of the carbon atoms in the ring that are adjacent to the oxygen.
The name "furan" comes from the Latin furfur, which means bran [5] (furfural is produced from bran). The first furan derivative to be described was 2-furoic acid , by Carl Wilhelm Scheele in 1780. Another important derivative, furfural , was reported by Johann Wolfgang Döbereiner in 1831 and characterised nine years later by John Stenhouse .
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
In terms of its structure, it consists of a tetrahydrofuran ring substituted in the 2-position with a hydroxymethyl group. It is a colorless liquid that is used as a specialty solvent and synthetic intermediate, e.g. to 3,4-dihydropyran. It is prepared by hydrogenation of furfural. [1] It is a precursor to 1,5-pentanediol. [2]
In chemistry, 3,3,4,4-tetramethyltetrahydrofuran-2,5-dione is a heterocyclic compound with the formula C 8 H 12 O 3, or (CH 3) 2 (COC 2 COO)(CH 3) 2.It is a white crystalline solid with a pungent camphoraceous odor.
2-Methyltetrahydrofuran (2-MeTHF) is an organic compound with the molecular formula C 5 H 10 O. It is a highly flammable, mobile liquid. It is mainly used as a replacement for Tetrahydrofuran (THF) in specialized applications for its better performance, such as to obtain higher reaction temperatures, or easier separations (as, unlike THF, it is not miscible with water).
