Mawu Oyamba
Acid ndi organic pawiri ndi mankhwala chilinganizo C6H4BrO2S.
Chilengedwe:
-Maonekedwe: asidi ndi woyera mpaka chikasu cholimba.
-Kusungunuka: Kusungunuka mu chloroform, acetone ndi chlorinated methane.
- Malo osungunuka: pafupifupi 116-118 digiri Celsius.
Gwiritsani ntchito:
- asidi ayenera kugwiritsidwa ntchito ngati yofunika wapakatikati mu kaphatikizidwe organic.
- Itha kugwiritsidwa ntchito popanga organic mankhwala okhala ndi thiophene mphete.
Njira Yokonzekera: Pali njira zambiri zopangira
-anacid. Njira imodzi yomwe imagwiritsidwa ntchito kwambiri ndikugwiritsa ntchito bromoacetic acid ngati zopangira, kuchita ndi thiophene pansi pamikhalidwe yamchere kuti apange 3-bromothiophene, kenako kuchita carboxylic reaction pansi pa acidic.
Zambiri Zachitetezo:
- asidi akhoza kukwiyitsa maso, khungu ndi kupuma dongosolo.
-Pogwiritsa ntchito, samalani kuti musapume fumbi kapena kukhudzana ndi khungu ndi maso.
-Valani zida zodzitetezera zoyenera monga magolovesi a labu, magalasi ndi zishango zakumaso musanagwire ntchito.
-Mukakhudza khungu kapena maso, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala. Njira zoyenera zothandizira chithandizo choyamba zidzaperekedwa ngati kuli kofunikira.
