DESCRIPTION
I-Tetrahydrofuran (THF)
I-Tetrahydrofuran (THF) iyincibilikisi yemvelo engenambala, eguquguquka kakhulu enefomula yamangqamuzana C₄H₈O . Isetshenziswa kakhulu ekuhlanganiseni kwe-polymer, kwezemithi, ekuhlanganiseni, ekunamathiseleni, nasekucwaningeni kwamakhemikhali ngenxa ye-solvency yayo enhle kakhulu, i-viscosity ephansi, kanye nekhono lokuncibilikisa inhlanganisela ebanzi ye-polar ne-non-polar.
I-THF ibaluleke kakhulu njenge-solvent ekukhiqizeni i-polyurethane, ukucubungula kwe-PVC, kanye nokusabela kwe-Grignard , futhi iyahambisana nezinqubo eziningi zamakhemikhali zezimboni nezaselabhorethri.

Amanani abonisiwe ajwayelekile ku-THF yezinga lezimboni kanye nelabhorethri.
I-Tetrahydrofuran ikhiqizwa ngokuyinhloko nge -catalytic hydrogenation ye-furan noma nge- butanediol dehydration . Ukukhiqizwa kwenziwa ngaphansi kokulawulwa kwekhwalithi okuqinile ukuze kuqinisekiswe:
Ukuhlanzeka okuphezulu kanye nokuqukethwe kwamanzi okuncane
Amazinga aphansi e-peroxide (amamaki azinzile noma angenayo i-peroxide ayatholakala)
Izakhiwo ezingokomzimba namakhemikhali ezingaguquki
Iqoqo ngalinye lihlolelwa ubumsulwa, okuqukethwe kwamanzi, nombala ukuze lihlangabezane nezindinganiso zezimboni nezaselabhorethri.
Isetshenziswa njenge-solvent ku -polyurethane, i-PVC, nokunye ukukhiqizwa kwe-polymer , iqinisekisa ukuxutshwa okufanele, ukuchithwa, nokucubungula.
Isebenza njenge-solvent and reaction medium in API synthesis, chemical intermediates, kanye nocwaningo lwesikali selabhorethri.
Iqashwe kuma-coatings, o-ink, nama-adhesives ngenxa ye-solvency yayo enhle kakhulu kanye ne-viscosity ephansi.
Isetshenziswa ku-organic synthesis, ukusabela kwe-Grignard, nezinye izinhlelo zokusebenza zaselabhorethri ezidinga i-solvent aprotic emhlophe.
Isebenza njenge-ejenti yokuhlanza kanye ne-solvent yokukhipha amakhemikhali amahle.
Ukupakisha Okujwayelekile:
200 L isigubhu sensimbi
1000 L ithangi le-IBC
Ukunikezwa Ngenqwaba: Kuyatholakala
Imibandela Yesitoreji:
Gcina endaweni epholile, eyomile, nendawo enomoya omuhle
Gcina iziqukathi zivaliwe futhi zivikelekile emithonjeni yokuthungela
Ama-peroxide inhibitors anconyelwe ukugcinwa isikhathi eside
Uketshezi oluvutha kakhulu
Sebenzisa izinto zokuzivikela ezifanele (i-PPE)
Gwema imithombo yomlilo nokushisa
Qinisekisa ukungena komoya ngendlela efanele
Bheka ku- Safety Data Sheet (SDS/MSDS) ngaphambi kokuyisebenzisa
Itholakala ngesicelo:
I-COA (Isitifiketi Sokuhlaziya)
I-SDS / MSDS

FIKA amadokhumenti okuthobela
✔ Ubumsulwa obuphakeme kakhulu bufanele izicelo zezimboni nezaselabhorethri
✔ Izinketho ezingenayo i-peroxide noma ezinzile ziyatholakala
✔ Ikhwalithi ye-batch engaguquki kanye ne-global supply chain
✔ Izinketho zokupakisha eziguquguqukayo kanye nokunikezwa kwenqwaba
✔ Ukusekelwa kwezobuchwepheshe kwezicelo zezimboni nezocwaningo
Q1: Ingabe i-THF ilungele ukukhiqizwa kwe-polymer?
Yebo, i-THF isetshenziswa kabanzi njenge-solvent ku-polyurethane, i-PVC, nezinye izinqubo ze-polymer.
I-Q2: Ingabe i-THF ingasetshenziswa ku-laboratory organic synthesis?
Yebo, i-THF iyincibilikisi ye-polar aprotic evame ukusetshenziswa ekuphenduleni kwe-Grignard nakwezinye izinhlelo zokusebenza ze-organic synthesis.
Q3: Ingabe unikeza amamaki angenayo i-peroxide?
Yebo, womabili amamaki azinzile nangenayo i-peroxide ayatholakala ukuze ahlangabezane nezidingo ezihlukene zohlelo lokusebenza.
I-Q4: Yiliphi inani elijwayelekile le-oda elincane (MOQ)?
I-MOQ incike ohlotsheni lokupakisha nendawo oya kuyo; sicela usithinte ukuze uthole imininingwane.
