The highest THF value in the blood was at 1 hr post-application (about 200 mg/kg). For example, it can be used to dissolve polymers prior to determining their molecular mass using gel permeation chromatography. こちらのフォーム Reflecting its remarkable solvent properties, it penetrates the skin, causing rapid dehydration. Borane | BH3 | CID 167170 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Dermal LD50 Based on ATE data, the classification criteria are not met. About 200,000 tonnes of tetrahydrofuran are produced annually. those involving organometallic compounds. は各々異なります。 Tetrahydrofuran is one of the class of pentic cyclic ethers called oxolanes. In the presence of a solid acid catalyst, THF reacts with hydrogen sulfide to give tetrahydrothiophene.[27]. BH3 M.W:75.97. we can offer 10M solutin and 2.0M solution in THF Distillation of THF to dryness is avoided because the explosive peroxides concentrate in the residue. [14], The other main application of THF is as an industrial solvent for polyvinyl chloride (PVC) and in varnishes. XI. One danger posed by THF follows from its tendency to form the highly explosive peroxides tetrahydrofuran hydroperoxide on storage in air. It can be used to liquefy old PVC cement and is often used industrially to degrease metal parts. CAS RN: 14044-65-6 | Product Number: T2346 Borane - Tetrahydrofuran Complex (8.5% in Tetrahydrofuran, ca . However, the molecular species BH 3 is a very strong Lewis acid. 0.9mol/L) (stabilized with Sodium Borohydride) Purity: THF is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafloroacetylacetonato)copper(II). THF readily dissolves latex and is typically handled with nitrile or neoprene rubber gloves. [15] THF is water-miscible and can form solid clathrate hydrate structures with water at low temperatures.[16]. [21] The relative donor strength of THF toward a series of acids, versus other Lewis bases, can be illustrated by C-B plots. [10] A third major industrial route entails hydroformylation of allyl alcohol followed by hydrogenation to 1,4-butanediol. The method is similar to the production of diethyl ether from ethanol. THF can also be synthesized by catalytic hydrogenation of furan. It is a colorless, water-miscible organic liquid with low viscosity. THF is used as a solvent in 3D printing when using PLA plastics. Being polar and having a wide liquid range, THF is a versatile solvent よりお問い合わせください。, TCIの製品トピックスや新製品,製品パンフレット発行,展示会出展,キャンペーンなどをお知らせするメルマガです。ぜひ,ご登録ください。, ボラン - テトラヒドロフラン コンプレックス (8.5%テトラヒドロフラン溶液, 約0.9mol/L), テトラヒドロフランボラン (8.5%テトラヒドロフラン溶液, 約0.9mol/L). Vapor LC50 Based on ATE data, the classification criteria are not met. CAS RN: 14044-65-6 | 製品コード: T2346. The puckering of oxolanes", "2-Methyltetrahydrofuran, An alternative to Tetrahydrofuran and Dichloromethane",, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License, Monoxolane, the root of the group, synonymous with, This page was last edited on 5 September 2020, at 14:29. Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH 2) 4 O. THF is thus derivable from renewable resources. THF is used as a component in mobile phases for reversed-phase liquid chromatography. THF is often used in polymer science. THF is a weak Lewis base that forms molecular complexes with many transition metal halides. Trihydridoboron, also known as borane or borine, is an unstable and highly reactive molecule with the chemical formula BH 3.The preparation of borane carbonyl, BH 3 (CO), played an important role in exploring the chemistry of boranes, as it indicated the likely existence of the borane molecule.
