용도

테트라 하이드로 푸란 (THF)은 또한 접착제, 비닐 필름 및 셀로판, 산업용 수지, 엘라스토머, 코팅 및 인쇄 잉크와 같은 분야에서 다양한 용도로 사용되는 다용도 솔벤트입니다. THF의 구체적인 용도는 PVC 시멘트의 배합입니다. THF 용제 시멘트는 경화 시간을 조절하기 위해 추가 용제 및 무기 충전제로 제형화할 수 있습니다. THF는 조인트 형성 전에 PVC 형 클리너로도 기능 할 수 있습니다. 테트라 하이드로 푸란 (THF)은 세정제, 페인트 제거제 및 스트립 핑 유체, 기능성 유체, 래커 및 코팅제, 접착제 및 기능성 유체 및 부식 방지제의 구성 요소로서 소비자 제품에 사용됩니다. 또한 이러한 목적을 위해 전문적으로 사용됩니다.

독성

테트라하이드로 퓨란이 피부에 직접 노출되었을 경우 염증을 일으킬 수 있다. 고농도로 노출되었을 경우에는 현기증이나 매스꺼움, 그리고 신경의 손상을 일으킬 수 있다. 그 외에도 백혈구가 감소하는 등 면역계쪽 질환도 보고가 된 경우도 있다. 그렇기 때문에 피부에 직접 닿지 않도록 주의하고, 증기를 흡입하는 경우가 적도록 이따금씩 환기를 시켜주는 것이 좋다.

화학적 성질

Tetrahydrofuran (THF) is an industrial solvent widely recognized for its unique combination of useful properties. DuPont THF is better than 99.9% pure with a small (0.025-0.040 wt % ) amount of butylated hydroxytoluene (BHT, 4-methyl-2,6-di-tertbutyl phenol) added as an antioxidant. Tetrahydrofuran is a cycloaliphatic ether and is not "photochemically reactive" as defined in Section k of Los Angeles County's Rule 66 (equivalent to Rule 442 of the Southern California Air Pollution Control District). THF has an ethereal odor. The Odor Threshold is listed @ 3.8 (3M), 20-50ppm, and 31ppm. It is also a common laboratory reagent and an intermediate in chemical syntheses of consumer and industrial products such as nutritionals, pharmaceuticals, and insecticides (HSDB, 2011).

용도

Tetrahydrofuran is used primarily (80%) to make polytetramethylene ether glycol, the base polymer used primarily in the manufacture of elastomeric fibers (e.g., spandex) as well as polyurethane and polyester elastomers (e.g., artificial leather, skateboard wheels). The remainder (20%) is used in solvent applications (e.g., pipe cements, adhesives, printing inks, and magnetic tape) and as a reaction solvent in chemical and pharmaceutical syntheses.

반응 프로필

Tetrahydrofuran reacts violently with oxidizing agents leading to fires and explosions [Handling Chemicals Safely 1980. p. 891]. Subject to peroxidation in the air. Peroxides or their products react exothermically with lithium aluminum hydride [MCA Guide for Safety 1973]. Thus, use as a solvent for lithium aluminum hydride has led to fires. Using potassium hydroxide or sodium hydroxide to dry impure Tetrahydrofuran that contains peroxides has resulted in explosions. A violent explosion occurred during the preparation of sodium aluminum hydride from sodium and aluminum in a medium of Tetrahydrofuran [Chem. Eng. News 39(40):57. 1961]. THF forms explosive products with 2-aminophenol [Lewis 3227].

인화성 및 폭발성

THF is extremely flammable (NFPA rating = 3), and its vapor can travel a considerable distance to an ignition source and "flash back." A 5% solution of THF in water is flammable. THF vapor forms explosive mixtures with air at concentrations of 2 to 12% (by volume). Carbon dioxide or dry chemical extinguishers should be used for THF fires.
THF can form shock- and heat-sensitive peroxides, which may explode on concentration by distillation or evaporation. Always test samples of THF for the presence of peroxides before distilling or allowing to evaporate. THF should never be distilled to dryness.

잠재적 노출

The primary use of tetrahydrofuran is as a solvent to dissolve synthetic resins, particularly polyvinyl chloride and vinylidene chloride copolymers. It is also used to cast polyvinyl chloride films, to coat substrates with vinyl and vinylidene chloride; and to solubilize adhesives based on or containing polyvinyl chloride resins. A second large market for THF is as an electrolytic solvent in the Grignard reaction-based production of tetramethyl lead. THF is used as an intermediate in the production of polytetramethylene glycol.

Carcinogenicity

THF showed little evidence of mutagenic activity in a variety of in vitro and in vivo assays.

저장

THF should be used only in areas free of ignition sources, and quantities greater than 1 liter should be stored in tightly sealed metal containers in areas separate from oxidizers. Containers of THF should be dated when opened and tested periodically for the presence of peroxides.

비 호환성

Forms thermally explosive peroxides in air on standing (in absence of inhibitors). Peroxides can be detonated by heating, friction, or impact. Reacts violently with strong oxidizers, strong bases and some metal halides. Attacks some forms of plastics, rubber and coatings.

폐기물 처리

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Concentrated waste containing peroxides-perforation of a container of the waste from a safe distance followed by open burning.
