Umkhiqizi Amanani Amahle weTetraHyDroforuran CAS: 109-99-9

Umkhiqizi Intengo Elungile I-Tetrahydrofuran Cas: 109-99-9 Isithombe esifakiwe

Incazelo emfushane:

I-TetrahyDroforunan (thf) iwuketshezi olungenamibala, olushintshayo ngephunga eline-ethereal noma eline-acetonelible futhi elingabonakali ngamanzi futhi i-organic solvents.tetrahydrof.tetrahydrof. Isitoreji Eside Ngokuxhumana nomoya kanye nokungabikho kwe-antioxidant kungadala ukuthi i-thf ibolile ibe yi-peroxides eqhumayo.

Case: 109-99-9

Izicelo tetrahydrofon

I-Tetrahydroforan isetshenziswa ekwenziweni kwama-polymers kanye namakhemikhali ezolimo, amakhamisha kanye nama-Commodity. Imisebenzi yezokukhiqiza evame ukwenzeka ezinhlelweni ezivaliwe noma ngaphansi kwezilawuli zobunjiniyela ezikhawulela ukuvezwa kwabasebenzi nokukhululwa kwimvelo. I-THF nayo isetshenziswa njenge-solvent (isib Yize ngokwemvelo thf ekhona ephulweni lekhofi, avutha ama-chickpeas, futhi inkukhu ephekiwe, ukuvezwa kwemvelo akuhloselwe ukuba yingozi ebalulekile.
I-Butylene Oxide isetshenziswa njenge-fumigant futhi i-innadmixture nezinye izinhlanganisela. Kusetshenziswa amandla okuqinisa uphethiloli maqondana nokwakheka kombala we-andsludge.
I-Tetrahydroforunan isetshenziswa njengezinsika ze-solvent, ama-vinyls, nama-polymers aphezulu; njengendlela ephakathi nendawo ephakathi nendawo, kanye ne-metal hydride accetions; Futhi ku-synthesisuc i-succucinic acid ne-butrolactone.
I-solvent yama-polymers aphezulu, ikakhulukazi i-polyvinyl chloride. Njengendlela yokuphendula ephakathi kwe-grignard kanye ne-metal hydride ukusabela. Ekuhlolweni kweBurtiverolactone, i-SucCinic acid, i-1,4-butanediol diacetate. Solvent kumasu omlando. Ingahle isetshenziswe ngaphansi kokudla kwe-Federal, izidakamizwa & izimonyo zokwenziwa kwezindatshana zokufaka, ukuthutha, noma ukugcinwa kokudla uma inani le-residial alidluli ku-1.5% yefilimu: Fed. Layiza. 27, 3919 (APR. 25, 1962).
I-Tetrahydroforunan isetshenziswa ngokuyinhloko (80%) ukwenza i-polytetramethylene ether glycol, i-polymer eyisisekelo esetshenziswe ngokuyinhloko ekwenziweni kwemicu ye-elastomeric (isib. Izinsalela (20%) zisetshenziswa kwizicelo ze-solvent (isib. Amamitha amapayipi, ama-adhesing, ama-inks wokuphrinta, kanye ne-tape kazibuthe) futhi njenge-solvent yokusabela) kanye nokuguqulwa kwemithi.
