Iyini i-salicylic acid?
I-Salicylic acid iyisithako segxolo le-willow lesitshalo, futhi iyisithako semvelo sokulwa nokuvuvukala.
I-salicylic acid ivame ukusetshenziswa ekwelapheni izifo zesikhumba ezingamahlalakhona ezahlukahlukene kwezokwelapha isikhumba,njenge-acne (i-acne), i-ringworm njalo njalo.
I-salicylic acid ingasusa i-horny, i-sterilization, i-anti-inflammatory, okuyinto efaneleka kakhuluUkwelapha induna ebangelwa ukuvaleka kwemithambo, imikhiqizo yenduna eyinhloko yomhlaba wonkei-salicylic acid, ukuhlushwa kwayo kuvame ukuba ngu-0.5 kuya ku-2%.
Umsebenzi we-Salicylic acid
I-salicylic acid ingasetshenziswa njengezinto zokusetshenziswa kwemithi. Ukuze kulungiswe i-aspirin,i-sodium salicylate, i-salicylamide, i-analgesic, i-phenyl salicylate, kanye neminye. Imboni yokudaya ye-ukulungiswa kwe-moxibustion ephuzi emsulwa, i-3GN ensundu eqondile, i-acid chrome ephuzi njalo njalo.Iphinde isetshenziswe njenge-raber vulcanization retarder kanye ne-disinfectant preservatives

Ukusetshenziswa kwe-Salicylic acid
1. I-salicylic acid okungukuthi i-ortho hydroxy benzoic acid (i-o-hydroxybenzoic acid) uhlobo lwe-izinto zokwenziwa ezibalulekile zokwenziwa eziphilayo.Ekukhiqizweni kwezibulala-zinambuzane, isetshenziselwa i-Isocarbophos, i-organic phosphorus pesticide,i-isofenphos methyl intermediate isopropyl salicylate kanye ne-Rodenticide warfarin, ibulala amagundane i-etheri-coumarin ephakathi kwe-4-hydroxy coumarin; embonini yezemithi, i-salicylic acid yayisetshenziswa njenge-ama-antiseptic, futhi njengezinto ezihlanganisa i-acetylsalicylic acid (i-aspirin) neminye imithi; futhi iyi-antiseptic.izinto ezibalulekile zodayi, izinongo, njengemboni yerabha.
2. Isetshenziswa kakhulu njengezinto zokusetshenziswa ze-aspirin feedstock kanye ne-pesticide aqueous amine kanyeimikhiqizo ye-phosphorus, ingasetshenziswa nasembonini yokudaya, ekucwengisiseni nasekusebenziseni amakhemikhali, njll.
3. Isetshenziswa embonini yezemithi yokwelapha ukuqeda ukuvuvukala, ukudambisa ubuhlungu, kanye nokwelapha ukuvuvukala,imithi yokukhipha isisu, udayi wezimboni osetshenziselwa udayi we-azo ngqo kanye nodayi we-acid mordant, kodwa futhi nangezinongo, njll.
4. Isetshenziswa njengesibonakaliso esiyinkimbinkimbi kanye nesilondolozi.
5. Ukuqinisekiswa kwe-aluminium, i-boron, i-cerium, ithusi, insimbi, i-lead, i-manganese, i-mercury, i-nickel, isiliva,
i-titanium, i-tungsten, i-vanadium, i-sulfite, i-nitrate kanye ne-nitrite. Ukunqunywa kwe-aluminium, ithusi, insimbi,i-thorium, i-titanium kanye ne-uranium. Indlela ye-alkali kanye ne-iodometry titration standard. I-fluorescentinkomba. Inkomba ye-Complexometric.| Into | Inkomba |
