1. Tetrabutylammonium fluoride (TBAF) yog dav siv los ua cov tshuaj muaj zog hauv cov organic synthesis, tshwj xeeb tshaj yog rau kev tiv thaiv ntawm silyl pawg (Si-O, Si-C) thiab N-sulfonyl pawg nyob rau hauv cov tshuaj tiv thaiv me me nrog cov txiaj ntsig siab.
2. Tetrabutylammonium fluoride CAS 429-41-4 ua haujlwm zoo fluorinating tus neeg sawv cev hauv kev hloov pauv nucleophilic cov tshuaj tiv thaiv, ua kom muaj cov tshuaj fluorine rau hauv cov organic molecules los ntawm kev hloov halogens lossis nitro pawg, uas muaj txiaj ntsig zoo hauv tshuaj thiab agrochemicals.
3. Tetrabutylammonium fluoride yog ua hauj lwm raws li ib theem hloov catalyst thiab ua ib tug activator nyob rau hauv cross-coupling kev cuam tshuam xws li palladium-catalyzed coupling ntawm davhlau ya nyob twg alkynes nrog aryl halides, yooj yim synthesis ntawm arylated alkynes.
4. Hauv analytical thiab polymer chemistry, TBAF ua raws li cov khoom siv hluav taws xob hauv lithium- ion roj teeb thiab ua cov khoom siv hluav taws xob hauv cov txheej txheem polymerization los tsim cov fluorinated polymers nrog cov tshuaj tiv thaiv zoo thiab thermal stability.

1. Tetrabutylammonium fluoride yog hygroscopic heev thiab noo noo-sensitive; nws yuav tsum tau muab cia rau hauv lub thawv kaw nruj nreem nyob rau hauv inert cua (nitrogen los yog argon) nyob rau hauv ib tug txias, qhuav, thiab zoo -ventilated ib puag ncig ntawm 2-8℃los yog nyob rau hauv chav tsev kub nyob rau hauv lub ntim ntim.
2. Tetrabutylammonium fluoride CAS 429-41-4 yog cais nrog GHS teeb liab lo lus "Danger" thiab cov lus hais txog kev phom sij H314 (Ua rau cov tawv nqaij kub hnyiab thiab qhov muag puas), H225 (muaj kuab heev thiab vapor rau cov tshuaj THF), thiab tej zaum yuav ua rau mob ua pa (H335).
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg- cov hnab looj tes tiv thaiv (nitrile roj hmab), nruj nruj tsom iav kev nyab xeeb nrog rau sab- cov ntaub thaiv npog, tiv thaiv lub ntsej muag, thiab cov khaub ncaws tiv thaiv nplaim taws thaum tuav cov khoom no, ua kom muaj cua txaus hauv chaw ua haujlwm.
4. Khaws kom deb ntawm tshav kub, sparks, qhib nplaim taws, thiab cov ntaub ntawv tsis sib xws xws li cov oxidizing muaj zog, muaj zog acids, thiab cov hauv paus muaj zog; THF cov kev daws teeb meem yog cov nplaim taws heev (flash point -17 degree) thiab tuaj yeem tsim cov peroxides tawg thaum lub sij hawm raug rau huab cua.

1. Tshem tawm ntawm qhov chaw nchuav tam sim ntawd, xyuas kom muaj qhov cua txaus, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab hnav cov cuab yeej tiv thaiv tus kheej nrog rau tus kheej -cov cuab yeej ua pa (SCBA) thaum Tetrabutylammonium fluoride tso tawm.
2. Muaj thiab sau Tetrabutylammonium fluoride CAS 429-41-4 siv cov cuab yeej uas tsis muaj hluav taws xob thiab cov khoom siv tsis zoo xws li xuab zeb, diatomite, lossis universal binders; rau THF cov kev daws teeb meem, siv cov khoom pov thawj tawg thiab tsis txhob tsim vapors lossis pos huab.
3. Tsis txhob tsim cov plua plav lossis vapor huab cua thaum ntxuav kom tsis txhob ua pa; decontaminate qhov chaw thiab khoom siv los ntawm kev txhuam nrog cawv; Tsis txhob tso cai rau cov khoom nkag mus rau hauv cov dej ntws los yog cov chav dej.
4. Tshem tawm cov khoom pov tseg raws li cov khoom pov tseg uas muaj kev phom sij raws li hauv zos, xeev, thiab tsoomfwv ib puag ncig kev tswj hwm los ntawm kev tso cai ua kom puas tsuaj los yog tswj kev tua hluav taws nrog flue gas scrubbing.

1. Tetrabutylammonium fluoride nyob rau hauv THF tov yog heev flammable nrog ib tug flash point li ntawm -17℃mus rau 1℃F (kwv yees . -17 degree) thiab vapor siab uas muaj peev xwm tsim explosive sib tov nrog huab cua; daim ntawv khoom muaj NFPA kev ntsuas kev noj qab haus huv ntawm 3 (kev raug luv luv tuaj yeem ua rau raug mob hnyav).
2. Siv cov hmoov qhuav qhuav, cov pa roj carbon dioxide (CO₂), cawv- ua npuas dej tiv taus, lossis cov tshuaj tsuag dej los tua hluav taws uas cuam tshuam nrog cov khoom; Tsis txhob siv lub dav hlau dej ncaj qha raws li Tetrabutylammonium fluoride CAS 429-41-4 tuaj yeem tawg cov khoom kub thiab kis hluav taws.
3. Cov neeg tua hluav taws yuav tsum hnav tus kheej- muaj cov cuab yeej ua pa hauv siab- thov, MSHA/NIOSH tau pom zoo, thiab cov iav tiv thaiv tag nrho thaum tuav cov kub kub Tetrabutylammonium fluoride vim yog cov pa phem uas tsim los ntawm thermal decomposition .
4. Cov khoom puas tsuaj uas tsim nyob rau hauv hluav taws kub muaj xws li cov pa roj carbon monoxide, carbon dioxide, nitrogen oxides (NOx), thiab hydrogen fluoride; muaj cov hluav taws kub nyhiab los tiv thaiv ib puag ncig thiab muaj kuab paug.
