Kev siv
Organic synthes intermediates:
Grignard reugent kev npaj: {{{4- bromoosisole reacts nrog cov organic sib xyaw ua ke xws li benzoic acid thiab acetophenone.
Suzuki Coupling Event: Raws li ib qho catalyst, nws koom nrog kev tsim cov pa roj carbon-carbon politures hauv cov tshuaj thiab cov khoom siv science.
Cov Ntaub Ntawv Kev Nyab Xeeb
Cov phom sij:
Irritant: hmoov av lossis vapor yuav ua rau lub cev ua pa thiab tawv nqaij. Tam sim ntawd yaug nrog dej ntau tom qab kev sib cuag.
Flammability: Flash taw tes 98 degree (kaw lub khob), tso roj rau hydrogen zoo xws li kub hnyiab, thiab xav tau kom nyob deb ntawm cov nplaim taws thiab qhov kub.
GHS kev faib tawm: mob toxicity - hauv ncauj (qeb 4), tawv nqaij 4), tawv nqaij 4), muaj teeb meem rau dej ua lub neej (H412).
Kev tiv thaiv kev ntsuas:
Hnav cov hnab looj tes tiv thaiv kev tiv thaiv, tsom iav thiab cov npog qhov ncauj qhov ntswg thaum ua haujlwm kom tsis txhob muaj kev sib cuag.
Khaws rau hauv qhov chaw txias thiab qhuav, ntim los tiv thaiv kev nqus dej noo lossis oxidation.
