Kugwiritsa Ntchito Zogulitsa
4-Methoxybenzoic asidi ankagwiritsidwa ntchito makutidwe ndi okosijeni ndi kuchepetsa cytochrome c mu njira kudzera osiyana-anasonkhana monolayers pa maelekitirodi golide ntchito cyclic voltammetry. Ndiwonso gwero lokhalo la kaboni ndi mphamvu zokulira mu zikhalidwe za Nocardia sp. DSM 1069. Kufotokozera Anisic acid kapena methoxybenzoic acid ndi organic compound yomwe ndi carboxylic acid. P-Anisic acid, yomwe imadziwikanso kuti 4-methoxybenzoic acid kapena Draconic acid, yomwe ndi methoxybenzoic acid m'malo mwa methoxy gulu pamalo C-4, ndipo P-Anisic acid ndi organic acid yokhala ndi kukoma kokoma. Ndi imodzi mwa isomers (m-anisic acid, ndi o-anisic acid) ya asidi anisic. Mawu akuti anisic acid nthawi zambiri amagwiritsidwa ntchito pofotokoza p-anisic acid ndipo P-anisic acid amapangidwa kudzera mu okosijeni wa p-cresyl-methyl ether. P-Anisic acid ndi asidi a carboxylic omwe amapezeka mwachilengedwe mu anise, chomera chamaluwa cha banja la Apiaceae. P-Anisic acid ilipo ngati crystalline solid cholimba chomwe sichisungunuka m'madzi, kusungunuka kwambiri mu mowa, komanso kusungunuka mu ether.
Phukusi Ndi Kusungirako
Phukusi:
25kg / katoni ng'oma kapena monga zofunika zanu.
Ndemanga: Kupanga kwa Chemical ndi kukula kwake kumatha kukonzedwa ndi zomwe makasitomala amafuna
Posungira:
Sungani chidebecho chotsekedwa mwamphamvu pamalo owuma, ozizira komanso olowera mpweya wabwino. Sungani padera pazotengera zazakudya kapena zinthu zosagwirizana.
Chitetezo cha Chitetezo
Njira zodzitetezera kuti musagwire bwino
Kusamalira pamalo abwino mpweya wokwanira. Valani zovala zoyenera zodzitetezera. Pewani kukhudzana ndi khungu ndi maso. Pewani kupanga fumbi ndi ma aerosols. Gwiritsani ntchito zida zopanda moto. Pewani moto woyambitsidwa ndi nthunzi ya electrostatic discharge.
