Kodi salicylic acid ndi chiyani?
Salicylic acid ndi chomera cha msondodzi chochotsa makungwa, komanso anti-yotupa mwachilengedwe.
Salicylic acid amagwiritsidwa ntchito pochiza matenda osiyanasiyana akhungu mu dermatology,monga ziphuphu zakumaso (ziphuphu), zipere ndi zina zotero.
Salicylic acid imatha kuchotsa nyanga, yotseketsa, yotsutsa-kutupa, yomwe ili yoyenera kwambirizochizira ziphuphu zakumaso chifukwa clogs, mayiko ambiri ziphuphu zakumaso mankhwala ndisalicylic acid, ndende nthawi zambiri ndi 0,5 mpaka 2%.
Ntchito ya salicylic acid
Salicylic acid imatha kugwiritsidwa ntchito ngati mankhwala opangira mankhwala. Kukonzekera kwa aspirin, sodium salicylate, salicylamide, analgesic, phenyl salicylate, ndi ena. Makampani opanga utotokukonzekera moxibustion koyera yellow, mwachindunji bulauni 3GN, asidi chrome yellow ndi zina zotero.Amagwiritsidwanso ntchito ngati mphira vulcanization retarder ndi mankhwala osungira

Kugwiritsa ntchito salicylic acid
1. Salicylic acid yomwe ndi ortho hydroxy benzoic acid (o-hydroxybenzoic acid) ndi mtundu wazofunika organic kupanga zopangira.Popanga mankhwala, amagwiritsidwa ntchito popanga mankhwala a organic phosphorous Isocarbophos,isofenphos methyl intermediate isopropyl salicylate ndi Rodenticide warfarin, kupha makoswe ether wapakatikati 4-hydroxy coumarin; m'makampani opanga mankhwala, salicylic acid amagwiritsidwa ntchito ngati antiseptics, komanso ngati intermediates acetylsalicylic acid (aspirin) ndi mankhwala ena; ilinso ndizinthu zofunika zopangira utoto, zokometsera, monga mafakitale a labala .
2. Amagwiritsidwa ntchito makamaka ngati zopangira za aspirin feedstock ndi mankhwala amadzimadzi amine ndimankhwala phosphorous, angagwiritsidwenso ntchito mu makampani utoto, kuyenga ndi reagent mankhwala, etc.
3. Amagwiritsidwa ntchito m'makampani opanga mankhwala a antipyretic, analgesic, anti-inflammatory,mankhwala okodzetsa, utoto wamafakitale womwe umagwiritsidwa ntchito mwachindunji ku utoto wa azo ndi utoto wa acid mordant, komanso zonunkhira, ndi zina.
4. Amagwiritsidwa ntchito ngati chizindikiro chokhazikika komanso chosungira.
5. Kutsimikizira kwa aluminiyamu, boron, cerium, mkuwa, chitsulo, lead, manganese, mercury, faifi tambala, siliva,
titaniyamu, tungsten, vanadium, sulfite, nitrate ndi nitrite. Kutsimikiza kwa aluminiyumu, mkuwa, chitsulo, thorium, titaniyamu ndi uranium. Njira ya alkali ndi iodometry titration standard. The fulorosenti chizindikiro. Chizindikiro cha Complexometric.| Kanthu | Mlozera |
