Mawu Oyamba
2,5-Dihydroxybenzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: 2,5-dihydroxybenzoic asidi ndi woyera crystalline ufa.
- Kusungunuka: Kutha kusungunuka m'madzi komanso muzosungunulira organic monga ethanol ndi chloroform.
- pH: Ndi yofooka acidic munjira zamadzimadzi.
Gwiritsani ntchito:
- Chemical kaphatikizidwe: 2,5-dihydroxybenzoic acid angagwiritsidwe ntchito ngati zopangira organic synthesis ndipo akhoza kutenga nawo mbali zosiyanasiyana zimachitikira mankhwala kukonzekera mankhwala ena.
Njira:
- Njira yokonzekera yomwe imagwiritsidwa ntchito kwambiri ndi kaphatikizidwe ka 2,5-dihydroxybenzoic acid ndi matenthedwe acidolysis a phthalic acid.
Zambiri Zachitetezo:
- 2,5-Dihydroxybenzoic acid ndiyotsika kwambiri pakuvulaza anthu ndi chilengedwe pansi pazikhalidwe zogwirira ntchito.
- Zitha kukhala zokwiyitsa komanso zowononga m'maso ndi pakhungu ndipo ziyenera kupewedwa pogwira. Ngati mwakumana mwangozi, muzimutsuka nthawi yomweyo ndi madzi ambiri.
- Pakusungirako, chisamaliro chiyenera kutengedwa kuti musagwirizane ndi ma okosijeni amphamvu, kutentha kwakukulu, ndi magwero oyaka moto kuti muchepetse zoopsa zomwe zingakhalepo.
